Neutron Stars Collide, Create Black Hole, Release Gamma Ray Burst

10/16/2017 4:36 PM

brutal collision of two objects million solar mass each

WOW! Big things in happen in big space.

When it does, it can cause disruptive things to happen on Earth. I think Earth has not had a direct hit from a gamma ray burst in a long, long time. I hope it will be a very long time before the next direct hit.

Kilonova sounds like a hard core rapper or a heavy metal band.

It is more like there is a band or series of bands of heavy metal gas being slung off into space around such events, due to the high flux of hot neutrons bombarding the ordinary matter hanging around.

Maybe the chirps from such events could be strung together into some form of music.

The music has been published (with a nice graphic) on http://www.bbc.co.uk/news/science-environment-41650745

I don't think Steve king will give it to you, but you can ask.

To quote from your link:

["That debris is strange stuff. It's gold and platinum, but it's mixed in with what you'd call just regular radioactive waste, and there's this big radioactive waste cloud that just starts mushrooming out from the merger site," Kasen says. "It starts out small, about the size of a small city, but it's moving so fast — a few tenths of the speed of light — that after a day it's a cloud the size of the solar system."

According to his estimates, this neutron star collision produced around 200 Earth masses of pure gold, and maybe 500 Earth masses of platinum. "It's a ridiculously huge amount on human scales," Kasen says. He personally has a platinum wedding ring and notes that "it's crazy to think that these things that seem very far out and kind of exotic actually impact the world and us in kind of intimate ways."]

We can split the metals this way: I will take the silver, the platinum, the mercury, the rhodium, the palladium, the iridium, and the copper (if any), and all the other heavy ones, including the uranium (which I suspect is well worth its weight in gold).

The tungsten alone would be a fortune.

Both of us would be totally crushed under our fortunes. These are extremely massive stars to begin with, and thus large crucibles for making the heavy star dust.

On a sadder note, none of us need go around with our tongues sticking out expecting gold flakes to land on them, either.

It seems I win, if I just took the platinum, and you the gold! But with that much it would be ridiculous.

It's yours: go and get it.

Slightly more realistic: go and lay claim to a cubic mile of seawater. There's 38 pounds of gold in that.

Just think (as have many chemists), if you could perfect an ion exchange or filter mechanism to collect all 38 lbs/cubic mile. I think the pump energy still about kills the deal.

I would imagine most of the heavy elements get sucked into the black hole that develops. which makes me realize that at some time far far into the future, in the cosmos, there will be nothing left but black holes. and then they would cannibalize. would there be a time when there is just one? and does it then all start over?

Nah, that is truly the end (of this universe), but if space-time continues expansion, I would really not expect even the most massive black hole of all to have an event horizon that included the totality of space-time, so there never will be just the one.

Maybe other 'branes are sucking energy out the back end of the black hole discontinuity? Our maths do not go that high.

Okay - so when is it going to get here and fry us all?

already went by - didn't you get the duck and cover memo?

I don't think we got a direct hit, just that our astute astronomers picked up the G-waves on LIGO, then did a fast sky search, and found a bright binary neutron star pair going through the final throes of merging. Pretty awesome space snooping, actually.

I'm wondering if there are any super-heavy elements formed from the hypothesized "island of stability".

Naturally, reporters would glom onto gold and platinum, and leave out the rest. I fully expect if Glen Seaborg were still around, he would give us an affirmative nod.
