Time travel

[ABikerSailor]

Actually.....time travel IS possible. People do it every day when they re-visit memories of stuff they enjoyed.

Alzheimer's patients do it, but they don't have control over it.

But........that's just rudimentary time travel. Kinda like learning to crawl. Work on it long enough, and really cool stuff will happen.

Read "Jonathan Livingston Seagull" by Richard Bach for reference.

Time Travel. It's a cornucopia of disturbing concepts.

Think of this; you go back in time and cause your own demise. You upset the timeline in such a way that you no longer exist. Poof you are gone. But now that you are gone in the future, you can no longer go back in time to upset the timeline. So do you magically reappear?

Well if you went back into the "past" and disturbed something a new timeline would branch off. You would not effect the current timeline.

I don't believe in visiting the Future
because it hasn't existed yet
but I do believe in returning to a point in time
which already occured.

Well i mean there is a theory that if you travel at light speed around the world when you get back to where you took off you will see your self taking off again. Im almost positive that it was Einstein's. But im not positive. But overall, everything is a theory. It's just a matter of belief or not.

I think you have the right idea. According to special relativity, time would seem to pass more slowly if you traveled to some distant star and back at an incredibly high speed. If you spent seven years on this journey, for example, you'd theoretically return to earth to find that more than seven years elapsed there in your absence. Both of these measurements would be accurate, because an observer's perception of the passage of time is dependent on their velocity.

Yes. That's the right theory. I don't think a space program has figured out how to travel at speeds with out breaking down the human body.

Actually, studies have revealed that the farther you are away from Earth (farther up out of the gravity well), the slower time goes. The farther away you get from the gravity of the Sun, the slower it gets yet.

Time/Space continium has quite a bit to do with the 4 forces, gravity, magnetic, strong polar attraction, and weak polar attraction.

You're speaking of general relativity. You're mostly correct, but it's the other way around. Time seems to go more slowly at a point of lower gravitation potential. That is, the severity of time dilation increases with proximity to massive bodies. Seven years spent in the vicinity of something more massive than earth would translate into more than seven years on earth.

In my post, however, I was speaking of time dilation in special relativity. Because the hypothetical ship in my last post accelerates and jumps inertial frames when it turns around, the person on it ages less than the person who remains on earth because the second person stays in the same inertial frame and is not traveling close to the speed of light.

I'm betting it will take thousands of years for us to produce spacecraft that are capable of traveling at any significant portion of the speed of light. I guess you never know, though; a breakthrough may be right around the corner.

Of COURSE what we call "time" exists. Good GRIEF.

You are alive right now. Some day, you won't be. The "in between" is what we call "time." It exists. And you should make use of it.

You would probably enjoy a novel called "Replay", by Ken Grimwood. It's basic premise is to relive the same life multiple times with the small changes the main character makes to his life causing new results each time.

There is no such thing as time travel other than one's experiencing the passage of time from the present to the future and the remembering of times gone by...except in the movies.

Likewise, there is no such thing as a perpetual motion machine.

Beaming of live organisms from one place to another will never occur.
