There are a few possible explanations.
1) We misunderstand thermodynamics. All it takes is a single valid counter-example to completely destroy a scientific theory. It could be entirely possible that entropy *can* decrease under certain circumstances. The Big Bang theory, in fact, relies on this.
2) The entire universe is not an isolated system and the extra energy is coming from some greater source which our universe is a part of.
3) Black holes represent a point where the curvature of space-time becomes infinite; an asymptotic function. A White hole would just be infinite curvature from the other way. Think of the graph of a tangent; it drops down to negative infinity only to re-emerge across the asymptote from positive infinity. The "singularity" of a white hole would need to have negative mass and generate a counter-gravitational force. It would also cause time to speed up around it.
Remember, the universe is what it is. We formulate theories and laws to describe and explain and predict, but the universe isn't beholden to behave the way we think it should. Reality trumps science. If something happens that breaks the laws of physics, it means that our understanding of physics was wrong, not the reality. And the universe won't give a damn.
Maybe a white hole is simply where a black hole reaches a maximum real density per area, where it then emits matter and energy until it passes below the maximum threshold which at that point it returns to being a black hole .
bro your smart
Omar Goodman Very wise observation 👍
wouldnt negative be the same thing as anti matter
reference the thunder bolts channel for a comprehensive population on how everything more or less the main scientific community is clinging to is invalid.
I don't understand that wood chipper analogy you used to explain entropy. if a black hole is increasing entropy by shredding something up and sucking it in, isn't a white hole simply throwing those wood chips out again? how does that decrease anything? you made it sound like a black hole would shred a star and a white hole would throw out that star exactly how it was before it was shredded...
Thats interesting alright I don't understand this "woodchipper" analogy either...
Well, say this was a really powerful woodchipper that _atomized_ the piano, a white hole would be the equivalent of it spitting out woodchips. Not a whole piano, but definitely a lot more structured than a bunch of atoms. The stuff coming out of a white hole, while not an exact replica of the star that fell in, would be possibly atoms, maybe just subatomic particles, but anything is less entropic than matter in the center of a black hole, even if it is a bunch of atoms and particles.
the wood chipper analogy is to show that matter can be returned to the universe through a white hole, much like wood is returned out the exit port. Black holes are thought to irreversibly pull matter in, but it is a possibility that matter is also spit out through a white hole.
It won't come the same way it was pulled in, of course. But the matter itself won't just disappear as it's vacuumed up, it's just moved. A baseball thrown in won't be a baseball coming out, but the mater it was composed of will come out if white holes exist.
I believe that what he means with the woodchip analogy is that if you run a woodchipper backwards. it won't spit out a piano. But if you run it backwards in time it will then spit out a piano and thus decrease entropy (Like playing a video in reverse). So essentially a white hole is a black hole running backwards in time. And the reason we don't see a star or a planet shoot out whole, is because the whole system is unstable and collapses before that can happen.
joe kickass The answer is, he doesn't know what he's talking about. He's parroting bits and pieces of things he's heard from other people and botching it all up in the process. I was just saying in an a la carte comment, a white hole is NOT a time-reversed black hole, time reverse a black hole and it's still a black hole.
maybe when you go into a black hole you get broken down into your base components and are shot out as space glitter in another universe
+Paradox xodarap Space Glitter? That's brilliant! :P
Exactly. When I die I'm aiming to get my body shot into a spiral black hole so that if I come out on the other side then I might be with more intelligent life that could start my heart beating again.
Gracc Mcdede
what method of propulsion will you use
advanced technology in the future will get me there also maybe we could put a tracer in to see if it reassembles or something
+Paradox xodarap It's not impossible.
Reid has such a great presentation voice. It would be impossible to fall asleep in a class taught by him.
You would probably fall asleep once he started discussing the math involved. I know I would.
It was some aliens mixtape, lit af
Ayy
lamo
Oh shit waddup
lmaooooo
I say it was a gigantic alien explosive used during a war. And I base that entirely on nothing.
The total entropy of any given *isolated* system cannot decrease. The existence and organization of life is a decrease in entropy - but, in total, the entropy of the earth can only increase. The only truly isolated system is the entire universe, as long as the total entropy of the universe does not decrease, why do white holes violate the laws of thermodynamics?
Actually the Universe itself increases in entropy but smaller systems like Earth can decrease in entropy from outside forces
Exactly my point. So why couldn't a white hole decrease entropy of the space around it, at the cost of having the rest of the universe compensate for it?
+RainingArtillery I'm not 100% on this but I think it's because that there isn't anything in the Universe compensating for the extra matter that is entering the Universe. I think a good example would be Quantum Fluctuations, in this there are pairs of anti and matter particles that enter the universe and annihilate which is allowed to happen based on the Uncertainty Principal of Quantum Mechanics but annihilate to cancel out the matter that was created, plus when these particle-anti particle pairs are in a black hole(one on the outside an the other on the inside) one escapes and turns into a real particle( or anti particle) and the other falls into the blackhole. Since extra matter entered the Universe the Black hole should lose mass to compensate for extra matter. So my point is that white holes would indeed inject extra matter into the Universe but the White Hole wouldn't lose mass because it isn't made of the material in this Universe it just transfers material from another.
+Avinash Reji I agree correct.the blackhole is more physical than the white hole but blackholes are a possible impossibility and has mostly infinit volume. 0 volume.and white holes decrease entropy an also is a singularity but with its own twist.white holes are also said to have no event horizon.some even go deep enough to say whiteholes are on the other side of blackholes . blackholes are also said to flip to whiteholes. but what I don't agree with is whiteholes flipping to blackholes.i also dont believe nolonger that all blackholes are a dealth sentence because of there extremely gravitational pull or extreme negative force.all black are different to the certain areas of space particular there in.i believe different Ares of space =different impossibly or unknown outcomes.like every 1 says nothing can escape blackholes. when recently they discovered something huge came out the front side of a blackhole. an I also don't believe that all whiteholes are very unstable or could only last for a couple of seconds.false.deep down I believe there are some extremely stable.
