“According to Einstein’s special theory of relativity, it would require an infinite amount of energy to propel an object at more than 186,000 miles per second.”

I often listen to coast to coast (kook to kook), as it comes on for me at 7 AM, when I am waking up.
One morning they did have a reasonable NASA guy, a good old boy from Huntsville.
Unlike, the ET kooks, this guy gave very good logical explanations about future space travel.
Baring the unknown, worm holes or whatever, he said it could be possible to travel AT the speed of light, but pointed out that hitting something as small as a grain of sand at that speed would have the force of numerous nuclear bombs going off at the same time ( I forget the number).
Beam me up Scotty.

There have been serious studies of emitting a field to impart a positive or negative charge to dust in the path of a vehicle, and the opposite charge to the surface of the craft, making a "repulsor field".

I'm sure, however, that it would cause toenail warts, and contribute to next week's impending galactic disaster.
