FYI and discussion

[Husker24]

The only thing I can think of would be to find a way to travel faster than the speed of light with a powerful telescope and look back on the earth as it was in the past. Other than that I would say its impossible, but what do I know im just a factory worker.

I'll have to replay my copy of "The Time Machine" (2002, starring Guy Pearce and directed by H.G. Wells' grandson.)

I already posted this article tomorrow.

What if you flew in a giant circle and returned to Earth? Then you wouldn't need the telescope.

For the telescope thingy, you could just send them up in various positions to catch the light as it went by. Different distances would be different times.

But I'm just a factory worker too....

Merry Christmas

If it's possible to build a machine to travel back in time, then where are the time-travelers from the future? Maybe they're investing in the stock market.

[mikrofon]

This is well illustrated in the film Bill & Ted’s Excellent Adventure.

'Glad to see the article referenced well-noted technical sources....

I already posted this article tomorrow.

LOL and I've already read it...

Time is only linear in the observer's plane of reference. To travel to alternate times, you must change refernce planes - whether through quantum changes (physical) or through the learned skills of the yogi (mental). Remote viewing is an example of mental time travel (in which you cannot interact with the past, merely view it), and there are some references to humans who have the capability to co-locate or teleport through space/time.

If time travel is possible, then it already exists. Once it is developed in any time period, past, present or future, it is available to all time periods via the time travelers. It is not time-dependent.

"According to this theory, time runs slower for a moving person than for someone who is stationary."

ie. . .the 'physics of boredom' or the 'time flies' theory; when you are busy. . .

"If it's possible to build a machine to travel back in time, then where are the time-travelers from the future?"

Maybe they don't want to 'come back'...

I know nothin' about this stuff. But I sure hope somebody figures it out soon. My Dad died when I was 7. I'm 58 now. I would cherish a day visiting with him. There are so many questions I'd like to ask.

On the other side of the spectrum. Traveling at warp speed is something I am keenly interested in. I currently have a 2 hr commute and it just sounds so tempting to walk out the front door and in the blink of an eye to have arrived at my destination.

[Michael Barnes]

If time travel were possible, we would see abnormalities at catasrophic events (9/11, Pearl Harbor, Nagasaki -although at a distance ;) - etc.).

Personally, I don't believe in the barrier of light. I believe our understanding of physics has not yet reached a point where we can control how we manipulate matter when approaching (or passing) the sped of light.

As far as the "time machine" inventions, well, whose to know if one hasn't been invested in some far off future and not already been used? None of us here would KNOW if world event's were altered by a future presence. It would all seem like history as normal for us.

[BJungNan]

Wow are these guys stupid, I just got through traveling in time. Geez, some people are absolutely clueless.

[fella]

Time travel is no big deal.

I've been doing it for a little over 56 years now, just hope I can keep going.

[Old Professer]

Bookmarked for later.

Not necessarily. One theoretical type of time travel only works if you have a "receiving station" operating in the "destination" timeframe. So from any point in the future you'd be able to travel back into time only as far as the first invention of time travel, but no further.

Same here. Every now and then when I've had one too many I find myself reliving my life over and over.

[Koblenz]

If time machines are possible, why haven’t we built one?

I think a better question might be: if time travel is possible, then why haven't we been visited from the future yet?
