The Force in Star Wars gives people the power of telekinesis. Near the end of the episode, Freeman says, " In Star Wars, you can use the Force to hear the voices of people who aren't here anymore."
LIGO is in the American states of Louisiana and Washington; LIGO rules out earthquakes and other local forces in its search for gravitational waves from outer space. Quantum entanglement appears to be non-local! Anton Zeilinger does an experiment for this episode at the Hofburg Palace in Vienna, Austria. With his De Broglie–Bohm theory in 1952, David Bohm proposed that quantum particles follow predictable paths. According to Damien Easson, the essence of loop quantum gravity (LQG) is that "empty space itself is made out of quantum bricks of nothing."

00:00Space, a vast, empty ocean, where a planet like ours is a remote island, alone in the void, or is it?
00:17New research is beginning to unveil a hidden force, one that shakes the entire universe
00:24and penetrates space with trillions of invisible connections.
00:30Instantly linking every place in our world and joining our future with our past.
00:39Now we're beginning to grasp these mystical powers.
00:44Is the Force with us?
00:52Space, time, life itself.
00:56Space, time, life itself.
00:57Space, time, life itself.
00:58Space, time, life itself.
00:59The secrets of the cosmos lie through the wormhole.
01:03Space, time, life itself.
01:07Space, time, life itself.
01:12Space, time, life itself.
01:16Space, time, life itself.
01:17You know the story.
01:18A long time ago, in a galaxy far, far away, there was a mysterious force surrounding us, penetrating us, binding the galaxy together.
01:24surrounding us penetrating us binding the galaxy together if you could wield
01:31this force you could do astonishing things seem like a Hollywood fantasy
01:42well scientists now wonder whether something like the force could be real
01:47could there actually be a mystical power that spans the universe connecting and
01:54binding all things
02:00astrophysicist Jamie Rollins has spent his career listening to the universe trying to
02:07detect a mysterious force one we've never been able to see over the course of the
02:14history of astronomy light has essentially been our only way of learning
02:19about the universe what we see out there is influenced by forces coming from
02:25things that we don't actually directly observe it's like walking around without
02:31being able to hear we know that there are sounds and we know that we could learn a
02:35lot from them if we could hear them there is no sound in the vacuum of space but according to Albert
02:45Einstein gravity affects space in a very similar way to sound we've been able to demonstrate many of
02:55the predictions of Einstein's general theory of gravity the one big one that we
02:59haven't is the fact that there should be waves of gravity gravitational waves are
03:05one of Einstein's most elusive predictions he believed that space is not truly empty but
03:12acts like a kind of substance that can be warped by masses like stars and galaxies
03:18and when massive objects move suddenly they send ripples across space squeezing and stretching
03:28everything they encounter from planets to the people living on them detecting these gravitational waves
03:37would prove that we are physically joined to the cosmos by a fabric of space and that events
03:44across the universe exert a tangible force on us but detecting this force is no
03:49easy task the waves that pass through the earth are essentially unfathomably small we
03:56have to make incredibly sensitive detectors to be able to experience this effect LIGO the
04:04laser interferometer gravitational wave observatory is one of the world's biggest
04:10scientific experiments each of its arms is four full kilometers long to rule out earthquakes and other
04:20local forces LIGO has two separate detectors one in Louisiana one in Washington state LIGO compares the way
04:30two high-powered laser beams move up and down each of its long arms mirrors at the end of each one
04:37bounce the laser beams back to the center where they're compared by computers as long as the links
04:44of the two arms are exactly the same then the light going into the two arms will come back and be exactly
04:50in sync if a gravitational wave passes through the earth it would cause the arms to squeeze and stretch
04:58throwing the lasers out of phase with each other Jamie is one of LIGO's more than 1,000 scientists and for
05:07him the principle by which the detective works is very familiar as a former DJ he's used to
05:17listening to tiny discrepancies in sounds let's say I've got two identical records that I've started
05:24at the exact same time such that the songs are exactly synchronized together we were to disturb one
05:30by say dragging my finger along the side then this record would fall out of phase with the other one which
05:37would produce a shift in the sound that we can hear if you're listening to one record you might not notice that
05:45effect now if we were to beat up one record and slow down the other the songs come in and out of phase with each other this is very
05:57similar to what happens to the light in the arms of the interferometer the changes in length that
06:05we're looking for are so minuscule they're smaller than the nucleus of a single atom it's completely
06:13imperceptible to the normal physical world that we experience but in September 2015 after more than two
06:21decades of development and more than a billion dollars LIGO finally detected a ripple in space it sensed a
