Astronomers Might've Found a White Hole

[Music] the existence of black holes was predicted over a century ago with nothing but math equations now we've taken the first photo of one but black holes still hold plenty of secrets like they're even more mysterious mirror twins white holes really imagine if we could record a black hole on video watch it pull in and consume any matter that gets too close even light itself now take this recording and play it backwards this is what a white hole should be the black hole's pushing away and matter spewing counterpart we'll bring it back down to earth go to your kitchen sink turn on the faucet and see how water flows down into the drain this drain is a black hole it's attraction is too powerful for a stream of water to escape but now focus on the stream itself where it meets the surface of the sink it bursts in all directions with such power that the water can't flow back this is what a white hole should be if you could blast off into space in a rocket you'd meet the biggest challenge the Earth's gravity won't let you go except if your engines are extremely powerful and you're going fast enough to reach what's called escape velocity the black hole's gravity is so immense that escape velocity becomes completely unreachable it's higher than the speed of light and nothing in the universe can go faster than that take this force of gravity and switch the direction now it pushes out instead of pulling in just like it can't escape a black hole's power light can't get close to a white hole that's odd because a white hole has mass so it should have gravity like any space object white hole should attract other matter to them just like the Sun keeps the planets floating around it or the earth keeps your feet on the ground a black hole has outer borders called event horizons within them gravity is the most powerful if something goes beyond this limit it won't ever escape a white hole's event horizon would be an impenetrable border not letting anything inside a black hole is constantly feeding on the matter around it huge clouds of gas and dust that don't get pulled into the hole end up swirling around it they form a luminous accretion disk flattened like that because it's spinning so fast unlike black holes they're white twins probably don't rotate so they wouldn't have these halo like disks there's no evidence that white holes as we imagine them actually lurk somewhere in the universe so far they're purely a mathematical theory plus a massive object constantly spewing matter would have to be noticeable yet they're nowhere to be found but there are theories of what a white hole could be remember learning in school matter cannot be created or destroyed it means the total amount of mass and energy in the universe is constant for example when you burn a log everything in the end the soot ashes and gases will equal the materials put into it and no matter what happens to some particle it still contains information about its original state now this doesn't sit well with black holes scientists know that all the mass they have evaporates with time because black holes leak energy but even if a black hole lost all its mass it still won't give back the information about everything it consumed where does all that material go we're used to thinking that the source of a black hole might be a singularity in its center this is a single point so small yet so massive and dense that physics and math just break down it's almost like it tears a hole in reality itself some astronomers think that instead of a singularity as a dense object in the center there must be an opening deep inside the black hole it might lead to another point in the universe or to a different universe entirely and what could be on that other end is a white hole this would solve the problem with information it simply goes somewhere else entirely instead of just disappearing another idea says that a Whitehall may be a brief period of a black holes lifecycle it's ending if black holes steadily lose their mass they must eventually lose it all and disappear but in this last stage of their life they might become white halls this would explain why we can't detect them since it's almost impossible to find an evaporated black hole their evaporation simply takes too long we know how black holes appear a star much bigger than the Sun reaches an age when its own gravity makes it collapse in on itself in a supernova burst it's much harder to understand how a white hole would form unless it's also the result of aging but of a black hole instead of a star the first black holes in the history of the universe formed soon after the Big Bang happened and those ancient things are great candidates to bring about white holes this idea also makes astronomers think that white holes might be teeny-tiny smaller than the wavelength of light and those are the size of bacteria this would make them invisible to us nothing would react with them because of their repelling force and still they'd have a certain mass in other words they'd be good candidates as the mysterious dark matter it makes up 85% of the universe yet we can't observe it some say the Big Bang itself is suspiciously similar to what a white hole should be a tiny dot that suddenly bursts out and spreads in all directions producing all the matter that will one day become stars galaxies planets and life in 2006 a NASA satellite caught an extremely powerful gamma-ray burst those are the most luminous energetic explosions known in the universe but this one didn't come from an area of space where such bursts are expected his properties were also unusual for both gamma-ray bursts coming from supernova and neutron stars merging while other bursts last just a few seconds this one went on for a minute and a half one of the ideas about its origins just that astronomers observed a real white hole still the most probable answer to the mystery of white holes is that our calculations and predictions about the nature of the universe aren't precise enough in this case white holes are just mathematical models that are cool to play with and think about one thing is certain some 50 years ago black holes only existed on paper maybe white holes will surprise us in the future too
