So what you guys think is it possible to travel faster then light ?That we will be able someday to travel throu space , explore other solar systems and galaxies ?

It is impossible for anything with any mass to even reach the speed of light, let alone pass it

yea, I think there is a way around this little theory. Just need some smart guy/gal with a clue on what that is to come around.

Edited by: Imperator Jora''h on 22/12/2009 08:14:51 You cannot go faster than the speed of light (or go at the speed of light). Period. It's the law man!
There is no way around this. A few things happen when you reach the speed of light (if you could) which flat out prevent it.
Notably as you approach light speed your mass increases. If you reached light speed your mass would be infinite. All the energy in the universe cannot accelerate an infinite mass.
Also, time slows down for the traveler as they approach light speed. At light speed time stops. So, even if you could reach light speed once you did you would never turn off your engines before the universe itself came to an end.
That said you can get arbitrarily close to light speed and for the traveler, since time slows down, the trip may not take long to them at all. To us waiting on earth it would take thousands (or whatever) years but to the traveler might just be a few minutes or days. Consider the Oh My God Particle:
Quote: v = 0.9999999999999999999999951 c
So taking 3+10^8 metres per second as the speed of light, we find that the particle was traveling 2.9999999999999999999999853+10^8 metres per second, thus 1.467+10^−15 metres per second slower than lightùone and a half femtometres per second slower than light. If God's radar gun is slightly out of calibration, this puppy's gonna be doin' hard time for speeding. After traveling one light year, the particle would be only 0.15 femtosecondsù46 nanometresùbehind a photon that left at the same time.
Object Distance (light years) Perceived Travel time Alpha Centauri 4.36 0.43 milliseconds Galactic nucleus 32,000 3.2 seconds Andromeda galaxy 2,180,000 3.5 minutes Virgo cluster 42,000,000 1.15 hours Quasar 3C273 2,500,000,000 3 days Edge of universe 17,000,000,000 19 days
Thus, if you could accelerate yourself to the speed at which the Oh My God particle was traveling, you'd be able to travel to the edge of the visible universe in a couple of weeks. Unfortunately, even assuming you found a source for the energy it would take and invented a means to accelerate yourself and Intergalactic Vessel Omega Point to this velocity, you wouldn't get far before being disrupted into subatomic goo due to interactions with photons in the ubiquitous cosmic microwave background radiation.
So, pretty messed up for us when it comes to stellar travel. Possible ways around this (if they exist at all) would be Warp Drive (ala Star Trek) which does not require FTL in your local reference frame, Hyperspace or similar travel through a different dimension where distances are much shorter or Wormholes which provide a shortcut point-to-point.
All science fiction so far but one can hope.

Time doesn't slow down for the traveller as time is relative, to him the time in the rest of the universe will speed up (or to an observer of the traveller will slow down in time).
From what I remember of my physics its possible to travel at the speed of light, you just need to accelerate instantly in order to get there, which given the laws of physic is extremely difficult (I wont say impossible because its over used and usually wrong) to do without some shortcut (like warping space or hyperspace).
Travelling FTL is like any physics constant it can be broken under the right conditions. Conservation of energy is another one that most people think is a constant and can never be broken, but on a quantum physics level it can be broken for an infinitesimally small period of time.

I don't think it's possible to travel faster than light, but it's not outside the realms of possibility that we may find other ways to travel vast distances; maybe warping space, artificial wormholes etc etc
I wish I could believe that I will see some of the above in my own lifetime, but I really doubt it.

I won't try to say anything really complicated, because even if you know it or not, you still come off like a jerk ass.
I think tommy lee Jones put it best:
"Fifteen hundred years ago everybody knew the Earth was the center of the universe. Five hundred years ago, everybody knew the Earth was flat, and fifteen minutes ago, you knew that humans were alone on this planet. Imagine what you'll know tomorrow."
Also, the law's of physics are not something that you hold as sacrosanct and fear the change off. They are there as a mathematical means of prediction. They are not meant to trap or enclose our ability to understand. I have a paper I co-authored coming out soon here, I'd post it if anyone was interested, but the finding's would have been impossible if we strictly stuck to what people previously had laid down. That is the nature of progression though, should something prove inadequate, it must either be improved upon, or discarded so a working example can take its place.

