Sorry, I must be missing something, as this seams like you’re spending photons to move a package rather than just sending photons.
- credit_guy 8y agoThe problem is that all light sources are to some degree divergent. You can accelerate a package to a relativistic speed over a distance of the order of 100AU, which is thousands of times less than the distance to the closest star. Consequently, the light beam that you send spreads out thousands of times less over this distance. It’s still a lot, but you have a fighting chance.
