Harry, A single blackhole, even of the supermassive variety, cannot produce all the expelled clouds! Only supernovae, with help of strong wind from young, hot, massive stars, can do it. Any jets emanating from a blackhole would be very narrow rather than spreaded out. Please read the explanations th...

ta152h0 I mentioned the next part of Pogge's lecture in my last post. It explains how the rest of the periodic table is created during a supernova. I will give the link here. http://www-astronomy.mps.ohio-state.edu/~pogge/Ast162/Unit3/supernova.html Dave H I am not sure if a merger of two neutron st...

Harry, For a high-mass star (more than 8 solar masses), it will be after helium fusion...LONG after helium fusion. Before the star will explode (as a Type II supernova), the star's core will have to go through not only helium burning, but also in sequence, carbon-oxygen burning, neon burning, anothe...

Harry, It seems to me that you and the authors in that link have a fundamental misunderstanding of what a neutron star is. I would be surprised if those authors' paper was accepted for publication as they simply didn't know what they were talking about! They are chemists, not astrophysicists! What i...

:roll: jfgecik, what are your REAL reasons for not believing that global warming is actually happening due to human activities? Are you afraid that if it is true, you would be forced to cut back your wasteful lifestyle of driving gas guzzlers, living in a big house burning incandescent lamps and set...

:roll: Hi, guys! I just read through this topic, and I can only shake my head at some of the posts here. A lot of misunderstandings and ignorance shown here could have been avoided if some of you took the trouble to use Google or some other search engine to research a lot of space facts. There are a...
