Star explodes halfway across universe

You know it was Carl Sagan who convinced the team in control of the Voyager at the time to take the picture. It always gives me chills when he discusses the event itself and how it shows just how insignificant this planet actually is in his book: Pale Blue Dot.



From the audiobook (with some music added in).

bye bye to life anywhere

I thought I heard millions of voices suddenly cry out in terror and then suddenly silenced.


Actually this story is crazy. It's weird to think this actually occurred before our solar system was even formed and now has finally reached us. The universe really needs to upgrade to a better news delivery system.

WoW - That means it happened 7.5 Billion Year ago! What's new today?:horse:

Yep..when this story was reported...that star went supernova 7.5B years ago.

You all should be happy to know there is finally a democracy in it's place now. Although we're not sure if the democracy would have happened eventually without the supernova.;)

thats really neat.
7.5 billion light years away.

so that does mean that it exploded 7.5 billion years ago right?
and does light have a life span? will it travel forever without extinguishing?

little help?

No half life for light Meest. And it bends around a solid body thus proving the theory of general relativity.

so that does mean that it exploded 7.5 billion years ago right? - Yes. :glugglug:
and does light have a life span? From what I know, light is energy. Energy will not get lost. If if would, the sky would be dark at niight. And the sky, is belived to be more than 7.5 billion years ago.

will it travel forever without extinguishing? Hmmh. - Yes! According to science the speed is constant. So one light year distance every year we count history. But then, some scientist even stopped light.

little help?
I hope this helps.

There are many unanswered questions. But then there are great crutches in science, to explain things of long long ago. Most need constant revisions, but they keep us going.
 
It's a Tad too far to effect us Luie. About 7.49998B pointed right at us and we'd be fucked.
You would not even have been born and had no idea.

There is no sun close by to explode like that, is there? And then when we see, we're dead shortly thereafter. Nothing to worry about, is there?:cool:

Light wave propagation is also subject to absorption (attenuation) just like other forms of electromag. radiation. Depending on the matter, light waves can be either absorbed (atoms taken up by the matter), reflected (bounced back), refracted (as when it passes through water) or deflected (redirected or scattered).

Thanks BB, that is a massive dose of perspective. :cool:

All true, inside an atmosphere, not in the vacuum of space which is what mr's question was about. You can't help it, can you.