How do we know the universe is an isolated system?
The death star blew up
In a galaxy far far away. Lucas is a prophet.
is the death star not to small to see fom so far away?
Depends on how bright the explosion is. We can see explosions in space from stars that blew up before the Earth was even formed because they were so far away.
Adjuni but seeing the dath star blow up. there was not much light that came out with that explosion
No need for much light in the visible spectrum, just the core explosion would have emitted high energy radiation, detectable by satellites with the right equipment, we do this all the time, detecting radiations beyond the spectrum of visible light to find new space entities.
SciShow Space - Would love to see an episode dedicated to my favorite Nebula: Eta Carinae. It is a fascinating nebula from which scientists have learned a lot about the Universe.
Or if that's too little of a topic for a whole episode, I'd be happy with an episode on the Oort cloud (a fascinating enigma of our solar system).
I'm beginning to think there is no such thing as "The Laws of Physics". I think it is more "The Habits of Physics". But what do I know? I'm no physicist and can't tell anyone what's impossible. But so many people who are much smarter and more educated than I, seem to get wildly confused about what they thought was settled science.
+christine hancock Man me too
+christine hancock Laws of Physics are more like this...The Laws of Physics of Earth...Other world/Solar system/Galaxies/Etc. we don't know if they follow the same rule book
+christine hancock the reason that they are called laws of physics is that they are set like rules that can't be broken by any physical(actual) means
Meaning a black hole that stops time probably runs on different higher laws of physics.
cybo adams They are Laws of Physics to the only place we know they are true...We don't know if Laws of Physics are true for other planets
the laws of physics applies to our universe they would be different in other universes and be the same on every planet in our universe
Obligatory sexist, racist, unnecessarily crude comment ahead:
I knew a white hole once. She was very giving in many ways but wouldn't let you stick anything in.
well played... hahaha
This was by far the best analogy for learning about entropy I've ever heard
Why would a White Hole decrease Entropy? It just spits out all the mass inside it. It doesnt't create new matter or creates Less possible states of this Matter than before it just moves them out of the Singularity into space. So I get why a White Hole would be unstable and why it possibly never would occur but I don't get the Entropy part you were talking about^^'
Wouldnt the mass energy coming out be simplified making the information micro states less entropic?
Disclaimer: I’m not a physicist, this is just my layman’s guess.
A system with high entropy is one with low potential energy. The more entropy, the less can happen. Since matter attracts other matter through gravity, a system with blobs matter far apart from eachother has low entropy (due to its high gravitational potential energy). In other words There’s low entropy because the blobs can still get closer to eachother. That’s a thing that can still happen. In a system that’s just a single black hole, nothing can happen. All the matter is already infinitely close and can’t get any closer. A white hole would decrease entropy by allowing stuff to happen again, ie matter to once again proceed to get closer to other matter
It’s like the portal thing - if you put a white hole and linked black hole next to each other, something would go in one and out the other, then again, and again, and again, continually accelerating.
It was the Death Star exploding, the light finally reached us.
Well, if there is really an infinite number of parallel universes than that would have really happened somewhere. :D
Ivars Braze And technically you also got murdered by a midget named Tom the Bomb in one of these universes
FPG
That is exceptionally scary.
The death star explosion was far shorter than 102 seconds, perhaps 5 at the most.
mark slack You must be fun at parties.
Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth.
How if... The big bang was a white hole, which connected from a black hole from another universe which having a big crunch as it meets the end of its life?
Btw, if FTL travel mechanism has been acquired, I believe the white hole described on the video is exactly what happened when a ship coming out from a FTL jump.
Spicy I believe so. Or it's just two different universes which happen to occupy the same space. One is dying, the other one is born as the result of the other which died.
shut up ur scientific talk! god created everything blah blah END.
daniel tajne even God created everything using theories.
daniel tajne so you don't like scientific talk and also don't like spiritual talk? What are you?
Li Yong Chen 1 comment was sarcastic.2 comment was question that blew up ur whole god theory
what if the big bang was a white hole..or the opposite side of a black hole
+Project wow so that means that just like a star is born in the ashes of the old one. a black hole big enough within our universe might be the next big bang and that another universe?
+Project
That is fantasy.
You cannot have a universe inside a black hole.

Ru-Fee-O, Ru-Fee-O, Ru-Fee-O... RUFIOOOOOO
+Roger McKay how do u know its immpossible. have you been in one?
Deez Kaka
Let me know if you have a serious question.
'A single point of infinite density' Impossible. Very, very, VERY, dense, mind you, but nothing can be infinitely dense. If something was infinitely dense, it would require infinite mass, and since gravity is based off of the mass of an object, infinite mass(and inturn, density) would mean that said point would devour the entire universe spontaneously. which, obviously, isnt happening.... so yeah. Not infinite.
Well density has two variables, so you don't need infinite mass, all you need is a volume that tends towards zero. That's why black holes are called singularities.
fattony638 approaching infinitely dense is the same as infinitely dense-or close enough.....there is no true infinite you say? look around you my friend....its easily created with examples: a mirror and an eye and a brain. a video of its own display. 1/3 or a whole number displayed in decimal form. many forms exist--at least our definition of exist....
fattony638 True, but you can't have a volume that is zero whilst still having mass. So, the only way to have infinite density, mathematically, is to have infinite mass.
