Part I
Two reasons can be given as to why an entity may be spaceless and timeless:
1) Reason A: If the entity is not within any space and time, then it will naturally be spaceless and timeless. We can also say that it will be spaceless and timeless by default;
2) Reason B: If the entity is placed within some space and time, and if it is forcefully deprived of space and time, then also it will become spaceless and timeless.
For 1), we can give the example of the entity from which our known spacetime has emerged. In this 21st century, physicists are no more saying that spacetime is fundamental; rather, they are saying it is emergent. Spacetime is emergent means the source from which spacetime has emerged cannot be within any spacetime, for the simple reason that there cannot be any spacetime prior to its emergence. So, not being within any spacetime, it will naturally be spaceless and timeless. However, physicists are describing it not as spaceless and timeless, but as non-spatiotemporal. Whatever may be the nomenclature, the concept remains the same in both cases; the source from which spacetime has emerged is not within any spacetime and so, it is naturally non-spatiotemporal/spaceless and timeless.
For 2), we can give the example of black hole singularities. Earlier, it was known to us that black hole singularities were point-like. Now it has been known that they are not point-like but rather one dimensional ring-like. In case of black hole singularities, whether they are point-like or ring-like, space and time almost contract to zero due to a tremendous gravitational force.
Now suppose there is one more entity within the universe that is also spaceless and timeless, but for which neither Reason A nor Reason B can be thought of as its cause. Here I am speaking about light. Light is within the universe, but as per SR both the travel distance and the travel time become zero for light. So, within the space and time of the universe, light occupies zero space for zero time, which is tantamount to saying that light is spaceless and timeless.
Can we say that light is spaceless and timeless due to Reason A? No, we cannot say so, because we know very well that light is within the space and time of the universe.
Can we say that light is spaceless and timeless due to Reason B? No, we cannot say so, because we are not aware of any force that is active in case of light causing space and time contract to zero for light.
If light is spaceless and timeless neither due to Reason A, nor due to Reason B, then what is the reason due to which it is so?
Moreover, no black hole is as big as the universe. So, the length that is almost contracted to zero in case of black hole singularities is nothing compared to the entire width of the universe. But for light, the entire width of the universe is contracted to zero. If a tremendous gravitational force is responsible for the contraction of a black hole’s size of length almost to zero, then which force is responsible for the contraction of the entire width of the universe to zero, in case of light?
Does anyone have a clue about it? Can anybody say what the cause is due to which light is spaceless and timeless?
Part II
I have already stated that we do not know the reason due to which light is spaceless and timeless. But, whatever may be the reason of this, it can be shown that this reason cannot lie within the space and time of the universe.
Let us suppose that X is that reason and that X is within the universe. If X is not spaceless and timeless itself, then it is not possible for it to make another entity spaceless and timeless. So, X must have to be spaceless and timeless first, and then only it can make another entity spaceless and timeless. But, if X is also spaceless and timeless, then we will have to ask the same question about X that we were earlier asking about light: Being already placed within the space and time of the universe, how has it become spaceless and timeless? So, now we will have to search for the cause due to which X has become spaceless and timeless. Therefore, from this we can conclude that the cause due to which light is spaceless and timeless cannot lie within the space and time of the universe. It must lie outside any space and time.
The only entity that we know of that lies outside any space and time is the source from which our known spacetime has emerged. The existence of this entity in nature has already been confirmed once physicists have declared that spacetime is emergent. So, here is one entity that is spaceless and timeless by default, and for which we need not have to seek any further cause due to which it has become spaceless and timeless, because we already know that it is not within any space and time.
Now, if scientists can somehow show that this lifeless, mindless, and unconscious entity but that happens to be spaceless and timeless simply by default, can NATURALLY make another entity (aka light) spaceless and timeless, then this universe WILL NEVER NEED ANY GOD.
However, if they fail to do so, then only we will be compelled to posit some sort of consciousness here, because it is possible for a conscious being only to know how it is spaceless and timeless.
Science is the ultimate arbiter of truth and so, let science show that there is a natural explanation here.
We will be waiting for that explanation.
