Black holes 2

•Millions of miles to only about ten miles.

•The temperature of the core will eventually become up to one hundred billion degrees.

•It will then supernova and blow off all the outer layers and the core will collapse into a single mathematical point with such gravity than not even light can escape, it is now a black hole.

 

Black holes

•A black hole forms when a star about twenty times the size of our sun comes to an end… this occurs when a star runs out of its hydrogen fuel. It will then shrink becoming smaller and smaller yet hotter and hotter. After just seconds of it collapsing in on its core it will change from having a diameter of (move to next post)

Theoretical time travel 2

Using a perfect orbit around a black hole the people would have the experience of time being slowed down because of the huge gravity. A sixteen minute orbit for the people onboard would be an 8 minute orbit.

Theoretical time travel

•Time travel is possible using an enormous spaceship moving at such speeds that in four years it would be moving at 99% of the speed of light thus making it travel through time.   (Moving at the speed of light slows a person’s perception of time thus meaning they could live for only a few years in there time but moving hundreds in Earth time)
