Last month, we as a species did something remarkable. We detected the presence of gravitational waves. While we all are celebrating and excited about the newest discovery of mankind. I could use answers to a few questions to be able to understand gravitational waves better and the importance of LIGO :-
- What if we didn't have LIGO ready before the wave that was detected passed through the Earth?
- What if later events were not as powerful as the colliding of two massive black holes that caused the wave that was detected?
- How did they exactly come to a conclusion that the wave detected were due to the result of collision of two black holes?
- Will they keep trying to detect more gravitational waves given that now we already know that these waves do exist? Why?
- I was taught that gravity is a force of attraction between two bodies acting on each other due to their masses and is directed towards their center and that explained most the things to us. But now with gravitational waves into picture. What exactly is going to change in the High School Physics where they teach about "Gravity" and everywhere else?
