Example text

Adding a third massive body, with its additional gravity, to the Earth-Moon system would change the system's dynamics in possibly chaotic ways. —they might choose to orbit the Earth in the direction opposite to its present direction of rotation. The tidal pull of the Mother Ship would then slowly serve to brake the Earth's rotation rate, lengthening the day or getting rid of it all together! In just such a way, the length of the Earth's day has been slowing due to the Moon's pull. Eventually (on a cosmic timescale), the Earth's rotation period would precisely match the orbital period of the Moon, so that one Earth day would be almost a month long.

I also believe that the questions that scientists and writers of science fiction wonder about are essentially universal and time invariant.

But there are other problems. If you want to stop as well as start, you have to bring along the fuel required to stop, which will be the same amount as was required to start. This means you need to bring not just nearly 100 times the mass of the rest of the payload in fuel, but 100 times the mass of both the payload plus fuel required to stop, or about 10,000 times the mass of the original payload. And that's just to start and stop! It doesn't include the fuel required for the return journey. This might suggest that we should not fool around with any propellant that travels slower than the speed of light itself, if we want to head out at near light speed.
