What Is a Black Hole?
A black hole is a region in space where gravity is so strong, nothing—not even light—can escape it.
How Is It Formed?
Usually forms when a massive star dies in a supernova explosion. If the remaining core is heavy enough, it collapses into a black hole.
Parts of a Black Hole:
Event Horizon – the point of no return. Once you cross this, you’re gone.
Singularity – the center. Infinite gravity. Physics breaks here.
Accretion Disk – a swirling disk of gas and dust falling in.
Types of Black Holes:
Stellar Black Hole – formed by collapsed stars (few times the mass of the sun).
Supermassive Black Hole – millions to billions of solar masses, found in galaxies' centers.
Intermediate Black Hole – in between.
Primordial Black Hole – hypothetical, formed in early universe (tiny but heavy).
What Happens If You Fall In?
You get spaghettified (stretched like pasta).
Time slows down (relativity).
No way out. Not even messages can escape.
Do Black Holes Suck Things In?
Nope, not like vacuums. You got to be close to feel the pull. Far away? You're safe.
How Do We Detect Them?
Gravitational waves (from collisions).
X-rays from matter falling in.
Star movement around “invisible” objects.
my note
i learned that black holes are invisible and not even light can escape
Where is your note?
How would space look like if black holes didn’t exist?
Could a black hole ever shrink or disappear? How?
What would happen if two black holes crashed into each other?
How can we “see” something in space that doesn’t give off light?
If a black hole doesn’t suck like a vacuum, why do people think it does?
Why can’t even light escape a black hole?
What makes a black hole different from just a really big star?
Do black holes grow bigger over time? If yes, how?
