The star Alpha goes supernova. Ten years later and 100 ly away, as measured by astronomers in the galaxy, star Beta explodes.
a. Is it possible that the explosion of Alpha is in any way responsible for the explosion of Beta? Explain.
b. An alien spacecraft passing through the galaxy finds that the distance between the two explosions is 120 ly. According to the aliens, what is the time between the explosions?
One of the important ways in which the Higgs boson was detected at the Large Hadron Collider was by observing a type of decay in which the Higgs鈥攚hich decays too quickly to be observed directly鈥攊s immediately transformed into two photons emitted back to back. Two photons, with momenta , were detected. What is the mass of the Higgs boson? Give your answer as a multiple of the proton mass.
