NASA | Colliding Neutron Stars Create Black Hole and Gamma-ray Burst

Armed with state-of-the-art supercomputer models, scientists have shown that colliding neutron stars can produce the energetic jet required for a gamma-ray burst. Earlier simulations demonstrated that mergers could make black holes. Others had shown that the high-speed particle jets needed to make a gamma-ray burst would continue if placed in the swirling wreckage of a recent merger.

Now, the simulations reveal the middle step of the process--how the merging stars' magnetic field organizes itself into outwardly directed components capable of forming a jet. The Damiana supercomputer at Germany's Max Planck Institute for Gravitational Physics needed six weeks to reveal the details of a process that unfolds in just 35 thousandths of a second--less than the blink of an eye.

Oh my god that is amazing! The scales, densities, and energies involved are incomprehensibly large for me. Thanks for the briefing.

1:06 "Just a sugar cube sized piece of nautron star can weigh as much as all the water in the Great Lakes."

Hmm for the Great Lakes' total weight, my calculations show 20, 000 billion tons. A sugar cube is about a teaspoon; a tsp of the core of a neutron star is thought to weigh probably 10 billion tons (at a density of 1e15 g/cm^3). So this would be off by a factor of roughly 2, 000.

But what is a star?

What an amazing sight, wish I could see this 1st hand. What an awesome sight.

This was actually proven today. Good job👌

Neutron stars formed from supernova events are prohibited from becoming black holes because it is thought that the gravitational force is not enough to overcome Fermi degeneracy of the neutrons or quark gluon soup at the core of these objects, however, addition of more mass can overcome this repulsion and form a black hole. My question is are black hole "cores" not singularities but instead massive bosons formed by the gravitational effects forcing quarks into a singular microstate similar to the formation of Cooper pairs?

It's amazing how it happens soooo fast

[Anonymoose]

Incredibly fascinating, and in a way it makes my brain hurt. As the scope of the known Cosmos expands, it becomes more and more intimidating.

@bra13vo we were only teasing....hope you have a great weekend and take care

A small note - The matter on the surface of the neutron stars will start experiencing smaller gravitational fields. Is Lagrange Point One figured into the calculations? Because at some point the degenerate pressure will overcome the gravitational pull and the matter will start flying off of the surface the stars at a high rate of speed in a rotating doughnut shape, which will be concentrated at the poles of LG1. You now have more than​ enough matter to create jets of plasma.

Well
Whatever She just said about exploding stuff
Is going on in my head

[ARTVBASIC]

So true and very well said AzaDee... we pay too much attention to our little insignificant differences and fail to see the bigger picture.

wow gamma rays seem so amazing and beautiful! i want to warp through space where one is about to take place and look at it through a telescope *_*

[archonjubael]

Can I see the code for this simulation?

[keithwright]

I guess what I'm asking is the following; 1) Is gravitation strong enough to overcome quantum fluctuations of the material (fermions) present at a neutron star core as it proceeds with additional mass to the transition from a neutron star towards full gravitational collapse  and 2) would such material be compacted to the extent that there are no "degrees of freedom" essentially forcing fermions to exhibit bosonic character with a microstate of one at zero degrees Kelvin at the "core" thus avoiding singularity while preserving quantum number as well as mass - energy conservation? Present knowledge would suggest the short answer of no, I just want to know why. Respectfully, Keith Wright.

That's a Kamehameha

@julsHz yah it seems like it would be really complicated. I tried a non-graphical simulation of a ball bouncing (including the complete flex of the ball when it touches the ground), and that took months. The code on this would be insane.

[DjSharperimage]

WOW!!!
This is how BlackHoles are created;
Amazing
