30 Interesting Facts About Black Holes

Interesting Facts About Black Holes

The only things in the universe that can actually stop light from moving is a black hole. Scientists believe they are the result of the dead star’s core collapsing in on itself and thickening to the point where it warps space and time. Any matter that accomplishes this spirals haplessly toward their event horizons, also known as the no return point. These enormous cosmological occurrences are still a mystery despite decades of study. Scientists that study them are still in fascinated of them. Here are 10 Interesting Facts About Black Holes:

Interesting Facts About Black Holes

The gravitational force of a black hole is very large

that it is able to distort the space around it.

Nothing can leave a black hole.

It even attracts photons of light to yourself.

It is quite possible to see it visually.

It looks like a black sphere surrounded by a bright halo – an accretion disk.

They may well have their own planetary systems.

black holes things to know

The emergence of life on a planet revolving around a black hole is considered impossible.

Its monstrous gravity will attract all comets and meteorites to you, and nothing will fall on the surface of the planet from the outside, no organic matter, so it will remain sterile.

Black holes are not eternal.

They lose mass due to Hawking radiation and gradually evaporate.

If two black holes meet, they will merge, giving rise to exotics.

a kind of spinning black hole. Usually they don’t revolve around your axis.

In the centers of many galaxies (but not all!)

there is a supermassive black hole. Our own Milky Way also has one.

The density of these celestial bodies is unimaginable.

For comparison, if our Earth suddenly became a black hole, its diameter would be about 18 mm.

In 2019, scientists were able to photograph for the first time a supermassive black hole

located in the center of the Messier 87 galaxy and 54 million light-years away from us.

They can be formed in two ways –

in the case of a collapse of a rather massive star or the central part of the galaxy (or simply protogalactic gas, from which galaxies are formed).

In theory, black holes can serve as an inexhaustible source of energy.

There are reactor projects that would create and maintain a microscopic black hole, but are still far from being implemented in practice.

The boundary beyond which there is no exit

from the gravitational field of a black hole is called the event horizon.

An object that has crossed the event horizon,

for an external observer, will extend in a thin, long line. This effect is called spaghetti.

If black holes exist in the universe, according to astrophysicists,

then there must be whites, which are their complete antipodes. They don’t attract matter, but repel it. It is true that the existence of white holes has not yet been proven.

The supermassive hole at the center of the Milky Way is about 26,000 light-years away from us.

black holes facts

In the qv telescope’s triple star system,

one of the three stars is probably a black hole.

If the sun turned into a black hole,

its diameter would be about 6 km. But that doesn’t threaten him.

Currently, scientists have already discovered about 1000 objects,

which, according to a number of characteristics, belong specifically to black holes.

A dying black hole in the final stages of evaporation passes through a powerful gravitational explosion,

from which gravity “waves” propagate in all directions.

The fastest rotating black hole we know makes about 1000 revolutions around its axis per second.

The mass of the supermassive hole at the center of the Milky Way is,

according to scientists, 2 to 5 million solar masses.

In the constellation Canis Hounds there is a quasar,

that is, the “embryo” of the galactic nucleus, and in it there is a supermassive hole with a mass of about 66 billion solar.

The galaxy NGC 1277 is interesting

because its supermassive central hole represents about 59% of the total mass.

Matter, crossing the event horizon, generates waves as sound,

so that the “sounds” produced by the black hole can be heard. This was first done in 2003.

Between the Sun and mercury’s orbit, it would be quite possible to place a black hole

with a mass of up to 4 million solar masses, that is, comparable to that located in the center of our Galaxy.

Passing the event horizon, matter accelerates to the speed of light.

These objects pose no danger to space travel unless you get too close to them.

galaxy facts

To have the chance to change into a black hole in the final stage of its evolution,

the star must be at least ten times more massive than the Sun.

The monstrous gravity of black holes forms gravitational lenses in space,

thanks to which astrophysicists can detect them.
