Understanding Black Holes: A Brief Overview
An educational summary for high school students
What is a Black Hole?
A black hole is a region in space where the gravitational pull is so strong that nothing, not
even light, can escape from it. Black holes form when massive stars collapse at the end of
their life cycle.
Types of Black Holes
There are three main types of black holes:
1. Stellar black holes – formed by the gravitational collapse of a massive star.
2. Supermassive black holes – found at the centers of galaxies, including the Milky Way.
3. Intermediate and miniature black holes – hypothetical types that are smaller or between
stellar and supermassive sizes.
Event Horizon and Singularity
The event horizon is the boundary around a black hole beyond which nothing can return.
The singularity is the core of the black hole, where gravity is thought to be infinite and
space-time curves infinitely.
Why Are Black Holes Important?
Black holes help scientists understand the fundamental laws of physics, including gravity
and quantum mechanics. They also influence galaxy formation and serve as laboratories for
extreme physics.
Did You Know?
The first image of a black hole was captured in 2019 by the Event Horizon Telescope,
showing the shadow of a supermassive black hole in the center of the galaxy M87.
