Gravitational effects also travel at the speed of light (at least theoretically), so in that case you could just watch for the supernova that'll accompany it ;)

Actually gravity propagates at the speed of light.

Damn you ninjas!

If gravity propagated at the speed of light, we'd all be in severely cold weather.

How do you come to that conclusion?

Huh.

Either way, it can't be faster than light, so actually watching the nova is a faster alternative than measuring the gravitational effects or lack thereof

I read that article like two years ago. Upon a second read-through it sounds a little... crazy.

But for the sake of continuing discussion why can't it be faster than light?

Light speed is the absolute maximum when it comes to velocity.
Quote from: wikipedia
It is the speed of all massless particles and associated fields in vacuum, and it is predicted by the current theory to be the speed of gravity and of gravitational waves and an upper bound on the speed at which energy, matter, and information can travel.
Any massless object travels at the speed of light, anything with mass would need infinite energy to reach that velocity.

and of gravitational waves
Oh, it says right there that gravity has c speed. There you go.

Dammit, there goes my plan for FTL Morse Code transmissions by jiggling a chunk of gold in deep space.

I should probably have my head checked, because I find myself in complete agreement with Nikov.

I had the same idea when I was younger. We are now idea buddies.

By the time we see it, we'll already be a million years(or less) after it due to the weird temporal stuff in space.

God, it will suck for it to be that bright for incredibly long.
But hey, I'll have an excuse for wearing my sunglasses at night.
