Ed as I have commented before please do your homework about
space travel before saying really stupid things.

The time and energy involved in space are completely dependent
on the assumptions made.

Dr. Campbell an astronomer, in 1941 calculated that the required
initial launch weight of a rocket able to get a man to the moon
and back would be a million million tons.

Apollo got three guys there with an initial launch weight of
3000 tons. But Campbell assumed a single stage rocket, limited
to 1 g acceleration with much too low an exhaust veloicty using
a deadweight retrorocket to slow it down upon return... We used
the atmosphere to slow down, much higher accelerations and 3

All our deep space rockets use cosmic freeloading. Fusion
rockets produce particles having 10 million times as much energy
per particle as a chemical rocket. They are born that way not
accelerated... mass increase doesn't matter.

There is a 33 page chapter You Can Get Here From There in my
book Flying Saucers And Science
