but by no means claims that it IS breaking the speed-of-light barrier.





From the site:

"The speed of a shadow is therefore not restricted to be less than the speed of light.

Others things which can go faster than the speed of light include the spot of a laser which is pointed at the surface of the moon.
[...]

These are all examples of things which can go faster than light, but which are not physical objects."

So they are breaking the light speed barrier but cannot be used to transmit information since they are no "physical" even though they are "real". Or is it the other way around: that because they can break the light speed barrier, they are not physical?

Who knows. The point is that there are plenty of phenomena that break the light speed barrier but none can be used to transmit information. That is all I'm saying...
