White Holes: An Impossible Possibility

White Holes: An Impossible Possibility

Okay, let me get this out of the way: white
holes are almost definitely not a real thing that can be found in nature. So keep that in mind when I say…we might
have seen one? (INTRO) In theory, white holes are black holes that
are going backwards. In theory. A black hole, as you know, is a giant object
that sucks stuff into a singularity – a single point of infinite density – from which there
is no escape. So a white hole would be an object that expels
matter from a singularity…and you’d never be able to enter it. White holes only exist in math. But in 2006,
we saw an explosion of light out in deep space that we can’t explain any other way. It’s…even weirder than it sounds. In reality, a white hole would violate the
second law of thermodynamics. This says that the amount of entropy in the universe can
only stay the same or increase. It can never decrease. Entropy is often described as disorder, but
it’s more like a measure of how many different states that particles in a system can be in
at any given moment. Like, if you have a piano, and you throw it
in a woodchipper, you’ve increased the entropy of the piano. Because a pile of chopped-up
piano splinters can be in lots and lots of different configurations while still being…a
pile of splinters. But these piano splinters can really only
be in one, very specific state in order to be a piano. At least … a piano that works. So, black holes are great at increasing entropy!
They’re the universe’s woodchippers: shredding entire stars into pulp, and leaving only a
whiff of radiation. But you can’t load your pile of piano splinters
into the woodchipper, and run the thing backwards to get a piano again. That would decrease
entropy, which is not allowed. And if white holes existed, that’s essentially what they’d
do. So why does anyone think white holes might
exist in the first place? Well, they were first proposed as a kind of
mathematical oddity, because of Einstein’s theories of relativity. One of the many endearing quirks of relativity
is that it doesn’t care whether you play time backward or forward. If time can go in one
direction, it can just as easily go in the other. So if black holes are a thing, then white
holes – which are black holes played backward – can also be a thing. But just because relativity says time can
go in both directions, in practice it pretty much sticks to one, as we all know. So even if a white hole did somehow occur,
it would be incredibly unstable. Because the universe DOES NOT LIKE IT when you break the
laws of physics! So a real white hole would probably only last for a few seconds before
it collapsed in on itself to become a black hole. Which brings us back to the explosion we saw
in 2006. Detected by NASA’s Swift satellite on June
14, it was a huge gamma ray burst: the highest-energy type of explosion possible, a million trillion
times more energetic than the Sun. And it lasted for…102 seconds. Scientists believe that gamma ray bursts only
last that long during supernovas. But this one, labeled GRB 060614, didn’t have a supernova
to go with it. As far as we can tell, it was an explosion
of white hot light that came from nowhere, and then vanished. And while white holes remain incredibly, stupendously,
ridiculously unlikely…that’s pretty much exactly what we think one would look like. Some physicists have offered other explanations
for what it might’ve been — like a shock wave from neutron star torn apart by a black
hole, or maybe two neutron stars colliding. But events like these only release energy
for two seconds at most — not a minute and a half. So. White holes in nature are as impossible
as a thing can be, while still being technically possible. But they are technically possible. And until
we see another explosion like the one in 2006 that we could hopefully learn more from, we’ll
just have to wait, and wonder. Thanks for watching this episode of SciShow

  1. So what is it? I've never seen one before, no one has, but I'm guessing it's a white hole. A white hole? For every action there is an equal and opposite reaction. A black hole sucks time and matter out of the universe, a white hole returns it. Is that thing spewing time back into the universe? Precisely. That's why we're experiencing these curious time phenomena on board. What time phenomena? Like just then when time repeated itself. Hey, wait a minute, I missed a discussion. We all did. Time is occurring in random pockets the laws of causality no longer apply, an action no longer leads to a consequence. Since we're no longer affected by the laws of causality, we can override these time jumps if we concentrate. Look the only way out of this is to consult Holly. I'll go with that. Get's my vote. So it's decided then, we consult Holly. Ah, I think we just encountered the middle of this conversation. So what is it? I think we've experienced this period of time before sir. Only joking. And that one. Oh, someone punch him out! She only has two minutes left, perhaps I should talk to her. Leave this to me Private. On! Whiteholespewingtimeenginesdeadairsupplylowadviseplease. Excuse me? Whiteholespewingtime-

  2. The universe is one big black hole generator and each black hole creates a white hole or a big bang on the other side and thus the multiverse.

  3. You're missing the whole point…Black holes and white holes are like connections between universes. White holes do not exist in our universe. They are the big bangs which start new universes. Black holes and white holes are two sides of the same coin. A black hole in another universe led to the white hole (big bang) that started our universe.

