Re: An idea for a stardrive (sort of)
I still think you're being far too optimistic about the far-end procedures. The ship may have a certain amount of manoeuvrability, but it is travelling at 0.8c (240,000 km/s), which must affect all sorts of things, such as the time between observing something and reaching it, and various comms issues, all of which must impact - possibly literally - the catching process and equipment.
The slightest errors in the velocity will change the time of arrival (affecting that perceived by the ship and that by the catcher differently). Yes, it's all maths and computers will be more powerful by then, but the tiniest error could lead to disaster.
