  • A black hole is a celestial whirlpool of gravitational death.
  • Things can go in, but they can't get out.
  • But it turns out that one of the most powerful things in the Universe could have a mysterious twin, a white hole.
  • Yeah, this beast isn't exactly like a black hole.
  • Black holes are incredibly dense objects that squeeze all the matter they ingest into an infinitely small point at their center, a singularity.
  • Most black holes are remnants of massive collapsed stars, so they have a lot of mass condensed into that point.
  • And a lot of mass means a lot of gravity.
  • Every black hole has an event horizon.
  • This is the boundary surrounding them that marks the point of no return.
  • To escape from the event horizon, you'd need to be able to travel faster than the speed of light.
  • White holes are the opposite.
  • In the same way that nothing can leave a black hole, nothing can enter a white one.
  • That's why scientists theorize that white holes might be the other side of a black hole.
  • Rather than consuming matter, a white hole constantly ejects it into the Universe.
  • If not back into our Universe, it could be a gateway to another.
  • Now, while we've observed and even captured an image of a black hole, we've never seen a trace of one of its white twins.
  • But scientists may have finally found the evidence they've been looking for, mysterious gamma rays showing up where they shouldn't be.
  • Gamma ray bursts are short-lived bursts of gamma ray light that last from a fraction of a second to a few minutes.
  • And in this short time, they eject as much energy as our Sun does over its entire lifetime.
  • Gamma ray bursts are the most energetic events in the Universe.
  • They could be hundreds of times brighter than a supernova.
  • And they happen when a black hole is born.
  • But scientists found one very unusual gamma ray burst.
  • It seemed to appear out of nowhere, only to collapse on itself very quickly.
  • And even though it lasted about 100 seconds, it behaved like a much shorter burst.
  • This particular gamma ray burst, called GRB 060614, didn't have the usual afterglow that comes from a black hole.
  • And that's why scientists think this might be the proof we needed of a white hole.
  • So it's time to check it out firsthand.

  • This trip to the white hole is going to be costly.
  • If you traveled across the Universe to catch a glimpse of this theoretical white hole, what you'd find would look like a black hole, a dark emptiness, a ring of dust and gas separated by an event horizon.
  • But you wouldn't slide into the center of the singularity.
  • No, instead, things would get rough.
  • Your spaceship would be blasted by intense gamma rays, destroying it and everything inside.
  • Now, even if you could survive that with the help of super-advanced gamma-protective technology that doesn't exist yet, you'd still never be able to enter the event horizon of this white hole.
  • It would be like immense air resistance back here on Earth.
  • The ejected radiation would constantly slow you down.
  • Add to that the challenge of moving through space-time that's being warped around you, and it would almost be like you were traveling uphill with an extreme wind blowing you away.
  • You'd need more energy to overcome this resistance and push forward.
  • And the closer to the white hole you get, the more energy you'd require.
  • There would come a point where you'd need more energy than there is in the entire Universe.
  • But there might be another way in.
  • If a white hole truly is the backside of a black hole, then traveling into its singularity would be like going through a black hole in reverse.
  • But now, not only would you be competing against the powerful forces of gamma radiation, but you'd also need to overcome the impossibly powerful forces of gravity working against you.
  • Oh, and you'd need to travel faster than the speed of light.
  • Of course, that's impossible.
  • Nothing can travel faster than light.
  • But you might be able to get to your destination by jumping into a black hole first.
  • Scientists think that there might be a wormhole connecting the white hole to its black hole companion.
  • This could be your only way in.
  • Except this passage would be extremely unstable.
  • The entire thing could collapse unpredictably at any moment.
  • I doubt you'd want to be inside when that goes down.
  • Don't say I didn't warn you.
  • If you were brave enough to jump into a black hole, you'd have to pass its event horizon.
  • Once you were inside, you'd see another energetic burst of bright light.
  • After this, the black hole would seem to expand all around you, surrounded by a ring of light.
  • You'd be feeling pretty disoriented by now.
  • It might almost appear as if you were free-falling back through the black hole.
  • This wouldn't be the case.
  • This is just an optical illusion known as relativistic beaming.
  • And of course, this wouldn't be the only extreme effect you'd experience.
  • You'd still need to do the impossible, and somehow break the cosmic speed record.
  • Traveling faster than the speed of light, you'd be overcoming the most extreme forces of gravity pulling at you from behind.
  • And because of that, your entire body would be stretched out very thin.
  • This would be reverse spaghettification.
  • And finally, the disorienting effects of the relativistic beaming would make it appear to shrink ahead of you, like you're getting further and further away.
  • But eventually, you'd overcome all that gravity and blast your way out of the event horizon.
  • And now, you'd be spewed out the other side of the black hole, into a completely different part of our Universe.
  • Or maybe not even in our Universe at all.
  • Yeah, come on, you just traveled through a black hole and then a white hole.
  • Anything's possible.
  • 13.8 billion years ago, all the matter and radiation that makes up our Universe emerged out of a singularity.
  • Maybe you just traveled through the black hole that created our Universe.
  • It sounds like you've got another epic journey of discovery ahead of you.
  • But it might not be as easy as you think.
  • It's possible you've entered a Universe with entirely different laws of physics than the ones we know of.
  • You might be better off checking out something else that scientists have discovered.
  • Like this terrifying planet that looks like Earth.
  • But that's a story for another WHAT IF.
