What is true about black holes?

A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes.... view details ›

Why are black holes called black holes quizlet?

A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space. This compression can take place at the end of a star's life. Some black holes are a result of dying stars.... see details ›

A black hole has an infinite density; since its volume is zero, it is compressed to the very limit. So it also has infinite gravity, and sucks anything which is near it!... continue reading ›

What are the 4 types of black holes?

There are four types of black holes: stellar, intermediate, supermassive, and miniature. The most commonly known way a black hole forms is by stellar death. As stars reach the ends of their lives, most will inflate, lose mass, and then cool to form white dwarfs.... continue reading ›

Black holes are dense objects with gravity so strong not even light can escape them. The newly discovered black hole has a mass at least nine times greater than our sun. It was discovered in the Tarantula Nebula, a huge gas cloud in the Large Magellanic Cloud galaxy. It is about 160,000 light years from Earth.... view details ›

What is a black hole made of?

Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.)... see details ›

Astronomers have discovered the fastest-growing black hole known to exist in the universe. In its seemingly endless hunger, the supermassive black hole consumes the mass equivalent of our sun every two days. A black hole is an object with such overwhelmingly powerful gravity that not even particles of light can escape.... continue reading ›

Answer: Black holes don't really “explode”, which implies that they generate a large outburst of energy which ultimately tears them apart, but they do have outbursts (also, unfortunately, referred to as “explosions”).... see details ›

How does a black hole form from a massive star quizlet?

How does a black hole form from a massive star? During a supernova, if a star is massive enough for its gravity to overcome neutron degeneracy of the core, the core will be compressed until it becomes a black hole.... read more ›

At what point does an object become a black hole?

Any object that is smaller than its Schwarzschild radius is a black hole – in other words, anything with an escape velocity greater than the speed of light is a black hole. For something the mass of our sun would need to be squeezed into a volume with a radius of about 3 km.... see more ›

What would happen if the Sun suddenly became a black hole without changing its mass quizlet?

What happens to time near a black hole quizlet?

What are two of the three major parts of a black hole?

Black holes have three "layers": the outer and inner event horizon, and the singularity. The event horizon of a black hole is the boundary around the mouth of the black hole, past which light cannot escape. Once a particle crosses the event horizon, it cannot leave. Gravity is constant across the event horizon.... view details ›

Is there a black hole in the middle of the Milky Way?

In 2019, the Event Horizon Telescope team released the first image of a black hole — this one at the center of the galaxy M87. The black hole at the center of this galaxy, named M87*, is a behemoth 2,000 times larger than Sagittarius A* and 7 billion times the mass of the sun.... see more ›

While the mass and the spin of black holes are frequently considered in the majority of publications, the charge is often neglected and implicitly set identically to zero. However, both classical and relativistic processes can lead to a small non-zero charge of black holes.... see more ›

Can a black hole become full?

No, in fact they are a result of something being filled too much. Black holes form when a colossal amount of material gets crammed into a tiny space that's much too small for it all to exist at once. When this happens, it collapses into something called a singularity.... continue reading ›

Perhaps the most enigmatic objects in the Universe, black holes embody many unsolved paradoxes.... read more ›

Which of the following best describes a black hole?

Which of the following best describes a black hole? A place from which the escape velocity exceeds the speed of light.... see more ›

Yes. All astronomical objects, including black holes, are formed by gravity pulling matter together. If a cosmic body originates from anything that had even the tiniest amount of rotational motion originally, then this spin rate will become greatly enhanced as the object collapses.... view details ›

Are black holes solid?

When astronomers speak about them, they often make an unintentional impression that they are some kind solid objects. They are not. A black hole is a spacetime singularity that is enclosed by an event horizon. Both things are quite weird, but none of them is anything solid.... read more ›

Which of the following is not true about differences between novae and supernovae?

Which of the following is not true about differences between novae and supernovae? Supernovae eject gas into space but novae do not. Will our Sun ever undergo a white dwarf supernova explosion?... see more ›

Solution(By Examveda Team)

Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. A black hole can be formed by the death of a massive star. They are regions of space where gravity is so powerful that even light can't escape.... continue reading ›
