Three Key Elements
If you were researching something strong and invisible, how would you understand it? Scientists use light, gravity and escape velocity.
The reason light helps is that we know that light is the fastest thing on Earth, but even light can’t escape black holes. Light travels at 186,282 miles a second, so we know the speed has to be faster than that.
The reason gravity helps is because black holes have an enormous amount of gravity. Since everything that literally goes in a black hole gets sucked, scientists need to know how much gravitational pull they need to endure to research black holes.
The last thing that helps research black holes is escape velocity. Escape velocity is the speed that an object needs to break through a planet or thing in space. In order to research, scientists have to get in and out. These three sources really help scientists out.
