What goes faster than the speed of light?

Question

I know there is nothing we know of that can go faster. But, I was watching something and they said something about an atom, or somthing like it that was able to go as fast as it wants, but it can not go slower than the speed of light. I can not remember what it is called, do any of you know.

And no I am not making it up, it was on The Universe on the History Channel. It is not neutrinos. Also it said it was a Theroy, and they thought about using it for space travel.

Answer 1

try a search on "Tachyon" and then a simple experiment... look at Sirius, now glance upwards towards that next bright star upper left, Procyon.

SOMETHING... call it what you will, imagination, thought, awareness, just went 5.2 lightyears in a second.

that's pretty d**n fast.

Answer 2

Some scientist have a theory that the Universe is expanding faster then the speed of light, powered by dark/matter, or dark energy. It is becomeing more excepted in the scientific community as a main stream theory.

Answer 3

Hey i watched that same thing, but sorry i have no idea what it was?  Some sort of energy that didn't exist like matter??? i have no Idea!

Answer 4

As per the theory of relativity there is no particle that can be accelerated to approach and then exceed the velocity of light. For it will require infinite energy, the mass of the particle approaching infinity. However, as per some physicists, if in an interaction, a particle is born with a velocity larger than that of light, it can continue to travel with a velocity higher than that of photon. Such hypothetical particles have been named 'tachyons'. This possibility has been  theoretically calculated (including Sri Sudarshan, an India born physicist), I do not know if these have been observed experimentally.

Answer 5

Nothing that we know of for sure but there are theories sayin thing about wormholes and breaks in dimensions. h**l that ere has to be another way considering how fats Ufos can go. id say break in dimensions or somthin along those lines

Answer 6

You're thinking of tachyons.

ohhh right gigaty gigaty goo (quagmire)

lol sorry had to pop that joke in:)

Answer 8

There is a theoretical particle know as tachyon (you might have heard it from science-fictions like Star Trek, and such), which does move faster than light itself - resulting in very odd properties of it, like that it has a complex number for its weight (meaning if you multiply it with itself, the result is a negative number).

But the existence of tachyon is yet to be discovered.

Also as you said, tachyon can not go slower than the speed of light, because that particular speed (299,792,458 m/s) is a 'barrier', nothing can cross it - or at least, as we know it today.

Answer 9

After three years of a university physics major I have not heard of any particle that goes faster than the speed of light.

The one thing that did go faster than the speed of light was the expansion of the universe itself during the big bang.

Answer 10

I asked a question similar to this a short while ago, and the question was does space travel faster than light?

And I got a whole lot of answers saying yes, mostly because the universe expands faster than light.

So my answer, the universe itself.

Plus the theory of tachyons and negative mass.
