00:00A giant wormhole, or simply said, a connection between regions of space-time, opens up in space near Earth.
00:07Our world faces chaos unlike anything before.
00:11Satellites incinerated, skies ripped open by radiation storms, entire power grids blacked out.
00:18The atmosphere is swelling and scorching, the oceans are boiling, the magnetic shield is shattering.
00:24Suddenly, the wormhole destabilizes.
00:27Space-time starts to unravel, tearing Earth apart from the inside out.
00:32People are seeking shelter, but nothing can save them anymore.
00:36Look at this devastation.
00:38This isn't just a sci-fi scenario.
00:40It's a cosmic apocalypse waiting to happen and rewrite the fate of humanity.
00:45The thing is, some black holes might actually be secret space portals.
00:50It may sound like something straight out of Stranger Things, but it's not.
00:54Scientists have been wondering for years if some black holes could actually be wormholes in disguise.
01:00Tunnels, through space and time.
01:03And now, a new study says this might actually be possible.
01:08At least in theory.
01:10Wormholes are like cosmic shortcuts that let you pop out in a totally different part of the universe.
01:15Unfortunately, we've never found one, and the whole concept still lives in the land of what-if.
01:22Here's the problem.
01:23To actually make a wormhole work, you'd need something called negative energy.
01:28That's not just rare.
01:29It doesn't even exist in the regular universe.
01:32Maybe in some weird world of quantum physics, but even there, it's super uncertain.
01:38Still, scientists have a wild thought.
01:40What if some black holes aren't just giant space vacuums that swallow everything around them, but are really hidden wormholes?
01:49The odds of that are tiny, like winning the lottery while getting struck by lightning and discovering extraterrestrials at the same time.
01:56But mathematically?
01:58Mathematically, it's not impossible.
01:59That's where the new study comes in.
02:03Researchers looked at a weird type of black hole called a Schwarzschild black hole.
02:08These ones don't spin, don't have electric charge, and, very predictably, are totally hypothetical.
02:15They're just the math version of a black hole, not something we've seen in space.
02:20In any case, the team studied something called quasi-normal modes,
02:23which is just a fancy way of saying how space vibrates around a black hole when you mess with it.
02:30These vibrations don't go on forever.
02:32They fade out like the ringing sound you get when you hit a bell.
02:36By analyzing those space-time vibes,
02:39scientists tried to figure out if they could tell the difference between a regular black hole and a wormhole pretending to be one.
02:46It turns out that it's super hard to tell this difference.
02:49But maybe that's the point.
02:51Wormholes might be hiding in plain sight, wearing black hole costumes like it's Space Halloween.
02:58Wormholes could copy a black hole's behavior almost perfectly, at least on paper.
03:03The researchers uploaded the whole study to ARCZIP,
03:06which is where science nerds drop their ideas before they hit the big journals.
03:10And it's already been published in Physical Review D, which is a serious physics magazine.
03:16The coolest thing, though, is that it isn't a brand new idea.
03:19Scientists have been debating this whole black hole or wormhole thing for decades.
03:25Back in 2021, some researchers wondered if the giant black holes at the centers of galaxies,
03:30called active galactic nuclei, were actually wormhole entrances.
03:35And in 2022, a team in Bulgaria said that the light coming from a wormhole could look almost exactly like what comes from a black hole.
03:43There's also this sci-fi-level theory that some black holes might be paired with opposite twins, called white holes.
03:52A white hole basically spits stuff out instead of sucking it in.
03:57Together, a black and a white hole could form a wormhole tunnel.
04:00But no one's found a white hole either yet, so that idea is still just theory.
04:07By the way, in this latest study, the authors have shown that wormholes and black holes not only look similar, but also sound similar.
04:17At least in how space-time shakes around them when they get hit with something.
04:20So our next move should be fine-tuning our scientific models, especially near the part of the wormhole called the throat.
04:30Scientists want to see if wormholes could fake even more black hole-like behavior, but it's tricky.
