Thanks for this. I’m no physicist but you hit the nail on the head for me. I believe time is an illusion; the past is a memory and the future is an imagination. We only live in the moment. Literally, everything, everywhere, all at once. Mass, too, is an illusion; mass is energy, and energy is an unsubstantial force acting upon other forces creating the illusion of mass. I think Spinoza was correct. The universe is one substance with infinite attributes of which we are aware only of two: Thought (energy) and extension (matter).
