he, he, ...... well to me it seems that my Super 8 films catches the photons all the time.....;)

but that imaging method is stunning every which way.....


shoot....

But can they catch faster-than-light particles?

Following a three year study experimental physicists at CERN recently posted what they believe is evidence that neutrinos are traveling faster than light.

Many well known theoretical physicists have said that if that is true (and it remains an "if" until further independant tests are done) that the laws of physics will have to be rewritten.

But that is actually rubbish. The laws of physics won't have to be rewritten. If you look at the theory of relativity there is nothing in that theory that says particles can't travel faster than light. What the theory prohibits are particles accelerating across the speed of light (in either direction). Particles born at a given speed don't accelerate to that speed. For example photons are born at the speed of light. They don't accelerate to that speed. The same would go for faster than light particles. They are just born at that speed, avoiding violation of relativity and therefore any need to rewrite relativity.

The reality is that until now (should it be true) nothing has ever been measured going faster than light. What would have to be "rewritten" is not the laws of physics as such, but entrenched assumptions about those laws.

An interesting side effect (should it be true) is that such particles would need to be regarded as traveling backwards in time. Apart from various groundless conjectures there is nothing in the laws of physics that would prevent this. And from an experimental point of view there is nothing about the experiment (should it be true) that introduces any time travel paradox.

The neutrinos simply arrive earlier than the photons.

The reason for regarding them as traveling backwards in time has to do with the fact that the speed of light is a constant. This hasn't changed. The speed of light remains a constant. Irregardless of the frame of reference in which light is measured light continues to be measured as traveling at the same speed (the speed of light). So if we measure particles traveling faster than light we have to speak of them as taking a small amount of negative time to reach their destination. So it is of more a theoretical formality, than sense shattering significance, that (one would say) they travel backwards in time.
