Of course i am not done looking around about breaking the speed of light and such, but going back to where this topic began, howstuffworks.com, found this: http://www.howstuffworks.com/news-item6.htm

I think it will probably be replaced by another piece of news soon since it has a general name, so here is the thing. I'll edit it out or a mod can if they think it is a waste to paste it in the post.

"Once thought to be unbreakable, the speed of light as set by the laws of physics has been exceeded in two recent experiments, according to a New York Times news report. The speed of light in a vacuum, or empty space, is 186,000 miles per second. Exceeding this speed jeopardizes the entire theory of relativity, which rests on the idea that light speed is the universal limit to how fast anything can travel.
Scientists have found ways to break that speed limit. In one experiment performed by researchers at the NEC Research Institute in Princeton, N.J., a pulse of light was sent through a transparent chamber filled with specially prepared cesium gas and was pushed to travel at speeds of 300 times the normal speed of light. The light travels so fast that the main part of the light pulse exits the chamber even before it enters. Theoretically, this means that you could see a moment in time before it actually takes place.

Researchers at the NEC declined to comment on the experiment while it is under review by Nature, a weekly peer-reviewed science journal. However, Kazuko Anderson, a spokesperson with the NEC in New York, confirmed the accuracy of the New York Times report.

In a second superluminal study, published in the May 22 issue of Physical Review Letters, scientists at the Italian National Research Council of Florence shone light beams at a curved mirror. The mirror then shot the beams back at the instrument that measured the rays' speeds. The beam coming from the center of the mirror was measured at 5 percent to 7 percent faster than light speed. The authors said this effect only works over relatively short distances, such as the one meter used by the Italian researchers.

Exceeding the speed of light may have future implications for space travel and computer chips, but for now scientists are uncertain about the practical use of this discovery. Neither experiment was able to use a light beam to carry any information or prove that an object of any weight would be able to travel beyond light speed."

I've seen that before. The speed of light was not exceeded though. I did a little more research than you. Go here to see why the speed of light wasn't exceeded.

Quote:
I don't think it negates free will. To me it seems like this, months ago I had a choice of doing my homework or not doing it. Whatever decision I made, I had free will then. Looking back on it, I might wish I had of chosen differently, but it already happened. So let's say you went back in time to do something, before you went back in time you didn't know you were going to do it. So in the loop of what you did you had already done before you went back in time etc. All theory, but i like it because it makes sense.
Doesn't make sense to me. If you go back in time in the same timeline, but can't alter anything, then you don't have free will. Even if you think you do.
Quote:
I am sure there is evidence supporting the theory that nothing can accelerate past the speed of light or it wouldn't be considered common knowledge, (I plan to search around for it after I make this post), but I have never seen any of it so i am not sure. Also, how do we know we aren't already moving that fast? The universe is expanding, but do we know if it isn't also sliding as a whole. If it were going faster than the speed of light then maybe light created would go faster and since it is relative, we think of us as still, then it would appear to be light speed. Like I said, i haven't looked into this much yet, so that could have a few holes in it.
OK, the universe can't be sliding, because by definition the universe is everything. There can be nothing for it to slide in, or towards, because there's nothing "outside" the universe to move relative to. The concept of outside the universe doesn't even make sense.
But there are some "holes" in the theory of relativity. For example the speed of light barrier is only local. You could theoretically (if you had enought energy) warp space around you and make a warp bubble. Just like star trek. Within this bubble you would be moving slower than the speed of light, but the bubble itself would be moving, so from an outside point of view, the speeds would stack and you'd effectively be moving faster than light. Look up the name Miguel Alcubierre.

I think that they would all steam from the same beginning but each one is a single variation which changes it from then on...like the difference between this universe and the next universe might be me hitting backspace. And then if that were true then maybe if you went back in time you would actually be shifting universes if you could change something and went forwards in time.
I may be wrong, but I think there was actually a startrek(next generation) episode based on a theory like that. I know it is a TV show, but the theory it presented was pretty interesting. For every decision you make in your life, 100s of new paralle universes developed, each one based on how the world would be if you made a different decision.

I just finished reading some of the links on quantum computing that were in this thread and one of the 100s I found on google.

If you want a good explination of quantum computer, I found this to explain it well, and simply enough for me to still understand

http://www.cs.caltech.edu/~westside/quantum-intro.html

There are articles like hosted by almost every major university out there. I like this one becuase it is cross referenced well.

From what I understand, quantum computing could have to do with parralle universes, then again it may not. It is all based on superposition, where a qubit( quantum bit) is no longer restrained to just 1 or 0, but could be 1 and 0 at the same time. It's easier to understand if you follow the experiment given in the article. Depending on what quantum theory you believe this could be acheived in various ways, however the multible universe theory is the most widely excepted from what I have read so far.

