Just including space, time and energy, but no matter?
Can you? Energy must act or move, which makes space necessary, and change in state means that time is necessary.i second answer no, because once you have space time and energy matter is a given.
but, i can easilly envision a kind of existence where there is no time, space or matter, but just energy.
Given that the universe looks headed towards a heat death, then the answer seem yes.Just including space, time and energy, but no matter?
