An incredibly boring and unimaginative rehash of naysaying draped over a thinly disguised ideological agenda. Why is this on the front page? Edit: it's from a student newspaper from back in 2020, that explains a bit about the content but not why it's being upvoted. My guess is a bunch of people read the headline and confirmed their own beliefs.

The OP is citing facts. If you can't refute the facts I'd argue your comment is what's unimaginative.

>issues with microgravity I don't get it. You can make a ship big enough to house an entire civilization, for tens of thousands of years, but you can't spin it?

Even NASA considers rotational gravity to have huge obstacles rendering it impractical. https://technology.nasa.gov/patent/TOP2-311

I suppose this also involves mass-balancing the inhabitants!

What does the Coriolis effect mean in this context?

Things said before: Humans will never see the edge of the Earth Humans will never fly Humans will never get to space

Technically the first two are still true... No one has seen the edge of the earth because a sphere has no edge. No humans have ever flown, although we have created metal machines to do and when we pilot one of those we call it flying, which is sort of like calling piloting a mecha walking.

Earlier quoted context omitted.

Or you set up relays.

It is actually kinda hard problem. Anything a ship going away would drop would continue to move at speed it was dropped. And then if you are doing whole speed up and slow down they might even overshoot... You could keep launching them from solar system. But well might need lot of them. It really does get complicated when you start thinking of details and how mechanics work.

It shouldn't be that hard. It's basically just a network of satellites with directional antennas - tech we already have.

Objects will experience weird-looking 'forces' from the perspective of people in a rotating reference frame. For example a thrown object will curve strangely through the air. On earth the effect is so subtle that only artillery and weather are really effected I think. On a spacecraft which is much smaller you would experience an extremely magnified version.

As far as I can tell, there's no reason to believe that Coriolis will be harmful to humans beyond nausea and disorientation. If you ran quickly through the station it might cause you to fall. Possibly it might make machinery that deals with fluids more difficult to deal with. I would chalk it up as a relatively minor concern compared to other issues.

If you shoot something back at the same speed you're traveling to keep it "stationary", that's just called propulsion!

I feel like there might be slight issues on accelerating anything to same speed at interstellar distances inside distance of spaceship... You know equivalent gforces and that...
