Our most accurate models predict a limit and all experimental evidence ever collected demonstrates it. Faster-than-light travel is also a logical impossibility as information traveling faster than light creates paradoxes which can't be resolved.

The lightspeed limit only applys for inertial referemce frames, aka IT ONLY WORKS WHEN YOU ARE DEALING WITH SPECIAL RELATIVITY.

In noninterial reference frames it is possible for objects to travel at any fucking speed. It is called "General Relativty". Read a book dipshit.

Is that supposed to be a counter argument? Take a water hose and let the water flow out at 10 m/s, then turn around, surprise, the "water dot" may be faster than 10 m/s. That principle holds even in relativity.

Oh, right. With matter it's going to be impossible. I mean you could use an electron beam, but then there would be more than one electron involved.
(Also, everything is matter for me, the difference is more like massive vs. non-massive.)

How so?

Go on a train, travel at 200 m/s.
Walk at 10 m/s forward.
Voila, you are now traveling at 210 m/s.

Travel at speed of light, c.
While traveling at c, turn on flashlight.
Is the light from the flashlight traveling at 2c?

I don't believe that shit about the pointer on the moon.

You described something else. In your example, the person is on the train himself. The train is boosted to almost c, then the racecar starts, that's another boost. Two boosts together are always another boost (slower than c).
In my example, the observer (the one with the laser pointer) is at rest; he doesn't transmit any information from the left side to the right side of the moon. It is true that he transmits information to both the left and the right side from his point of view, and that information is indeed limited to c (just like any information, which is a fundamental assumption of SR). However, the part that is faster than c doesn't transmit information.

Hmm... alright.

So what if... I have a big stick. Instead of a laser pointer. And with this big stick, I touch the left side of the moon... and then the right side.
Does the end of the stick travel faster than c as well, like in your laser pointer example?

YOU ARE FAIL JOSEPH! AMERICA MADE YOU RETARDED!

In any reference frame you measure the "local speed of light" as c. BUT YOU ARE NOT ALWAYS MEASUREING THE LOCAL SPEED OF LIGHT FUCKTARD!

If you are in a gravitational field (say a planet), and you measure your local speed of light it will alwasy be "c".

If you make a meaurement of the speed of light of light closer to the planet, it will be less the "c".

If you measure the speed of light of light futher out is will be greater then "c".

Don't you remember Einstiens equation for the change in the speed of light as a function of gravitational potentials?

>>	Anonymous Mon Sep 5 19:30:38 2011 No.3691960 >>3691857 That's bullshit. Even if you moved your hand at the speed of light the maximum speed the dot has is the speed of light

>>	Anonymous Mon Sep 5 19:30:38 2011 No.3691963 locally, no. but if you could warp space somehow, then you might be able to cross a great distance faster than it would take light to cross the same 'distance' had you not folded space.

Not really. Which question do you think Einstein asked himself or his colleagues if not "do you personally think <something about science>"?

Sure, they had a far greater grasp of the topic we're discussing here, but that simply means we're giving half-wrong answers or opinions.

Sources/Dervations that the speed of light is varible in general relativity:

1) On the Influence of Gravitation on the Propagation of Light', Annalen der Physik, 35, 1911. A. Einstein (Equation 3)

2) The Meaning of Relativity', A. Einstein, Princeton University Press (1955).
(Equation 107)

3) Relativity, Gravitation, and Cosmology', T. Cheng, Oxford University Press (2005). (Equation 3.39)

the stick is a physical thing and can't go faster than light for a variety of reasons
simply, the stick is made of atoms, the atoms interact through mediating particles that can't go faster than the speed of light
besides that there are still the energy requirements from relativity
