Big Bang lasted for an instant, representing the Singularity, and researchers have been able to go back to 10^-37 seconds after it happened. The universe cooled down and created matter, but the Big Bang is not still happening. Galaxies are moving away due to Hubble's law. In summary, the Big Bang lasted for an instant and is no longer happening, with galaxies moving away due to Hubble's law.

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)

1. Is the Big Bang still happening?

Yes, the Big Bang is still happening. The universe is expanding and cooling down, which are key characteristics of the Big Bang theory.

2. How do we know that the Big Bang is still going on?

We know that the Big Bang is still going on through various observations and experiments. For example, the cosmic microwave background radiation, which is leftover radiation from the Big Bang, is still detectable today.

3. Will the Big Bang ever stop?

The Big Bang is not a continuous event that can stop or start. It is a singularity, meaning it is a point of infinite density and temperature. However, the expansion of the universe will continue as long as there is energy present in the universe.

4. Is the expansion of the universe accelerating?

Yes, current observations suggest that the expansion of the universe is accelerating. This is thought to be caused by dark energy, a mysterious force that counteracts the gravitational pull of matter and causes the universe to expand at an increasing rate.

5. How long will the Big Bang last?

It is impossible to predict how long the Big Bang will last as it is a continuous process. However, scientists estimate that the universe is currently around 13.8 billion years old and will continue to expand for billions, if not trillions, of years.
