Humans Will Never Leave the Solar System(www.erscream.com)

Can’t even get my friends to buy a used electric car instead of a diesel. Which is an improvement in drivability and comfort - maybe a mild inconvenience for some. Imagine trying to make humans do larger changes in their lives. I think, this won’t happen voluntarily.

Long term, we must ban ICE vehicles regardless of people fetishizing them. EVs are cheaper to run but I would never own one or a hybrid with an NMC-based pack because it's just too dangerous in deflagration. LFP isn't good enough in terms of safety either.

When a vehicle with sodium, certified solid state, or ProLogium gets here, it resembles a Slate, and charges in 20 minutes at 100kW's, then I'll buy one.

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.

Yes, there are challenges. But a 'Rendezvous with Rama' approach, combined with humans in cryosleep? There's no scientific barrier with this kind of approach. Yes, it won't happen soon, nor will it take a reasonable amount of time, but it IS possible.

>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?

Yeah, and appearently we don't know how to shield from radiation either.

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

>the need to mass balance the entire rotating spacecraft in order to eliminate or minimize rotational imbalance causing gyroscopic precession/nutation motions and other oscillations of the rotating spacecraft;

I suppose this also involves mass-balancing the inhabitants!

What does the Coriolis effect mean in this context?

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.

Low quality bait.

If humans would be able to settle Mars and asteroid belt, there is no limit to how far you can expand onwards.

I wonder if even drone ships could communicate back to earth effectively if we sent them out so far. We'd probably have to wait forever for the robots to come back to find out what they learned, like waiting for ships to transit the Atlantic for news of America, you just hope they make it back.

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.

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...

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

True, a series of huge relays getting towed out in each direction you want to go. Last time I read into it they talked about near moon or planet sized communication systems.

Hard to take any article on this subect seriously when the author can't conceive of (and argue against the solution of) centrifugal force used for artificial gravity.

Arguments in favor of not destroying our home planet are a good thing, but the article is shallow enough to hurt the author's cause.

I don't think that was intentional, but it might as well have been.

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.
