@metal-brain saidThose heavy elements are actually thrown out of supernova explosions.
One word, "spin".
Some neutron stars seem too massive to not collapse into a black hole. The reason is the rate of spin. Remember, if neutron stars did not spin at an extremely fast rate there would not be enough centrifugal force for heavy rare metals to escape. That is the theory as to why gold and other rare metals are on our planet. If that theory is wrong those rare heavy metals do not come from neutron stars as has been claimed.
@suzianne saidWhat is your source of information?
Those heavy elements are actually thrown out of supernova explosions.
@metal-brain saidThat is todays Standard model. You could read Greenwood/Earneshaw The chemistry of The Elements (chemistry undergraduate textbook) chapter one. They do give Sources for further reading.

@ponderable saidSupernovas do not produce elements heavier than Iron according to what I have read.

I assume that any other textbook on inorganic chemistry would be a good start here.
@ponderable saidHe wouldn't be the slightest bit interested. He is never interested in learning something new. He just says "What is your source of information?" thousands of times like a stuck record player purely to bully and troll.

@metal-brain saidNO, that is NOT "according to what" you "have read".
Supernovas do not produce elements heavier than Iron according to what I have read.

@humy saidIt is according to what I have read. You don't know what I have read. Only I know that.
NO, that is NOT "according to what" you "have read".
That link does NOT say or imply anywhere that "Supernovas do not produce elements heavier than Iron" and in fact implies the exact opposite.
Having problems with reading comprehension?

I truly don't understand how you read so much but understand so little of it.

I answered the question from the creator of this thread. You are welcome.
When did I ever claim neutron stars produce ALL of the heavy metals in the universe?That isn't what I claimed you claimed.
This is all theory we are talking about. There is no certainty of the current scientific consensus.False. There is a current scientific consensus on this. To find it you have just to read it. Actually your own links more than hint on what that scientific consensus is.
I am not even fully convinced neutron stars produced any of it on earth.
@metal-brain saidThis isn't quite right, but not entirely wrong either. During supernova explosions a lot of neutrons are emitted by the progenitor star's core and the ejected material from the outer layers absorbs the neutrons, which provides the mechanism for the production of elements heavier than nickel. However, most of the platinum in the world comes from neutron star collisions (I believe, this is from memory and the theories on this are in a constant state of flux).

@deepthought saidI'm not sure what you are trying to say. I didn't say spin alone caused ejection. The collision would have to be a factor in my opinion. I was thinking the combination of the two, but it is still a lot of gravity to overcome. I would think someone would have measured the spin of bigger neutron stars and calculated the centrifugal force to see how the theory holds up.
