Can the universe come from nothing if space-time is emergent?

Once scientists have come to the conclusion that space-time is not fundamental but emergent, now many things will change in physics and cosmology. One such change is that cosmologists can no longer hold that the universe has originated from nothing.

Is there any spacetime outside our universe

From special theory of relativity we come to know that matter and energy are equivalent. And from general theory of relativity we come to know that space, time and matter are interlinked and that there cannot be any space and time without matter. As matter and energy are equivalent, so we can also say here that there cannot be any space and time (or spacetime) without energy.

Dr. Sten Odenwald has provided the following information on behalf of NASA Astronomy Cafe, part of the NASA Education and Public Outreach program:

Is there no evidence for God?

Recently an atheist has written that if there is a god and if this god affects our reality, then he would be a part of nature. So we will be able to measure the effects of this god in our reality, even if we cannot understand them. But until now we have not measured anything attributable to such a god.

But it is definitely not true that we have not measured anything attributable to such a god. So I have to present my argument to him as to why I think his contention regarding this is not true. Below it is:

Why total energy of the universe can never be other than zero

In an earlier article ‘Is the total energy of the universe zero?’1 I have already shown as to why the total energy of the universe would be zero. But there is one deep metaphysical reason that surpasses all the earlier reasons, as to why this total energy can never be other than zero.

In another article ‘Existence of anything can ultimately point to God’2 I have also shown that if anything exists at all then ultimately there would have to be something that would be neither in space nor in time, as otherwise there would be an infinite regress.

Is Multiverse Real?

In one YouTube presentation the question discussed was whether Atheism was Impervious to Evidence. The following thread is from that presentation.

No, atheism is not impervious to evidence. All you have to do is provide evidence for a god, to date nobody has done that, not even once. There has never been any testable, falsifiable, repeatable, demonstrable, concrete, independently verifiable evidence presented for any deity ever.
