Recent articles in Scientific American have talked about traveling faster than light.

Einstein's special theory of relativity predicts that nothing can exceed the speed of light. But special relativity applies when spacetime is flat. When spacetime is curved, the theory applies only "locally"--that is, over regions of spacetime small enough to be considered flat. Consider the analogy of a plane that is tangent to a sphere. The flat geometry of the plane is a good approximation to the geometry of the sphere when the size of the plane is very small compared to the sphere's radius of curvature.

The Only Begotten Son of God-Jesus and His Created Servant Angels can travel faster than the speed of light!

No Problem!!!

Yes, now we just have to build starships that can do that - and use them to deport the liberals. ;)

I see the regulars on FR have just about left this behind due to graduation from amateur science 101. Goedel proved that we can travel anywhere in time, and that means time is an illusion. We're just not looking at it right.

Not to be a skeptic, but on this one I will have to see it to believe it. I'm hung up with the whole infinite mass issue.

While I have no problem believing you can travel faster than light someday I must observe that scientific american also had an article recently blaming the start of global warming on the first ancient farmers to the present day humans............

I read about an interesting about a test in the UK a couple of years ago where researchers were about to slow down light using various gases, the side effect of the research proofed that the exact speed of light is not a constant and can change given the enviroment it is in, gravity can also bend light.

Thus since the speed of light it not a constant, traveling faster than it is possible in theory. But the more interesting research is in using high-powered laser looped on themselves to created a wormhole in space/time for time travel and space teleporting.

I didn't say where I would prefer sending them.

I was thinking a one-way trip to the galactic core. After all, like attracts like so they should be able to find a convenient black hole; if not in the center, then close by...

It may well turn out that trying to travel that way will be akin to going from New York to Beijing by tunnelling through the planet.

That is an illusion. Too bad we can't use the math they use in physics these days to make nice easy pictures. Just imagine that space can be bunched up like a rug so you can step one step and find yourself at the next star or the next galaxy immediately. That's one of the easier images.

Guth did it. To create a solution by using mathematics as a convenient porthole is not the same thing as the discovering the absolute truth. If there was one big bang, there must be another, and so it goes.

We've known for quite some time that light slows down while traveling through various media. That's the reason for refraction in water or glass, for example.

I haven't heard of anything that increases light's speed.

There is a new book, Incompleteness: The Proof and Paradox of Kurt Godel -- by Rebecca Goldstein. About $15. Biographical with philosophy, written by a philosopher. Good writer, too.

Pioneer is leaving the solar system at a faster-than-expected rate. One speculation is that light may be faster than established out there, making interstellar travel that much easier.

No, we're still looking at it wrong. If another fearsome threesome like Goedel, Einstein, and Heisenberg ever come into our midst again, maybe they'll be able to furnish us with the right spectacles like Rowdy Roddy.

Well, I can give you something right now that travels much much faster than light, in fact it appears to have infinite speed; Gravity.

The planets react to the instantaneous position of other planets even though the time for light to travel between them may be hours, days, weeks or months. If there was a lag in the reaction because of the light speed, many planet orbits would fly apart in spirals. Funny, nobody make a fuss about this because it has always been this way.

We have seen some people try that. They don't seem to go anywhere and they are still there when they recover from the toxicity. If they recover.

No, flat spacetime speed of light is the issue here.

Not about subjecting it through gasses.

A fork travels through a chocolate cake faster than the speed of light. Think about it.

Not necessarily, however, there is an experiment being conducted in space at this very moment that should be able answer this conclusively within a year or so.

I hate to be a wet blanket, but...

Ever have a bug hit your windshield as you're tooling down the highway? Of course you have. A minor smudge on the glass, and that's about it.

Now, ever have a rock kicked up or tossed out by a semi strike your windshield while cruising at freeway speeds? I have, a couple of times. Chipped or Cracked glass, possibly worse.

Sadly, empty interstellar space is not all that empty. I for one would NOT want to be in a vehicle moving at 93,000 miles per SECOND that was going to hit anything larger than an occasional hydrogen atom. That's just at 1/2 lightspeed, where there are NO theoretical problems at all!

Assuming someone develops some sort of really cool, nigh invulnerable shielding, then at a minimum, what you have is the re-introduction of aerodynamic drag and "wind" resistance, and your energy consumption just to maintain a constant speed increases exponentially.

No, the only way you are going to be able to cross interstellar distances is with either a slow boat generational ship, or with the "warping" of space, essentially folding the distance to bring your destination "closer" to you.

"The Only Begotten Son of God-Jesus and His Created Servant Angels can travel faster than the speed of light!"

Does that mean they have no mass? Otherwise, to reach the speed of light they would by extension attain infinite mass which would destroy the Universe.

I thought Goedel was the guy that proved that in any well defined system there will be things that are true which cannot be proven.

Long, long ago, in 1922, Louis DeBroglie published his theory of MATTER WAVES. They were subsequently discovered at the Bell Labs : we're HALF waves as well as particles : MATTER WAVES or the "wave function" as obliquely referred to by physicists(hoping you'll get ElectroMagnetic waves confused with MATTER WAVES). Thus the formula : E=mc^2=hw where h is the quantum and w is the "wave number". DeBroglie's formula for the maximum velocity of MATTER WAVES is U = c^2/v. Relativists went ballistic upon hearing that MATTER WAVES travel FASTER than the speed of light(c); thus the "cover story" of phase and group waveforms(pure nonsense to cover their behinds), and cosigning DeBroglie to "crazy aunt alice" status. How often do you hear MATTER WAVES discussed by physicists? Thus by n/0=n and nx0=n(division is repetitive subtraction, n/0=n-0-0-...=n ; and what is 2x3x0? thus nx0=n+0=n), thus it reduces to E=c^2=w. Thus FTL has been there as the foundation of quantum mechanics since the beginning. Analogy (to a jet plane): locally v=0(everything within is in a pure momentum state)and globally moving at c^2, covering 1 light year in 105 seconds....

It does no such thing. The theory *assumes* that nothing can travel faster than light. The rest, like E=MC2, comes from that assumption.

No every claimed the speed of light is constant, regardless of the media it is traveling in. What is claimed is that the speed of light *in a vacuum* is the same for all observers, regardless of relative motion. Some aspects of super-string/twistor theory seem to indicate that the speed of light, in a vacuum, *should* be changing over time.

Does this portend that the gravity-caused curvature of spacetime must be canceled in order to travel above light speed?
