also, just because there's time and space doesn't mean there's "people".
sure, time is only "truly" meaningful when observed, but it's also entirely relative.
How do you measure time if you're floating through space, and not adhering to any one singular solar cycle?
Does time simply cease to exist, speculatively, until you end up at a new variable location?
Regardless. Time doesn't actually matter. It's times mortality which does.
Ironically though, time's mortality isn't a measure of it's own, it's a measure of ours.
When we die, we don't weigh time down with our wanton need and want, and desire for recognition.
Time simply exists until the next entity to perceive it comes along, becomes sentient, and begins to scare itself with observations of it's own fragility once again.
