Hi Hilmar,

One more question about which I've wondered. Can matter be accelerated to near the speed of light in the vacuum of space? Assume for proposes of the question, that in a vacuum there would be no resistance to the matter or any other thing that acted upon the matter like gravity, other than the thrust of the rocket engine. Common sense would indicate that a steadily applied force, like in a rocket's thrusters, would over time accelerate the matter to near light speeds or beyond.

Regards,
