Great find, Now...
The signal started when the nearby explosion took place now it is constant and traveling away from said explosion at great speed and is broadcasting it's position.

Nice find. Sounds crazy.
Wouldn't something light years away be impossible for us to reach anyways though? It's moving fast but towards us or what?
Can't this be one of those things we'll never understand?

In that case, if we assume the radio waves traveled at or near lightspeed, it took approximately 12M years to reach us.

Einstein's theory didn't say objects couldn't travel faster than the speed of light, it only stated that objects couldn't accelerate faster than light. It may seem like symantecs, but if something is already travelling at c or faster, it doesn't need to accelerate.

I was going to make a point about that! Whatever this signal is from, it is 12 Million years old. Not exactly breaking news
Very interesting though! I don't fully understand what this signal is like, but have they discovered any sort of repeating pattern to it? Anything to suggest it's artificial?
I guess we'll find out more info after the dudes done his speech!

Same thing I was noticing.
Coincidence?

I think that both the poster who said something can travel faster than light due to relative speeds, and the one who said that something can travel faster that light, but just not "accelerate" faster are both incorrect. In the first case, C is constant regardless of relative motion, and in the second case, C is the speed limit (not the accelaration limit). No?

E=γmc2 where γ=1/(√ 1-v2/c2)
If the equation looks confusing, here’s a summary: The faster an object moves, an exponentially larger amount of energy is needed to speed it up, which is why travelling at light speed requires an infinite—and impossible—amount of energy.
So unless you’re a photon, there’s a fat chance you’ll be matching the universe’s speed record any time soon.
