Natural Science Forum / Physics / Research / March 2008Thrust of Big Bang
If I look at a simple chronology for the Big Bang, I see that there's a period between the advent of the big bang and then maybe a few million years out where there's enough hydrogen and helium gas for the first stars to form. It's immensely fascinating, and I have a question is this. Where's the gravity? What keeps all of this newly created matter from sinking back into a singularity, black hole style, to begin with? > If I look at a simple chronology for the Big Bang, I see that there's > a period between the advent of the big bang and then maybe a few [quoted text clipped - 6 lines] > What keeps all of this newly created matter from sinking back into a > singularity, black hole style, to begin with? The Big Bang was an explosion of space, not in space. It was shortly followed by the the era of Inflation. That rendered our lightcone out of an infinitesimal thermodynamically connected volume stretched locally Euclidean and cooled. Matter did not condense out of the fireball until everything was safe against recollapse. We're still in the original black hole. Every point in the universe is at its exact center. All 4(pi) steradians exactly equidistantly point to the Big Bang. That is the geometry within a black hole's event horizon. Light cannot escape for the simple reason that no path points toward escape. See? No problem.  SignatureUncle Al http://www.mazepath.com/uncleal/ (Toxic URL!

Nothing. It WILL recollapse---if the matter density is high enough. However, it will not necessarily recollapse---if the matter density is low enough. Think of a rocket fired from Earth---it will eventually fall back down, unless escape velocity is reached, in which case it won't. The gravity is still there, but if the escape velocity is reached, it will never win out. |