  4. as the 2nd law of thermodynamics is a statistical law it's not impossible for localized events to run entropy backwards: see Boltzmann brains

  5. So wouldn’t it make sense if you went into a black hole and then you’d come out of the white hole because you can go in a white on and you ant get out of the black one.

  6. Maybe after some time of matter entering a singularity, all the matter that entered it would be expellled (this is based off of the theory that the universe expands then contracts then expands).

  7. Theoretically, the black hole is an infinately dense within the space-time continuum; thus, a white hole is like a reverse vacuum releasing the broken matter taken in by the aforementioned black hole.
    If this is so, then how are they connected to one another in two different locations or dimensions?

  8. But dont black holes also break the law of conservation of energy? It cant take in light and destroy it so it has to go somewhere

  9. Not sure about some of the assertions here. White holes wouldnt be expected to split out stars and star systems for instance. Not exactly the reverse of a black hole.

  10. Your so called law of entropy is wrong, it has been well established that the law of etropy does NOT hold on the universe as a whole, through out all time….I.e. say we have a box with all the air pushed to one side and are randomly moving around, this is a representation of high entropy, and yes over a given time all the particles will "evenly" space themselves out, lowering the entropy, but the laws that govern random possibility, dictate given enough time (some say longer then the age of the universe so far) these random particles WILL ,EVENTUALLY clump back up in there original position, Just as Newtonian physics is an approximation to relativity, the law of entropy is an approximation , taken over a finite time interval .
    2nd) the law of Entropy is only valid if there is NO NEW ENERGY introduced to the system, but we know know that the universe is NOT a closed system, the introduction of expanded space showed us this in the early 90's.
    I know it is well taught , that every thing is heading to a stand still. it is some times easier to treat the general public like morons, then to explain to them how they got it in correct

  11. So… In the big bang theory it is stated that there was nothing until an explosion cam and now there's everything. Maybe a black hole separates hydrogen and helium together through spaggetification in which something can consume something that is bigger than them. If the black hole became "full" after it "ate" all of the galactic bodies, it's gonna explode and the big bang theory will occur again.

  12. What if, when a black hole gets big enough, it becomes unstable and shift direction? It would briefly become a “white hole” and then disappear from existence.

  13. Maybe I haven't fully grasped the concept of white holes or the 'wooder chipper analogy', but using that analogy; I get that when reversed a whole piano cannot come out a wood chipper, same as a planet/star being spat out a white hole would not come out as a planet/star because it breaks down the laws of physics. However, when you feed a piano into a wood chipper, you get wood chips. Therefore, a white hole would not spit out a planet/star, or the metaphoric piano, butit would surely just shoot out the mbroken down matter that it absorbed, right? That wouldn't be the same as 'a whole piano' but would be the same as the wood chips.
    The matter has to go somewhere. Information cannot be destroyed, 'infinity' cannot mathematically exist and what little does escape black holes is considerably less than goes in. Lumination and heat aside, which has to be significantly smaller than the energy put it, the information must go somewhere…

  14. does water freezing, smashing into separate ice chunks, then melting into one pool not break the rule that entropy can only be increased?

  15. Einstein did not have access to a complete standard model
    when he theorised black hole singularities. Einstein had no knowledge of Dark
    Energy. In theory, a black hole crushes matter to a singularity. Lesser gravity
    produces neutron stars, containing neutrons (The protons and electrons turn
    into neutrons).In addition there are Quark stars or Boson stars. The issue is
    that gravity relates to subatomic particles differently.

    The standard model constructs a basic hydrogen nucleus out
    of one proton. A proton consists of two Up Quarks and one Down Quark. Gluons join
    the Quarks. 95% of the energy of the atom is contained in the binding force
    from the Gluons. Under E=MC^2 we know mass equates to energy. However, subatomic
    particles interact with the Higgs field differently. The Higgs field
    interactions by subatomic particles influence mass and corresponding gravity.

    In a collapsing star, there is a struggle between the outward
    pressure forces of the atom and the crushing force of gravity. Gravity causes
    the atomic nuclei to combine, through fusion, into larger nuclei.  The star eventually collapses into a neutron star.

    The step beyond the neutron star is a disassembly of the nucleus into
    subatomic particles. However, most of the energy of the atomic nucleus is in
    the binding energy of the Gluon Bosons between the Up and Down Quarks. When
    gravity breaks the Gluon bonds, the energy dissipates into particles that are harder
    for gravity to hold, photons, neutrinos and other WIMPS cause the overall energy
    of the black hole to dissipate through dark energy /matter. The reduction of black
    hole energy prevents a collapse into a total singularity leading to the black
    hole turning white and irradiating away.

