This might be a stupid question, but is time linear and only moving along one direction in Buddhism (i.e. past to future in a straight line)?
I've been thinking about this for a couple of days now. If you are living now, when you die, could you be reborn at a point in the past? Or back into the present? Or is rebirth only consecutive? I was imagining what would happen if, for example, a meteorite hit the Earth at some point in the distant future and mankind was obliterated. Would we all then be able to be reborn back into earlier points in time repeatedly until eventually achieving enlightenment, or would that be that..?
What do you think..? Again, apologies if there's a really obvious answer to this that everyone here already knows.