Exactly, however, not instantly but in the course of 1 plank second
***** The fact is that infinity has a definition, and that is "Something that never stops going" like ex: the amount of decimals between 1 and 2 is infinite, right?, you can count and count, and you will be counting forever and never stop. The the amount of decimals between 2 and 3 is equally large, so the amount of decimals between 1 and 3 is also infinite, you can count and count and never stop, BUT that infinity is twice as large as the two previously mentioned equally large infinities. So infinities can vary in size, however he is right about a black hole not having infinite density and mass.
My mother always says " in this household we obey the laws of physics" I believe this breaks that rule.
What if white holes are the opposite end of a black. What I mean by that is, sense a black hole could theoretically be a wormhole, maybe the white whole is the exit from the black hole, sense they're opposite, like entrance and exit.
Going in a black hole and coming out a white
once you go black......
ok im leaving
its theoretical only to people that dont engage in science. humans can only survive at a maximum of around 8-10 g's. A black hole is basically the hyperdense remnants of a star and it puts all the matter it absorbs into a singularity. matter wont survive being pulverised by a point of infinite density
Yes, it could be true. There is, actually, a theory that says they could be linked by a wormhole. In other words, it says that it is possible that matter enters from a black hole, travels through a wormhole and exits from a white hole. I believe that they could even be linked to each other directly, without a wormhole.
It would have to lead to another universe where physics work differently
If I would send alien neighbours "Hello, im here, im inteligent but don't fuck with me" It would be like grb060614
It could be intelligent extraterrestrial alien activity but there is no scientific claim to that idea.
Unless maybe they are saying "we are here" with them assuming that other intelligent life knows nothing like this can happen naturally. And maybe they are like earth asking "where all the Aliens at doe"
+ryxd100 Good at fermi paradox
Has even tons of more oppurtinites than just the two you just listed
+Sheriff S I was thinking the same thing. The fermi paradox hinges in the idea that we haven't seen any signs of extraterrestrial civilizations yet all we would need in some kind of disturbance or unnatural phenomenon to take place to count as evidence. So far we haven't seen any. This is a strange phenomenon alright but only after we see enough examples to form a better idea can we really determine this as evidence for aliens.
+Sheriff S How to signal life: Make something that is mathematically possible, therefore can be done, But cannot happen under ANY known model of things that happen naturally, like breaking entropy, requiring something fundamentally anomalous (LIKE LIFE) to trigger it.
Belqinor Forelorn
Wouldn't think be considered "breaking entropy"? Isn't that what a white hole is by principle?
So black holes steal and white holes gives
Yep
#blackholesmatter
true
Black holes uphold the laws of physics, white holes break the laws.
+Blue Eyes White Teddy That's a first, Kappa
+Jesus black holes unite things together while white holes break things apart
This host has REALLY improved sense last time I seen him on this channel. Good job!
Technically speaking, Nothing in this universe "violates" any laws. They only violate our laws because our thinking is on a human sized level, and thus we say they broke a law when they were here before we even existed.
That's not true at all. Certain laws must occur by virtue of mathematical principles. For example, Heisenberg's uncertainty principle *has to happen*, mathematically, there is no other alternative.
Anthony Khodanian Yea, but math is nothing more than a human construct designed to explain and describe certain observable natural patterns. Heisenberg's uncertainty principle might turn out not to apply to some of those patterns. Of course until there is solid observational evidence of this its better to assume that it applies in all instances, but the possibility can't be totally discounted.
Anthony Khodanian How when you go into a black hole then tell me what applies then. Until that happens I don't care much about whomever laws you think is valid or invalid. My point still stands true. Nothing is breaking laws, you're just creating laws for them to break.
If the universe breaks the law, who arrests it?
That is an interesting idea. It has always bothered me when people say a natural phenomenon is "breaking the laws of physics" because when you think about it, the laws of physics are simply man made rules that we have created to explain an event. If we see something happening that seems to violate that law, it would seem that the law is at fault for missing a feature of nature that we did not anticipate.
what if the big bang was a white hole from a black in another universe?
Another possibility for this to occur would be when an evaporating black hole gets below its singularity threshold. It would become this kind of huge, high energy explosion, since everything that was kept in, could now again escape.
Fascinating, keep up the awesome work guys.
Nothing makes sense. Thus everything makes sense!

I wonder, why are the laws of physics as they are, why are we assuming they can't ever change or evolve over time. Its not like there is a mechanism to keep them in check.
Scientists try to assume that the Universe works as simple a way as possible, given the observations that they make. It's just a general rule that helps them not make crazy assumptions when they don't need to. A universe where the laws of physics change over time is more complicated, so unless they have evidence for that happening, they assume that it doesn't.
(That "simplicity rule," by the way, is what scientists call "Occam's Razor.")
if we think in a purely theoretical way, the laws of physics are simply a list of rules that are almost unable to be changed with our current technology. it is possible, that each of the laws of physics can be broken, however, we do not possess either the understanding, or the technology needed to do it.
MrRockranger1 I was not saying that We could change or break the laws of physic, it is impossible in my opinion or extremmely unlikely.
What i'm trying to say ; These laws appear to be random, there seems to be no mechanism or reasons for them to be the way they are. And if it is the case, why do we assume the rules are fixed. Maybe we don't have the power to change or bend them, but the forces of the universe are way more powerfull than us.
It could be possible for some of the rules to change over time, to change for a fraction of a second if there is enough energy in one point, to change a bit when space strech or compress, or because of the effects of extreme gravity. Not to forget that time isn't linear, gravity speed it, and where there is none time flow more slowly. These small differences on a gigantic scale over a long period of time might have an effect on space and its laws.
