The Grand Collision
Patrick Moore anticipates the collision of our own Milky Way with Andromeda in two billion years' time. He explains the role that dark matter will play.
In two billion years' time our own Milky Way will collide with another galaxy, Andromeda. This cataclysmic event will rip apart the fabric of both galaxies, destroying stars and planets and sparking a shockwave of fiery rebirth. Eventually it will create new stars, solar systems and planets. Sir Patrick Moore anticipates this far-off event and explains the role that dark matter will play in this cosmic collision.
