Anyone think time travel exists?

Easy, I’ve already tried it.

No

I'm sure Joe Biden does.

To believe in time travel you'd have to believe that the past and the future actually exist. They don't. The past is gone, the future isn't there yet. There's nothing to travel to.

Don't be half a fan. If you're going to quote from the movie, get it right.

"Easy. I've already looked into it for myself."

I am a REAL Napoleon Dynamite fan!

Yes, I just got back from yesterday.

time travel to the future is absolutely possible through time dilation. Time travel to the past really isn't even theoretically possible.

Relative to a being on the planet Zirkan 4, I'm dead; relative to a being on Fiklotrva, I haven't been born yet; relative to you, we're in the same slice of present "time."

We are all traveling through time right now. That’s a fact.

In a sense, all we do is live in the "past." The moon we see "happened" 1.333 seconds ago, the sun 8 minutes ago, and so on and so forth. When I look at my wife, it's her microseconds ago.

We're just stuck in a block of spacetime. Our lives have already been lived. There is no free will. We're just going through the motions of experiencing "time," which is just an illusion of how we interpret entropy.

Then on the quantum level, this block of spacetime branches off into many worlds (see Everett). It gets even weirder.

It's all hard to wrap one's mind around. I struggle with it daily.

Agreed. It's been calculated that from an inertial frame reference, the rate of travel is approximately one second per second.

I think I'm going to travel to tomorrow tonight. I'll tell you all tomorrow what it's like when I get there.

Do I think its possible to send a human back to our human past and experience it? No.

But has someone else pointed out, there are indeed elements of time travel possible, depending on how you define it. Time dilation being one, but we lack the technology to accelerate something with a human in it to the required velocity.

There are also theories in quantum physics regarding "many worlds" and "determinism." Think of it this way, if laws of physics are immutable and we understand them entirely, and each particle (down to quantum levels) behave based on those laws, and if you know all attributes about them, then you could argue that we are doing only exactly what the initial state at big bang has determined we will do. You think you are deciding to run or not today, but only one of those options will be true, so to speak. This ties in with philosophy and the idea that no one actually has free will.

What if our future self has stalked us before, but in a location they know we won’t see them. They can’t actually meet with us either because theoretically our whole existence/timeline would be eliminated. Got me thinking like crazy after watching some crazy videos on the Tube. I know I’m not the only one out there. Someone else blow my mind right now

Human lifespan is around 84 years on average.

Even if you were born today, the technology for time travel is so far advanced that there’s no way it would be developed in a way for a large living organism to safely do it within the next 84 years.

So no, none of us on this forum will ever have a future ‘self’ observing us.

Time is simply a different dimension for each individual. Time only exists if you possess the ability to compare the presence and absence of events.

Absolutely.

Greg does that time travel thing all the time, to get back to his 20ies gloryness of running a 8k.

We are traveling through time every second of every day.

Time travel does exist, just not in a physical conscious world you know. As you must understand there is no such thing as time, only waves of outcomes, for which each human creates. You will never understand this as your mind cannot conceive this. Nor are there any words to explain it.

Very interesting proposition Ryan. I suspect that one's future self can meet with one's past self and if one were to remember such a meeting, attempting to alter it or prevent it, would cause one's reality to separate off into a different plane of existence. In fact the past is quite mutable, and with subtle changes to it, the future can be shaped. Each change will create a new plane of existence (there an be infinite) with only the actor being able to distinguish between them. With the actor being 0, it is possible to create a scale to measure divergence from 0 (the initial course of history the actor remembers). Thus when meeting oneself, no paradox is created, things can both happen and not happen. Its useful to have a destination in mind when travelling through time and instrumentation to measure the travel to this point.
