This is some trippy azz stuff here. I've been watching it over and over and I find it absolutely fascinating....even leaning towards the possibility this COULD someday happen.
I'm a dreamer....

I watched that too and it is so facinating. Normally I don't like watching documentaries, but that kicked ***. Worth watching!!!!!!!!!!!

I cannot see time travel working at all!

It isn't about the physics of it.

Time does not move in a straight line.

It is hard for me to explain but with infinite possibilities comes infinite pathways.

As time travels it (IN THE SIMPLEST TERMS I CAN THINK OF) expands like a bubble. The pathway our particular time travels on is a point on that bubble but it moves around on the surface of the bubble in four directions as well as traveling outwards (the passage of time). If you draw a line following that dot instead of getting a straight line you get a jagged and distorted line much like a lightning strike. Unless you can trace that line EXACTLY going back in time you will wind up somewhere other than where you intended i.e. trying to fix a mistake of your past. This goes hand in hand with dimensionality where more than one dimension exists over lapping one another.

Conversely if you go foreword in time you may not be able to make it back becasue time could change from the point you left to the point you try to return enough to make it impossible for you to retrace the correct path back because of sheer probability of everything and anything happening.

I am not saying it is impossible to do it Dr. Who Style BUT by what little I know of physics it is impossible. I will just say it is unlikely we will ever perfect time travel of any kind at all. I also do not believe in temporal distortion when traveling at light speed. Einstein has been proven wrong several times over now by other gifted physicists and some very expensive experimentation!

I'm a romantic, so I would have to disagree, my friend...

1. Time travel to the past is already possible.

Conceptual time travel to the past already occurs whenever you remember a past event. While it may not be actual time travel, you can think backwards in sequences of time to a past state. Therefore, one form of time travel, a conceptual one, already exists.

2. Wormholes offer a possibility

Wormholes may allow travel to the past. It wouldn't be travel through time (more like around it) but if you have a way to survive a trip through a wormhole you probably have a way to wrap a bubble of your own space time around you, which means that you can bring a watch with you ... to time* travel to the past. Zing!

* as in, keep track of time for

3. Cosmic Strings offer a possibility

If we bend it, we can break it. If we break it, we've bought it ... a ticket to the past that is! Through time, too.

4. Science says it's possible! Unlikely ... but still possible!

Scientists can't make claims unless there is evidence to empirically support the claim. No one can say if time travel to the past is possible, though they might qualify that some methods don't work. Spinning around in a box, for example, may make you feel like you're time traveling when you're six, but clearly it doesn't work. For time travel to the past to be precluded as a possibility, every possibility would have to be tested with negative results. That hasn't happened yet.

That's all for now.

Stephen Hawking set a date and time for a time travelers party and nobody showed up, go figure. I love his dry humor.

I tried to watch it but my eyes kept getting drawn to the right to other vids... when he Rick Rolled the audience--classic!

I believe anything is possible, time-travel? Sure, but why... I'm still thinking on this... Would I want to?

Thee experience...nothing more , nothing less..
just some more adventure!

I travel through time quite often. Just the other day I watched Bill and Teds Excellent Adventure.......

GOOD POINT!

Nice thread!

Can't one be a romantic, and also have respect for evidence and reasoning?

i think it'd possible to go forward in time, but not backwards...once your in the future, your stuck there. has to do with bending space, or folding it. and forward is the only way you can go.but, along those same lines, you can stop at certain points, and do what you want, then go forward again.

Yes, one can. I was merely referring to my own predisposition.

Bear hug!

Three perhaps not unrelated comments:

Worked on a Navy ship once, many civilian techies, star trek heads all. "If you've seen it on star trek, we either have it or are working on it"

Reich and Tesla got in trouble with US Govt over electrical experiments. they were corresponding with each other.

Report from PA? coal find in a mine, 1850's?, perhaps in Smithsonium Museum?
of Coal lump with a gold chain completely embedded through it, no sign of any possible tampering. Hard coal.

Take your choice: People with gold chains were wandering around in the woods many millennium ago, or time travel is real. Both are possible.

I believe in the possibility of time travel
for one reason.
Time is measured by light.
Which is maneuverable, bendable, ceaseable,
intensifiable.
I think we can take it.

Hm. This means we must be working on Intelligent Life.

I am terribly embarrassed. But I have to ask:

Which of the above is the one reason?