06:30staggeringly violent event one that took place a long time ago in a galaxy a billion light years away
06:39what we detected was a binary black hole system which is two black holes that are in a tight orbit around
06:49each other in fact at the very end of their lifetime as a binary system as the two black holes spiraled
06:57together and collided the fabric of space shuddered and a billion years later LIGO felt it
07:08to Jamie that ripple in space is truth that gravity connects everything in the universe it was incredibly
07:16gratifying but it's also the excitement to know that there's so much to be learned by having this new
07:25sensory perception in the universe it's really as if we're connected to the rest of the universe in a
07:31totally different way one omnipresent force the force of gravity binds the universe together but how
07:40does gravity actually connect planets stars and people cosmologist Claudia Durang is taking aim at the
07:53the elusive substance of gravity itself for all the forces that we know there's a particle
08:02associated with that force which is responsible for carrying the force through empty space when
08:08i bring that magnet close to the horseshoe i can feel the magnetic force and for the magnetic force
08:14electric force the particle is the photon it's not visible light but it's there nonetheless
08:20and one of the great mysteries of physics today is whether there's a particle associated with the
08:26gravitational force
08:34Claudia is obsessed with finding gravity's hidden mechanism how does this mysterious force stretch
08:41across the cosmos silently tugging on everything but gravity is not easy to study because of all the
08:49forces we know gravity is the weakest we think of gravity as this huge powerful force that keep us glued to
08:58the surface of the earth but actually it's remarkably easy to overcome all it takes is a few fans
09:03right now a powerful wind is pushing claudia away from the earth molecules of air are hitting her body and forcing it upward but something else is forcing her down
09:18you could almost picture a tractor beam pulling me down and the funny thing is in physics we're having a huge debate on whether gravity is a force or not
09:34according to einstein there is no force of gravity pulling on these skydivers the huge mass of the earth
09:42simply distorts the shape of space near it and they follow the contours of that shape
09:48but quantum mechanics has a different approach according to this theory of the most fundamental particles
09:56something really is passing between the skydivers and the earth identical little chunks of gravity called
10:03gravitons right now i'm exchanging gravitons with the earth they're traveling between the earth and me
10:13if we could see gravitons we'd see tractor beams everywhere making hidden connections between everything that has mass
10:23claudia believes these graviton tractor beams keep us all stuck to the earth at least when we're not in a wind tunnel
10:33but they have never been detected in any scientific experiment it's extremely hard to catch a graviton
10:40when a graviton comes it just goes straight through me
10:44to detect the particles which carry forces we build particle accelerators
10:50but if those forces are weak we must build enormous particle accelerators
10:55and gravity is trillions of times weaker than electromagnetism
11:03you could think of needing to have a detector of the mass of jupiter parked in orbit around a neutron star
11:11to have enough mass there to have maybe the chance of detecting one or two gravitons every century
11:18and that's being very optimistic but if we could find the graviton and learn to manipulate it
11:25we'd have in our hands a seemingly supernatural force just as we focus photons into laser beams
11:33we could focus gravitons into beams of gravity it's a new world manipulating the photon on an everyday
11:41basis so who knows what would be possible if we were able to capture the graviton
11:49and then manipulate it
11:55gravity holds everything in our universe together
11:58but the gravity between anything with giant objects is incredibly weak
12:03a tiny action over here could never create a reaction over here or could it
12:18distance it's such a basic idea we don't even think about it but because we have distance
12:25that object is too far away for me to knock over but now suppose i had a double someone i'm truly deeply connected to
12:38i could cause something far away to happen instantly
12:45could such a power exist in the universe
12:48quantum physicist anton zeilinger studies a strange phenomenon called entanglement entanglement
13:01means that two particles which have interacted are connected in a very interesting way such that
13:07measurement on one changes the quantum state of the other one the particles of the quantum world are as
13:15unpredictable as playing cards they can spin and vibrate in many possible directions when we measure
13:23these properties we get random results but according to quantum theory when two particles are entangled
13:31their results will always match as if the particles could somehow talk to each other in a nutshell we have
13:39two particles and i make measurements on them the result on each of them is completely random but the two are the same
13:51how can two random events always be the same strangers still entangled particles seem to remain connected
14:01no matter how far apart they are the idea that objects must be nearby to affect each other
14:09is what physics calls locality so if we consider a stack of papers then locality would mean that if i kick
