Think BIG. Now double it.
The particles of light hitting the sail will give a force. So, estimates as to the size would be measured in Acres. But they are very thin, a couple of thou., so they can be packed up correctly to fit in, shall we say, a “Buildable” spacecraft.
Think not of the weight / mass and speed of the incoming, it is on a path which is pulled by gravity of the sun, and only a slight force is required to overcome gravity, as you clearly demonstrate by shining your pants right now.
Some Satellites already use them to correct minute trajectory alignments. I think the Japs have launched a bug-un too.
Gravity, the most powerful force in the Universe, yet we can very easily overcome it. Pity we don’t actually know what it is.
😮 wrong ! physics , Go read . 🙂
