• What is Black Holes?

A black hole is a region of spacetime displaying gravitational acceleration so strong that nothing no particles or even electromagnetic radiation such as light can escape from it. 

• Can time escape a black hole?

Nothing, not even light, can escape from inside the event horizon.Due to this effect, known as gravitational time dilation, an object falling into a black hole appears to slow as it approaches the event horizon, taking an infinite time to reach it.

• How does a black hole die?

According to  Hawking, the black holes would disappear. During drying, the black hole emits energy in the form of the positive particles that escape So, yes, black holes do die, and they do so when the theories of the extremely large come together with the theories of the very small.

• Could a black hole consume an entire galaxy?

The discovery is quite surprising since the black hole is five times more massive than the Milky Way's black hole despite the galaxy being less than five-thousandths the mass of the Milky Way. Some galaxies, however, lack any supermassive black holes in their centres.

• Will our black hole eat the Milky Way?

There is no way a black hole would eat an entire galaxy. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for eating the whole galaxy.

• Could a black hole delete the universe?

The black hole information paradox is a puzzle resulting from the combination of quantum mechanics and general relativity. Calculations suggest that physical information could permanently disappear in a black hole, allowing many physical states to devolve into the same state.

• 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 form is by stellar death.

• Do black holes teleport you?

Classically, a black hole may have one angular momentum, but in reality, its angular momentum can be described using quantum mechanics as a superposition of multiple possibilities. To do so, they relied on an algorithm that uses quantum teleportation in a black hole, or Hawking radiation.

• What is on the other side of a black hole?

The event horizon is a proposed boundary around a black hole. On the other side of it, the gravitational pull of the black hole is so strong that, in order to escape it, an object would have to be moving faster than the speed of light, a feat that almost all physicists agree is impossible.

• Can we create a black hole?

A black hole can have any mass equal to or above about 2.2×10⁻⁸ kg or 22 micrograms (the Planck mass). To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light.
