David,

Thanks for the information. You're correct. I have a very basic
physics understanding and I didn't know how the math worked out.

That's why I asked the question. Your explanation helped but I
have a few more questions.

How does the laser beam stay focused on the space craft? What
happens to the space craft if there is a malfunction of the
laser and the beam is interrupted?

When you calculate energy use, are you doing it by the second or
hour or day or just the initial need. You wrote:

"The energy to accelerate that 10 ton probe to 10% light speed
would be the equivalent of less than one day's operation of such
a system."

Once the craft arrives at the required speed, is the laser still
needed? In other words, does it require the same amount of
energy per second, or hour or day to stay at speed, or once it
gets to speed, does it glide to its destination? And once it
gets there, how does it stop and then turn around and return?

I agree that our visitors seem concerned with our nuclear
weapons. Why should they be if they don't live here?

Since they don't seem to be looking for a fight, it's much more
likely that their concern is generated by their knowledge that
we could destroy the neighborhood we both share.
