Could another singularity be about to have a BIG BANG?

Question

We all have heard" If it happened once"....With all the evidence of the previous BIG BANG and experience scientiest have in this area is anyone looking at this being a possible unlimited energy source and freeing us from foreign oil dependence? What is this source of energy?

Answer 1

The "big bang singularity" contained our universe.
In my humble opinion, if there was such a singularity in our universe (one that contained the same amount of potential energy to create a universe like ours) Wouldn't it have enough gravitational pull to suck in and annul our universe?

Answer 2

First, the big bang did not evoke "unlimited energy" in our known universe. In fact, our universe is so-called positive entropic, which, in effect, means it's useful energy is running down. It will, waaaay in the future, eventually end, with a whimper, when it's end temperature reaches absolute zero degrees Kelvin. At least that's prevailing theory at this point in time.

Second, the source of what energy it does have is, of course, unknown. So any answer given here would be a WAG, pure speculation. However, string/M theory has one possible WAG for the source...another universe. [See source.]

According to the cited source, higher dimensions (i.e., higher than our standard four dimensions) open up the possiblity of other universes just offset along one or more of those higher dimensions; so we cannot sense them. Brian Greene illustrates this parallel universe concept as slices of bread in a mega-universe, which is the whole loaf. Our whole universe, both known and unknown, is but one of those slices.

A hypothetically possible source of the BB energy would be if two of those slices of bread collided for an instant (actually one Plank time). The resulting rebound from the collision would create unimaginable (but not infinite) force and consequent energy...or, at least, a proto-mass/energy. There are some WAGs that posit mass and energy, as we know them, did not gel into our known universe until some time shortly after the so-called inflationary epoch, when our known universe expanded faster than light speed. [See source.]

Answer 3

The sequel to the Brian Greene book that the above person mentioned is called "The Fabric of the Cosmos," and in it he explains the theory of Inflationary Cosmology. According to this theory, the driving force of the expansion of the universe was actually... get this... gravity. Under certain conditions gravity can be an expansive force, and by starting with only around 20 pounds of matter compressed into near planck's volume, this expansion will occur and the energy that created our known universe was drawn from gravity.
