Will there ever be any physical explanation for 'X', if 'X' is not physically real?

In a debate between Dr. William Lane Craig and Quentin Smith on March 22, 1996 Dr. Craig has thus given a theistic notion of God in his opening arguments: "a personal Creator, uncaused, beginningless, changeless, immaterial, timeless, spaceless, enormously powerful, and intelligent."

Here it has been mentioned that God is spaceless and timeless. Not only in the three major religions originating from the Middle East, but in the eastern religions also God has been repeatedly mentioned as spaceless and timeless. Actually the two most common attributes of God that can be found in various religions throughout the world are his spacelessness and timelessness. Now by very simple reasoning it can be shown that the existence of a spaceless and timeless being in this universe implies the relativity of space and time. We say God is spaceless and timeless, which means for God space and time are non-real, non-existent, whereas for us human beings they are very much real, existent. So if God is really there, then in that case the same space and time will have two different values for different beings: For God they will have null values, whereas for us human beings they will have non-zero values. So if God is really there, then in that case space and time cannot be absolute, because for those two to be absolute they must have to have the same values for everybody. Thus the presence of such a God will make space and time relative, and science has also shown that space and time are indeed relative. If this reasoning is correct, then I think that there is no justified ground for discarding mystical experience as a mere hallucination. This is one point.

The second point is that if God is really there, then in that case there will be a permanent state of timelessness in this universe, because we say God is timeless. God does not exist will then mean there is no such state of timelessness. God does not exist therefore means no need is there for science to show how a state of timelessness can be reached or attained, because there is no such state in this universe that requires an explanation from science. But despite that science has shown how a state of timelessness can be reached, because in special theory of relativity it has been shown that at the speed of light time totally stops. If there is no state of timelessness in the universe, then why was it at all necessary for science to show as to how that state could be reached?

If the scientific community throughout the world thinks that this timeless state has no physical reality, then we can put the following question to them: “Will there ever be any physical explanation for ‘X’, if ‘X’ is not physically real?”