Anyway, my point is; we should not assume that the laws of physics are the same over time everywhere. They might have changed slightly since the big bang.
well you are right in a way but remember math and our current laws are all human made wich means we will never be right at start and may never get to understand the whole universe in its whole since every now and then there is this random apearence
Good point, since we made the "rules" up by math, why should the universe feel conformed by these rules? Clearly it does what it wants, rules or no.
In case anyone's curious, it seems that the current most likely explanation for GRB 060614 is a black hole/neutron star merger, or a similar event. Hopefully we'll see more things like it!
Thank you for coming back years later to update us. This is exactly the comment I was looking for after remembering seeing this video back in high school lol
@@Michael-Hammerschmidt I'm guessing this won't be seeing much press anymore since mergers like that are now known to be pretty common and not very newsworthy, but it's the sort of thing I'd still love to see followed on with in popular science someday.
I just don't understand one thing... Why does it necessarily have to decrease entropy? Drop a piano into a black hole, it turns it into splinters, white hole shoots it out in a form a splinters. No entropy violated.
It's like an like an endless game of chess, no victory or defeat but a continuous game between two ideas, like mother nature and father time. Or simply hit the reset button or rematch of the opponent over and over again.
It necessarily violates the second law. The law states that no matter what, so long as time keeps moving I'm the same direction, things will always move from more ordered states, to more disorderly States. Even when something clearly creates more order in some things state, ultimately, in the larger view, the sum total of order in the universe, is decreased by every action. When you use your a/c to increase the uniformity of energy levels / heat in your room, the a/c still increases disorder more than it decreases it in your room via expelling all that energy outside, as well as creating more disorder through thermal transfer, inefficencys of mechanics, and a host of other things. In fact, time, is often defined via entropy in physics. If white holes pop up, take all that chaotic matter, and spew orderly objects, unless it also increases disorder somehow/somewhere else at the same tie, its necessarily violating the
Law, see? Not saying they do or don't exist, just that it would appear at least to violate the laws.
But white holes aren't shooting out splinters, they're shooting out pianos. All sorts of pianos like grand pianos, upright pianos, pipe organs, and keytars.
I think I missed that whole it shoots it out as splinters part though... I find the idea of white holes still hard to get into for some reason, I suppose, because the gravitational field seems to stick, so, mass/matter/energy concentrations must be.. at least fairly stable, not withstanding the idea mentioned in a thread further above involving plank star's and hawking radiation... still... I dont know anymore than anyone else anyway, just like to post sometimes haha :) thanks
From what i understood it would not spew splinters but a full piano, is like making a video run backwards.
I'm not saying it was aliens, but...
Reality is more terrifying than fiction.
Maybe it was some distant civilization discovering time travel, reversing entropy and obliterating themselves in the process. That's a fun idea, right?
Just those pesky aliens having a war
The King Of The Potato People A Stars War... er... Star Wars..
You cant put wood pieces back through a wood chipper and have a piano come out.... Last time i checked, the properties of theoretical white holes, never involved it shooting out, full fucking planets and stars -.- That analogy was absurd..
+Anthony Smith Thats exactly what i though! made no sense
+Anthony Smith Yeah; if white holes shoot out photons, they'd emit about the least amount of information possible.
But still, a photon contains more information than.. well, empty space of nothing. So it would still be a decrease of entropy. But if they come from a singularity, that actually has mass, and therefore information.... things get tricky, right? ^^
+Selmokk unless all of that singular mass was broken down right? I mean wouldn't that basically be the black hole being the wood chipper entrance and the white whole being the end where the chips themselves come out? Does it really seem so unlikely that a white hole is the opposite end of a black hole? We have no real idea what happens inside of a black whole or where they might lead and space is so vast and endless to us that it is probably a 1 in infinite chance that a white hole would end up in our neck of the woods.
True. i still like the theory of our universe being the inside of a Black Hole; that would even make White Holes even more plausible, as the primary way of matter that falls into "our" black hole to end up here and totally not violate any laws of physics at all.
But that's of course just a theory.. one of many.
The way white holes are being talked about, is the exact same thing as reconstructive teleportation. Black hole eats somethings, punches that matter down into its purest form of energy and then shoots it out somewhere (a white hole) where as it comes out, that energy is reconstructed into what it was. Despite our understanding of physics breaking down in a black hole, that still sounds completely impossible and dumb.
Why no mention of the possibility of black holes and white holes being the ends of wormholes?
Because black holes aren't wormholes, you're getting your sci-fi mixed up again...
Teth47 Actually, the theory of wormholes has been linked to the theory of "white holes" as black hole exits since near its conception. There isn't evidence of this in nature, but it's theoretically sound and linked heavily to relativity. I did a paper on this last term - it's quite facinating stuff.
Netbug009 The problem is the source of the exotic energy needed to actually form a wormhole, gravity alone won't do it, so what other mechanism in a black hole could force spacetime to fold in on itself and join two remote locations? As far as I'm aware, a black hole is basically a region of spacetime so curved it forms a sphere around the singularity. At best it could be considered a small pocket universe, but there's nothing in it that would allow it to connect to another point in space through which to eject matter. It might make sense from a purely mathematical perspective, but conceptually, it's missing some pretty important components.
That being said, if you have a link to your paper, I'd love to read it, might clear up some of the things I mentioned here, I'm far from an expert...
Teth47 I don't have it posted online, sorry. And TBH this was an entry level class so I'd hardly call myself an expert either.
Still, the fact that we can even have this in=depth of a discussion on it kinda accents my point about it being included in the original video.
Netbug009 I have this funny feeling that you and I are not good examples of the average viewer of these videos, you with your educational background and me with my constant reading of goddamn everything all the time and autism-induced high data retention of printed words...
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?
