It will free man from the remaining chains, the chains of gravity which still tie him to this planet.
I remember my friend Johnny von Neumann used to say, 'with four parameters I can fit an elephant and with five I can make him wiggle his trunk.'
There are three stages in scientific discovery. First, people deny that it is true, then they deny that it is important; finally they credit the wrong person.
Having walked on the Moon, I know something about what we need to explore, really explore, in space.
Burning carbon-based substances like oil, gas, and especially coal, produces billions of tons of extra carbon dioxide each year. Methane gas from cows and pigs and other animals on our large farms ends up in the atmosphere as well, trapping more of the sun's energy as heat.
Time travel and teleportation will have to wait. It may take centuries to master these technology. But within the coming decades, we will understand dark matter, perhaps test string theory, find planets which can harbor life, and maybe have Brain 2.0, i.e. our consciousness on a disk which will survive even after we die.
