Eh, that depends on your definition of 'fight', and if you have limited delta-V they may just be coasting. Realistically, space combat tends towards the winner being determined when forces are allocated, and the battle is when you resolve the inevitable (which, despite being inevitable, may be unknown to both parties).

Quite possibly, but 'normal vision' includes Telescopic or highly Acute vision that could spot ships, under the right circumstances, at quite long range.

Under typical circumstances that doesn't matter since the thermal IR sensor will have spotted the target much earlier than that.

Doubtful that the Mark I eyeball is used for detection in space. Cameras with telescopes, however, are likely.

Probably not. But I do remember "visual" being mentioned.

Hardly every single time. Or even most of the time.

'Visual' means something using the visual spectrum, not the mark I eyeball in particular.

Yeah, 99% of the time when physics says 'X is impossible', X is actually impossible. However, that's boring so no-one remembers those instances.

It's not what you think.

Then suddenly, those things that were impossible were possible. And everyone retroactively knew that, of course.

Like practical nuclear space ships producing enough Gs for passengers to be uncomfortably thrust into their acceleration couches? Or what about FTL subspace communications? For that matter, what about FTL propulsion at all? I recall reading a lot of science fiction about time travel, yet that still remains firmly out of reach, unless you've figured out how to create negative energy (energy is, after all, the generator of the time translation genorater in Hamiltonian systems).

If you'd like to link to primary research concerning the subject matter, I'll gladly read and consider it. Otherwise, I suppose I've said all I have to say.

Newton was wrong. Ignore that guy. Einstein was wrong. Ignore him.
And your contributions are?

Oh, yeah, you've really laid down the law. If we could all be so logical...
