00:00Well, it turns out the universe is like those thousand-piece puzzles.
00:05It has a missing piece, too.
00:06And while you gotta look somewhere behind the couch for a puzzle piece,
00:10the universe's lost chunk might be right above us, in the Earth's atmosphere.
00:16There are hints that it contains something scientists have been trying to find for years.
00:20Dark matter.
00:22Dark matter is an invisible type of matter.
00:25It plays a huge role in creating our world.
00:27Like sticky glue, it helps entire galaxies come together,
00:31grow into enormous cosmic structures, and rotate.
00:35Unfortunately, it's impossible for us to study it properly,
00:38because we haven't managed to detect it yet.
00:41But recently, a new idea appeared that might help us finally catch this secret Pokemon.
00:48What if we were trying to detect it the wrong way?
00:51Usually, astronomers imagine dark matter is something made up of massive particles.
00:56But now they think that it might be made of tiny, light particles,
01:00possibly even a million times more delicate than the lightest particles we know.
01:05In that case, it could flow through the world like cosmic waves.
01:09And this gives an idea of how to spot them.
01:12Scientists want to try using Earth's ionosphere,
01:15the upper layer of our atmosphere that's packed with charged particles.
01:19That's where all of our beautiful auroras come from.
01:22The charged particles light up when the sun particles touch them.
01:25They figured that it might interact with these particles, emitting radio waves,
01:30finally letting us know that we're not crazy and it's really out there.
01:35Here's how it would work.
01:36If their idea is true, then the dark matter is kind of like an invisible ocean.
01:41It's ultralight, basically weightless, and it's gently sloshing around the universe.
01:46So it should occasionally pass through our planet as well.
01:50We just don't notice it.
01:51The waves travel through the Earth's ionosphere with all its charged particles.
01:56And if at that moment their vibrations line up, it creates resonance.
02:00This resonance makes their interactions even stronger and stronger.
02:04Kind of like pushing someone on a swing makes them go higher.
02:07In this way, their interaction would finally become strong enough for us to notice and detect.
02:13For the first time, we might be able to detect electromagnetic radio waves sent by dark matter.
02:20All that's left for us to do is to catch this with super powerful antennas.
02:24The ionosphere is our best friend that has always helped us catch tons of other radio waves.
02:30So let's hope it works this time.
02:31The reason why dark matter is invisible to us is that it doesn't emit, absorb, or reflect light.
02:39Regular matter, all the things that surround us, absorb some light waves and reflect others,
02:44which makes us see them in different colors.
02:47But dark matter particles don't do that, so we have no idea what this substance looks like.
02:52And as we mentioned, it's probably super light.
02:55So because of this, it interacts very weakly, if at all, with normal matter.
03:00It could pass right through you and your walls, and nothing would happen.
03:04No friction, no heat generation, no sound.
03:07We can't even catch the particles bumping into each other or interacting in other ways.
03:12So telescopes can't catch it.
03:14Detection tools that rely on radiation fail as well.
03:17It's invisible to electromagnetic detection, including infrared, ultraviolet, x-rays.
03:24So how in the world do we even know that it's there?
03:27Well, it's all because of mass and gravity.
03:32So first of all, our galaxies wouldn't exist at all without it.
03:36We know that the gravity of different objects can hold them together.
03:40But when scientists studied galactic clusters and summed up all the objects in them,
03:45they realized that something doesn't add up.
03:47All the visible mass in galaxies, like stars and gas,
03:51wasn't enough to keep these clusters bound together.
03:54They move so quickly that they should fly apart.
03:57Next, they started to look at how galaxies rotate.
04:01Again, they noticed something strange.
04:03That the outer parts of galaxies rotate almost as fast as the inner parts.
04:08Imagine the runner tracks.
04:10We know that guys on the outer tracks should run faster
04:13to catch up with those who are closer to the center.
04:15People around the center go a shorter distance and run faster.
04:18Our galaxies form spirals.
04:21So it should be logical that stars and planets move faster near the center, right?