14:17one over the others also fall over but entanglement appears to be non-local which means that distance is
14:26irrelevant non-locality would mean that if these papers fall over by themselves something else might happen
14:34like this picture falling over at the end of the room on the roof of his institute in vienna anton has
14:45deployed a powerful laser to test entanglement over long distances what we do here is we create photon pairs
14:53we keep one photon locally and the other one is sent to a measurement station which is about three miles away
15:01after moving his entangled photons far apart anton measured them both at the exact same time
15:13every time he does this he sees the same eerie coincidence the particles give matching answers
15:21to see if it matters how far apart they are anton has performed this experiment over ranges longer than 90 miles
15:31if the theory of non-locality is correct the connection between entangled particles is literally
15:41instantaneous even if they're across the universe
15:44to one of the greatest minds of the 20th century the idea of instant connections seemed to defy the laws
15:53of physics einstein was always critical about quantum mechanics for two reasons one was the randomness
16:01of individual events and the second was entanglement he said that there cannot be spooky action at a distance
16:06he saw in his experiments was a genuinely spooky force at vienna's hofberg palace he found a sprawling sub
16:22basement that gave him room to work and we are here in the second basement in the lowest basement which we
16:29chose because it has long hallways these are the longest hallways in vienna and furthermore the environment
16:37is very stable very little vibrations it's very quiet this hallway is so long that even light takes a full
16:46billionth of a second to cross it when anton shoots entangled photons toward the opposite ends of this hallway
16:53his super fast equipment has time to measure both photons faster than light can beam a message between them
17:02we measure them really simultaneously so fast that there's no time that they could have talked to each
17:09other and told each other what happens
17:15anton proved that entanglement makes an instant connection
17:19somehow two far away places can be linked in a way that defies explanation could a spooky distant
17:29force also affect us and the events in our lives according to this man it can in fact it could be the
17:40reason reality exists we are made of tiny magic particles entanglement gives every one of them the power to make
17:53connections that reach instantly across the universe but if the particles in our bodies can do this
18:02why can't we do it ourselves and why does our world look so ordinary
18:10if a mystical force is connecting distant points in the universe where do we fit in
18:23good morning toronto your weather forecast today a 50 chance of rain
18:30tiny quantum events are all around us happening at every single moment
18:35quantum physicist ephraim steinberg can't see them any better than the rest of us
18:44but he believes we feel that the facts we all go and listen to the weather forecast
18:49and at best they tell us 50 chance of rain 60 chance of rain we just don't know enough
18:55according to the standard view of quantum mechanics there's a kind of quantum weather out there where we're
19:00always doomed to have predictions that are only probabilistic 50 chance of this 50 chance of that
19:07according to ephraim there's reason to suspect we don't fully understand the quantum world
19:13and that reason is its randomness
19:18it's these random particles of the quantum world that can entangle with each other making instantaneous
19:25connections we know that entanglement means there's a sort of hidden connection
19:29it's a mysterious kind of connection that we can't describe mechanistically no one understands
19:35why it should be that the universe seems capable of speaking to itself instantaneously across huge
19:40distances while whenever we try to communicate we're limited to speaking no faster than the speed
19:45of light if i leave home in my car in the morning and i get to work half an hour later
19:51we all believe that you could tell me where my car was every instant of the way along that path
19:56quantum mechanics is different it doesn't have this concept of a trajectory
20:02it was in a famous experiment called the double slit where the trajectories of quantum particles first
20:09went missing in this experiment light travels towards a pair of slits so that each photon each particle
20:16of light might be expected to choose either take the left slit or the right slit but offer a photon a
20:22choice of two slits and it appears to choose both of them if it was a car we could determine that car would
20:30either turn left or turn right it couldn't do both but cars and photons are different in another way
20:38you could watch a car but you can't watch a photon so we'd all love to see how the photon pulls
20:44off this trick but when you think about what it takes to observe something you realize that there's
20:48no such thing as passive observation for you to see an object you must bounce light off of it but if
20:55what you're trying to see is a particle of light you destroy what you're looking at the normal view of
21:04quantum mechanics is to say that we simply cannot ask which slit an individual particle goes through
21:10we can't talk about how they get from place to place all we can talk about is the probabilities
