Clash of the Titans: Andromeda and the Milky Way's future encounter

The Milky Way and the Andromeda Galaxy are heading toward cosmic confrontation as their mutual gravity guarantees a collision in 4 billion years time. What will happen? What will the new galaxy look like? What new discoveries have we made about the Milky Way and Andromeda? What do we know about the central black holes of the Milky Way and Andromeda? Will they merge? And what of the Milky Way's disk of gas and stars? This talk will also address recent discoveries from the LIGO observatory and future space missions that may be able to detect the merger of supermassive black holes in the centers of galaxies.
