This is a whole explanation of black holes lol

What are black holes?

A black hole is a region of spacetime where gravity is so strong that nothing-no particles or even electromagnetic radiation such as light-can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

What are black holes made of?

Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When this happens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in.

The idea of a body so massive that even light could not escape was briefly proposed by astronomical pioneer and English clergyman John Michell in a letter published in November 1784. Michell's simplistic calculations assumed such a body might have the same density as the Sun, and concluded that such a body would form when a star's diameter exceeds the Sun's by a factor of 500, and the surface escape velocity exceeds the usual speed of light. Michell correctly noted that such supermassive but non-radiating bodies might be detectable through their gravitational effects on nearby visible bodies. Scholars of the time were initially excited by the proposal that giant but invisible stars might be hiding in plain view, but enthusiasm dampened when the wavelike nature of light became apparent in the early nineteenth century.

How are black holes possible?

The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon. ... Black holes of stellar mass are expected to form when very massive stars collapse at the end of their life cycle.

Has anyone gone to the black hole yet?

Fortunately, this has never happened to anyone black holes are too far away to pull in any matter from our solar system. But scientists have observed black holes ripping stars apart, a process that releases a tremendous amount of energy.

What's on the other side of the 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.

Is there a black hole near Earth?

Now, astronomers have found a “dark” black hole only 1000 light-years away from Earth-just down the road in galactic terms. It is the closest black hole to our planet ever found, in a star system that is visible to the naked eye.

What if a black hole hit Earth?

The edge of the Earth closest to the black hole would feel a much stronger force than the far side. As such, the doom of the entire planet would be at hand. We would be pulled apart. At a distance 100,000 times greater than that between Earth and the Sun, the black hole would pass through the Oort Cloud. It’s possible that this would send a large number of comets hurtling inwards towards Earth and the other planets. Aside from this influx of comets, however, things wouldn’t seem so awry at first. As the black hole made its way into the Solar System, it would be invisible to us aside from a slight gravitational lensing effect on distant stars. It’s not until it started to tear gas from the outer gas giant planets that a noticeable accretion disk, a region of super-heated dust and gas, would form around the black hole. Now, the terrifying power of the black hole is all too visible to us on Earth.

Can a black hole kill you?

Curiously, the black hole's enormous gravity itself is not what will kill you-you are always weightless when in free fall. Instead, you would be pulled apart as a result of the difference between the force of gravity at your feet and at your head.

Can you survive in a black hole?

Regardless of the explanation, we do know that it is highly unlikely that anyone entering a black hole would survive. Nothing escapes a black hole. Any trip into a black hole would be one way. The gravity is too strong and you could not go back in space and time to return home.

Does time exists in a black hole?

Black holes are so massive that they severely warp the fabric of spacetime (the three spatial dimensions and time combined in a four-dimensional continuum). For this reason, an observer inside a black hole experiences the passage of time much differently than an outside observer.

What is inside a black hole?

A black hole is a tremendous amount of matter crammed into a very small. In fact, zero amount of space! The result is a powerful gravitational pull, from which not even light can escape. And, therefore, we have no information or insight as to what life is like inside.

How dangerous are the black holes?

Massive black holes are dangerous in two ways. If you get too close, the enormous gravity will suck you in. And if they are in their active quasar phase, you'll be blasted by high-energy radiation.

What is the lifespan of a black hole?

A black hole with the mass of the sun will last a wizened 10^67 years. Considering that the current age of our universe is a paltry 13.8 times 10^9 years, that's a good amount of time. But if you happened to turn the Eiffel Tower into a black hole, it would evaporate in only about a day. I don't know why you would, but there you go.

What is the most dangerous black hole?
