@starsystem @hula @twerpling Time and space are connected, without space there would be no time. Time is a word we use for a type of pattern. The first measurements of "time" were measurements of water dripping out of a vessel with demarcation lines, or sand, or whatever. The point is that time is a measurement of things, and any measurement of any thing is by definition an abstract. There is no such thing as numbers or time, we use these things as guidepoats but they are wholly artificial. If you wakw up without a clock, and no wondows, you have no idea what time it is, because time is a unit of measurement, and if you have nothing to measure with it, no sun, no stars, then it is useless to you, thus time and space are inseparable in terms of practicality, or usefulness. You COULD in theory have time without space or space without time, but time without space is only theoretical, just like space without time would only be theoretical. If time existed on its own, it would be a kind of nothing. No particles, nothing to measure, just empty pointless duration of nothing. And space with no time would be a dead hard frozen rock that never, ever ever moves. Space and time need eachother and are inseparable. This is why you shouldn't think of time as time or space as space, but just think of them both as spacetime. If you go fast enough, you can go back in time, but the problem is that when you reach the speed of light your thrust needs to have infinite force (not possible??) to break past that barrier and go back. Matching light speed freezes time outside your warp bubble, but exceeding light speed reverses time outside your warp bubble. Idk if this answers any questions.
