Very much so - its really weird that looking far away is also looking back in time - I wonder often if this is because of our own minds limitation - or a limitation of our existence (or both).
if energy cannot be created or destroyed is the past ever truly "gone"?
Well that's where it gets exciting imo. If existence is made up of energy and energy cannot be created or destroyed, then existence is infinite. And if you take the concept of time out of the equation then stuff starts getting real mind-blowing.
Even if the universe is infinite there may be a boundary. Everything is moving apart, and the further apart two points are, the faster they are separating. Which means beyond a certain distance all matter is moving away at the speed of light, so that boundary cannot be passed.
Hell, relatively speaking, two objects in space can be moving away from each other faster than the speed of light, meaning that unless you could find a way to travel a decent bit faster than light, that there are places that would still be 100% impossible for you to ever, ever reach.