Every action has an equal and opposite reaction. A black hole
sucks time and matter out of the universe: a white hole returns it.
So, that thing's spewing time back into the universe?
Precisely. That's why we're experiencing these curious time
phenomena on board.

***** It's from Red Dwarf
Oh, I've never seen Red Dwarf. I assumed that Khan made that up. I'll have to watch it at some point, though. I've heard many good things about it.
I have olny one thing to say LAWS WERE MADE TO BE BROKEN
Bryan Bower Like buildings... OR PEOPLE!
The laws of the universe are thought up by mankind. We'll never be absolutely certain if they are true or not. As such, the laws of the universe can be "broken".
It was a blast from the Death Star! ;)
Assuming that those who think that black holes are the entrances to wormholes are correct, could white holes be the exit? I think that's a really cool idea, sorry if this sounds stupid :P
Ive heard that before, but i think stabile wormhole theories ar frowned upon in physics. Also a black hole increases its mass proprtionate to what it sucks in(-hawkin radiation) so there isn't really any reason why there should be a wormhole at the center.
I think the hypothesis was first introduced to explain how the "information" would not be lost in the black hole, but i think that paradox was solved with hawkingradiation.
David Engen Ah, I see. Still a cool idea though :D
David Engen Well I don't know. So far HR is just a theory. We haven't seen any Black holes give off dim Radiation. Worm Holes could very well be a viable solution. I mean think about it, a worm hole opens up (white hole) spews out a bunch of shit for a minute like a drunk kid at a frat party, then collapses just to open up elsewhere.
deathscreton i feel like both the theories seem really odd. they both sound like it would be impossible to happen outside a quantum scale. time moving backwards on a large scale seems eaqually outrageus as a wormhole traveling HUGE amounts of mass a long distance through space instantly.
The wormhole doesn't move anything. All a wormhole is is a tear in space and time that connects two seperate points in space time. It makes sense if you read up on it.
what if a black hole is actually a "Plank Star" and what we saw was the Lightspeed Threshold shrinking past the boundary of the Star due to Hawking Radiation leaking away for a very long time???
it would be funny if that was the one white hole this universe was gonna get and never more would be get another one
2:48 It's funny how the sun is always represented as fire, orange and yellow instead of pure white
Contrast turned waaaaaaaaay down :P
What would time be like around a white hole? If it is a black hole played backwards but that can't happen because it would be decreasing the entropy of matter and energy in the universe , could it mean that time for a small amount of time (haha) was going backwards in a localized region of space around a black hole? I mean, I don't think there is such a thing as temporal entropy so time could theoretically go backwards without breaking the laws of physics. Only the things affected by that time would maybe sorta.
Whiteholes you cant go in.Black holes you cant escape! Wormholes. You go in the black, come out the white!
matter shoots out of jets from a black hole so maybe some stuff escapes...do they ever acually get in( the matter composing the jets?? )maybe they dont. if so, my bad......

If there was an alien planet, there should also be a star that planet orbits.
Unless it's a rogue planet, but they are usually lifelless.

I remember that episode of Red Dwarf.
So what is it?
maybe it's an intergalactic war that was being waged 1.6 billion years ago? anyone? no?
For 102 seconds? That sounds like a pretty short war
must be very fast living people...
Eddie Gruver Well, the fastest way to stop a war is to completely annihilate your opponents, as America figured out in WWII. I doubt you need more than 100 seconds to collide enough antimatter with the enemy's home planet to make a strong enough point.
"This giant nuclear device should convince you of our point"
Anthony Khodanian That must be a really cold planet if it doesn't have a star nearby. I would hate to be on that planet, so it might have been doing them a favor if it was a giant antimatter canon.
How would we know if time went backwards from time to time?
perhaps it does, could this be Déjà vu?
exactly! I never get why people say they KNOW time goes forwards, If it went backwards we wouldn't notice a thing, we can only feel time moving forwards!
Malus Draco No. If time goes backwards, so does your brain, you wouldn't notice anything
When you realize time is something humans created to measure passing events , it's absurd to consider that time can go backwards.
Lord Rith That is a common misconception. I recommend reading up on subjects like time dilation and Einstein's relativity theory. You don't have to understand the physics behind it but just grasp the concept.
Well, I mean, it WOULDN'T decrease entropy. Its not like a White Hole would spit out full planets and shit, its just raw matter. Entropy remains the same.
ChampionGold good point but at the same time how would we know what form the matter had before exiting the whitehole
it would however spit out a large cloud of matter that would then condense into planets, so not whole planets but planets to be.
ChampionGold isn't big bang a giant White hole before it disappear?

This is the best science show I've seen so far. Bar none. Thank you for sharing.
Well couldn't a white hole just be where a black hole expels whatever is sacked in it? The flip side of a black hole.
a black hole forms when so much mass has been condensed down to such a small point that light can no longer escape. so no, just expelling matter from a black hole wouldn't be a white hole, it would be a major violation of the laws of physics. also, a black hole would go from black hole, to white hole back to black hole, that would require more energy than remaining a black hole.
*sucked
theguy9208 but what if a black hole was the entry point to a wormhole? Don't you think what goes in has to come out. So if there was a black hole some where millions and millions of light-millenias away, couldn't there be a white hole somewhere else like on a few hundred light-years away?
***** MAny things are expected and yet not happens. We still know very little about our universe so maybe it is the thing that happens. Who knows?
Probably not cause that'd mean that white holes are as common as black ones.
Do wormholes exist?
If I recall the reason relativity says that time can move in both directions is because it says it DOES move in both directions and that time's arrow pointing towards more entropy is merely how we perceive time. If this is the case then all black holes are stable long-lived white holes to anyone who could experience times arrow in reverse.
