Good point, you wouldn't care about the return trip. I am just too hung up on manned travel instead of pure information.

But assuming 100% efficiency, and assuming somebody could actually move something physical with a light beam, (I don't generally buy the solar wind theory) you would still be stuck at light speed maximum. That would leave the findings only to our future generations. Pretty unsatisfying.

I think I prefer reative propulsion which allows you to exceed light speed by any factor, but has the nasty consequense of time advancement for those left behind.
