> You have mixed up the basic premises, there is no laser in my original post, just starlight. You have also forgotten Newton’s second law of motion, “every action has an equal and opposite reaction”. The second ship would be slowed down by the reaction of the laser, and as these ships have to be light and flimsy to be pushed by the minuscule force of the light, that reverse force would not be negligible.

No I haven’t, I just didn’t include all the details. Sunlight or laser doesn’t matter, photons work the same. And the intermediate craft only needs to have a more powerful source of acceleration than the craft it accelerates and voila.

Your position is as ridiculous now as it was back in your previous stint posting here. There’s no real point in refuting all your flawed arguments again. If someone is curious they can just go back and read the old thread, or one of the many others we’ve had here picking physics-deniers arguments apart.