Here are a few more good links

Thanks for the link explaining the other article on breaking the speed of light thing. I guess i should have phrased what i said differenty; i don't mean all the universe, just what we know of it, all the galaxies and things that supposedly came from the big bang. Since the universe is supposed to be infinately big or whatnot, there could be other things we don't or may never know about in the universe. Sorry for wording it wrong. I still don't like the idea that you are only moving if it is compared to something else. About it negating free will, i guess it is all in how you look at it.

One thing i think would be really interesting, is traveling to a different dimension (universe, whatever) where there are completely different laws of physics and all that. I think there are alot of things we still can't explain, so maybe in a different universe they would be different.

Religion and Science is a bit deep for me SR,
(Yes I belive in god)

But I belive in the possibility of time travle. I mean why not. Man has made the impossible hapen time and again. But I do agre just by you going back you would change things. Just thrusting matter back in time would cause change. And if you moved anything or did anything, talked to anyone, I belive it would cause a fork in time. 2 time lines, call them demesions if you want. But I think it would be the same demession just one after the change and the one you lived.

Personaly I do not belive anyone should ever do it. Not to see if a person on trial realy did it, or even to just check things out, or to get rich. You never know what you could change.

Just to butt in real quick . . .

As for the argument over dimensions or universes, i think it is pretty obvious what someone means when they say alternate dimension. Let's not nitpick. Unless by alternate universe you mean another universe that is physically far away from here but i thought the universe included everything.
The missing word is parallel. Par and several other people have used it, so you all mean the same thing. It's parallel universes though.

And check out some stuff by Michio Kaku and superstring theory. Superstring doesn't directly relate to this (though dimensions-wise it does), but it's interesting nonetheless, and Michio has written extensively on multiple dimentions/parallel universes, though how many of these are online is unknown to me.

Think of things like this

::puts barret on::

I could choose to go and [censored] my neighbors wife, and I could choose not to, two different descisions, in some lifeline i would have done the one, and off of that i would have gotten caught and i would have not gotten caught, and from that and normal time that i see as normal now it'd be totally different but the same only with that descision.

Everything happenes, its just how do you want it to seem to the you you think you are smile .

Isn't superstring theory an effort to create the unified theory( aka theory of everything)? I remeber reading an article by him on the net once blue, I will try to find it again and post a link up. Superstring theory--a world based on vibrating strings existing in ten dimensional hyperspace--all seems a bit silly when you say it like that.

Haha, I knew I would find it. It was real hidden though. Who woulda thought he would host articles he has written on his website. Hell don't these big scientist people know that you are supposed to hide all the really good information on some obscure FTP server.

Anyway, there is alot of other stuff he has written there too.

At first I was in agreement, but then I thought about it more, and now I'm not so sure. (Maybe I should keep thinking first).
If no-one ever does it, then how would we know for sure that it works, or what it would really be like? Also, every decision we make changes things all the time, and we have no idea how what we do is changing the possible outcome of things. How do you know things woouldn't turn out for the better? Besides, it's an alternate universe. It has no effect on the timeline you came from, so it's not like you'll disappear if you kill your parents.

I prefer the term alternate to parallel.

I have some books by him. Good stuff.

Yeah, pretty much. M-Theory is more advanced though. Look that up.

it's a sign of a organized, efficient, and analytical person. My dad is the same way, I also do that to a smaller extent.

I know this is an old post, but I didn't want to start a new topic on something I think relates to this.

I heard that theory awhile back that our universe keeps expanding, then when it slows down to a stop it is pulled back together and the opposite of the big bang happens. (i think that is what the theory is)

So i was thinking, what if this happened over and over again and it would be like the different dimensions each time. I guess that would be the same physics and everything. So then traveling between dimensions could actually just be time travel, going a certain amount of time to the next or previous cycle. So i guess this would mean there are infinate cycles that happened the exact same, i mean if it is random then that means it would happen eventually and if it goes on forever then they would all have infinate clone cycles.

Paragon, i think it was, said that the theory that each dimension is just one detail different from another is pretty common, so i think this one probably would be too.

Quick question, I didn't want to comment but it was based on time and space...

Theories are just that, their ideas that are ideas until proven correct or wrong.

The universe always does expand, i mean look at black holes, etc, think of them like "babies" etc...

I'm half asleep so if i sound like a moron ah well...

But its doubtful that it'd be able to just go back in time to visit alternative universes since say you went and sluged your mom in her stomach, there would be many alternative universes for that, there'd be one where you didn't hit her, one that you stabed her, one that you shot her, one that she went to the hospetal, one that she shot you, etc...

It'd be nearly impossible for ALL of those to be avalable in a timeframe that it didn't happen..

well on the subject of time travel id have to say that if you go back in time and u do something the end result would be the same becasue it was meant for you to go backin time and do whatever you did. in thus the present would remain the same.

please exuse me if im not making any sense being as i too am 1/2 asleep

Another theory alot of people don't know about, is the one about how if you went back in time to change the future, nothing would change because what you did actually caused what you wanted to change to happen.

actually i think someone might have posted this before....