Can't say I know much more than extremely basic mechanics but following the simple F=MA formular would it not be impossible to decelerate from light speed even if you acelerated instantly?

Macroscopic tunneling maybe? Getting from one point in space instantly to another one and skipping the space between. Guess the issue would be to have all sent out particles assemble again at the destination the way it was sent of and not as a incoherent cloud of subatomic particles. --------

The thing is that our entire modern model of the laws of physics is based on the speed of light being constant and insurmountable (because Einstein pointed out that Time was a lousy universal constant). That said, I'm quite sure there are ways around it.
Unless someone manages to disprove c as a universal constant, there will be no acceleration up to and past the speed of light. However, I hope that we will eventually find a shortcut method to overtake light. -----

Edited by: Rainus Max on 22/12/2009 11:33:52 You cant use F=MA whilst travelling near the speed of light, pretty much every value in that formula goes out the window. As you approach light speed mass and time tend towards infinity and length tends towards 0.
Its all so fun.

Thats what I was thinking mass = inf so to decelerate you would need inf*A force resulting in minus inf force

Fart is FTL easily
They say Thought is faster than light or at least similar But when a Fart is coming, I think to withhold it yet it is expelled before I even finish my thought
Yup future is smelly

Thats right but at the speed of light it doesnt work
Wiki probably explains it better than I can, its been years since I covered this lot.
to quote wiki again "To accelerate an object of non-zero rest mass to c would require infinite time with any finite acceleration, or infinite acceleration for a finite amount of time."

That is a fallacy, and wrong. I don't really know what "people" thought, but from what I know of our knowledge of physics back then, there was no theory that stated one could not travel faster than sound.
Regardless, just because traveling faster than sound is possible, it doesn't imply that traveling faster than light is also possible. They are completely separate things and have nothing to do with each other.

Actually, as I recall it, there's nothing in the maths to stop you going faster than light, only from going as fast as light. Oddly enough, once you exceed lightspeed, your "kinetic" energy actually decreases in symmetry with the increase from 0->c. The lowest energy tachyons are the fastest.

A difference without a distinction.
Sure the traveler's clock technically keeps ticking but what does that mean? To the traveler the entire universe around them will instantaneously evolve essentially out of existence. A billion years, a trillion, a gazillion years...it's all the same to the traveler. No matter how quickly the traveler tries to turn off his engines there will be no universe left. He is stuck till (if) time itself along with the universe literally cease to exist no matter how long that may take. So, as a practical matter, time has stopped for the traveler.

Travelling FTL is like any physics constant it can be broken under the right conditions. Conservation of energy is another one that most people think is a constant and can never be broken, but on a quantum physics level it can be broken for an infinitesimally small period of time.
No information can be transmitted FTL. Matter = information. So does a signal saying who won the World Cup and so on.
That said you can make "things" go FTL without violating anything. For instance shine a bright light on the moon from the earth then pass something (on earth) in front of the light really fast. The shadow on the moon, if done right, could be seen to travel FTL. The shadow is not a tangible thing though and no information is being transmitted FTL so there is no violation.
There is quantum entanglement in quantum mechanics which does seem to transmit information at FTL speeds (basically instantaneously). Einstein did not like this and called it "spooky action at a distance". This has been experimentally verified though. However, we cannot exploit this for FTL communication. The universe still conspires to disallow that (more's the pity).
IIRC quantum tunneling may also exceed light speed.

Is it possible? There's probably a way around it.
Will humans achieve it? Not at the rate we're going. We need to commercialize space exploration.. until we can convince the world there's profit up there, we'll be stuck down here. ♥
