Few people stretch the imagination as much as controversial theorist and activist Keith Henson:

“In 1987, he founded the Far Edge Committee to plan the Far Edge Party. Henson’s thinking was that the only way to see our entire galaxy before it died was to create multiple copies of himself, using such undefined technologies as mind uploading. The copies would go and experience the galaxy and then return to share their memories. And they would meet in the distant future at the other side of the Milky Way for a party.

About a thousand people were initially planning to attend this Far Edge Party, meaning that it would involve trillions of copies. Organizing the party therefore became a logistical challenge. The bean dip alone, organizers noted humorously, would weigh enough to form a black hole—a problem called “The Bean Dip Catastrophe.” ” —betterhumans
