Scientists Make Radio Waves Travel Faster Than Light!

interesting that you say this is the first time you've seen above topsecret when you have used it for a source quite a few times before, such as this thread on "mavity Control By Los Alamos National Laboratory"

I assume you mean photons, which have no mass and therefore can travel at the speed of light.
Anything with mass cannot be accelerated to the speed of light, as relativistic effects mean that the mass of said object increases with velocity, ending up with infinite mass at light speed.
As F=ma, an infinitely large force would be required to accelerate the object to light speed.
i think that's wrong for the situation as as if you applied F=ma all that is needed to reach light speed would be a constant force.

Indeed.
It's special relativity that postulates the impossibility of travelling faster than the speed of light, instead you get dilation of time, mass, and space.

Look up relativistic mass increases and the rest mass. F=ma from Newtonian physics, apply to Relativity. Mass increases towards infinity with increased speed so it's impossible to accelerate any object to the speed of light because it needs an infinite force.

Eh?
The speed of light in a vacuum is a constant. Light (EM radiation) travels slower than c through various mediums (water is 0.75c according to wikipedia). Therefore, you can make particles travel through that particular medium faster than light can. But never faster than the speed of light in a vacuum. See Cherenkov radiation.

this doesnt make sense
edit it does now, that sauce isnt very tasty

Bunch of non-reading retards in this thread. Stuff like this should be kept for SC.
Get to ****... that site is your bible you nut sauce.
I dont particularly understand physics but this bit made me giggle, does that make me a bad/weird person?
Well I think it's cool. I get a little confused when I have Radio 1 on upstairs and downstairs and there's a split second lag between the songs as I walk up and down the stairs.
If it's faster than light, then I guess my radios will be in sync.

No, poxy little cottage, feel like Little Red Ridings grandmother.
Dunno why, just upstairs radio is always that 'little bit' behind the one downstairs.
Probably the time it takes the radio to process the signal, they could also be at slightly different frequencies and one radio is picking up something that bounced by a different path.
You need quite a difference in distance to make any perceptible time difference though - radio waves are fast enough as they are

Cheers for that (the speed of light was obviously a pee-take), but no seriously did often wonder why the radios were out of sync.
Wasn't anything more than a second, but I'd confidentally say ½ second between the two.
But again, cheers for the explanation.
