Has the sun exploded?

Omg the sun just blew up!?

Hi guys, has anyone seen the sky recently, looks like the sun just exploded

omgwtf Earthquakes?

hmmm sky looks kindy dodgy... I know, I will go and ask the forum, they will know how to fix this

OcUK: Spec me a sun

To be honest, by saying the sun exploded, you will find that many on here won't notice, as we are on here so much, we have forgotten what colour the sky is!
 
I wonder if we'd even notice that the sun had exploded, since surely we'd be dead about 2 milliseconds after we realised it had.

Don't think an explosion could travel faster than light, and it takes light a few minutes to reach us :confused:

Wasn't talking about the explosion, I was talking about the radiation / UV rays frazzling us all. And yes, it'd take light a few minutes, but obviously we wouldn't realise it had happened until the light had reached us, and since UV is light and as such travels at light speed, we'd probably die straight away :).
 
It would take about 8 minutes before we would see it happen.

That is the speed of light.

What is the speed of gravitational force? If the sun were suddenly "removed", how fast will the absent gravitational wave travel at?

Not to mention if it really did explode, then you may get those strange quark interactions where you can affect counter particles instantaneously, regardless of distance.

It will travel at the speed of light according to General theory of relativity.

This was checked a while back experimentally
