Like many children, when I was younger I dreamed of being an astronaut. The thought of flying into “outer space” to see all kinds of planets and moons was the coolest thing to me in the world and, honestly, it’s still pretty much the coolest thing to me in the world. As I got older, I began to learn more about the solar system and became especially fixated on something called black holes.
Black holes basically rule out everything that we could learn from physics. They are formed from the cores of supermassive stars once they collapse. And there’s something called escape velocity, which means that the larger the mass, the faster you have to travel to escape its pull. With that in mind, this means that black holes are so massive that nothing can escape them, including light. (To make this even more intense, please don’t forget how fast the speed of light is at 186,000 miles per second.)
To further understand black holes, we can look at dear Mr. Einstein who developed the general theory of relativity. This theory states that gravity affects time, which means that the more massive an object (a.k.a. has a greater gravitational pull), the more it can slow down time. So, obviously, since black holes have the highest gravitational pulse, the concept of time is completely diminished. Essentially, there’s no time.
