- Suppose 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 lightDistance Based on the graph above, the expansion rate of galaxies near us is than galaxies that are farther away. O faster slower O the same rate Velocity8) Calculate the velocity of a galaxy with a redshift of 0.37.
