At two-tenths the speed of light, dust and atoms might not do significant damage even in a voyage of 40 years, but the faster you go, the worse it is--space begins to become abrasive. When you begin to approach the speed of light, hydrogen atoms become cosmic-ray particles, and they will fry the crew. ...So 60,000 kilometers per second may be the practical speed limit for space travel.

There is a terrific disadvantage in not having the abrasive quality of the press applied to you daily. Even though we never like it, and even though we wish they didn't write it, and even though we disapprove, there isn't any doubt that we could not do the job at all in a free society without a very, very active press.

Change means movement. Movement means friction. Only in the frictionless vacuum of a nonexistent abstract world can movement or change occur without that abrasive friction of conflict.
