An electrical field accelerates the ions to a speed of over 300,000 km/h (~185,000 mph)


Interesting, so going faster than light is possible after all? Very Happy

No, light travels that fast in a SECOND, don't you see the km/H and MPH?

light travel at 300'000 KM per SECOND

Some orbital junk arround the planet earth go near 300'000 KM per HOUR

SHIT! I'm so used to read 300,000 km/s that I always assume that it is not worth reading past the "km" Razz

Interesting, would be good to read about the other stages as well.

Also, for those of you who are interested, some scientists made radio waves go faster than the speed of light (just so no-one says nothing can go faster than the speed of light Smile):

But wait, radio waves are light waves of a lower frequency. So that means light goes faster than itself? Hmm.

I don't get the whole "nothing can travel faster than light speed" thing. What exactly is so special about 299,792,458m/s that nothing can technically go faster than that?

BTW: I'm pulling an asmcoder on you guys, too lazy to look it up myself. I'll just let you guys waste your time while I sit back : )

I think the simplest explanation I have heard is that once you get to pure energy then you must travel at the maximum possible velocity.

If there is something "higher" than energy then I guess it could travel faster but so far no one has discovered anything of such a nature.

nice pictures! i like such stuff Smile at school time i've had a job training on local semiconducter plant (unfortunatelly, it's not working anymore). i've been working in the part where transistors and triaks were produced. there was a lot of hand work, thus we (pupils) were not able to make norma, as women there were working faster then robots (and simultaneusly were talking non-stop about everything between them) Razz

I think it means "faster than the light speed as we know it", not that they travel faster than light (who says other-frequency light can't?)

Hehe, only mostly every proper physicist (and Einstein), but other than those people, no one really. Wink

Einstein did say that nothing can travel faster than light, but who says that the speed of light maximum is "c" as we know it? Wink

maybe this "c" needs adjustment Razz

c by definition is the max, that is how it is defined. And, yes, it has been adjusted at least once. It used to be 299792458.4, and later the metre was changed so that c is now exactly 299792458

You know that light doesn't travel at the same speeds in different mediums right?

They used a strong magnetic medium or something in that article -- of course then, our measurements of c might have been wrong, since we used a different medium.

It's like a fish measuring the speed of light in water, then saying that is 'c'. Then when it gets out of the water and discovers the air, it says "OMG I discovered light that can travel faster than light!". Laughing

c is not dependant upon the medium. c is defined as the speed in a vacuum. And indeed there are some media where light travels very very slowly (like 300m/s or something really really slow). I have also read about light being stopped in some very high refractive index media, apparently it is useful for data switches for things like the Internet.

apparently it's slower in the vacuum than under magnetic fields Very Happy

for me "vacuum" is a medium as well, and since there is NO real vacuum (there is at least radiation in void), then we haven't measured it exactly anyway.

We don't need to measure the speed anymore, it is defined exactly as 299792458m/s. It would be the metre length that changes to match the speed.

Actually, Einstein said particles and information cannot travel faster than the speed of light. Radio waves are a different phenomoma, and it has been proved that they can travel faster than the speed of light. I don't know all the details behind it, but they have done it.

As for changing the speed of light, I heard that once some scientists at Cambridge slowed light down to 30 cm/s.

Also as Borsuc said, there is no such thing as a true vacuum, there will always be particles no matter where you are.
