But as density increases, approaching 10⁷⁵ times the nuclear density, this repulsion begins to dominate.

But not in black holes?

[BipolarBob]

Oh no. The creationists have had it now (insert sarcasm).

[Publius6961]

This is an answer?
Just postulate another universe and hope nobody notices? or worse yet, ask that damm embarrassing question...

... WTF did THAT universe come from... ?

[Gordongekko909]

Nope. Ain't dense enough.

[Hodar]

Black holes are balloons compared to the singularity.

To paraphrase Stephen Hawkins "When God said 'Let there be Light', the question isn't whether the universe burst into existance; the question is 'Did God have a choice?'.

There's some good information here that's way over my head. Black holes are in the neighborhood of 10e35 times the nuclear density, nothing near 10e75 (unless I'm severely mis-understanding my physics - which is entirely possible too).

just before the Big Bang occurred, another universe very similar to ours may have been contracting

I thought we already decided our universe is destined to expand forever; in which case such a universe is not that similar to ours.

The current researcher seems to have a different opinion about our universe's fate...

[Kenny Bunkport]

Using a theory called "loop quantum gravity," a group led by Penn State professor Abhay Ashtekar has shown that just before the Big Bang occurred, another universe very similar to ours may have been contracting.

Where did that universe come from?

The "Hindu" and Buddhist cycle of creation and destruction.

[WestVirginiaRebel]

Yeah, but what about the coming Gnab Gib?

[Mazda3Fan]

I love this stuff, trying to wrap my feeble mind around such complex theories.

[ADemocratNoMore]

BTTT

[nonsporting]

So now a "Big Bounce" replaces the "Big Bang." Apparently an unspecified number of them.

So, how did this start? Or did it have no start, but has been oscillating in this fashion for eternity? How can we know?

[RobbyS]

Talk about mythology. Back to infinite regression.

[org.whodat]

"loop quantum gravity,"

Would you not get more defined results by peeing in the wind.

[RightWhale]

It is an idealized set-up which does not connect smoothly to realistic cosmology

This is polite language.

[freedumb2003]

Scientists may finally have an answer to a "big" question: If the Big Bang was the beginning of the universe, what could have caused it to happen?

Kids playing with matches.

[Redcloak]

Since the "current" universe seems to be flying apart and showing no signs of an eventual contraction, what prevented the "prior" iteration from doing the same thing?

[dr huer]

Einstein's space is curved by the presence of matter, and the volume of the universe is believed finite. Time looks straight, but not necessarily so, and our universe's future could be directly connected with its beginning.

[calex59]

Ok, so now tell us where the other universe came from and how did it start? This doesn't answer any questions at all but makes more questions. This is a typical trick of scientists to make you think they have solved a big mystery when in reality they couldn't solve it so they made something up to give the illusion of solving it.

They did the same thing with the origin of life, it is impossible for it to have occured on earth the way they theorized so now "life came to earth on a meteor or some other rock from space" as if this explains it when in reality the same old question looms: How did life start?

[rbg81]

Personally, I think most of this stuff is mutual you-know-what by physicists. There are some things that just aren't knowable, and the Big Bang is one of 'em. If there even was such a thing. Unless you believe in G-d, the thought of something out of absolutely nothing is just not credible.