So I guess once you go black, you can go back after all.
Larry Wilmore proved that once and for all.
"Black Hole" played backwards isn't "White Hole"!
It's "Eloh Kcalb" ;)
Science is light on "Eureka!" moments and heavy on WTF?! surprises. It's bizarreness like this that gives us opportunities to advance our knowledge by leaps. I'm excited about this!
This was clearly an Alien time experiment,they were going big.
Question:
Was Big Bang a White Hole phenomenon?
That sounds like an excellent theory.
Your question interests me. Keep it up, dude.
according to that you mean
let say a white hole existed then it spits out matter and that is what we came to know as big bang (let say) and for some reason the white hole after turning into black hole wasn't able to suck up everything OR the white hole just vanished without turning into black hole
then came so much called universe and in that earth and so we existed
therefore we can say that before that white hole came it should have been a black hole or something sort of that which can store matter in different form (with more entropy) and before it was even that kind of thing it should have been something to begin with to turn into black hole type of thing and that something should have been surrounded by matter /space etc.
from this we can conclude that universe ( i am talking about full universe include dark matter and dark energy) behave like a wave
there is universe then comes massive black hole type of thing and sucks universe destroying everything increasing entropy and then turn into white hole to spit out every thing (maybe in different configurations)
That just sounds sexual
2:14 How do we all know that? The way i see it, if time flowed backwards then we wouldn't have any chance of noticing it. All the particles inside our brain that makes up our memories would also travel back in time and our memories of the present/future would be erased. Thus experiencing time backwards even if time does flow backwards would be an impossibility. It could very well be that it is only our experience of time which is one-directional, since there is no other way for us to experience time.
ohh no... Swift detected my top secret nuke test...
Brian Su How'd you get it to last 102 second?
Joshua Richardson it doesn't... but time is relative. just accelerate the test site close to the speed of light and it'll appear to last 102 earth seconds :)
Maybe our universe is the result of a white hole?
shut up before you blow my mond
*mind
+ReviewDogeUSA That's exactly what I thought. I mean, the Big Bang the result of singularity - I know little about physics, but it sounds plausible to me that the singularity that caused the big bang could of been a white hole.
So I just did a quick google search, and what to you know, it's already been proposed. It doesn't seem to be a very popular idea, but the idea that the universe is the result of a white hole actually being considered by some physicist. So it could actually be possible!
So you mean we came out of a giant white woman's butthole?
I have a theory that black holes are a construct from an object that exists in the 4th dimension. We cannot understand this object, as it does not follow our 3 dimensional paradigm, resulting in a structure that seems to defy the laws of physics. I have two ideas of how these structures would work. Firstly, this object does not only take matter in and compress it to a singularity, but it also ejects it from the other side, in what is known in math as a white hole. The bias for time occurring in the manner we see today is reciprocated on the other side of this construct, resulting in a universe essentially playing in reverse. When an object reaches its Schwarzschild Radius, the object will have sufficient density to break the 'wall' of the universe. Another idea that I had was that the universe could be a 3rd dimensional construct of a 4th dimensional object, or a hologram. Analogous to how shining a flashlight on a 3rd dimensional object will cast a 2nd dimensional shadow, our universe could be nothing but a shadow of matter stored on a supermassive black hole.
Entropy doesn't say that order can't happen... it says it's more probable to be disorderly because of the many more ways it can be disorderly.
Oh and Black holes doesn't "suck". :p
I understand that they are COMPLETELY impractical. But if a white hole were to happen from the last black hole during the theory of "the big crunch" it may help explain the creation of the Universe. (feel free to tell me how I'm wrong, but it was just an idea)
It's funny because that is a legit theory proposed by scientists that still stands today.
You're saying the Big Bang could have been a white hole? If so, that would be an interesting theory.
Mariner35 That's exactly what I'm saying. If white holes eject matter, what would happen if every bit of matter got sucked into one, final, black hole, and then some reaction causes all matter to be ejected into the once filled void. Maybe the universe just resets after a unexplainable amount of time
Thats really interesting! I would like to know more about how time could "move backwards". It doesn't sound like something that could happen outside a quantom size.
The idea is that many parts of physics don't really care about what "direction" time is moving in. The equations balance out no matter what. However, some parts specifically rely on time going forward. The second law of thermodynamics is a good example of this.

Jesus Lord its nice to see you take an interesst in science. i feel like alot of your followers dont do that nowadays.
"No one's ever seen one before, but I think it's a white hole."
"So what is it?"
"No one's ever seen one before, but I think it's a white hole."
"So what is it?"
"No one's ever seen one before, but I think it's a white hole."
"Someone knock him out!"
"So what is it? ... Only joking!""
"I think we've encountered the middle of this conversation."
"So what is it?"
"Someone knock him out!"
if you say, a white hole pushes everything from it and at the same time decreases the entropy (basically creating a piano/in this case more like a new star(?)) wouldnt that mean, it had matter/information at the beginning? but if it does push EVERYTHING away, how can it have information to begin with? it would have to release all information at one big moment right at the beginning of its existence. but, say a white hole is a 'negative' of a black hole, that means it has a lot of matter/information compressed in a single point. release that in one single moment and where would you put all that matter/info? and where does that information come from? to get this much info into such a tiny little point, mustnt the white hole be an 'ex'-black hole? if so, why would a black hole suddenly change from the ultimate vacuum-cleaner to a ultimate vending--machine?
I was thinking the same thing. That hypothesis would allow for the issue of lost info in black holes disappear. Hawkins might personally thank you for proving such a thing.
Nothing is lost inside a black hole. It gets released again as Hawkins radiation.
