Time Travel

[emuboy]

Do you ever watch TV Shows or movies with time travel (such as Back To The Future), and drive yourself mad thinking about the paradoxes it creates?

Just say for example I could travel through time, and went back to 1958 and attended the Grand Final where Collingwood defeated Melbourne, then travelled back to 2008. This would seem a simple enough proposition, but what if I enjoyed it so much that I decided to go back again 6 months later? Would I be in 1958 twice? Would I be prevented from returning? Or was I always there?

Another problem would be if you decided to go back in time and change something - as an example the Titanic disaster in 1912. If I prevented the disaster, how would I know about it in the first place? And if I failed and drowned when the ship went down, was I always there in some loop - vanishing without trace in 2008 because I had travelled back to 1912 and died many years before I was born?

Perhaps the most intriguing situation would be if you travelled back in time and stayed there. If I went back to the 1960s and enjoyed it so much that I remained in that time, what would happen in the 1970s when I was born? Would I exist twice, as an adult and as a child in the same time?

So what are your thoughts on time travel, and the problems it would create if it was possible?

What ever happens, just never sleep with your mum/grandma ect from that era. Although being a collingwood supporter...

I have vast experience in time travel, having jumped into the past on several occasions. Believe it or not, I'm responsible for the stock market crash of 1987. I was the second shooter in the JFK assassination (his leadership lead to a nuclear war with the USSR, he had to be stopped).
Oh, and I am Spartacus too, but that's a long story.

Even though there is only one reality, all objects in the universe are mutually exclusive in regards to time travel. What I'm basically saying is that if you travel say 20 years into the past and meet yourself, you will be meeting a different consciousness of yourself. You're the same person, yet seperate. The cells, bones, etc that make up your body are not the same as those that make up the younger you.

This exclusivity applies to the old paradox of "what if you killed your younger self, would you cease to exist? If so, how did you kill yourself in the first place". Because you're not linked to the future time line, but instead living in the past while committing your own murder, you will continue to exist. The future might not remember you or have any records of your existence, but you & your physical body will continue to exist.

If you have questions ask away, I have all the time in the world...

The cern collider is the first Time Machine to be invented. It is also the first Black Hole creation device which will ultimately kill us all in a few months - which is the reason no one uses it to come back from the future.

Someone has been watching too much Futurama....

Anyway, don't astronauts go slightly back in time if they are in orbit for a long time?

One thing to remember is that matter can't be created or destroyed, so the possibility of 2 beings of yourself existing is highly doubtful I would think.

Also would you see yourself there from when you traveled back 6 months earlier?

So now is there 2 versions of yourself traveling back to the same point in time from different points in time?

I've gone cross eyed.

On the astronauts, not exactly. They still go forward in time, but a slightly - barely measurable - slower rate. It is therefore time travel in a way, but hardly time reversal or TARDIS-style time jumping; more like time expansion.

It is thought by some that travelling faster than light would result in travelling backwards in time. This in itself is regarded by many as impossible, but it is only travelling AT the speed of light that requires infinite energy for anything with mass - theoretically if some quantum leap from just under to just over light speed was possible without at any time travelling at light speed; time travel would result.




As for meeting yourself, I don't see why it wouldn't be possible - except, that of course, if you do meet yourself it won't be before now. After all, its merely moving an object through a dimension, the same as moving through the three dimensions of space. Time is just another dimension, except we all travel in the same direction at pretty much the same velocity.

I'm sure those with more (i.e. some) knowledge of physics can correct this, add to it, laugh at it or whatever.

All that said, I don't think it will ever prove possible to go backwards in time; slowing down and speeding up forward movement through time might be another matter. But that is very much a personal opinion, rather than one highly evidence or even theory based.

everytime u go fast in a car that's time travel, its just so minute its not noticeable

John Titor should be able to answer these questions if he ever comes back to our time

If Time travel is true, I only think we'd be able to go forward in time.

what i have said everytime this conversation comes up, suprisingly it comes up quite a bit
