Fun facts about black holes
14 Fun Facts About Black Holes: A 15-Minute Book by Jeannie MeekinsTV and movies will have you believing that black holes are huge holes in space and anything that falls into them is lost for all time – possibly falling into another universe or another time, or even falling forever.
You may think that black holes run around in space like huge vacuum cleaners sucking up everything in their path. This is not true.
But what actually is a black hole and what do they do? This book will help you find out.

What Are Black Holes?
Imagine matter packed so densely that nothing can escape. Not a moon, not a planet and not even light. But how did black holes come to be, and why are they important? Below we have 10 facts about black holes — just a few tidbits about these fascinating objects. Say a star happens to get too close to the black hole, for example. The black hole naturally pulls on the star and rips it to shreds.
Black holes are some of the strangest and most fascinating objects in outer space. They're extremely dense, with such strong gravitational attraction that even light cannot escape their grasp if it comes near enough. After decades of black holes being known only as theoretical objects, the first physical black hole ever discovered was spotted in The EHT saw the black hole in the center of galaxy M87 while the telescope was examining the event horizon, or the area past which nothing can escape from a black hole. The image maps the sudden loss of photons particles of light. It also opens up a whole new area of research in black holes, now that astronomers know what a black hole looks like. So far, astronomers have identified three types of black holes: stellar black holes, supermassive black holes and intermediate black holes.

A black hole is formed when a large star starts running out of fuel and begins to collapse under its own gravity. Such a star may become a white dwarf or a neutron star, but if the star is sufficiently massive then it may continue shrinking eventually to the size of a tiny atom, known as a gravitational singularity. The singularity at the core of a black hole may shrink to a size smaller than an atom, and eventually become an infinitely small point in space containing infinite mass. Here the gravitational force is so strong that the spacetime surrounding the singularity is bent to infinite curvature, and scientists are left searching for a good quantum theory of gravity to explain what is truly going on inside these incredibly dense objects. As time elapses, the light subsequently becomes red shifted and dimmer as its wavelength becomes longer, eventually disappearing from the sight of the observer as it becomes infrared radiation, then radio waves.
Black holes are among the strangest things in the universe. They are massive objects — collections of mass — with gravity so strong that nothing can escape, not even light. The most common types of black holes are the stellar-mass and supermassive black holes. Stellar-mass black holes are created when massive stars explode, leaving behind a black hole with the mass of just a few suns. Supermassive black holes exist in the hearts of galaxies and usually contain the mass equivalent of millions of suns.
The most intriguing, the most inspiring and the most elusive thing in the entire universe known to mankind is the Black Hole. There are hundreds of questions about Black Holes that are yet to be answered. Some of them have been answered while some others are still within theoretical frameworks and remaining keep giving birth to numerous science fictions we encounter on a day-to-day basis. So, what exactly are these Black Holes? What do we know about these entities? Black Holes are nothing but remnants of dead stars. Not all star s convert into Black Holes.
