Spoken like someone who's never read Tau Zero

Stephen Baxter's short story "Pilot" is another good one:

Nothing about Tau Zero refutes what the parent wrote. It reinforces it.
Plus, even Tau Zero's initial premise is a pipe dream.

I really find it hard to understand how people confuse science fiction with reality. I love Tau Zero - I first read it over 40 years ago - but it’s fiction, ffs.
Also they have trouble stopping in Tau Zero so they have no choice going further than they planned. It's one of the best sci-fi novels of all time, read it!.
That Bussard Ramjet, though, is thoroughly discredited. It can't possibly work. Hydrogen hydrogen fusion is a terribly slow nuclear reaction and if you had to stop the gas to give it enough time to react, you'd end up stopping the rocket not accelerating it. In fact, the most credible use of that kind of magnetic scoop is as a brake!
