Scientists Make Radio Waves Travel Faster Than Light!

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 :)

Sound waves aren't so fast though ;)
 
You don't need to travel faster than the speed of light, you just need to fold space and step through the gap, it is much simpler.

If CS Lewis could manage it with Narnia and a Wardrobe then I am sure our tops scientists are very close by now.
 
but but but but it's going fast than light! :D

The problem with going faster than the speed of light is that you need something going faster than the speed of light to propel you..

the problem with going faster than light is going faster than light :p
 
Pretty quick though, and if your half way down the stairs so you can hear both radios there isn't likely to be much in it distance wise.

Is one radio digital and the other analog? I'm sure there's about 1 second of difference between analog and digital TV broadcasts. Or there was - is analog still being broadcast these days?
 
its theoretically possible to travel faster than light (in a given medium) but not faster than the upper threshold of c.
 
Damn. I was just getting here with that question in my head, and there you are, asking it.

DAB is about two seconds behind analogue due to the need to encode and decode the signal. The same is true for Freeview. Satellite is even worse.

Front my understanding in Cherenkov the participle piles into the one in front causing a high pressure shock wave to span out in a cone just as a plane causes air to pile up causing a sonic shock wave. This then causes the medium to excite and then produce blue light.

unless you move the space around the object faster than the speed of light

im not sure exactly what you mean, in that example light travels in water slower than it travels in space, lets say the figure is 0.7 the speed of light in a vacuum, the particles travel 0.8 times the speed of light in water... hence faster than light in water but not faster than light in a vacuum
