I don't understand how things condensed after the big bang, I was told everything exploded from a singularity and then condensed into planets. But space is a vaccum and if everything exploded in a vaccum then everything should just keep expanding in that direction forever. no condensation could ever take place.

The big bang is not a explosion in ordinary sense of the word. It's a sudden rupture of the equilibrium condition present in the singularity (the primordial source). The cause of this explosion is not known/ cannot be known. Our space and time starts with this explosion event. Initially it was just energy - light (photons) mix which got separated in and elementary particles like quarks etc got formed. Photon / light particles got decoupled from other elementary particles.cont..

Cont from last mail.. After that the simplest element like hydrogen atom followed by helium, beryllium and boron got formed. Now after the initial explosion, the energy distribution was not uniform/isotropic. So, there was minute fluctuations and there the mass started slowly accumulation. When lot of mass accumulated, the gravitational force dominated and condensation started. This resulted in star formation. Other elements are were produced inside the stars. Cont...

This is the third part... read the previous two.. But as the fluctuations in initial energy distribution are very sparse, much of the space is void. In between galaxies there are much space. The expansion continues. Space goes on expanding by creation.

Did I answer your question?

so where is the god out there? can you imagine cose i dont eaven try to...

@2012Video

What do you mean by the concept...GOD???

youtube: Earth is older than the sun. Scientists still don't know what caused the planets to lose their angular momentum. My theory solves this. They are themselves cooling stars that are much older than the sun.

@BurtonRGA7 because of that, most rock debris are accumulated at the equator and not on either north nor south pole? (sorry, having a hard time grasping this fact)

[BurtonRGA7]

@MidnightRedemption

because of the centrifugal force that is present in any rotation

[MidnightRedemption]

why does space rocks orbiting in a large body always to be a like a discs, like rings of jupiter. why not a sphere of space rocks orbiting that sun?

This was great. My astro teacher is so boring

@affluence8 It sure does. The best explaination I've heard so far.

[affluence8]

@jayantgang Does space go on forever? Or is there a wall way out there that says " This is the end" ?

[affluence8]

@RespectMyHate they explain it in the Bible.
