Relativity is serious bidness.

Did someone or several someones disprove the FTL neutrino?

I haven't read the official write up, but there were several critiques, including the amount of energy the neutrinos carried when they hit the detector, and possibly the relativistic effects from the satellites not being accounted for.

They'll run it again.

I also heard there were plans to run an experiment between Chicago and Minneapolis, but I haven't heard anything in a while.

Nothing can travel faster than light in a vacuum in a given region of spacetime. Einstein made no claims that it wasn't possible to have faster-than-light velocities between two isolated areas of spacetime. As long as the speed of light in each spacetime isn't violated, the spacetimes themselves can be moving relative to each other at any velocity in theory. The trick is to structure the spacetimes just so.

I don't get it.......:confused5:....Is anyone making money off that chit yet ?

No. We need to do a things like develop massively more powerful energy sources and do a lot more physics before we'll be zipping around faster than light. I would say that if it were possible for a spacecraft the size of the USS Enterprise to go FTL, the power source would be in the neighborhood of the output of the entire world's current yearly energy production per second.

Well then, who wants to be the next Bill Gates ???(not the dead one)...:D

But will they take off from a treadmill?

186,000 miles per second.

It's not just a good idea, it's the law.:D
