Basic questions sometimes lead to incredible discoveries. I am not gonna act like a life coach -what a funny term- and try generalize this. Ask yourself these two questions if you have not already done, and contemplate. I will write in my next post about the answers, and the great mind who solved them.
1- The speed of light does not depend on the observers speed. What happens to an observer who is traveling faster and faster. What would an observer "see" when he is as fast as the light?
2- You are in an elevator. As it accelerates, you feel lighter. As it decelerates you feel heavier. What if the earth were one large elevator?
