SUMMARY

The Big Bang is not an ongoing event; it occurred approximately 13.8 billion years ago and is characterized by the initial singularity. Researchers have traced the universe's history back to 10^-37 seconds post-singularity, indicating that the universe has since cooled and formed matter. The movement of galaxies away from each other is explained by Hubble's Law, which describes the expansion of the universe rather than a continuation of the Big Bang itself.

PREREQUISITES
  • Understanding of cosmology concepts, specifically the Big Bang theory
  • Familiarity with Hubble's Law and its implications on cosmic expansion
  • Knowledge of the timeline of the universe's formation and evolution
  • Basic grasp of scientific models used in astrophysics
NEXT STEPS
  • Research the implications of Hubble's Law on the expansion of the universe
  • Study the timeline of the universe from the Big Bang to the present
  • Explore the concept of cosmic inflation and its role in the early universe
  • Investigate the formation of matter post-Big Bang and its significance in cosmology
USEFUL FOR

Astronomers, astrophysicists, students of cosmology, and anyone interested in understanding the origins and evolution of the universe.

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?
 
Astronomy news on Phys.org
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)
