Apparently physicists in their death machine may have found a particle that travels faster than light in a vacuum, I believe it was a hoover. All joking aside. Einstein posed that this (travelling faster than light) was impossible.



The time travel comment isnt anything new, unless they are talking about time travel into the past. Even with known physics theory technically the faster you move the slower you age relative to everything around you. i.e. if you went to the nearest star at the speed of light (Alpha Centauri) it would be about a 9 year round trip. When you got back to earth, you would have aged only 9 years, but everything you knew on earth would be long gone.



Science fiction involving FTL travel generally solves this problem by inventing "sub space".

Okay I am not a physician in any shape or form and know very little about the science. Other than "possible time travel" which my stuborn ass will never believe in what would other significant effects would this discovery have on us life forms other than possibly making weapons?



Seriously though what sort of significant effects and possibilities would it bare on us? What could we do with this?



Are we getting jet packs now?



Scientists in their "death machine" is sweet though.

I dont think we really possess the technology yet to actually do anything with these findings other than scrawl it in a textbook.

Actually Einstein's comment was that he could not conceive a something, that is naturally occurring, traveling faster than the speed of light that could be detected in a vaccum. Considering the tech at the time, that was pretty accurate. But he was confident there were particles moving faster that light in other mediums and has some unfinished formula's attempting to prove it.



Neutrinos have been long suspected to be able to travel faster than light based on their behavior.





In any case, cool stuff IMO

But even Einstein suggested there was some form of communication between entangled particles and the change communication that we cannot detect was instant regardless of distance, therefore it was faster than light. He called it Spooky Action at a Distance, it is known today as quantum entanglement.

I wouldn't call quantum entanglement as a sign of FTL communication. In the world of the very small the notion of locality breaks down. Particles are "smeared" all over the place, it could even be said that there are no single particles at all, that it's just merely different interactions of forces that can then be measured giving them their properties.

As for the news, it's interesting, but I'd wait for more experiments to confirm it before re-writing any physics books.

My favorite teams
  1. Portland Timbers
  1. Chicago Blackhawks
In other words, someone basically found a tachyon, right?

But doesn't this prove that science is just a theory, as infallible as the bo... oh nevermind wrong thread

Maybe but there has to be some form of communication between the two particles and the changes are instant. So the information is traveling instantaneously as far we know

There is no such thing as instant, only smaller reactionary times. And possibly so small that they are not measurable by any instruments.

I'm just waiting for when any of this shit can be applied in a practical sense. I mean, we can't even move at the speed of light yet, and we've known about it forever!

If we are going to explore the universe, we need to get some tech upgrades going. And soon...

We must construct additional pylons.

They may not have to rewrite anything. Neutrinos may not have any mass or negative mass, which means they can do whatever the **** they want.

I agree. I didn't think it would be possible.



He is sposeda be on 60 minutes sometime this year. Last I heard, the piece they filmed is sposeda air late November, early December.