21:15for where they end up when we observe them at the end of the day
21:22while we move in predictable paths we are made of particles that seem to skip around at random
21:29or so quantum theory asks us to believe but it's not the only interpretation of what's happening
21:35back in 1952 a physicist named david bohm proposed that quantum particles might actually follow
21:43predictable paths but only if we accept that faraway forces are shaping their trajectories
21:51ifram decided to investigate this idea he set out to redo the double slit experiment to see whether the
21:59faraway force called entanglement might offer a more sensible explanation of how particles move nowadays
22:05we have techniques that allow us to actually measure what a photon's doing while it's in flight we don't
22:10want to do this by catching the photon and interrupting its trajectory if it has one instead we do it using the
22:16magic of entangled particles when two particles entangle they become perfect mirrors of one another
22:24so one can tell you what the other is doing imagine two cars that are identical in every way even down to
22:32the turn signal maybe as car a rides off into an intersection we can't follow it and see which way it turns
22:39but we can always look at car b and if its right blinker is turning we conclude that car a should turn to the right
22:45like the two slits in the experiment two roads lead away from this intersection turn left and you get to a
22:57church turn right and you get to a fountain ifram can't watch which road his car will choose
23:07but by watching the car it's entangled with he can guess its destination
23:12but once again photons aren't like cars even knowing which way they turn will steer you wrong
23:20half the time does randomness win the day after all or is something happening after the intersection
23:29ifram used entanglement to keep on watching it's as though even though i can't follow the car through
23:35the intersection and measure exactly where it is at every instant i can get just a little bit of
23:40information about where it is now where it is a moment later and build up a trajectory as the photon
23:47moved toward its destination ifram watched his entangled partner it didn't just tell him where the other
23:54photon went it actually influenced the other's trajectory it was as if they were connected by an unseen
24:03force the two particles were collaborating to form a trajectory just like the ones we see we know
24:10based on the theory of entanglement that entangled particles are forever influencing one another
24:15to understand what one entangled car is doing we must also know what the other entangled car is doing
24:21i can't lift up my hand and cause an apple on the other side of the quad to rise up off the ground
24:27and yet the world is simply interconnected the universe seems to be busy talking to itself
24:32instantaneously all the time remember how in star wars the force is with you even if you aren't aware
24:41of it while i stand here experiencing plain old reality the particles i'm made of might be communicating
24:49with particles billions of light years away it's a magic trick we do in every moment and science is
24:57starting to get an idea how it works
25:07hello hello oh you again yeah i was hello
25:13when we humans communicate over distance there has to be something connecting us whether it's a phone
25:23line or radio signal but entanglement doesn't seem to work that way it just happens there is no phone line
25:34or can we just not see the cord
25:50theoretical physicist daniel cavett thinks a lot about distant connections
25:55and the hidden ways they might work quantum entanglement is one of the most mysterious properties
26:02of quantum mechanics you might think that two things that are widely separated would have their
26:07own independent existence but according to quantum mechanics that's really not true objects don't
26:12have an independent existence of their own quantum mechanics ties them all together in quantum mechanics
26:19instant connections are everywhere but we can't use those connections when we want to go somewhere
26:26we still have to walk our concepts of distance and time are so fundamental that we don't think of them as concepts at all
26:38we think of them simply as reality the set of rules which everything in the universe must follow
26:45hey i called in an order uh daniel
26:49pastrami rubin excellent thanks enjoy if we want to get somewhere we have to pass through space
26:58i got the cheesecake if we change our minds about a lunch order hello juniors we have to cross that
27:05same space again can i get a slice of cheesecake but according to some physicists there are faster ways to go
27:12a wormhole is like a filament of space that connects into distant points not by the route that we'd normally travel
27:23it's a shortcut where you'd go out of our ordinary space and then reappear somewhere else
27:29i got my cheesecake wormholes connect two distant places faster than light could move between them
27:36while there's no direct evidence wormholes exist the same kind of connection links two entangled particles
27:44one idea is that this connection is actually a reflection of quantum entanglement wormholes and
27:51quantum entanglement are very similar to each other could well be two different sides of the same coin
27:58daniel thinks wormholes might be the secret shortcuts by which entangled particles communicate
28:03and if these connections exist the universe may be filled with them
28:15you could think about the early universe as a hot molten blob
