THoughts on Astronomical Travel...

[Notorious_V.I.C]

If all you peoples are into time traveling type of stuff. YOu should watch a movie called Donnie Darko, unless you have seen it, if u have see it again. Its a hella tight movie

Stephen Hawking's book is great for this subject but a little tough to read. I thought most people believe time travel is not possible due to nothing travels faster than light theory? But I did hear a research department actually shot a laser through a tube of some kind of atoms and made it exit before it completely entered. There's something to think about.

Yeah, Stephen Hawking's book is a little complicated, but what do you expect..it's Stephen Hawking..lol. I think he displayed his and his peers' ideas well. A lot of research and funding for this type of science will fall into moral and ethical 'black holes' though...ahahaha...no pun intended...god i'm lame.

 

[yashooa]

i believe time travel is possible from what i've read/heard/discussed but my question is this...

if it is possible then would one person be abel to go back in time and the rest of the world stay in place, or would all time for everyone be rewound?

Being able to relate to another would probally be impossible. How would you consolidate the timelines for all of the people who are moving at different rates through the universe. It's like the problem of the twin astronauts.

Goobacks, c'mon people...nobody has seen this South Park episode?

YES YES YES! It lost its "locality."
Damn, I have an article on that experiment. I think it was performed in Italy and the particle actually passed throught the test chamber and traveled several meters across the room before it had fully entered the chamber.
I think it messed with causality a bit to. I'll se if I can find it.

Well in theory time travel is possible, well based on physics...There are three types of particles that move at or faster than the speed of light, leptons, and i cant remember the other 2 at the moment but i'll get my old astronomical physics book out and look them up. At any rate a key characteristic these particles have is that they move faster as they loose energy on an exponential curve. so when energy level reaches zero speed reaches infinity(im using the term speed losely here to cover velocity, speed and acceleration). ON the black hole question. Its not that a black hole accelerates objects to it faster than the speed of light, but rather that it promotes a red shift in the objects around it slowing the apparent travel of the objects. The majority of time dialation theory and such is based on the fact that light is trapped by a black hole, indicating it must have gravity on some level. If light has gravity than it is subject to the laws of physics and should be able to be manipulated. If/When time travel becomes possible there are 2 important characteristics to remember. A. You will only be able to observe the past and B. Though you will be able to go to the future, it will be not b/c time accelerated faster, but because you accelerated faster than the time field around you. To explain point A. say light travels at 100mph and the shooting of Kennedy has just occured. Ok well it leaves earth at a speed of 100mph. after 1hr its 100miles out and so on. Now if you were able to travel at 200mph and you left earth a half hour later, you would simply travel for 2hrs and you would be 150 miles or 1.5hrs ahead of the viewable event and thus would be able to travel to the past(observable only). Point B. is best described by time dialation...ah its so nice to talk about something other than cars...

Tachyons,I think, is another.

Donnie darko owned, can't wait till they release the directors cut on dvd.

Wow, you really know your stuff. I still have to take some physics, espsecially for my major. I just hope its not hard. I had heck of trouble understanding Chem...
Hey pimpprtege69, do u know when the director's cut is coming out? Everyone should watch that movie, really good.

 

[FrigginGLI]

Out in select cities next month, dvd who knows when. Patrick swayzee got owned hard in the movie.

 

[pr5owner]

Tachyons,I think, is another.

THAT WAS IT!!!!!!!! that was the thingy i was describing

when you have 2 tachyons the same, they affect/effect each other, you spin 1, the other one goes counter clockwise, there is no lag time to affect the other one and thats how they are suggesting FTL communications

 

[DSMConvert]

yeah its a polarity difference that causes the opposite spins....but it should be a tachyon and an anti tachyon that would creat the uber strong field....though if they ever touch hello nagasaki... v i c I too struggled with chem but physics, number theory and such was actually not that bad. its all numbers and relationships...i wrote a paper on blackhole quasar relationship in relation to travel, but Science turned it down saying it was based too much on unproven theory...darko is a greeeeaaaattt movie, but dont count on being able to think for like a week after watching it...i had a headache for 3 days after that damn movie...

I was watching the Disocovery Channel
and they had an interview with one of the leading scientests in CA (black dude, forgot his name, maybe somebody could remind me), anyway, he said time travel BACKWARDS will only work when the the time travel machine is built. It is like, the machine is a receptor from the future for any kind messages. So you don't have to worry about tourists from the future showing up right now. He also said(hypothesized), that most probably, once we get the machine up and running, we will have messages coming from the future warning us about stuff/disasters/decisions, etc.....

That sounds like a good Explanation

Also, on another note, time is just the "fourth" dimention. Once we figure how we can find it/see/sense it, we can travel that way too. but, defenitly, "time" is the "4th dimention"

I am still trying to locate the Italian chamber experiment where a particular type of particle moved faster than light.

I remember having the article marked from a news site but I can't remember which one. I just remember it was a laser shot through a tube containing cesium atoms or something.
