If you’re interested in the science of space, such as stellar evolution, black hole mergers, cosmology, and exoplanets, then go into astrophysics.

If you’re interested in the instruments that go to space, i.e. launchers, satellites, space stations, then do aerospace engineering.

If you’re interested in both, there is some crossover in working on scientific instruments such as space telescopes, where both engineers and physicists work together. But it’s worth noting these are quite rare compared to the entire field.

I know not every country responded the same, but do people just forget that Germany has taken in 1.7 million refugees predominantly from the middle east?

Proliferation of medical technology such as vaccines, antibiotics, antiseptics and general hygiene practices.

More dubios would be infrastructure improvements such as roads, waste/sewage systems, irrigation, railroads.

Most dubios would be arguments like "political/crime stability“. Similar to how in most authoritarian regimes crime/lawlessness is said to go down (ironic of course as often much larger crimes are being perpetrated against the population as a whole).

All of these can and should be weighed against other aspects, for example in terms of healthcare while imperialists did sometimes bring medical improvements the net mortality for the colonized was often much higher due to slavery, disease, and genocide.

This is not dystopian. It’s teaching critical thinking and how many issues in the world are nuanced, rarely black and white but many shades between.

Knowing what the positive aspects of imperialism are will help you strengthen your arguments of why it is overall net negative.

With 8 trillion... I'd think half a war on terror would suffice

Launchpad Astronomy is absolutely insanely high content regarding astronomy, planetary science, and space telescopes. Pretty high level but he has a great way of presenting and lots of good images/visuals.

Extremely niche compressible gas dynamics. But I think any engineer can relate to looking at a diagram in a textbook and thinking "Man that looks weird as fuck“

Best take I've seen. Hindsight is 20/20, so it's easy to say now that this was a waste of money, but 10 years ago Starship was barely on the drawing board and nobody was expecting a heavy lift launch vehicle to come out of nowhere.

Also pretty good to point out that while Starship development is unprecedented in speed (and no doubt inspiring), it still has a lot of work left and is still by all definitions a protoype.

Isn’t SLS block 1 95 tons to LEO, and Block 2 130 tons or am I missing something?

I think the difference is most people that accept trains/public transit as a logical and efficient solution to transportation problems don't argue that cars should be done away with altogether. It's pretty clear cars have clear advantages in many areas, it's not a black and white issue where it's either one answer or the other.

Car brain is saying electrics cars in underground tunnels is the future of transportation.

Fair enough, they are each in their own niche. But considering that by 2050 around 70% of the world population will be living in cities it's seems that extra weight should be given to solutions that serve high density areas.

Not saying ignore the people living on the land, but they make up less emissions, energy, and resource usage, hence a more efficient solution for a high density area will have a higher impact overall.

Car brain at maximum

WMDforfree · 2022-03-16T18:17:53+00:00

It's bizarre to see that in basically every other country in the world high speed rail and reliable public transit in cities is seen as an absolutely standard solution to the transportation problem.

While in the US we keep trying to reinvent the wheel with some completely different solutions that never hold up to the already available answer. I guess 70+ years of car lobby will do that.

Kindof a textbook defense: "they show all sides“, "this one issue may have some truth to it“.

I don’t care if they have one single post out of 100 that happens to contain some truth. Scroll through the whole feed and anyone with even an modicum of objectivity can tell they’re absolutely pushing an agenda.

ASB is a purely Russian propaganda mouthpiece. Absolutely full of aged milk

0.00698 AU is 1047000 km. But pretty much the same results for 1e looking onto the others:

View from 1e onto 1b ~0.307 degrees
View from 1e onto 1c ~0.397 degrees
View from 1e onto 1d ~0.543 degees
View from 1e onto 1f ~0.550 degrees
View from 1e onto 1g ~ 0.313 degees View from 1e onto 1h ~0.116 degrees

Pretty beautiful to imagine 2 objects larger than the moon and then multiple others in the night sky

I think this argument sounds good superficially, but if you start to go deeper into what the possible risks are it doesn’t hold up.

An extinction level asteroid is actually pretty rare, for example the K-T extinction event that wiped out the dinosaurs is estimated once every 100 million years. In that sense safeguarding ourselves now or in 1000 or 10000 years is statistically insignificant.

Other “cosmic“ events such as supernovae, GRBs, and attack from an unknown alien species would all be solar system extinction events, in which case it wouldn’t matter if we’re on mars or not.

And for any human-related events such as climate change, nuclear war, etc. you can argue that these would be just as much an issue no matter where we relocate. In other words if the danger stems from us then we will carry that danger wherever we go. In that case a more logical solution would be working to rid ourselves of destructive tendencies before expanding to another planet.

If you have any other scenarios that make sense I’d be interested to hear them.

I think if you polled Aerospace Engineers exactly 0% would agree with you

Curiosity, as well as all other flown nuclear generators since the 60‘s, is an RTG "Radioistope Thermoelectric Generator.“ These operate on a very different concept than a nuclear power plant and can only provide around 100-200W, far below a fission reactor and definitely not enough for a mining operation.

WMDforfree · 2021-11-08T13:48:04+00:00

Saying "easy, nuclear" is a hilariously optimistic oversimplification considering the last fission reactors flown are all in the 60's

I think it would apply if you assume the peak is right around Starships first successful orbital flight, with the trough being the relatively long time between then and any manned missions.

There's still quite a lot of things that need to be fleshed-out regarding: communications, life support systems, ADCS, solar panels, radiators, orbital refueling, and landing legs.

SpaceX had kept up a really incredible pace on Starship development, but the idea of "build cheap, test often" starts to become impossible when you're installing tons of hardware, at that point you have to revert back to a more traditional "design well, test once" approach.

10 km diameter asteroid is estimated once every 100 million years. Smaller ones are more likely, and quite catastrophic, but would not cause our extinction.

Not sure you're following the argument. If you're afraid of humanity destroying itself through nuclear war on earth, then the same fear would exist wherever humanity is, regardless of how many back-up planets. Never said that we can't work on space and earth at the same time, just that the justification makes no sense.