28:19as it expanded and cooled the space we see began to take form
28:24the surface of the globe is the universe we experience there is nothing inside or outside at least that's the
28:36usual portrayal the yearly universe started out small hot and dense filled with particles as they
28:45interacted with each other this created entanglements quantum connections between the different particles that
28:51were present in the early universe and as the universe expanded those connections weren't lost they left traces behind
29:01like the threads passing through this globe the hidden legacy of creation might be a network of wormholes
29:10but if wormholes are everywhere why don't we sense their existence
29:15daniel thinks we do let's imagine that we had a huge number of particles
29:22all with quantum entanglement and then we'd have a very dense network of wormholes connecting
29:27all of these particles if you looked at that network
29:31and looked at it a bit from a distance it might look to you very much like the space and time that we observe
29:37the space around us might be filled with hidden connections dating back to the creation of the universe
29:46but could new connections still be forming
29:50one scientist thinks gravity itself could be making them
29:56in the universe's darkest places
29:59two vastly different powers are at work in our universe
30:11while gravity can warp the space between distant galaxies
30:16entanglement acts like space and distance do not exist
30:21today science is seeking a theory of everything that ties together gravity and the forces of the quantum world
30:29could gravity and entanglement be manifestations of the same thing
30:36could there be a master force
30:43for astrophysicist damien eason the first step towards the theory of everything
30:49is a strange one figuring out what empty space is made of nobody really knows what empty space is
30:56but we know that at least what we would think of as empty space is filled with energy
31:03damien works on a theory called loop quantum gravity which contends that nothing is not really
31:11nothing the core idea in loop quantum gravity is that empty space itself is made out of small quantum
31:16bricks of nothing the size of these bricks is incredibly small much much much smaller than an electron
31:24or proton or other particles that we know about but we believe nothing can actually collapse any smaller than that
31:31physicists think a lot about collapsing because there are places in the universe where the force of gravity
31:38is said to crush things down to nothing black holes are one of the great mysteries of science
31:46scientists they form when massive stars run out of fuel without the outward push of nuclear combustion
31:54they collapse under the pull of their own gravity around the black hole the gravitational pull is so
31:59strong that even light can't escape hence we call it a black hole inside a black hole many scientists think
32:08matter is crushed down to no size at all but how could that be possible if space itself is made of
32:17uncrushable bricks of nothing in places like this junkyard you'll find some powerful man-made forces
32:27this industrial size crusher applies more than a ton of pressure to every inch of the car inside
32:32but as the car gets more compacted the machine becomes less and less effective
32:43gravity is different if it was only up to gravity this car would collapse and get smaller and smaller
32:50and smaller eventually some people believe so small that it would be an infinitely dense point
32:56and that's what we call a singularity if singularities are real they'd be great places to make connections
33:06inside one the distance between things shrinks down to nothing everything overlaps with everything else
33:14distance and time simply cease to exist but could this actually happen in black holes
33:21in black holes damien is not certain when we fall into a black hole according to conventional wisdom
33:28the forces of gravity become so strong that things are ripped apart and the laws of physics as we
33:33understand them break down we know however though that since the singularity is an incredibly small space
33:41some other theory some theory of quantum gravity must have to kick in
33:45black holes are like the clown cars of the universe where everything gets uncomfortably close together
33:57damien thinks that when the force of gravity meets the tiny quantum world
34:01some funny things might happen all right now imagine this part of the balloon represents the space inside
34:07of a black hole if we fall into the black hole gravity becomes stronger and stronger space becomes more and
34:14more compressed and more compressed and this is the point where a passageway opens up into a new universe
34:20the passage between the old universe and the new universe is what we call a wormhole
34:26where some people see a singularity damien sees a wormhole a secret door to another realm
34:35while we know gravity brings things close together
34:38it may also do what entanglement does build connections between distant places according to this
34:47theory entanglement and gravity may work together as a single force connecting everything and joining our
34:56universe with many other ones we believe that there are black holes on the inside of all the hundred billion
35:02galaxies that we observe it's quite possible then that within each of these black holes is an entirely new
35:09universe connected to our universe by a wormhole our universe may be just one among billions all bound
