Real-life professors and scientists are grappling with real antimatter -- the particle physicists' "mirror image" of ordinary matter -- in today's laboratories to create the weapons and space cruisers of tommorrow.
Scientists are conducting research that someday may make space-refueling stations, and the possibility of interplanetary travel, a reality for all of us.
New research based on Einstein's general theory of relativity suggests that wormholes large and stable enough to allow intergalactic travel really can exist.
Freemand Dyson argues that interstellar travel is possible but will not likely occur within the next century.
