What is black hole? Is there some place in Ocean resembles to black hole?

Answer 1

A black hole is an immensely massive (dense, heavy) and immensely small (tiny) object in space that has such a strong electromagnetic and gravitational pull, it sucks light photons into it, making it look like there is a giant hole in the universe.

Nothing anywhere on this planet, including in the ocean, is anything like a black hole.

Answer 2

Black holes are theorized to exist in the cores of galaxies, due to the massive companion star that feeds if. Black holes are so massive that their escape velocity exceeds the speed of light, therefore not even light can escape from them. The ocean is not in outer space and so it cannot even begin to resemble a black hole.

Answer 3

A black hole is a concentration of mass great enough that the force of gravity prevents anything past its event horizon from escaping it except through quantum tunnelling behaviour (known as Hawking Radiation). The gravitational field is so strong that the escape velocity past its event horizon exceeds the speed of light. This implies that nothing, not even light, inside the event horizon can escape its gravity. It is, however, theorized that wormholes can provide an exit path for energy or matter. The term "black hole" is widespread, even though it does not refer to a hole in the usual sense, but rather a region of space from which nothing can return.

The existence of black holes in the universe is well supported by astronomical observation, particularly from studying X-ray emission from X-ray binaries and active galactic nuclei

Answer 4

The simple definition of a black hole is an object that is so massive that the excape velocity (velocity that an object needs to be traveling in order to excape the gravity of the object...take a rock and throw it up...it goes up and comes down...throw it harder the rock moves faster, goes higher, then returns...the excape velocity is how hard (fast) you must throw you rock for it not to come down.)...sorry but if you didn't understand excape velocity you won't understand what a black hole is.

According to Einstein nothing can go faster than light, so if the excape velocity is larger than light's velocity (about 3*10^8 m/s) nothing can excape from the black hole's gravity.

An interesting note is that as the black hole "swallows" up mass as it pulls stuff to it. The gravity gets larger and and you cannot fly by it at the speed of light closer than the "Event Horizon"

Answer 5

The deepest part of the ocean is sometimes referred to as "The Abyss" , and I believe The black hole is a referance to outer space, infinity or outer darkness, whichever you prefer..
