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.
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.
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.
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.
