The most significant validation of Einstein’s Theory of General Relativity required the observation of stars that appear near the Sun in the sky. Due to the predicted curvature of space caused by the Sun, what were the stars expected to do when the Sun appeared near them in the sky? Why couldn’t astronomers just go out at any time and take pictures of this effect? So what did they have to wait for?  Did astronomers validate Einstein’s prediction?
An astronaut is in space at the midpoint between two stars of equal mass. Everything else is infinitely far away. What is the weight of the astronaut? Explain your answer.
