Could a White hole be responsible for the creation of our universe?

[Gelgoog]

As in a white hole being the exit point for a black hole, and the matter that a black hole sucked up was spit out to create our universe....or the fact that our universe is just the inside of a black hole. These are some of the theories floating around trying to explain where all the matter goes that is sucked into a black hole. Some of the scientists think that a white hole would be a good explanation for the origin of our universe.

[Gordon Freynman]

Maybe, but I have serious doubts about it. It would have to be a super-ultra-mega-massive-blackhole to account for the amount of matter in our visible universe alone. Inflationary Theory still wins out in my mind.

consider the big crunch where all the matter in the universe is sucked back into a black hole.

[Gordon Freynman]

consider the big crunch where all the matter in the universe is sucked back into a black hole.

Yes, I suppose that could provide enough matter to fill our universe.

[Alkarin]

possibly.

I oddly enough had a similiar discussion with my Chemistry Professor just the other night. And we thought it would be more logical, that black holes are what contracts the universe back into a singularity and the critical mass of a singularity would indeed be all the matter in the universe therefore creating another big bang. Since the common consensus of the matter going into a black hole is that it is simply being condensed into a singularity

But what I've heard is that most top scientists believe that there will be a freeze death, rather than a compressing back to a single point.

care to elaborate?

[empr guy]

care to elaborate?

instead of the big crunch its called the big rip. in the second senerio the universe never stops expanding, and like he said even atoms are torn apart.

[Ulyaoth]

I've heard it explained that the speed of expansion should be slowing down, but it's actually speeding up, meaning it's defying gravity, and something else is pushing the universe farther and farther apart. Therefore, eventually everything is supposed to get so far apart that energy will be so far spread out that not even atoms can hold together anymore, and the universe will turn into an extremely nondense pool of low speed photons.

Hey, according to the false vacuum theory the universe might cease to exist within a fraction of a second without any warning whatsoever

Okay, a black hole singularity and the singularity at the Big Bang are not the same thing. A BH singularity is caused by the collapse of a star. The BB was caused by a speck of negative pressure at the quantum level that then inflated about 10^25 times in a fraction of a second. The Super force that filled this volume then cooled and split into the fundamental forces we know today (electromagnetism, the weak and strong nuclear forces and gravity). The separation of the Super force also created the energy that became everything in the universe. No observational evidence exists for “white holes”. BHs do not appear to lose matter to a WH partner.
Dark energy is perhaps the energy of space itself and it is causing the acceleration of expansion of the space between galaxies. The more space you have, the more dark energy you have and the stronger the force of expansion. If dark energy levels increase at the present rate then in approximately 22 billion years the DE will overcome the strong force that holds atoms together and you get the Big Rip. Also, Hawking radiation has never been directly observed, although it should exist if our understanding of quantum physics is correct.
The inflationary universe rules scientifically. Check it out.

... what if once there is a complete heat death, a universe can spring up randomly out of the blue from one of these smallest pieces of existance? If the universe can end whenever it wants, surely on the subatomic scale it can randomly do other things. On that level things happen by chance anyway. At any time on the smallest scale something weird and unpredictable happens. I'm pretty sure this is fact and proven observation, or at least theorized though for the life of me I dont' think I'm putting it in words very well.

the matter taken in by black holes is slowly leaked out by hawking radiation, which has been directly observed.

and the universe will end through heat death. I.e. complete entropy.

[Slaytaninc]

Scientist don't really know. Certain hypotheses, gain favor over the years, but there's not enough actual evidence to predict either way.

well heat death will happen unless something happens first, and it's the only one we understand completely 100%

"White hole", "black hole".

Those sound a lot like figures of imagination .

Except we already know that black holes are real. We just don't fathom how they work preciesly and what happens to matter once it hits the singularity.

Don't mind him, he's still stuck in the victorian era. He thinks flintlock pistol duels are the way to solve your disputes and that war is a great way for a noble to achieve fame and honor. Cosmology is a bit beyond that methinks.

Now boy, that's a figure of imagination!

Black hole?
Kinky.


To the thread.How did that white hole came to existence?
