Wouldn't an expansion be sort of like the effect of equilibrium? What is it that disagrees with this idea? Of a 'Big Leak' rather than a Big Bang. Does not all matter in the universe tend to reach a state of equilibrium? Why wouldn't the Universe as a whole try to do such? And I think, wouldn't Space be sort of like a container? Also Time be made of the Space/Distance within the container? (spacetime). When you add Water to a Container, the Container does not expand. When you add sugar to this water, the effect I am thinking of occurs. Do you think Life would occur without Night time? Would our sleeping schedule be the same? The way I think of time, biological clock, and the idea of physical time is that what happens if you sleep only 2 hours when you're used to sleeping 8 hours? You feel the effects of the time right? Some questions.. Hope to get some replies.
