if black holes slow time down would a white hole speed it up?

we know black holes can slow time down by gravity but what would a white hole do, would it speed time up? or just spew matter out into void to form new galaxy's? i dont think we found a white hole yet and they are theory still but its interesting though.

heres something to think about maybe we got it round wrong way, what if white holes are the entry point for instelar galaxy gates and what a black hole does is suck up energy and re use it to shoot the ship through the white hole entry point and out the black hole end with such speed its faster than light and would therefore escape black hole gravity effect???

since we now know that there are dark galaxies, that would mean that white holes reside in such. it would only be logical for the white hole to retain a passage into the light matter demension. then does that mean that the black hole, retains a portal into the dark demension? or all they all relative in comparison? or do i have white holes mixed up with something?

hey ok i found something

Firstly, it's important to understand that white holes don't exist in our universe, even though theoretical physicists have studied the concept. It's still important for the theory of General Relativity. They don't exist because they're incompatible with the existence of matter. I'm not a physicist, much less a mathematician, and to understand white holes, one would need a high amount of understanding in one of those two fields.

PS I'm betting that there is some misunderstanding about the nature of black holes. Black holes don't destroy matter/energy, but rather they destroy the information about them. They release something called Hawking radiation (named after Stephen Hawking, of course). It is impossible to reverse the process that created Hawking radiation, and recover whatever something was before it entered the black hole. This is important to understand because most people's ideas about black holes would violate the first law of thermodynamics.

Blackholes do indeed slow down time but it does not provide a clear space for any object to go through it.Blackholes are made up of a strong gravitational pull strong enough to pull stars.What it does is that it slowly pulls a star towards it,(its able to pull it in lightyears away)and takes it apart.It litrally tears it apart and absorbs all or most of it.Its completely gone after that.

Note that a star does not go through the black hole,the star is wiped out before it can evens reach the hole.The gravity around and in a black hole is extremely strong and dangerous.So far scientist have found that black matter and afew other forms of particles are the only things that could survive in it.Time might possibly be affected in the black hole but whether it is or not,anything that gets into grasp with a black hole is taken apart and gone forever.You wouldnt get the chance to seem time change.Some blackholes are so powerful they have been known to be located in the center of some galaxies and are responsible for rotations.

As for whiteholes,im not sure about that theory,sounds "made up" to me,i doubt of their existence but then again,there are many possibilities of existence purely for the fact that we dont know the universe that well.

Well well well...

Reminds of someone saying "black holes suck!"
(maybe that was me when I was drunk

OK people, black holes don't suck, in any meaning. A black hole is not a hole (not as such that is, it is a singularity, which can be compared to a "hole", or rather a pin hole...), and it is not even black.

A black hole is a former star, that has basically collapsed so bad that all of its mass is concentrated into a tiny sphere (well, tiny can still be a few thousand kilometers, more even). That means that the density of the object is incredibly high, and its gravitational attraction is also. That is why it seems to be black, because all light coming to it stays there, and thus we can't see it.

By comparison, a white hole would be an object able to cast enough light in every direction to always look perfect white! Though possible in theory, I doubt that any of those can exist.

Now, if a black hole "slows time down"... Well, yes and no. It is all relative. Because of its incredible gravitational pull, time also is distorted, but only when seen from outside: if one could go into a spaceship able to accelerate 1g, the earth gravitational pull (9.8 m/s² roughly), that spaceship heading straight to the center of the galaxy (our galaxy), when that spaceship would reach the point, the man in the spaceship would have experienced a 30 years trip. If then he stops instantly and gets back to earth in the same way, everyone will agree that he would be 60 years older than when he left. If I remember it well (he he I'm old already for school things...), earth would be by then not 60 years older, but about 60,000 years!!

Any search on relativity and black holes and such will bring a lot of answers to such questions. I posted already a link already on black holes. Very interesting page that explains a lot I think.

I'm moving this to space exploration. I know that your point is could your theoretical 'white holes' form gateways for spaceships, but as the discussion is inevitably going to lean towards an explaination of whether white holes exist , I think it will be better there rather than aliens and UFO's

Apologies, but semantics do not have to work in the Universe....

Is it proven that

a Black holes "slow down time"?

b That (because of our native thinking) the "reverse" (WOW!! White!! (something racial here?? LOL) ) logic takes place?

This is NOT flaming - just a realty check really - the juxtaposition of "black and white"?? I. personally, don't the Universe has any such "rules"

My 2 cs...

Do you think the Universe "obeys" any kind of symmatry? Black and white I understand but is the Universe bothered? Does it care?

I don't think anything that surpasses the speed of light could appear white. Light simply cannot escape at such velocities