Or, because of the effects on time gravity has, a white hole is where a black hole surpasses a certain density and temporarily reverses time. Like how relativity doesn't care which way time goes. While black holes do take in information and re emit it, white holed occur when too much acmulates at one time. what is reemitted is the original information that was absorbed.
White holes could be black holes reaching a maximum density per area that then remit information back into it's environment until it before below the density maximum, which then destabilizes it back into a black hole.
jacob archer But we know of black holes that are 12 billions times more massive than our sun. And that's the biggest one we've ever discovered, and they didn't become white holes.
But, your idea about reversing time is interesting. I should read the equation for time dilation and try to see if certain values give a negative time dilation.
Shonfrost I'm betting there's more to the nature of black holes than we realize, and that there is a practical maximum amount that the hole will take in and still be stable. Like that massive black hole, it probably hasn't exhibited white hole characteristics because it either hasn't absorbed enough in the timeframe that we've observed it. I'd like to see if anyone has an estimate for amount of material expelled during the 102 seconds of white hole lifespan.
Wow, that is quiet a slap at the scientists: "No, it can't exist." Other scientist: "I just saw it happen." Scientists: "........"
When did scientists flat out say "It cannot exist". The math is all there they just said that it was unlikely. Re-watch the video.
@@alucardwhitehair Unlikely basically translates as "It cannot exist"
Ok, here's how I think this complex stuff works:
Black holes and white holes would probably work along with quantum mechanics. Black holes have information-carrying quantum particles orbiting the singularity that can scan matter, like a quantum computer and then destroy the original matter, but shoots the information on how to create the same matter out of a white hole somewhere else in the universe. This wouldn't be a problem since we know that quantum particles can communicate faster than the speed of light using "spooky action at a distance". We have already done this method of teleportation using single photons so maybe black and white holes are like quantum "servers" transferring data which is ready to be interpreted and reconstructed at the other end.
If so, does this mean black and white holes qualify as nature's own computers? And how powerful would they be?
this. is. AWESOME! :D
Hi atheist from Norway :D
So, it's possible to break the laws of physics, but only until the universe realizes that we broke it, and has some internet lag fixing it?
There is a theory that floats around that the universe will become so entropic it will become self-aware.
Keep in mind that the second law of thermodynamics applies to a CLOSED SYSTEM ( are there any truly closed systems in the Universe?... ), White holes must exist to counter the entopic nature of black holes otherwise the Universe would have degraded to nothing long ago.
Uuuhhhhmmmmm I'm a bit lost. If, for relativity, time can move either way wouldn't that make possible to reverse any kind of increase of entropy? Why just black holes?
Because you are cursed and in need to seek higher, more powerful souls.
Frederick Fournier Lehoux Dark souls reference? Oh he has that icon, i see
That's a good question
Because, in practice, time only moves forwards, as we all know.
Cause black holes are cool

I like this presenter. White holes, black holes, all of it boggles my mind.
It was actually a super weapon deployed in the middle of an alien space battle that wiped out both sides.
Well, it sounds cool at least...
We've witnessed the end of the last Time War.
I wanna see the guy who breaks a piano down by hand into a billion or so pieces, and then rebuild it. I say it is possible. Every law can be broken under the right circumstances.
You can't reconnect atoms that have been broken without it still being two separate objects. Like he said you can't reverse the wood chipper then get a piano back out the front
You can pump a molecule of water full of energy break it back down to 2 Oxygen and Hydrogen, then have them bond together again to create water.
+DoctorNerd there is going to be nails in it.
+DoctorNerd that also creates an explosion. increasing entropy
+DoctorNerd Entropy is powerful. It is the natural state of the universe. This is why it is easier to destroy than create.
I seem to recall reading that when black holes were first described, similar language was used to talk about their existence. I wonder if white holes will become a popular topic now, too?
I'm not saying it was a white hole,
But it was a white hole.
SciShow Space, Have you been watching Red Dwarf?

M0rningfoolsgold Red Dwarf is an awesome British scifi show, you can stream it on Amazon if your a prime member for free!

M0rningfoolsgold lol, ok :)
I'm so happy I stumbled upon this channel
Holy shit, This is amazing! I need to look up more on this, This completely supports string theory! :D
um...how
quantum mechanics supports the idea of multiple universes. This idea came to be because the only way the big bang could have been possible is if Gravity was the strongest force. But right now it's the weakest. This is because gravity has to travel through multiple parallels causing it to become weaker. This also adds an explanation to the origins of dark matter.
Gorognaer Andre
I think he means how does the flash support string theory
daydodog I just explained.
Gorognaer Andre I think he means how does a white support string theory
If the second law of thermodynamics says entropy must increase or stay the same, wouldn't the existence of white wholes and black holes essentially level out to zero change in entropy? Then the total change in entropy in the universe still stays the same, they exist and the second law of thermodynamics is conserved since entropy can only increase or stay the same.
it still decreases.
its like oh no im not subtracting
1+1-1+1
+Levi Howell Not exactly. A black hole would come along and increase the entropy to a point. Then a white hole would decrease that point the level of entropy was at. There basilica two different equations that involve the same number.
+Levi Howell Of course, the law might simply be wrong.
I came to this video on the inspiration that white holes (if they exist) might be the means buy which the universe 'recharges' itself. In tandem with black holes. Although the black holes radiation might preclude that.
Roger McKay The problem with that is Something can't be made a law unless there is absolutely no possible way that it can be disproves. We know beyond a shadow of a doubt its correct. I'm not saying your wrong with your suggestion, but it would take a huge breakthrough in science and the way we understanding things for something to be no longer a law.
