Wouldn't artificial gravity on par with Earth's gravity prevent many of the problems that they mentioned with colonizing Mars? Since Mars' atmosphere is unbreathable, you would have to live indoors. People would only be outside in spacesuits for short periods of time, and it sounds like short term exposure to low gravity wouldn't cause these adverse effects; only long term. If you spend the majority of your time under normal (albeit simulated) gravity, there wouldn't be any problems.
the way we create artificial gravity is to take an area and to spin it. The centrifugal forces acting on the objects inside the spinning area causes them to move to the outside walls and depending on how fast the area is spinning determines how many gs the objects are under. To make a base with complete artificial gravity on another planet would take a lot of power, and constant work to insure it doesn't brake down. It would be more practical to make a designated area for artificial gravity separate from where they live and work in case of it breaking and the power wouldn't be the same power that the base and equipment inside there would use.
@kanw, I imagine that by the time we're ready to colonize Mars, we would have solved that issue. It's just one of a thousand problems for NASA to solve in the interest of space colonization.
The idea behind the Mass Effect games is scientifically plausible. Energy accounts for a significant portion of the mass of matter. The Quantum Chromodynamic Binding Energy of the quark-gluon plasma inside of protons and neutrons accounts for 99% of their masses. If we could somehow alter that binding energy, we could change the mass of atoms. Also, the binding energy between electrons and nuclei creates an effect of negative mass. Artificial gravity is hypothetically possible if particle physics and quantum physics allow for an amazing discovery like that.
Yeah I thought it was weird she didn't mention that. I can't imagine NASA putting down a long-term base without a low rpm centrifuge to keep everyone at one g.
Would the adaptations gained from living in Mars's lesser gravity actually mutate someone/generations of people into a completely new species? I don't see why they would be anything more than a Martian race of Human.
I'm not sure, but I think even small distinctions can separate animals into species. What we consider "race" is more of a cosmetic distinction, and not a functional one, which is why we're all one species.
The idea is that you get speciation within species as a result of geographical isolation without the need for beneficial adaptations. Even if they are not selecting for specific mutants then the mutations that arise by pure chance could still eventually lead to speciation if there is no mixing of gene pools.
Well if you believe we evolved from apes then yes. If you believe that all life was merely spawned and each species existed spontaneously than no. The thing is, the process would take longer than an individuals life so either way we'll never know.
As someone who is constantly asking weird questions about shit, this is possibly the best show ever.
this one was super interesting, i love space! i had no idea people living on the iss had such issues. i know they have to exercise a bit but i always thought that was enough and they didnt have any issues when they came home.
Now I want a new Mars-Human species. Let's do this.
Like a Martian?
That space question is just begging for someone to mention The Expanse book and tv series. They actually use those consequences of physiology from living and growing up in low g as part of the social and political structure after humanity has started colonizing the rest of the solar system.
I'm not sure exactly how Sally imagined gravity spas being implemented to combat those issues but I thought that we don't currently have materials strong enough to create centrifugal "gravity" that would allow people to experience a full g, and definitely not in a size large enough to decrease the Coriolis effect.
The most recent episode even covered this topic with the Martians arriving on Earth.
We artificially create a full g and more all the time."Gravitron" amusement park rides generate around 3 g. Astronauts go through high-g training and the machines they use can go up to 20 g. The Coriolis force has no impact unless there's motion along the radial direction.
who the fuck asked that first question? why would you guys waste time on that one?? isnt that common knowledge?!
No, and there's no reason why it would be common knowledge. Most people don't learn how electricity works exactly in school and never encounter the problem or never think to ask. I hope you don't have that kind of reaction to people asking questions irl, that's how you discourage them from learning anything.
@LlamaLoupe "Most people don't learn how electricity works exactly in school" Wait, what? I would totally count it as common knowledge as well, we learned about that stuff in I think our 6th or 7th year of school. Weird.
These ads are getting a little annoying. I'm glad they moved them to the top of the show but they are just so fake.
You could just skip them?
Especially the mvmt watches, because they're overpriced junk, but that's how the world works unfortunately.
Skip it and quit bitching.

I always wondered as a thought experiment if filling a space station with water would prevent muscle loss if you were always moving against the pressure.
Obviously this creates a mess of other problems :p
But maybe going back to being an aquatic species is more beneficial to space travel.
Can we just start messing with genetics already? I want gills.
Kind of like indoor skydiving but in reverse and with water? Interesting idea
