how does a blackhole works

does it suck all planets or something, can i jump on a blackhole and survive, would i be any taller

Very very tall

Black holes are fascinating and mysterious objects in the universe. They form when massive stars undergo a supernova explosion at the end of their life cycle. The core of the star collapses under the force of gravity, and if the core's mass is above a certain critical value (approximately three times the mass of the Sun), it will continue to collapse, eventually forming a black hole. Here's a basic overview of how black holes work:

Gravitational Collapse: As the core of a massive star collapses, its gravity becomes incredibly strong. This intense gravitational pull causes the matter in the core to be compressed into a very small volume.

Event Horizon: The core's collapse creates a region around it called the event horizon. The event horizon is the boundary beyond which nothing can escape the gravitational pull of the black hole, not even light. It is the point of no return.

Singularity: Inside the event horizon lies the singularity, which is a point of infinite density and gravitational force. The laws of physics, as currently understood, break down at the singularity, and our understanding of what happens there is limited.

Black Hole Properties:

Mass: Black holes can have varying masses, from a few times that of the Sun to billions of times the mass of the Sun.
Size: The size of a black hole is determined by its mass and is typically very small, with a diameter proportional to the mass.
Spin: Black holes can also have angular momentum, causing them to spin.
No Escape: Anything that crosses the event horizon is trapped inside the black hole, and there is no way for information or matter to escape from it. This is why black holes are "black" - they do not emit any visible light.

Effects on Space and Time: Black holes warp space and time around them dramatically, causing extreme gravitational effects. This phenomenon is described by Einstein's theory of general relativity.

Hawking Radiation: Despite their name, black holes can emit a form of radiation called Hawking radiation, which is a result of quantum mechanical effects near the event horizon. Over very long periods, this radiation can lead to the slow evaporation of black holes.

Black holes are still the subject of active research and ongoing scientific exploration. They continue to challenge our understanding of the fundamental laws of physics, particularly at the intersection of general relativity and quantum mechanics. Studying black holes can provide insights into the nature of gravity, spacetime, and the universe itself.

I think even light cant escape from a black hole, unlucky

if you jump in there you will sufer from a fenomenum called Spaghettified.
for example, an object is stretched in the direction of the black hole (and compressed perpendicular to it as it falls).
