Time Travel

[Jazer]

I just watched a PBS program about the Physics of time travel. The problem with time travel is that it would involve way to much energy. What they suggest was that maybe you could send data back in time. Did you ever play the *what if* game? What if we could send information back in time. Could that change the way things are today? For example, what if we had gotten someone to the doctor a bit sooner, could that have made a difference. Could they still be alive today. I think there was a program on TV that had to do with this issue. What if we get tomorrows news paper today. What difference could we make if we had that information. I would be buying stock and making money. Perhaps some people would use that information in a more productive way to help others.

In all seriousness, time travel gives me a headache to think of in terms of real life.

I heard somewhere that the russians are working on a time machine, but also that if a time machine was created or existed then we would have seen evidence of it by now, like for example things turning up in history books of strange visitors who claimed to be from the future.

The proposed method that is the most plausible can only send and recieve things from after the machine was first turned on.

Also, I'm pretty sure we'd only be able to send things in binary, messages rather than physical objects.

Yes that's now, but if a time machine was created then it could travel anywhere in time, then in the future the time machine would be a hell of a lot more powerful and could possibly send physical objects back, the fact that none of this has really happened yet, say some random thing just appearing out of no where for no reason, means that possibly no time machine has been created yet, or they have created it but destroyed it for fear of it getting into the wrong hands. The possibilities are endless, they may have a time machine and are currently traveling through time but are leaving no traces.... Only time will tell.

Would it? How much energy do you calculate it would require?

Temporal paradoxes like these are the stable of science-fiction. Wikipedia has a large list of such paradoxes, with all the problems and proposed solutions therein.

Any one remember seeing this?

Probably not a time traveller, but still, it shows that we may be overlooking things which may or may not have happened lol.

The strange visitors were in the history books, but the Time Police have since cleaned them up, so they were never there.

I believe the theory for travel through time gives physical properties to time that do not exist.

Check out this time traveler from the year 2036. John Titor

In Hawking's TV thing from last summer, he set up a party for time travelers and would only reveal the time and location for the party after it had happened. Nobody showed

Right now they are only talking about sending information back in time. How do we know that has not already happened? New information shows up all the time and often we do not know where it comes from.

 

[Jazer]

Would it? How much energy do you calculate it would require?

They said it would take half the energy in the whole universe. WE know that time is relative. You have to get mass to travel at the speed of light and that would take a huge amount of energy.

We often meet time travelers from the future, but they then use a Neuralyzer to erase our memory.

If someone were to enter into a time warp about the best they can hope to do is go one second in either direction. So a time traveler would get to the party one second to early or to late. They have to deal with these leap seconds in order to get GPS to work.

That is what they want you to believe. Actually they just drug your drink so they can take your money when your passed out.

You are receiving this broadcast as a dream. We are transmitting from the year one, nine, nine, nine. You are receiving this broadcast in order to alter the events you are seeing. Our technology has not developed a transmitter strong enough to reach your conscious state of awareness, but this is not a dream. You are seeing what is actually occurring for the purpose of causality violation.

I don't think you can time travel backwards, only forward via time dilation. Thus preventing any paradoxes.
