Is time travel Impossible Because time Doesn't Exist?

[Edwardo Piet]

Because they don't exist anymore?

Circular reasoning.

Ummm. No. No reasoning required. The premise is that the past doesn't exist anymore by definition. We can't visit something that doesn't exist.

I don't "assume" time travel is impossible. I UNDERSTAND that actual time travel is impossible. Someone could move through space and say space and time are one, and then say they are "travelling through time" but to suggest they are time travelling as in actually visiting a time that is by definition no longer existent would just be utter bullshit and an equivocation.

And the whole point is science can't touch this because science only deals with how we experience the world, it deals with phenomena as opposed to noumena. Science never does and never has dealt with objective reality because it can't even prove objective reality. And unlike what many say, science doesn't even have to assume objective reality. Science merely has to assume that we experience a shared world and it collects evidence of our shared experiences. Science by definition can never know "whatever is out there outside of our experience" because science only tests what we experience. All the theory and mathematics is based on empirical observations, and the tools we use require our own senses to operate. And all the calculations are calculations regarding our experience of the world and not the world itself.
