but is it ethical / permissible to volunteer generations of your unborn descendants?

Just to add to examples in the post #12, there are "points at infinity" in projective geometry, e.g.,

That has no relevance to mathematics. The meaning of infinity depends on how it is formally defined.

I would add "at any given point". Our technological civilization grew in just about 3k years (give or take, add a zero, divide by ten...

Thank you very much for the suggestion. I will go through these. It's been very touching seeing the effect he had on this community by...

That's a description, not a definition. There is no single concept of infinity in mathematics. We might first encounter infinity in...

What's the longest you have ever lived like that? Even if we do build a "fusion drive", there is the problem of the rocket equation...

(1) Generation ships need not be "horribly inhumane". A space habitat hundreds of meters in diameter could be quite a pleasant place to...

Possibly, although I think natural evolution would be drastically reduced. Our medical technology would correct or compensate for most...

An unstated assumption in the line of discussion is that they exist simultaneously/now. Given that humans have only had the ability to...

so at best it would be like condemning yourself and your unborn generations to live out their lives on a cruise ship but with fake food...

Yes, although self-replicating robot probes rather than generation ships is the typical formulation. However generation ships are...

Even then - with a 100LY limit for communication that is 60k stars, so there could be tens of millions of technological civilizations in...
