Another article about time travel. I like thinking about it being a possibility at some point. After all, if you went back and told the Wright brothers that most planes would weigh about a zillion pounds, be shaped mostly like a cylinder and be made out of metal they would have told you no way is that going to work.

There's a couple of reasons why time travel will never ever work....

1. See point number 2
2. Refer to answer 1

I rest my case!

It might be because I just watched Catch-22 yesterday but this made me chuckle.

Nice to see some humour in here, those posts made me laugh.

If time travel was possible the gunman on the grassy knoll would never have got a clear shot at JFK for rubbernecking time travel tourists swamping his pitch (sorry if in bad taste but kind of proves the point)

Forward time travel is possible, just go very fast.

But what if, in this time line we did go back and stop the killing, and therefore create an alternative time line (that we can't access) where he started world war III and killed everybody on the planet?

It might happen..... in the future.

Best leave it alone. :devil:

Even if we did know the future, wouldn't we change our behaviour and so change the future, and if we change the past then it's always been the past so why bother?

There are "designs" for time machines, but the caveat is you can only go back to when the machine was turned on. Also it has to be a spacecraft, because it would be at the location of the event you wanted to see, and the entire galaxy has moved away from that point. Which basically makes it useless without warp technology to move from point to point of the past events.

So, no.

Until they come up with an alternate theory. This is changing all of the time so I sincerely doubt they KNOW for certain.

No, you miss the point. It was actually LHO who shot JFK from the Book Depository. But the time traveling tourists got in the way of him making the shot, so a future "time operative" had to travel back to correct the flow, and the only clear vantage point was the grassy knoll...

Now did i get that right? (http://www.goodreads.com/quotes/369785-one-of-the-major-problems-encountered-in-time-travel-is)

Time Travel is not possible because "Time" does not exist.
Time is not an Attribute but simply a unit of measurement,
a way to help define the act of Traveling to and from points in space. :alien:

Yeah, if you think about it, it's a totally ridiculous idea, gravity and physics would have to reverse itself so that the milk can un-spill itself back into the bottle. However it does make for interesting stories. You sort of have to dispel 90% of known science to write good science fiction, otherwise it's just stories about space missions. Even 'Gravity' had to alter facts to tell a story that had no aliens or anything strange.

And I would be one of them. That's the first place I would go, but I'd have to make a couple of trips just to be able to watch ALL the gunmen.

This reminds me of two movies. "Primer" is well known (I watched it 3 times and still didn't get everything) (there are countless sites trying to explaining it with charts) but there's another less-known one, also done very low-budget, which is amazing story-wise and well told. It's Spanish and really worth to watch: "Los cronocrímenes" http://www.imdb.com/title/tt0480669/

If time travel to the past was possible in the future, we would never know, because from our perspective our history would be in effect from the moment something had been changed. How would you know if Adolf actually succeeded in world domination first time around...

We won't know, until we can access those alternate timelines. ;)

Who knows. Maybe the first step would be to try something like in that movie Frequency.

http://www.imdb.com/title/tt0186151/

I seem to remember a scientist at NASA saying something about how our communications with our Apollo missions might still be floating around out there somewhere. Of course that's not the same thing that we are talking about here, but it could be some kind of stepping stone if we found a way to tune them in again.

It's not just Apollo communications - ALL radio and TV that we've ever produced is "out there" heading away from Earth. Of course they get fainter and fainter as they travel, but with a sensitive enough receiver... If we could go FTL and get ahead of them, we could listen to them from the beginning. Then again... if we could go FTL... ;)

Here's the best video I've found about quantum entanglement....


https://www.youtube.com/watch?v=dEaecUuEqfc

In short, it won't work. It seems taking a reading will re-entangle the particles, so far so good, but when you check the other particle, you will re-entangle them again!

It would be a great sudspace radio. It could work as a telegraph with a single set, or by using 16 sets, some low fidelity voice transmissions could be sent. it would probably sound like early internet radio.

"In short, it won't work"

not yet, but who knows what new stuff they figure out 300 years in the future...


Even if we did know the future, wouldn't we change our behaviour and so change the future, and if we change the past then it's always been the past so why bother?
good point.

some also think it would make the person go back in time to a parallel timeline, or parallel dimension.
so it might seem like everything is going according to the plan, but in reality the person is only changing an alternative version of the world. so even though he/she fixes the problem in world-1, the problem still persists in world-2.

also, it would be sad to take away the good things that happens as a consequence of a bad thing...

i think you might get stuck in a loop here.

fixing stuff with time travel... it only works in "The Terminator"

it´s easy to travel, here´s some inspiration...though fixing things didn´t work out for this guy either, not matter what he did in changes of the fabric of time/space, the death of his wife just took on different ways to her final destiny.

I kinda accidently broke the speed of light once.
Luckily I had a tube of Crazy Glue handy, fit it all back together and walked away.
So far nobody's noticed, so I think I'm good with it.
