Well, there are plenty of cases in which particles can go faster than light, in the sense that in certain mediums, neutrinos can pass through without interaction while photons do not. Take for instance a neutrino leaving the core of the Sun. The neutrino will leave the photosphere of the Sun before the light energy from the core will. Why? The neutrino will hardly interact, if at all, with any of the matter within the Sun’s interior, while the light will get absorbed and re-emitted. I will assume that this article is referring to the speed of light in a vacuum, however, and feel that that is probably an improvement. However, I would like to hear on the news if we can ever develop some way of moving matter through hyperspace, or something of the sort, so that we can go faster than light and visit other Stars. But then again, that’s my sci-fi/fantasy section of my brain running again!

I tend to believe that anything we can ‘imagine’ can become possible. It is what I believe God meant when he said we were created in his own ‘image’. That which he imagined, he made ‘real’. We have the same ‘power’. Most everything around you was a thought in someone’s mind, and eventually they made it ‘real’. Cars, plastic, your home, your glasses. All ‘created’ by man.

If our species exists long enough, I believe it is possible that we may find a way to travel distances now thought ‘impossible’. It may end up that our physical bodies cannot make the trip, but our ‘minds’ can.

See “Cherenkov Radiation”. High speed particles regularly enter the earths atmosphere at superluminal speeds. That is, they exceed the speed of light in that particular medium. This experiment seems to show superluminal speeds in a vacuum. Bad boys, breaking the law.. Would be a huge finding if duplicated, although I suspect an explanation will be found that does not upset Einstein.

It’s not referring to the speed of light in a vacuum:

“To reach Gran Sasso, the neutrinos pushed out from a special installation at CERN - also home to the Large Hadron Collider probing the origins of the universe - have to pass through water, air and rock.”

So, as far as I can tell, they’ve discovered nothing you can’t learn from an elementary physics textbook.

They aren't talking about neutrinos getting to the detector faster than some particular photons going through a medium. They are talking about C, the speed of light in a vacuum.