35:19together by a single master force but this scientist thinks that same force also unites all times
35:29and we could use it to send messages to the future
35:38ever have that feeling that the past isn't really gone or that someone you've lost is right here with you
35:47those mysterious feelings of connection are what keep fortune tell us in business
35:51others but entanglement and gravity tell us things are eerily connected
36:01in star wars you can use the force to hear the voices of people who aren't here anymore
36:08when we feel the presence of things gone by
36:11have they really gone by or are they still with us
36:31boys estate physicist jay olson thinks we never walk alone because in the entangled universe
36:37everything that has ever happened is still with us so this stadium is almost half a century old
36:46teams have played here many games have been won and lost just being around it you can feel that
36:51there's a lot of history that is played out here jay likes to watch football scrimmages
36:59he doesn't attend them religiously but the way he understands the universe you don't have to
37:08go to just one scrimmage and you'll experience many others the universe is all of space and all of
37:15time simultaneously the past is correlated with the future and so that information never really goes
37:22away it's always encoded throughout all time think of the universe at this very moment like this stadium
37:33fast cold and virtually empty a really big game the big bang itself happened here 13 billion years ago
37:45a lot of entanglement was generated early on because the density was high there were lots of particles
37:50bumping into each other flying off carrying these deeper than normal connections
37:58and as the universe spreads out the matter spreads out too even these particles that are
38:02separated by vast distances can still be entangled with one another and after the big bang the
38:08connections keep on multiplying as entangled particles swap their experiences
38:14to swap entanglement in the lab scientists start with two pairs of entangled particles
38:22by introducing just one particle from each pair they can entangle their distant partners
38:32you could think of this in terms of human couples
38:36jay met his wife ping because they were in the same town at the same time
38:41they decided to get entangled but ping sometimes skips the football scrimmages
38:49now suppose things get exciting at a particular practice
38:54and jay entangles with his neighbor not only are they late but so are the partners they were entangled with
39:02even though they'd never met each other they are now instantly connected weird as still connections
39:11like this can form between the future and the past entanglements don't just cross space they can also
39:17cross time and we call this time-like entanglement suppose it was 10 years earlier jay's football buddy was
39:26entangled back then but jay wasn't fast forward 10 years and a lot of things are different jay met ping
39:37while his buddy got divorced our human perspective says we can only share experience if we are there
39:44at the same time that moment wouldn't affect your wives at all especially if one of you is no longer
39:52marriage but to entanglement time doesn't matter it simply connects one wife from the present with
39:59the other from the past this is true even though they never had the opportunity to meet and something
40:04that happened to buddy's ex 10 years ago could happen to my wife today
40:12the entangled universe is a timeless place
40:15where the present is deeply connected to the future and the past
40:23jay thinks we could see those connections if we built a special detector it's possible to generate
40:29a detector that kind of looks at time slightly differently it doesn't see exactly what your eye
40:35sees it sees something else like a jedi uses the force to see people who aren't here anymore
40:42we too could see the instantaneous links uniting all of time and jay thinks we could tap this hidden
40:50network what we know is that this is a an interesting property that nature is giving us you could send
40:57information into the future while skipping the time in between to send his message across time jay would
41:06encode it in a quantum state and pass it to a particle entangled with the future the message disappears
41:14but it's not gone it's merely skipping over what we humans experience as time it could be two billion
41:21years or it could be two years we could say two years if i want to be around to see it two years later
41:27omaha its moment is approaching with her special detective ping can now receive the message jay left
41:36for her two years ago
41:42if we can send messages across time could we someday send ourselves the fact that that entanglement exists
41:49between time people have barely begun to think of what that might be able to do if you could send the
41:54state of one atom in principle you could do two or ten or a million or even an entire human body or mind
42:05will we someday harness the power to skip across time and space or the power to move distant objects
42:13without ever touching them sounds like make-believe but such powers do exist and they're already at work
42:22inside us as we seek to understand gravity and entanglement we are taking our first steps toward
42:31abilities we have only dreamed about toward deeper understanding of our oneness with the universe
42:39abilities there may be no such thing as the force from star wars
42:48but we have our own that's just as amazing
42:56the force is truly with us
