- Cosmic_catastrophe abstract "The Cosmic catastrophe is a thought experiment in which the sun were to instantaneously disappear. The question is what would then happen to the earth and the other planets orbiting the sun. According to Isaac Newton's classical theory of gravity, the planets would immediately cease to move in circular motion, and due to inertia would start traveling in a straight line. Albert Einstein saw a deficiency in Newton's theory. Due to the finiteness of the speed of light, it would take a certain amount of time before the darkness from the sun's absence would reach the orbiting planet. Therefore, why would the planet instantaneously start traveling in a straight line before the information that the sun's disappearance has occurred.The Cosmic catastrophe thought experiment led Einstein to the invention of the General theory of relativity and the creation of the concept of spacetime. With the concept of spacetime, Einstein was able to fix the deficiency in Newton's theory. In Einstein's spacetime model, the disappearance of the sun would create gravitational waves in the spacetime. The gravitational waves travel at the speed of light, and an orbiting planet would not react to the sun's disappearance until after the gravitational wave has reached it. Only after the gravitational wave has passed the planet, would the planet start traveling in a straight line.".
