- Don't use chatgpt will upvote and provide solution in Handwritten form neat and clean and please be quick as soon as possibleSuppose an alien race on a distant planet tries to send a message to us, with a laser (light). However, we were unaware that there is a stellar-mass black hole almost directly between us and them. How would this complicate our attempts to locate their position in the Galaxy? O Gravitational lensing would make the signal appear to be coming from a different location O The information carried by the laser (light) would be altered O It would not matter The black hole absorbs all of the light1. What is escape velocity? 2. What does it mean to have a binding energy? 3. Under what conditions would you have to achieve in order for a satellite to escape the gravitational field of another body? 4. Why don't astronauts feel the effects of gravity while in orbit around Earth? 5. Why don't we feel the physical attraction from people around us, if there is a force of gravity between every obiect containing mass?