  16. Yea good video and explanation.
    Apart from that, am I the only introvert here who gets unsettled and genuinely annoyed by this guy’s (apparently) intentionally overly exaggerated gestures and tone that don’t seem to come out naturally?

  17. Black holes do NOT suck anything in. Stop saying that. People think it's a giant vacuum. It's not. It's extreme gravity.

  18. If a white hole is connected to a black hole via an Einstein-Rosen bridge then the decrease of entropy by the white hole is counteracted by the increase in entropy in the black hole, even if the stuff entering the black hole ends up in another universe. That way the conservation of matter and information is also maintained.

  19. 2:54 Don't agree that it needs to last longer or that it is unrealistic to have White Holes, unless you believe that the mass goes to infinity(general relativity's singularity).
    My hypothesis(based on quantum theory of gravity) is that after black holes merge a number of times(or not), the compression of mater reaches a maximal point, at which point there is a quantum bounce and all that Energy is released in the opposite direction, thus you have the "Big Bang" effect.

  20. I think that the big bang is a white hole that transported space time here to this dimension. My theory.

  21. If black holes exist then white holes exist. From what I gather the two look the same in space. For all we know we are looking at white holes and do not realize it.

  22. Yeah but if it gets chucked out as pure light energy many light years away or as a blow out in space time that could be how a big bang happens the cycle we need to explain us…

  23. Like anti matter maybe we cant see or detect certain types of matter that our that opposite us..like a third charge positive negative and a third type unknown to us no mass or anything in our world and we cant sense it yet a world of spirits and other forces for example.

  24. I think I figured out enstine theory, space wormhole systematically it will work, ok so Jupiters moon natural elements and mercury elements the white space matter, GPS passageway, a room size of people, white matter pushes everything away making a clear passage for place to destination, gravity x white matter clear passage, , planet relocation quick , so planet to moon one stop shop we send a room to room, send everything over there and wormhole there , instant time? Signal to signal destination to destination

  25. White Holes CAN exist. Just not in the way currently modeled. Which means your model is wrong and so is your analogy. First they would not be persistent. They would " flicker " randomly both time and space. Second they would be a quantum object. Not perceptible with any technology we have. Finally, they would be the end of the chipper so to speak. As in they would be expelling a chip of material collected inside a black hole and then vanish immediately afterwards.
    I suspect this is part of the source of dark energy. And the result is a expansion of space/time in the voids of interstellar(? spelling) space. If this is correct it would not violate any laws of physics, but would help explain why the visible universe is shrinking while the actual universe is expanding.

  26. It is simple, our understanding of science is flawed. For example, entropy in itself can decrease. Black holes are a great example of universe naturally decreasing its entropy. Gravity itself is a natural law of existence which decreases entropy itself. If it takes me few seconds to point out inconsistencies in modern science, it is no wonder that our theories and hypothesies are being broken seemingly every day with new discoveries and scientists are in full fantasy land talking about imaginary things like dark energy and matter about which they have no clue about.

  27. “You can’t feed a pile of splinters into a wood chipper and run the thing backwards to get a piano again.”
    Challenge accepted.

  28. A white hole is easily explainable, it is essentially a black hole that has collapsed in on itself with such voracity that that it has turned inside out. The white hole only exists for such a limited amount of time as the energy caused by the output causes it to flip back in on itself causing another black hole.


  29. Are white holes really that much of a stretch though, in reality? Because by the laws of physics, black holes shouldn’t be able to function the way they do. Since we on earth have definite laws that are constantly proven, we for a long time, had no way of knowing if there are things or objects that defy those rules. But if we are going to assume that the law stating that ‘matter cannot be created or destroyed, only transformed’ is definite and can’t be defied, then wouldn’t it actually make even more sense for a white hole to exist? According to y’all, when something is torn apart it increases entropy. Well, what if white holes didn’t decrease entropy, but instead maintained it? What if the two were somehow connected, possibly via a wormhole, and they worked together kind of like the recyclers of the universe? Black holes break down matter to its most basic forms, and white holes spit the broken down atoms and molecules back out somewhere else in the universe for them to be transformed and changed into a new planet or star or whatever they’ll become. Then that would mean that the sudden bursts of light we see is whatever light entered the black hole. And what if one or more black holes were connected to more than one white hole at the same time? Not being able to see a white hole shouldn’t be a reason to assume that they don’t exist. After all, didn’t we just recently get the very first picture of a black hole?

  30. If white holes exist and they are the opposite of blackholes and some people believe that blackholes are wormholes. Couldn't whiteholes be the exit ofthe said wormhole
