A guide to time travel.
This community is serious; not intended for fan fiction or parody.
What we normally think of as time travel isn't yet possible, but discussions of the physics, rules, constants, and possibilities will be productive as we work out ways to make time travel a reality.
Discussions of science fiction, imaginings, myths, and hoaxes are not productive and don't belong here.
This community is dedicated to the pursuit of time travel as a science, not chasing down myths and hoaxes. Please constrain your posts to the realm of physics, mathematics, ethics, practicality, and related subjects.

What if (lemmy.ca)

What if life naturally evolves towards time-travel as it begins to understand the geometry of the universe? What if the way to travel more than one direction in time lies in our ability to perceive time in the first place? That’s biological, universal, measurable, and therefore quantifiable – and so far, most things we can quantify, we can manipulate.

You're in deep Paradox Land here!

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.

What if humankind’s ultimate evolution is to eventually evolve into “God”, which we then use our power to create a new universe and seed this new universe with life that evolves into humankind again, except the new universe is really the same universe and we’re evolving into “God” again, but we’re stuck in an endless time loop of creation and destruction.

Our concept of gods being really limited and ego-centric, I guess sure. But that doesn’t seem sustainable over the long term.

e: also, I’m talking about physics and geometry, not physiology or sociology. Those are generally relevant, but not in this context
