Subject: Q&A On That FTL 'Discovery'


Hello All

Like most of us considering the pros and cons of that (maybe)
FTL discovery, was looking for a short sharp re-cap of the
possibilities and found a Q&A with Prof Forshaw (particle
physics - University of Manchester) in the UK's "Independent".

For me the (maybe) vital questions are cause/effect and temporal
integrity, and in the article the Prof allows (if the FTL
discovery is true) that cause and effect can be preserved and
'time-travel' avoided only if Relativity is abandoned. Here's
the relevant bit:

So why can't something go faster than the speed of light?

Because it would violate the laws of cause and effect. Something
could go back in time and witness the moment of its own
creation.

But these neutrinos have only gone a little bit faster than the
speed of light. Wouldn't you have to go a lot faster to do that?

No, not strictly, no. It would take a long time to get there,
because you're only going that little bit faster. You might well
die of old age before you did. But the idea is that, as soon as
you start travelling faster than the speed of light, you are
moving through time.

The idea that you could get into a rocket and go back in time is
a long way off: it is merely the theoretical possibility that
there is something that can move faster than it. We don't really
have any option but to accept that this is not possible. It's
sewn in to the theory of the universe. If special relativity is
true and something can travel faster than the speed of light,
then you can go back in time.

Does it make time travel possible?

Well it makes it possible for those neutrinos. They are the most
elusive particles in the universe. The fact that there is
something in space time that has this feature is enough to upset
the theory.

Are there any practical implications?

Well not now, but if it is true, then the law of cause and
effect is no longer sacrosanct. If you insist that cause and
effect must be true, then Einstein's theory of space and time is
wrong. The idea that anything can go back and violate the law of
cause and effect is so repugnant to scientists that they would
have to ditch Einstein's theory and find something else that
makes it sacrosanct again.

Einstein completely overturned Newton's ideas. This discovery,
if true, would be to Einstein's theory of relativity what
Einstein's theory was to Newton.