04:26But they don't.
04:27For some reason, they move almost at the same speed.
04:31Something must be pushing the outer parts to move.
04:35Then we noticed gravitational lensing.
04:38When light travels around huge and massive objects,
04:40it gets bent for some reason.
04:42But it shouldn't do that.
04:44Even though these objects are massive,
04:45are they really massive enough to bend light?
04:49All these things hint at one.
04:50There must be some invisible type of matter
04:53that adds to the weight and gravity of our universe.
04:56This invisible extra mass
04:58helped clusters of galaxies deform
05:00and distribute across space in certain patterns.
05:03Alternate explanations just don't work.
05:06When scientists create timeline simulations of the universe after the Big Bang,
05:10things only line up after adding this invisible matter to the equation.
05:14So they called it the dark matter
05:17and then realized that this invisible part
05:20makes up about 85% of the mass of our world.
05:24That means that for about every 2 pounds of regular matter,
05:27there are 11 pounds of dark matter.
05:30Wow.
05:31Try not to think of the ramifications of that
05:33the next time you step on the scale.
05:35But what exactly makes up dark matter?
05:39That's an interesting question.
05:41Which is why I said it.
05:43At first, scientists were looking for things called WIMPs.
05:46No, not that kind of WIMPs.
05:47I mean, weakly interacting massive particles.
05:50These aren't actually confirmed particles.
05:53It's just something that scientists made up
05:55to potentially explain dark matter.
05:57At first, they thought that they should be heavier than regular particles.
06:00Which makes sense, because it should add extra weight, right?
06:04Having mass would make them exert a gravitational force.
06:07Their interactions would still be very weak, as their name suggests.
06:11But still.
06:12They also thought that WIMPs were probably produced
06:14in just the right quantities during the Big Bang.
06:18So they tried to detect them bumping into regular matter,
06:21often placing the detectors incredibly deep underground
06:24so that those annoying cosmic rays don't mess things up.
06:27But after 40 years of research, they found nothing.
06:32And that's when they realized that dark matter particles
06:34are probably not heavier, but the other way around.
06:38Much lighter than any other.
06:40Also, now they think that dark matter might consist
06:43not of one type, but many types of particles,
06:46just like our regular world.
06:48For example, light and ultralight dark matter.
06:52So all this gave them yet another crazy idea.
06:56Exotic black holes.
06:57Imagine that right after the Big Bang,
07:00the universe might have created
07:01a gazillion tiny black holes with unique properties.
07:05The regular ones are born when massive stars
07:08come to the end of their lives and collapse in on themselves.
07:12When they do that, they create a super-dense region,
07:15an unbelievably strong gravity pocket.
07:18You can kind of picture it like throwing a very heavy
07:20and small ball on a super-elastic stretchy fabric.
07:24So it's not really a hole.
07:26It's more like a very deep pit.
07:28If anything comes close to this place,
07:30it instantly falls in there, and climbing back is hard.
07:34Not even light can run away from there,
07:37which is why they look pitch black.
07:39But that requires stars.
07:42However, our exotic primordial black holes were born way before the stars.
07:47They were created in the first quintillionth of a second after the Big Bang.
07:52They've measured this.
07:53They'd be much smaller than all the ones we know today,
07:56and they would spread all across the universe instantly.
07:59They'd still be crazy dense, though,
08:01having the mass of an asteroid in a space as small as an atom.
08:05So, Stephen Hawking thought,
08:07could these guys have created dark matter?
08:11Basically, these supercharged black holes
08:13were born at the same time as our universe,
08:16created a new form of matter, dark matter,
08:18and then evaporated right away.
08:21Pretty insane, huh?
08:23And even though these short-lived black holes might not exist today,
08:26we could still detect their effects on cosmic history.
08:30In any case,
08:31that's just another mystery for scientists to solve.
08:34Let's hope that all these new theories
08:35will help them finally confirm
08:37that dark matter actually exists.
08:39Does it matter?
08:40Yeah.
08:42That's it for today.
