What happens when a pulsar encounters a black hole?

When pulsars encounter a black hole, they will quickly spin around each other and approach each other in the winding. Eventually, the two celestial bodies were torn apart by each other's strong gravitational pull and merged back into a black hole.

Pulsar. It is a neutron star that rotates at high speed, because it constantly emits electromagnetic pulses.

signal. Pulsars are known for their small scale, strong gravitational pull, strong magnetic field, and strong electromagnetic radiation.

And famous. At the end of the evolution of the star, it lacks the raw materials for nuclear reaction to continue burning, and the internal radiation pressure decreases, and it gradually collapses due to its own gravitational effect. Stars with insufficient mass (about several times the mass of the Sun) collapse and rely on electron degeneracy pressure to compete with gravity and become white dwarfs.

In a star with a mass greater than that, electrons are pressed into the nucleus.

Neutrons are formed, when the star relies on the degenerate pressure of neutrons to maintain balance with gravity, which is a neutron star.

A typical neutron star has a radius of only a few kilometers to a dozen kilometers, but its mass is between 1-2 times the mass of the Sun, so its density can reach hundreds of millions of tons per cubic centimeter. As the angular momentum is conserved when the star collapses.

After collapsing into a neutron star with a small radius, the rotation speed tends to be very fast. And because the magnetic axis of the stellar magnetic field is usually not parallel to the axis of rotation, some even reach an angle of 90 degrees, and electromagnetic waves.

It can only be emitted from the position of the magnetic poles, forming a conical radiation region. When its cone-shaped radiation periodically sweeps over the Earth, it behaves as a pulsar.

Pulsars will periodically emit pulse signals, if the earth passes by its side, it will not directly suck the earth into it like a black hole, but will attract the earth and destroy the earth's life with powerful electromagnetic waves at the same time, the earth will almost be torn into pieces, the powerful pulse will also periodically give the earth a strong vibration, and the earth will be melted into the pulsar in endless torment.

As long as the Earth is kept at a safe distance from the black hole, the black hole has no effect on the Earth.

So, pulsars are more scary than black holes.

Pulsars are not scary. FAST has discovered many pulsars. Black holes can devour everything, which is more terrifying.

It is not the same, although both have strong gravitational pull, both are caused by the collapse of perseverance, but the essence is different.

A pulsar is a sphere with three-dimensional properties.

The so-called black hole is a point with only one-dimensional properties.

The black hole that everyone usually talks about is the "event horizon" that includes the black hole, which is the strongest gravitational range of this singularity, which you can understand as the signal range of WiFi, and there is nothing in this range. Because everything is absorbed by the singularity. So the true black hole density is positive infinity.

Pulsars are a type of neutron star, and the density of a neutron star is calculable and has an upper limit.

The so-called black hole center refers to those areas where external matter is not easy to enter, and there are few tangible materials, so there are blank areas in the center of the black hole. Since its attraction to the surrounding matter is almost uniform in every direction. Usually the trajectory of the matter around a black hole is circular and swirling.

Because black holes have different densities of matter distribution, there are usually no cantilevers around them, resulting in ray pulses with different radiation intensities in the same direction.

Pulsars and black holes are both products of massive stars when they reach their final level. But pulsars are not the same as black holes. They are not the same kind of celestial bodies.

Pulsars are fast-rotating neutron stars with strong magnetic fields, and the density is calculable and has an upper limit. Whereas, a black hole is a point with only one-dimensional properties.

Black holes are indeed terrifying, but compared with the horror of the unknown, the already terrifying is more suffocating.

It's like killing heads and Ling Chi.

And pulsars are Ling Chi who makes people feel suffocated.

A pulsar is a rapidly rotating neutron star second only to a black hole in density, which means that a black hole is likely to have developed from a pulsar.

Astronomers once discovered one of the brightest pulsars ever recorded, and they almost mistook it for a black hole. After measuring its output, astronomers were shocked that its output energy is equivalent to 10 million suns. That is, it has the energy to rival that of a black hole, but with a much less mass, which is incredible.

Pulsars will periodically emit pulse signals, and if the Earth passes by its side, it will not directly suck the Earth into it like a black hole, but will attract the Earth while almost tearing the Earth into pieces, and the powerful pulses will periodically give the Earth a strong vibration.
