In the center of our galaxy, there is a supermassive black hole that is devouring the stars around it. This is Sagittarius a.
If it’s not terrible enough that a giant monster with strong gravity is slowly eating away at the whole galaxy, is there another terrible monster in the universe lurking around it? Will they collide with each other? How will their impact destroy the galaxy? What impact will this have on the earth?
What happens if a magnetostar collides with a black hole? This behemoth crawling through the Milky Way galaxy is a remnant of the explosion of a huge star.
But this is not an ordinary stellar remnant. It is the core of a collapsing star with extremely high density and magnetism.
Let’s refresh your understanding of magnetostar. Suppose there is a star whose mass is at least eight times more than that of the sun. When it comes to the decline period, after a magnificent supernova explosion, magnetostar is born.
After the explosion, the star lost most of its volume, but it also left behind a dense core. Most of these stellar remnants become neutron stars. Neutron stars rotate very fast, usually many times per second.
They are composed of neutrons. Some neutron stars have strong magnetic fields, which are strong enough to emit electromagnetic radiation from their own poles. This is pulsar. When the poles of the pulsars face the earth, you can see them with a telescope.
Only a few of these pulsars can form extremely strong magnetic fields. They will become the most powerful magnets in the universe.
Although they can complete their rotation every ten seconds, their magnetic field is hundreds of times stronger than that of an ordinary neutron star. If there is such a magnet between the earth and the moon, it would be a bad thing.
But if it was 26 light-years away, would it be just as bad?
Xiaobian is curious, can magnetic stars devour black holes? Or do black holes devour magnetostars?
The collision of these two giants will not cause an explosion. They will only merge quietly in the universe, which will last for billions of years. Although the magnetism is very strong, they may still be lost to black holes.
It depends on the trajectory of the magnetostar and the size and mass of both magnetostar and black hole. Magnetostar may be swallowed by the black hole as a whole, or slowly and gradually.
When a magnetostar is torn apart by a black hole, it will release gravitational waves to the whole universe, disturbing the curvature of space-time. Once the black hole completely engulfs the magnetostar, its mass will increase and its surface will expand.
As the surface of the black hole expands, more and more stars will be sucked into the abyss of the black hole. The black hole will slowly swallow the stars in the galaxy one by one.
Eventually, after eating stars for billions of years, the black hole will swallow up the entire galaxy. At that time, it is very likely that human beings would have disappeared long ago. Unless there is another celestial activity in the universe, it will disturb the black hole, a meal that took 4.5 billion years.
Xiaobian thinks that the universe is really profound. All kinds of strong people exist in the universe. Maybe there are more powerful roles than black holes and magnetic stars.
