Canis Majoris will eventually be a back hole all on its own.

Not enough info. If black hole is small and in a far-off orbit it will turn into Hawking radiation before devouring the sun.

>>1532955
A star that big will not become a neutron star, it will go nova and the remaining core will become a black hole.

>> No.1532982

>>1532968
Or... a neutron star! Which in turn can be a pulsar or a magnetar, or just a neutron star.

Except it might be so massive photon pressure sheds the outer layers and it drops below the TOV limit before electron degeneracy is overcome.

What would you guys rather see, VY torn apart by a black hole, or r136a1?

With at least 260M☉ compared to a measly 30, it should make for interesting viewing.

No way that could happen with a star this big. No Fucking way. Theres way way way too much mass. Even if it lost nearly a hundred percent of its mass it would still become a black hole.

>>1533084
It's the other way around, the more mass the star has the bigger it's radius is, the more mass it sheds early in stellar evolution. And it's the mass in the later stages that determine the ultimate fate of the star.

How the fuck would Canis win? If the two collided, the black hole would just grub out the star.

I have a question that's always wanted to know.
Super massive stars that are at the end of their life cycle can undergo Nova/Supernovas to become either Black Holes or Neutron Stars depending on how massive the former star was.

The left over matter in a neutron star pulls back together and as it constricts it begins to spins extremely rapidly creating magnetic fields that pulsate giving off energy.


Over time this energy is transferred out into space causing the neutron star's revolutions to slow down. What eventually happens to the neutron star? They are called "inert self-gravitators" but do they really exist in perpetuity? Even black-holes are believed to evaporate due to hawking radiation after some time.

Also could it ever occur that all black holes in the universe eat each other creating just a single super black hole that attracts everything in totality?

>> No.1533168

>>1533114
I never said it was. But if you're a star volume is a function of mass (among other things).

>> No.1533208

>>1533163
Neutron stars are possibly the longest lived things in the universe, ultimately only decaying through neutron tunneling.

I'm not sure what your question is. Will the neutron star eventually stop spinning? Yes. Will it cool down? Yes.

If the density parameter of the universe was high enough then yes, a black hole could have eventually swallowed everything. Though it would be hard-pressed to finish the job before the universe ended in the Big Crunch, although I'm not sure that there's truly a distinction.

However, in reality, the density parameter is too low, so this will never happen: the universe is simply expanding too quickly for even the biggest black hole to overtake the expansion. Add on top of that the fact that the universe is accelerating, and it becomes apparent that black holes won't even be a majority population.
