Light

It is not actually necessary that “fine tuning” of certain parameters will have to exist in reality for proving the existence of God. I think light with its very peculiar properties is sufficient for that purpose.

There is a general consensus among the physicists that space and time do not exist for the light. This is as per the relativity theory. If existence means existing in space and time, then it can even be said that the light does not exist at all! Yes, some people have gone so far as to say just the same thing about the light that the light does not exist for itself, but that it exists for everything else. But my point is not that one. My point is that how space and time become non-existent for the light when we know very well that they cannot be so by any natural means.

Go for God

Summary: If there is a phenomenon in this universe which forever defies natural description, and if science is also found to be incapable of providing a plausible account of it based on material processes alone, then there, and there only, God can show up by proving to be necessary.

Summary: Light exists in space and time, and it is not forcibly or artificially deprived of space and time. Still space and time are non-existent for light. What is the cause of it?
