Yeah, there’s 600 grizzly bears in Yellowstone alone.

I’m glad the Chinese Army is using tanks to return all the slaves to the Foxconn factory. I need a second iPhone so I don’t have to switch between WSB and Robinhood.

Reply to comment by Mrsparkles7100 in Star Trek is Motivating This Team of Scientists to Build a Working Warp Drive Spacecraft - The Debrief by Gari_305
I dug really deep into this, going as far as reading the original paper. Unfortunately Dr White didn’t actually build a bubble. His experiment created the negative energy characteristics associated with the Alcubierre Drive. No warp bubble was produced, his paper only covered a mathematical model which may assist in making a warp drive. The research is cool, but the experiment portion only confirms the results of existing research. Even more unfortunate is that a quick search of credible sources places doubt on his theoretical work.
The confirmation of Casimir Cavities is exciting, he should’ve left his results as is. Unfortunately his story keeps getting wilder each time he tells it. I don’t have much faith in his ability to maintain a narrative.
Original Article as you can tell it’s far from creating a buble: https://idp.springer.com/authorize?response_type=cookie&client_id=springerlink&redirect_uri=https%3A%2F%2Flink.springer.com%2Fcontent%2Fpdf%2F10.1140%2Fepjc%2Fs10052-021-09484-z

I did find a reference online of a camera catching a Russian on the ISS. Mark Kelly did spend a year in space, it’s definitely a possibility. Otherwise STS-47 had a married couple…

I’d recommend using JSTOR, every accredited institution has an agreement which will allow you to read articles for free. Just use your student login, and get instant access to all worthwhile journals.

Indigenous populations have been highly successful building civilization and large populations in Arctic conditions. Growing food is actually one of the easier problems for space exploration. The technology of getting there efficiently is the main hurdle

I’d argue no one lives in Antarctica due to international treaties outlawing it. Not that it has stopped people from trying to do so illegally.

I disagree, the future of space will be profit driven and has enormous economic benefits. Everything from the internet, cell phones, and the Fixed Programable Gate Array has its roots in tech developed during Apollo.
I believe the moon will eventually rival many Earth nations in economic output.
Something for thought:

Reply to comment by lawblawg in How could a planet capture an object as its satellite? by Atmo_reetry
I’ve generally seen ballistic capture done in terms of the final steps of a transfer orbit. It’s generally easier to explain gravity assist and ballistic capture (rendezvous) using the Hohmann framework.
PhyneasPhysicsPhrog t1_iwurph2 wrote
What you’re wanting to learn about is Hohmann Transfer Orbits. This is the process by which an object departs the Hill Sphere/Orbit of one object and enters that of another. In the case of interplanetary motion it accounts for the planets and host star’s gravity.
This is a good explanation with calculations: http://jwilson.coe.uga.edu/EMAT6680Fa05/Bacon/hohmanntransfers.html
I can also give you a Matlab and STK file with this built in.