04:36Some of the math gets super hard.
04:38In any case, how about finding out more about these mysterious wormholes?
04:43You've seen them in every second sci-fi movie.
04:46Magical space tunnels that let you skip across the universe.
04:50Einstein was the first one to have dreamed them up.
04:53Wormholes are still 100% hypothetical, and we've never spotted one.
04:58But that doesn't stop people from theorizing.
05:00Like, what if a wormhole started sucking in matter like a black hole does?
05:05If a wormhole started eating stuff like dust, gas, or space debris,
05:09it would create a plasma tornado, a literal space firestorm in its throat.
05:15And this twisty storm would eventually blast out the other side of the wormhole,
05:20firing hot plasma at nearly 125 million miles per hour.
05:25That's about one-fifth the speed of light.
05:27It would also be insanely hot in there.
05:30So hot, it could probably trigger nuclear fusion.
05:33Of course, all of this is still just theoretical.
05:37No one's seen a wormhole do this.
05:39No one's seen a wormhole do anything, actually.
05:43But the math says it could happen, if we ever find a wormhole.
05:48The bright side of it all is that we would probably spot an event with so much drama.
05:53Even though wormholes don't have an event horizon,
05:56aka the point of no return, like black holes,
05:59they still bend light.
06:01Normally, you might not be able to see something like that,
06:03but this thing is so absurdly bright from the plasma firestorm
06:07that you would actually see it glowing in space.
06:11Think of it like a black hole, but with a glowing center instead of just darkness,
06:15and a jet of flaming plasma shooting out one side like a broken space faucet.
06:21Still, don't get your hopes up for spotting one anytime soon.
06:24Even if we did find a wormhole, it probably wouldn't last long.
06:29It could break apart or transform into a completely different type of space-time
06:33before we even realized what we were looking at.
06:36Plus, keep in mind that wormholes might look almost exactly like black holes,
06:41unless you know what kind of light polarization,
06:44how light waves line up, to look for.
06:47Now, let's talk a bit more about black holes themselves.
06:52You're likely to know them as insane space beasts that suck up everything nearby,
06:57gas, dust, even light.
06:59And once something crosses a black hole's event horizon, it's trapped forever.
07:04Scientists say that inside, everything gets crushed into a tiny point called a singularity,
07:10where the usual rules of physics totally break down.
07:13But back in 2010, a physicist named Nikodin Poblovsky had a crazy idea.
07:21What if black holes don't have singularities?
07:24Instead, what if the center of a black hole is actually a doorway to another universe?
07:30Maybe our entire universe was born from matter shooting out of a black hole in some parent universe.
07:36Poplovsky's theory uses something called torsion,
07:39which is like a weird gravitational twist that stops matter from getting crushed infinitely.
07:45Because of torsion, instead of crashing into a singularity,
07:48matter inside a black hole can create a tunnel,
07:51a so-called Einstein-Rosen bridge,
07:54or simply, a wormhole,
07:56connecting a black hole to a white hole.
08:00So, imagine matter falling into a black hole in one universe,
08:04then popping out of a white hole in another.
08:06Poplovsky thinks this could explain the Big Bang,
08:09but as a big bounce,
08:12meaning the universe keeps cycling through phases of expansion and contraction,
08:16not just one huge explosion.
08:19Sadly, if such a tunnel existed, it would be a one-way trip.
08:23Nothing would come back through to the original universe.
08:26Some scientists are still skeptical,
08:28because torsion hasn't been proven yet.
08:31But other experts think Poplovsky's model is super promising.
08:34They even go further and say that our whole universe
08:37might be living inside a giant black hole
08:40hundreds of billions of light-years wide.
08:43Now, we just need to figure out how to test this.
08:47Future space studies might give us more clues,
08:50like checking if our universe is closed,
08:53which basically means that it's curved, without an edge,
08:56or digging deeper into cosmic background radiation,
09:00which is the leftover glow from the Big Bang.
09:03That's it for today.
