5 More Interesting Facts About Space
#1
Travelling near a black hole makes you age slower relative to the people on earth.
As Einstein proposed, the universe is made up of spacetime and the more massive an object is, the more it warps spacetime. Gravity is how much an object warps spacetime. Black holes are known to have an infinitely large gravitational pull in its singularity.
If you were to travel close to a black hole, the warping of spacetime would be extreme and you would start to age slower and slower. If you were to dive head first into the black hole, for an observer, you would move slower and slower untill you completely stopped and eventually faded into darkness. Were you to come out of that black hole again you would return to earth realizing that the entire human civilization has died, except you.
#2
Space is completely silent.
In order for humans to hear sound, air has to be compressed in a certain pattern and wavelenght so be recepted by our ears and then turned into sound. Sound needs a medium to flow through, in our case it is air, but since there is no air in space it means that it is completely silent. Therefore, all action that takes place in Star Wars is actually completely silent.
#3
There is a bigger mountain than Mt. Everest and it is located on Mars!
While amazingly tall and sitting at 8,8 km tall, there is a mountain called Mt. Olympus located on mars that is taller. It is 27 kilometers tall and is estimated to be around 30 million years old.
#4
The we can only see stars from our own galaxy.
It is impossible for the human eye to see stars from another galaxy. Since there are millions of stars in The Milky Way, they block or outshine the light coming from intergalactical stars. We can't even see all the stars in our own galaxy.
#5
The moon was once a part of earth.
It is believed that the moon was a part of the earth during the early days of earths creation. After a while a comet hit earth and launched fragments of it into space. These fragments began orbiting earth and after a while gravity pulled them together to form the same moon we see on our night sky today.
