If humanity is ever going to advance beyond grubbing around on the surface of this planet then we are going to have to continue to create and master extremely dangerous things. Nuclear energy is one of those, both fission and fusion. If it's possible, we should also find a way to control gravity. The weapons applications of such a technology would be far beyond anything we are capable of doing with a nuclear bomb. Does this mean we should ban all research into gravity? Even something as innocuous as orbital mechanics can create a weapon much more powerful than a nuclear bomb. Get a small rocket engine and enough fuel out to a big enough asteroid and you could obliterate an entire continent and nearly all life on earth. Should we ban space travel and exploration?
