- How do you effectively characterize the basic shape dependent properties for non-spherical particles? ExplainSuppose 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 lightQ2 Draw a Feynman diagram for each of the reactions below.
