Everybody Out

Q. Is there enough energy to move the entire current human population off-planet?

  • An absolute baseline energy requirement: 4 gigajoules per person. No matter how we do it, whether we use rockets or a cannon or a space elevator or a ladder, moving a 65-kilogram person—out of the Earth’s gravity well requires at least this much energy.
  • Launching all of humanity (total weight: around 400 million tons) would therefore take tens of trillions of tons of fuel.
