Time Travel

Some believe dreams are the portal to past and future time travel and out-of-body experiences are relative and quite common. Sweet dreams........

Hello.

I'm new here and I hope I can add a little information.

Their are a lot of theories on ways to solve the grandfather paradox and others like it.

One is that whenever you go back in time you will do whatever you did already. That is, the act of going back in time did something which already occured, you can't kill your own grandfather no matter how hard you try because that would prevent you from being born and going back in time. It is just a law of nature. I know I am not explaining this very well but I'll try again later.

Another idea is the parallel universe thing. Someone already mentioned that universes split up when a quantume decision must take place. This theory has support in that you can't know the speed and position of a particle at the quantum level. The reason for this is that when you go to take a reading the universe splits into many where you looked at the position and got all posibilities and one where you looked at the speed and got all posiblities. Remember, quantum physics is ruled by probabilities.

Well, I hope this helped clear things up.

Hey, I'm new here too. Looks like the forum is underpopulated right now but it has potential.

I agree with Anonymous on the many-worlds quantum interpretation.

There's a set of multiple-universe conjectures on the table, too--the difference is that these universes don't arise from quantum uncertainty and may be absolutely unlike ours. For example, in the book The Bigger Bang James Lidsey mentions that other universes may be spawned by black hole singularities--essentially, such a baby universe would create a new big bang and new universe separate from ours and possibly with different physical constants. Some might recollapse almost immediately, others might contain no matter, etc.

Another conjecture, I think originated by the Soviet cosmologist Andrei Linde, posits that the inflationary epoch of the universe is actually eternal and our universe, along with a potentially infinite number of others, is a bubble of spacetime in which the 'false vacuum' state has decayed into normal vacuum. Because the false vacuum uber-universe is expanding exponentially, even though these bubble-universes are expanding also they never meet and coalesce.

Still another proposal is that the false vacuum varied across finite domains, with differing physical constants in the domains. I haven't read too much on 'chaotic inflationary theory' but it seems to involve inhomogenous inflation in finite domains of the expanding universe. Some regions would expand immensely, and others might remain subatomic. In this view our visible universe might be a small part of a much larger domain that expanded rapidly, but somewhere far far away there may be other domains with other physical constants.

Er, this really doesn't have much to do with time travel, I guess. Sorry about that.

I didnt believe in time travel until i did research on the HAARP project. Now i believe time travel to be possible through the use of wave lengths. The entire galaxy gives off a wavelength somewhere between 400-450 megahertz, so does the human dna strand. Does this mean our exsistence is just a wave length?

There is a theory that if you converge multiple high energy extremly long frequency waves in one area you can open a hole to another space time. There are rumurs that the HAARP project accidentialy opened up a hole in time back to 100 million b. c. by doing exactly this.

Well i am new here and i just saw that at one of the home page posts stated (that you mit reach a star if you can travel faster then the speed of light). Well as far as i know science has showen/hypothesize that there is only one thing that can move faster then the speed of light and they are tachyons. But tachyons only move backwords in time not forwards.

The only way science has shown that tachyons exist is that if we put a partical on one side of a room and BANG its on the other side we believe that tachyons hit it on there way back in time.
I know this throws the whole time travel theme off of my post but movies and books have given people the idea that faster then light travel is posable and it is IF u want to go back in time!!

Hope u get some ideas from this or give me some information i may have missed.

I was just looking around and i saw a ad for the Time Travel Institute and i saw a buntch of facts that i agree with like!

Logic would suggest that if time travel were ever to exist, then it already does. If time travel is possible, then the methods required will eventually be devised. Maybe it will take another 10 thousand years to discover the secrets of time travel, but if it's possible, then it's inevitable. Which suggests that time travellers are already visiting us... and visiting our past. What does that mean? To comprehend this, we must look at the many possible repercussions of time travel.

Theory A - Fate (Circular Causation) - Travel back in time to save someone's life only to discover that it cannot be avoided, or worse yet, you were in fact the cause of the person's death in the first place. This is amongst the most plausible theories.

Theory B - Alternate Universe - Travel back in time to save someone's life, succeed, return to your time to discover that nothing has changed... you've only changed the timeline of an alternate quantum reality. This theory is also amongst the most plausible.

Theory C - Success - Travel back in time to kill your great-grandfather and succeed. This theory is very unlikely since if you were to successfully kill your great-grandfather, you would inevitably never be born, and therefore never go back in time to kill your great-grandfather. Thus the paradox and the implausibility.

Theory D - Observer Effect - Travel back in time to alter history and succeed, but the only persons capable of differentiating between the reality left behind and the new reality are those directly associated with the time travel... the time traveller. The extent of the paradox rests in how the time traveller is affected. Existing "out of time", he may not be affected by whatever changes he inflicts on the timeline, thus the time traveller himself becomes a stranger in this "new" present. He may, in fact, go back in time, kill his great-grandfather, and return to the present to discover that there are no records of his own existance.

oops! I mean the human DNA strand resonates @ 1100 mhz and the human conscience window is in the 400-450 mhz band.
