What are Blackholes?

Science report

Today’s topic is: What are Blackholes?

Introduction

There is something in the universe where you would not study physics, why…because physics does not apply to black holes.

Black holes

They are the remains of a dead star that collapsed under its own weight and possesses a great density and gravitational pull.

Do you know?: The black hole has such great gravitational pull that it doesn’t even let the light pass through it.

Mathematically speaking if you were to compress an object to a certain ratio of its original mass then you have formed a Blackhole! Like if you compress earth to a size of a peanut then you would have a Blackhole.

Event Horizon

There are some special parts of a black hole that have different properties and show a distinct effect on contact with the mass.

The event horizon is the outer part of the black hole where if you enter it then say goodbye to your relatives cause you are not returning from there.

Do you know: As the earth has an escape velocity of 11km/sec the black hole has an escape velocity of more than the speed of light. 

Singularity

Do you know noodles? Well, your knowledge of the shape of noodle will give you marks. After a hypothetical fall into the black hole, after you cross the Event horizon(its no turning back,) you reach Singularity where your total density becomes one with that of the black hole you will stretch and be torn apart from the forces, that process is called Spaghettification. 

Fun fact: Time in the Blackhole and the earth are different. If we took the time according to the speed of light then time at the event horizon would be late compared to the earth.

The nearest Black Hole

The nearest black hole to earth is 1,500 light-years from earth. The name is “The Unicorn”. Its mass is 1/3rd of that of the sun(one of its kind)

The Puzzle

We don’t know how will it be inside the black hole or how does time work inside a black hole. There are many such mind-blowing and boggling questions the humanity does not have answers to. 

If you have such questions you want an answer to. So comment down below and I may(100%) write a blog about it.

Bye! Have a great time
