'The demonstration that no possible combination of known substances, known forms of machinery and known forms of force, can be united in a practical machine by which men shall fly along distances through the air, seems to the writer as complete as it is possible for the demonstration to be.'

Simon Newcomb, 1900

Interstallear travel is daunting, and the rocket that carried us to orbit (and hopefully other planets in our solar system) will not get us there within meaningful travel times. So, if known physics can't do the job, lets come up with new physics! In August of '97 I had the privilege of participating in NASA's Breakthrough Propulsion Physics kick-off meeting. This experience renewed my conviction that travel beyond our solar system is possible, and achievable within the next 25 years. Keep the vision alive!

AD ASTRA!

The following pages deal with the challenge of expanding human activities beyond our solar system and the propulsion technologies required to achieve this ambitious goal. All of the concepts discussed here are based on new insights and discoveries in the physical sciences. You will not find any material related to propulsion technology presently in use (e.g. rocket-propulsion). For a justification why the rocket does not qualify as a technological option to carry humans beyond the limits of our own solar system visit Marc Millis' website: Warp Drive - When?.
