Is the Big Bang Still Happening and How Does it Influence the Universe?

[jumpjack]

How long did the big bang last? Is it still going on?
If it is still going on (as galaxies are still moving away), is mass still being produced? If mass is no more being produced, is the space between current galaxies positions and original big-bang-singularity position completely empty?

Of what I understand, the Big Bang was an instantaneous. The big bang represent the Singularity, where a Model must be use.

Then, researchers has been able to go back up to 10^-37 seconds after the singularity happened. Then, still based on the Model, out of the big bang, the universe cooled down and created matters.

So, no the Big Bang isn't going on at the moment.

If you want to read about why the galaxies are moving away away, search for Hubble's law (or simply go on Wiki for a rough idea http://en.wikipedia.org/wiki/Hubble_constant)
