When you watch large fireworks on the 4th of July, the light from the explosion reaches you very quickly, but the explosion itself typically remains far up in the sky. There is a significant difference between the light that illuminates the phenomenon and the unfolding phenomenon itself.

No chance of that. But I doubt you're doing your brain any favors by hanging out at GLP or the other site linked at the beginning of the thread you referenced. That "hiddenmeanings" site is pure meaningless mysticism.

Here's some real information.

Who said this? (quoted from the GLP thread) Someone over there has a brain.


Quote:
SN1987A is 170,000 light years away. The light from the explosion has been seen since 1987 meaning the super nova occured sometime around 168,000 B.C. Any materials cast out are moving at sub light speed and will not reach the earth for hundreds of thousands of years.
If you do a google on it there is tons of information on it.

Thanks everyone.

But when it says the following

Quote:
No one knows exactly when the bulk of the supernova debris will hit the ring. Most prediction say 2003 - 2010 or so.
The ring does that mean the ring of the supernova. Why would it take that long since 1987 to hit the outer layer of itself

You need to go back and read the previous few weeks of stuff too. There's more than just one page on it. A quick summary is the rings formed during the expansion/shrinkage of the star prior to the actual explosion as faster solar winds collided with slower winds and piled up gas into the rings.

The rings are not the outer layer of the star, they're formed from the gasses that got blown off by the solar winds.

Well, they are about 1-2 ly from 1987A, and and 1987A is about 170,000 LY from Earth. So the rings are about 168,000 LY away.

wow so if it takes about 10 years to travel the 1-2 ly how long does it take for the 168 000

Approximately 840,000 years.

Ok, I know I'm going to have a #-o moment, but I just don't see what you're talking about.

I told you I was going to have a #-o moment. Oh, well, thanks Grey and Nergal. Besides, I did say about. ops:

To be fair, I think even the best estimates of the distance to the LMC have an error of 5% or so, and if you take into account that using different distance methods give a spread of results, it would be hard to more confident than 10%. So what's a couple thousand light years?

To paraphrase another users quote:

Approximately 840,000 years.
Which means that the year 842,005 CE will mark the end of the world as bmpbmp knows it!

Speaking of which, yo, bmpbmp! How about changing your URL so it reads like this:

Understanding of course, that in 850,000 (give or take a few thousand) years the world won't be as bmpbmp "knows it" irregardless of the supernova.

That is a LOOONG ways away. You'd probably be able to detect the particle stream with good instruments, but that stuff isn't being focused in our direction. As a practical matter, it would be completely irrelevent.

So, what would happen if debis from a supernova hit Earth? Would it be like a solar flare (satellites disabled, auroras, possible hazard to astronauts)? Or would it do anything at all?

Yeah, I know, but none of that will stop bmpbmp from worrying about it.
