How so?

The more we’ve understood physics, the more we’ve learnt to manipulate it – from stone tools to atomic bombs and quantum computers. If we consider time being just another vector in the 4D (or more) geometry of the universe, why can’t we manipulate it like we do with the other 3 dimensions? The rules should conform to the laws of physics.

We can perceive it, we move through it, and moving in the standard 3 dimensions doesn’t create paradoxes, so why is the time dimension special? We might not like the outcome, but that doesn’t necessarily mean the universe would break. It could be that fucking with it is dangerous to us, just as fucking with nuclear science can be dangerous, but that doesn’t mean we can’t harness its potential, right?

e: Our time machine will be found in large part within neurobiology, and especially as we merge that with biotechnology.
