E=mc^2, the most famous equation in the world, describes the fact that anything with masspossesses a huge amount of energy, in principle – like, a 5kg cat has enough energy in itsmass to power the entire country of Norway for a year – if only the energy could somehowbe fully extracted from the cat.But it turns out that efficiently extracting energy from mass is a very hard thing to do.Anti-matter is, of course, the most efficient way of extracting energy from mass since,if you collide a cat with a cat made of anti-matter, 100% of the mass of the cat and anti-cat willbe converted into energy (powering Norway for 2 years).But the universe has almost no naturally-occurring anti-matter, so it’s not a practical choicefor generating energy, since you’d first have to use...
