ok...so...the fastest speed is that of light right? what would happen if we could go faster than light......?

Question

and then we go much faster and faster what would happen? time will stop? and faster...time will go backwards??? where is the law of the physics here??? we will dissaper? open a warpwhole? open space?? or its just IMPOSSIBLE something or what ever , could go faster than light???? being light the fastest speed in this universe. believe it or not someday we are gonna be able to go back in time.

Answer 1

light has nothign to do with time. no matter what the sicentists say, that whole concept is illogical.

lets take this to an extreme. lets say you have a ship that has the ability to circle the entire planet a billion times for every time it rotates once (one day). you then do it. you go around a billion times. much faster than light. vawla. you just did it. a bilion times in one rotation. there is my point. the earth only spun once, one rotation, one day.

just because you can get to china before a light molecule doeent make time go fast or slow. you just out ran that molecule.

if you can circle the earth entirely in one single second, nothing hapons, you start at point A, circle, stop again at point A one second later,,,, that second passes.

Answer 2

There was a theory somewhere, I can't remember were. That actually there are particles that go faster then light called Tachyons. But the problem is that they cannot slow enough to be as fast as light. Otherwise they would have to write the light theory. Also according to the theory of relativity and the famous e=mc squared the faster you go the more mass you have. If you somehow reach the speed of light your mass would be infinite.

Answer 3

Eeeeh, not easy to answer this. If you're interested in real time-travel theories I highly recommend Steven Hawking's book: The Universe in a Nutshell. He goes over several theoretical ways we could travel back in time (but in the end, non of the theories turn out to be viable - tough luck). As for the fastest speed being light...that's not strictly true either. Tachyons theoretically exist that can travel faster...but it gets complicated for non-physicists.

Suffice to say that no one knows of a theoretical way to travel back in time (that we know of). Going faster than light isn't viable either...matter is converted to energy as it approaches light - I'm afraid there wouldn't be much left of you as if you made the attempt ;)

/edit: (and aimed at Jamie below). Light itself does not affect time - but there are physical laws governing speed. You really need to read up on relativity - it's not possible to explain it all here.

Answer 4

Well I had a dream or vision I was in a space ship of some kind. The windows had display information about the area of space I was in. I was slowing down and passing through the outer rings of the solar system when my ships flight computer announced it was switching to inner planet systems view. I guess I was going about warp 75 while I was slowing down. I saw a time/space anomaly moving toward the earth about 96*10^5 light minutes in area.

Answer 5

A direct result of special relativity (that all frames of reference observe the same speed for light) is that the faster you go,
- the slower time goes
- you get thinner
- you get more massive

So if we tried to accelarate a grain of sand to the speed of light, it would eventually get so heavy that it would require more energy in the universe to accelarate it to that speed (since heavy things require more energy to accelarate). Hence, we will never go the speed of light.

There do seem to be ways to beat a photon in a race, but they involve taking "shortcuts" through warped space (see general relativity).

Answer 6

Insofar as I know the basic postulate of the Theory of Relativity is that the speed of light is constant with respect to the observer. We express our declining ability to observe something as its velocity approaches the speed of light with
L = Lo√(1 - v^2/c^2)
This means that as the velocity of an object approches the speed of lightwith respect to us, it appears to become shorter in the direction of travel. The object does not, in fact, become shorter, as can be verified by an observer traveling in the same direction with the same velocity.

The same can be said of the infamous mass equation, M = Mo/√(1 - v^2/c^2) This equation simply states that as the velocity of an object approaches the speed of light with respect to some observer, it becomes more and more difficult for that observer to affect its motion, until, finially, at lightspeed, the observer cannot affect its motion at all (as well as being unable to see it). Again, an observer traveling in the same direction at nearly the same speed will observe no relatavistic effect, and Newton's Laws will appear to hold for that observer.

The time dialation equation is T = To/√(1 - v^2/c^2) states that time appears to elapse more slowly as someone approches the speed of light with respect to the observer. Note the reciprocity of this observation. for observer A, observer B's time is elapsing more slowly, but for observer B, observer A's time is elapsing more slowly. In actuality, there is no difference in the passage of time for either.

The key word in all three of these is the word appears. All 3 equations have solutions for v > c. We just shy away from trying to explain the implications of those solutions. If you plug v = 2c into the equations, you get
L = Lo√(1 - 4) = Lo √-3 = jLo√3
M = -jMo/√3
T = -jTo/√3

And no, none of this can be construed as making "time travel" possible.

Answer 7

you won't be able to return and forth speedier than the value of sunshine. is this this form of complicated theory for individuals to entice close? Can they no longer additionally draw close the incontrovertible fact that there is not any such factor as a tachyon? Time return and forth to the destiny is obviously obtainable and we do it for all time. in case you choose for to pass far into the destiny then you definately might wish a spaceship able to vacationing close to the value of sunshine. in accordance to relativity no cloth merchandise, an merchandise that has mass (photons, mild, don't have relax mass) can return and forth at or above the value of sunshine. This in basic terms happens to be a form of quirky little issues with regards to the universe we are residing in. And it in basic terms happens to be probable the main examined concept in physics on the grounds that general at each and every particle accelerator lab interior the international human beings use those arithmetic to artwork out how briskly a particle would be going if pumped as much as distinctive energies. And that new factor in switzerland will crank relatively some potential into despite that's they are accelerating and that factor will nevertheless be shifting at under the value of sunshine. human beings have concern with this using fact they are purely used to speeds that are a tiny fraction of the value of sunshine and hence no longer familiar with what happens once you return and forth at close to mild speeds. no remember how lots potential or how many engineers you have engaged on it you will in no way return and forth speedier than mild.

Answer 8

You would have to do some sort of matter conversion because all mass has a terminal velocity. You can go very fast and exceed the speed of sound but light is another issue.

Answer 9

The fastest speed is that of light. End of story.

Answer 10

I think its sumthing to do with time goes slower when u r in sumthing that is going @ the speed of light or faster
