The Crab Nebula
We all read that there was a day the sun stood still. It might have been
days that there was no "dark" night sky. It had to be the biggest explosion ever witness by mankind. Still talked about after 1054 as recorded by Chinese astronomers. The Crab Nebula is still expanding(over coming gravity) at our present time. I wonder how many H-bombs explosions it would take to equal that supernova explosion? How much dark matter that was created and blown through space? Did it leave at its core a blackhole or a neutron star from the implosion? Astronomers only talk about the 100 odd chemical elements created by the supernova explosion being in the form of dust particles. Could some be bigger than dust and be as big as a small rock planet,say the size of our moon? Some how I see comets can give answers to some of my thoughts. When those aerogel panels come back to Earth with captured comet dust (comet Wild-2) it might have the right stuff to give us the right answers. Bert |

It was about four times brighter than Venus - still no where near as bright as the full moon, so forget the no dark night sky stuff. http://www.seds.org/messier/m/m001.html I wonder how many H-bombs explosions it would take to equal that supernova explosion?

A pulsar (rapidly rotating neutron star) appears to be the remnant. No dark matter apart from neutrinos would have been produced.

Well 4 times brighter than Venus plus the light of the moon might have
caused night stark shadows. People do go over board in their thinking over long time lapses. Still the light of that supernova explosion was seen during the day. How can we be sure how bright it was without being there?. It had to be a bit scarry in those ancient times. Bert |

Bert As far as I know, the brightness estimate is based on the reports of the Chinese observers. Venus is actually visble during the day when well separated from the sun. http://www.fourmilab.ch/images/venus_daytime/ To see it, you have to completely block the Sun from the view. WARNING - if you attempt this, be extremely careful. Especially if you are using any optical aid to initially locate the position of Venus. Rgds Llanzlan. |

Hi Rgds I find that interesting that Venus can be seen in day light,if
you know where to look. I think I read(long time ago) that this supernova explosion's light lasted for two weeks. Was that the length of the explosion? I would think being an explosion the light would only last a second,especially since the supernova is surrounded by just the vacuum of space. Could these great explosions disrupt the fabric of space? I'm working on a theory that space creates inertia,and it could fit in here nicely. Its on the lines of Mach thinking Bert |
