In Defense of Emergent Spacetime

My justification for writing this post is that only emergent spacetime can ultimately lead to God. So, we must defend it in every possible way.

Recently, I have posted the following in one Facebook Discussion Group:

'Physicists are now saying that spacetime is not fundamental but emergent, and it has emerged from something non-spatiotemporal.

‘As we have come to know that spacetime is emergent, so some questions arise here that I am giving below:

1) Was spacetime fundamental or emergent when the universe began to expand from the Big Bang?
2) If it was fundamental, then is there any scientific evidence in support of it?
3) If it was fundamental, how and when has it become emergent by losing its fundamental nature?
4) However, if it was emergent, would it not require the prior presence of something non-spatiotemporal from which only it could emerge?’

In reply, a person commented that we have not come to know that. It is only a possibility that only a few theoreticians are investigating. These theoreticians have yet to extend it from 3D to 4D that is essential, and until they do, they cannot even start for the possible observation that might verify the speculation.

But I think there is a reason why those physicists may not be entirely wrong who say that spacetime is emergent.

In an earlier article1, I have shown that if anything exists at all, there would be something spaceless and timeless. That is because otherwise, there will be an infinite regress. Below, I am going to repeat the same article here, but with some modification.

We can show by some simple logic that if anything exists at all, then either there will be an infinite regress or that there will be something spaceless and timeless that will stop that regress.

Now let us start from the earth. Earth exists within the solar system.
The solar system exists within the Milky Way galaxy.
The Milky Way galaxy exists within the local cluster of galaxies.
This cluster again exists within some super-cluster of galaxies.
This super-cluster of galaxies exists within the universe that contains trillions of other galaxies.

WHAT I AM GOING TO SAY NOW IS PURELY FOR THE SAKE OF BUILDING AN ARGUMENT ONLY. NOTHING IS ASSERTED HERE.

The universe exists within the multiverse that contains trillions of other universes.
This multiverse exists within some super-multiverse that contains trillions of other multiverses.
This super-multiverse exists within some super-duper multiverse that contains trillions of other super-multiverses.
This super-duper multiverse exists within some supra-multiverse that contains trillions of other super-duper multiverses.
This supra-multiverse exists within some supra-dupra multiverse that contains trillions of other supra-multiverses.
And in this way, this chain will go on up to infinity.

However, if we want to stop the infinite regress, we would have to break the chain somewhere in the middle. We would have to stop at some level.

If we decide that we would stop at the universe level, we would have to say that nothing is there beyond the universe. The universe as a whole would be neither in any space nor in any time. That is because there would be nothing outside the universe.

If we stop at the multiverse level, we would have to say that the multiverse as a whole would be neither in any space nor at any time. That is because there would be nothing outside the multiverse.

In each case, the entity being as a whole neither in space nor in time would be spaceless and timeless.

So, the entity that will stop the infinite regress will always be spaceless and timeless.

From above, we can conclude that if anything exists at all, then there would be two possibilities:
1) Possibility one: There would be an infinite regress;
2) Possibility two: There would be something spaceless and timeless that will stop that regress;

I do not profess to know whether there is an infinite regress or no such regress. NOBODY KNOWS. However, if there is no such regress, then we can say that there was something spaceless and timeless at the beginning from which everything has originated. In that case, we cannot say that those physicists are wrong who are saying spacetime is emergent.
