Would you hear it?

The lights would go out in 8 minutes but which part of the sun exploding would kill us, and how long would it take?

Assuming the speed of sound is 700mph it would take 24 WEEKS for the sound of the blast to arrive, I'm sure we'd be long dead by then....... but would there actually BE a sound of the blast or a blast 'wave' at all (no sound in space?) or would it just be a case of waiting for radioactive debris to smash the Earth to bits, and how long would that take to arrive?






might have had a strange dream last night, or might not have :whistle:
 
Current theory says the Sun won't explode just balloon out, covering all planets to Jupiter. 😉

Speed of sound in space?!? :confused: :D;)

There is no sound in a vacuum, so there would be no sound. Sound is, essentially, waves or vibration that the ear interprets as sound.

The sun will eventually move from a main sequence star to a red dwarf star. Once it's fuel runs out, it is 'projected' to super nova leaving a pulsar/white dwarf star or other cosmic remnant.
 
I love all this space/universe stuff. Can't get my head round it at times.

The universe goes on for ever and ever........how does that work?!?! Surely it's like the Truman Show where there is a wall at the end? :confused:
 
I think the Sun will implode as it burns out all it's energy. So it will get larger and larger as it burns out, I believe we are in line to get consumed in this expansion, before it falls in on itself. It still has another 5.something million years to go but the Earth will be long gone before any explosion.

Here's a couple of articles that plots the demise of the sun and corrects a few of the misconceptions in posts above.

The sun is about halfway through its cycle, so another 5 Billion years left yet before it goes through the process of becoming a Red Giant, then on to become a White Dwarf. It is neither massive enough (needs to be about 1.4 times as large as the sun (or more), nor near enough to another 'star' (for either to acquire mass from the other) for any further change.

The Death of Stars - check the 'White Dwarf' reference.

I heard something on the radio the other day on the lines of...
There's 3 billion planets similar to ours in the Milky Way alone and there are around 100 billion galaxies visible using the technology we currently have out there.
Figures may be just a touch incorrect but that's the gist of it ;)

James, what exactly are you smoking at the moment? :whistle:

Slime.
 
This has to be the most depressing thread I've read, no sleep for me tonight! 😜
 
Dear thread,

What is this 'sun' that you speak of?

Yours, interested.
