What the Hell Are Tachyons?

Tachyons cause a lot of problems in movies with starships, but they also cause problems for people in real life. Specifically, they cause problems for students of relativity and string theorists. Learn about the ins and outs of tachyons, and why they need extra dimensions. » 5/30/14 11:00am 5/30/14 11:00am

At last! A use for those pesky tachyons!

If you've spent any time watching science fiction shows, you've probably heard of tachyon rays, a tachyon matrix, or just free-floating tachyons. Tachyons are particles that travel faster than light. And one professor finally came up with a use for them. Sort of. » 12/27/13 12:45pm 12/27/13 12:45pm

Do faster than light neutrinos let you change the past?

There's been a lot of hubbub about the possibility of FTL neutrinos. But would breaking the light barrier really be such a big deal? Hell, yes, it would! In this week's "Ask a Physicist," we'll find out why. » 10/06/11 9:12am 10/06/11 9:12am

The problem is that for both of these things to be true, measurements of time and spaceā€¦

Faster-Than-Light Camera Records Your Future

A camera that can see almost three years into the future might sound like a crazy hoax, but here's the proof. Enitech's new Gardner Project uses tachyons to cut through space time and see 1,191 days into the future. And now you too can get involved. » 1/08/08 6:20am 1/08/08 6:20am
