Black Hole

Our topic is all about Black Hole. What is a black hole? A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

Is there life in a Black Holes?

The 'Gravitational Singularity'

Black holes are essentially regions of space whose gravitational pull is so strong that nothing -- not even light -- can escape. It's for that reason that the phenomena are called "black," since all light hitting them gets absorbed, leaving nothing for the viewer to see.

Black holes can be either rotating or non-rotating, according to current theory, but either way, a "gravitational singularity" lies at the center.

Surrounding each black hole, meanwhile, is an invisible boundary known as the"event horizon" that essentially marks the point of no return. Anything that reaches a black hole's event horizon is expected to get sucked toward its singularity, with no hope of escaping again.

Death by 'Spaghettification'

Spaghettification (or death by black hole) is the process of what happens to matter when it falls into a black hole. Even though we cannot visually prove this due to the mass of a black hole is so high, causing the gravitational force of the black hole to be so immense that the escape velocity of the black hole is faster than the speed of light (just shy of 3×108 ms-1), we are still able to theorize what will happen with the support of equations (which will not be included don’t worry).

'Advanced Civilizations May Live Safely Inside'

So argues Dokuchaev, who suggests that there are stable, periodic planetary orbits inside black holes that neither begin nor end in the black hole's gravitational singularity. Rather, they orbit around and around somewhere between the event horizon and the singularity without ever approaching the singularity or its life-threatening "spaghettifier."

Such stable periodic orbits exist inside black holes for photons, and they may exist for planets as well, Dokuchaev writ

'Nothing We'd Recognize'

It's almost impossible to guess what it would really be like inside a black hole, Czysz asserted.

"Even [Stephen] Hawking retracted his statement as to what the conditions would be like," he explained. "All we know is that as you approach the edge of the black hole where the boundary is, the gravity is so high that even light can't escape."

Temperatures and pressure would probably also be extremely high, he pointed out.

"I don't know if anything could survive," Czysz added. "If it can, it would look like nothing we'd recognize here on Earth."
