YouTube Description

as posted by the channel

Have other universes collided with our universe, leaving cosmic "bruises" on the cosmic background radiation, and what does that imply about our expanding universe? In answering a fan's Cosmic Query, astrophysicist Neil deGrasse Tyson and Eugene Mirman ponder the possibility of cosmic collisions and discuss the physics of the multiverse.
