Hi William,

Don't you get it? How does a rocket in space accelerate? - it squirts
MATTER in the opposite direction in which it wants to travel - right? The
maximum velocity attainable by the rocket is determined by the maximum
velocity of the matter it is squirting out.

Lets just say that the rocket is squirting mass out it's exhaust at 50,000
miles per hour. How could the rocket ever attain a velocity greater than
that of its own exhaust reaction mass? This rocket is incapable of a
velocity greater than 50,000 miles per hour.

Once again, using common Newtonion physics (every action has an equal and
opposite reaction) all the fuel in all the worlds in all the galaxies in
the whole (known) universe would not get you even close to light speed with
a rocket. The answer to your question should be clear... Rocket + infinite
amount of fuel = Velocity less than C.

What you need is an inertial drive that does not rely on thrust from an
expendable reaction mass. You should read Eric Laithwaite's paper on "Mass
Transfer". Then again, maybe you should start with a good text book on
basic physics and mechanics (seriously... I'm not having a go at you).

How can you disagree with Einstien, Newton, or any other fellow explorer if
you don't understand their theories or 'proofs'? Answer me that!

Bill.

P.S. Being called an "ignorant little puss" is probably a bit harsh.
Naughty Hexslinger! Hey Hexslinger, have you read Laithwaite's paper on
"Mass Transfer" yet? Laithwaite and Dawson figured out a brilliant method
of moving mass through space without resorting to an expendable reaction
mass and without upsetting Mr. Newton. Very interesting.