I know this video is a bit old, and all of you at Scishow Space probably won't see this comment but I just watched this video again and I thought of this:
If the second law of thermodynamics says that entropy can only stay the same or increase, then a white hole technically is still possible because it would essentially work with a black hole in that the two would cancel each other's entropy out. The white hole wouldn't necessarily increase entropy throughout the universe, it would simply cause it to stay the same when you looked at the universe as a whole. I'm sure others have thought of this as well and this is possibly the way it works out in math, but I wanted to see if this would solve the conundrum of white holes.
Great video as usual!
If I looked through a telescope and saw a piano, I would expect it to have been made by sentient beings, because statistically it's extremely unlikely for it to have formed by chance. I think we should at least consider the possibility that this was an alien beacon.
***** There's almost no evidence to work with. All we have now is the observation of what could have been a white hole, the existence of which would contradict the second law of thermodynamics if it occurred spontaneously. If it was caused by sentient beings (in which case it almost certainly wasn't a white hole) then there could have been a mechanism that kept the total entropy change positive, and the 2nd law wouldn't have been violated.
So thus far we have a few options:
1) It was a white hole, meaning the 2nd law was violated which, while technically possible, is so unlikely on this scale that the odds of it happening are one in a number too big to be fit in the observable universe using this font size.
2) It was some as of yet unknown phenomenon.
3) It was an alien beacon: not necessarily a white hole, but some intentional release of energy meant to simulate one.
I'm not at all saying I think it's option 3 (If I had to put money on it, I'd go with option 2). But I do think it deserves to be on the list, if for no other reason than because there's really no better way to show the rest of the galaxy there's sentient life somewhere than to create a luminous beacon that looks like a white hole.
An alien beacon which they set up to transmit no information? If the aliens are smart enough to do this, surely they could at least make a beacon recognizable as being made by intelligent life
Realthx It has the most important piece of information: their location. To convey any more they'd have to do something like (I suppose?) a series of pulses, but if they spent their available energy on that instead of one large one it wouldn't carry nearly as far... and you can't (to my knowledge) convey much meaning that way... sure it's a binary system (flashes and no flashes) but the only reason we can form logic gates from binary inputs is because we use transistors that have switches controlled by the input.
Was thinking a recognizable pattern in nature such as pi, but anyway, this thing happened millions of years ago, if it was caused by something, they have long died out
energysage I think if the aliens were intelligent enough to create that much energy they would also have a way of communication without wasting so much energy.
The more I read about religion and its arguments the more I lose faith in humanity. It's just sad.

***** Christianity Doesn't Cause Anything. Real Christians Aren't Running Around With AK47s Killing People

Just want to complain? RESPECT is the beggining of EVERYTHING...respect those who follow whatever religion, and hope they respect you will to follow whatever else too...all the BS and wars would END if we just respected one another...but no...we must force others to think exactly like we do...its the only way right?...
***** -Why should you care in 1st place? Why is it important to debunk or not religion? would that change anything at all?
My only thing with something like this. "The universe does not like it when you break the laws of physics" the laws of physics is something we human more or less created. The universe doesn't HAVE to follow the law of physics that WE understand. It's completely possible that the universe doesn't follow any of the laws we believe in because why does it have to?
what about antimatter? Couldn't that be the cause?
Call me an idiot, but isn't refreezing an ice cube decreasing entropy? Idk I'm new to the whole entropy idea.
+Nimesha Jayathunge We are living in so called Goldilocks conditions, so, here all kinds of things can both increase and decrease. When they talk about entropy only increasing, they talk in the large scale in the universe:) (There´s one Sixty Symbols episode here on this matter, which is good.)
+Nimesha Jayathunge Blah
Sorry for being late to the party,, even if you are pumping heat out of the ice cube, you are still putting that heat into the universe and that does increase the entropy of the universe.
Nipun Ramani Oh, ok. Thanks.
Thumbs up for my brain totally cracking in half after watching this! MIND = BLOWN!
What if stuff that goes into a black hole comes out of a white hole like the wood chips baldy is talking about?
Yeah I'm in no way qualified to say that is correct or incorrect, it'd just be cool if that's how it worked. Stuff goes in a black hole, gets 'chiped', and the white hole is like the output of the wood chipper, where all the chipped up stuff ends up. That wouldn't be decreasing entropy, that'd just be conservation of information.
It'd be a cool concept for science fiction, and no I'm not stating this as an oppinion, or trying to say that is in anyway something that's likely true, it's only a fun little thought.
exactly what i am thinking as well. it is a great idea, however we do not know yet... :( but i want to know!
+MarklenIngyer i read on another comment that this already exists and is called "quasars"
Renie Roivas
Quasars are stars...
+MarklenIngyer it makes white holes much more likely and +Renie Rovias quasars are nothing like that. quasars are the accretion disks of a black hole if they spin so fast they glow. they spin so fast they can give off gamma ray bursts that extend so far that they make our entire solar system look tiny. a white hole would be nothing like a quasar.
+MarklenIngyer quasars are not stars, there much more like energy beams that are shot out into space from the center of a huge black hole

AuthenticDarren Aw man, another race was nuked on a larger scale out there. Well, we must look on another point in space now to find other aliens. Another flash happens. Crap, another race died
Their goes the on;y aliens alive.
While the video is interesting. The data is from 2006. What's happened in 8 years?
Nothing else of the kind, I presume.
nothing new on the matter, most likely. no changes to the laws of physics allowing it to actually be a white hole, no new discoveries showing it to be something else. it's quite possible whatever it was is a very rare occurrence, and it could take a long time before the energy from another one reaches us again
I was about to say, wouldn’t a white hole be like another Big Bang INSIDE our already banged universe?
I´d say, that there is a white hole on the back of a black hole - stuff has to go somewhere, right? ^_^
