Black hole

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed. In many ways a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.

Astronomers Spot Huge Black Hole

An illustrated view of a black hole that outgrew its galaxy- Almost all galaxies are thought to have a super-massive black hole at their cores that can make up for at most 0.5% of their cores. However, the discovery of a galaxy called CID-947 with a black hole that makes up 10% of its mass has left scientists questioning current theories on how galaxies evolve

A massive black hole sucking in a sun

This picture illustrates the awesome power that 1 black hole has. It is a force to be reckoned with and yet it is something that could be watched from a safe distance.

10 really simple facts about black holes that help us understand their place in our universe

Black holes are definitely something. A zone where space and time no longer exist, bending light and sucking up everything around it.

Black holes bend light and in this case this is a very extreme bending of light.

How would traveling inside a black hole (a space in the universe where gravity let's NOTHING, not even light escape) be like? Did you know we are ALL scientifically the CENTER OF THE UNIVERSE? Last, did you know humans are now creating a version of black holes but instead are "Dumbholes" where sound cannot escape instead of light? Watch this video and find out!!

What is Sussle?

Sussle is the first, open visual encyclopedia. Anyone can use it.

What's a visual encylopedia?

It has beautiful images and viral videos that are way more fun than reading all the text in traditional encyclopedias.

5 reasons you should add your own images and videos:

  1. If you found Sussle interesting, then give back by adding something interesting for others.
  2. Help others learn in a fun way.
  3. Make someone else interested in this topic laugh or say wow!
  4. Become internet-famous as people like and share your post.
  5. It's super easy, so it won't take more than a minute.
