Document Summary

The final exam is 2 hours, about 60 mcq, and format is similar to the midterm. Bring a pencil and no calculators are allowed. It covers all the material in the course, including primers, and is weighted more towards material from after the midterm. Dark energy and supernovae: some persuasive new evidence for this effect has come from recent experiments to measure the distances to remote galaxies from their supernovae (kind of like. But supernove are visible for only a few weeks. They can be as bright as the entire galaxy. Only 1a"s can be used as standard candles. Type 1a supernovae which occurs in binary star systems where a large star is transferring matter to a white dwarf. White dwarves are unstable, and there is a very narrow range of stable masses so this process tends to be very similar.
