What if?

Serious scientific answers to absurd hypothetical questions.

Some interesting questions:

• What would happen if everyone on Earth stood as close to each other as they could and jumped, everyone landing on the ground at the same instant?
• If an asteroid was very small but supermassive, could you really live on it like the Little Prince?
• How much Force power can Yoda output?
• If two immortal people were placed on opposite sides of an uninhabited Earthlike planet, how long would it take them to find each other?
