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:
God is not only described as omnipotent, omniscient and omnipresent, but also as spaceless and timeless. So, if there is such a God, then there would be a permanent state of spacelessness and timelessness along with the universe. If there is such a permanent state of spacelessness and timelessness, then space and time cannot be absolute. For space and time to be absolute, they should have the same values in each and every case without any exception. But if there is such a permanent state, then in one particular case space and time would have null values and in every other case they would have non-zero values. In this way they would become relative. Scientists have also found that space and time are indeed relative
.
Here comes another atheist who says that if God is spaceless, then nowhere does he exist and that if he is timeless then at no time does he exist. So if I cannot show it exists, then they have good reason not to believe it exists.
In reply I have to write to him that whatever exists within the universe exists within the space and time of the universe. But can we say within which space and time the universe as a whole exists?
And I have to explain to him in detail as to why this cannot be said about the universe that it is within any space and time. This is because although we know very well that the universe is expanding, yet as per the cosmologists the truth is that it is not expanding into anything, which means the universe as a whole is not embedded within any higher space and time. Although this universe is not within any space and time, yet for that reason we do not say that the universe does not exist.
I also gave him one thought for him to ponder over.
Thought for the day: We know that space and time are relative. But have we ever asked from when they were relative? Were they relative from the very beginning of their existence? If so, then the cause due to which they were relative must already be present there before the beginning of space and time, that is, before the beginning of the universe.
But if we say that this cause is within the universe only and not outside of it, then space and time would only be relative from the moment this cause would make its first appearance within the universe. Before that space and time would remain absolute.
But this does not convince him at all and so he says that he is still waiting for any evidence of this God. As per him even after for more than 2000 years of God-talk, still there is no evidence.
So I have to repeat to him that I have already shown how the presence of a spaceless and timeless God would make space and time relative in our universe and that scientists have also found that space and time are indeed relative.
Then again I show him how his argument that God does not exist as he is not within any space and time has already been defeated, because if it is accepted as true that God does not exist because he is not within any space and time, then for that very same reason we will also have to accept that the universe does not exist, because as per the cosmologists also neither is the universe within any space and time. And if in one case we admit that the universe does exist but if in another case we refuse to admit the same, then that will only show that we are using some sort of double standard which is not a very good thing to promote or support.
I have also shown which problem might arise if the existence of this God is denied, because in that case there would be a period during which space and time would remain absolute.
I have also written that scientists are the only persons who can specifically say whether space and time were relative from the very beginning of their existence, or whether there was a brief period during which they were absolute. However, if it is true that they were relative from the very beginning, then the cause due to which they were relative must predate the beginning of the universe.
And I have to write to him that up to this I have made my point very clear.
This time the atheist becomes silent.
So the conclusion that can be drawn from the above discussion is this: If space and time are relative from the very beginning of their existence, then the cause due to which they are relative must be prior to the beginning of the universe.
