Hey 👋 Joe lately I’ve been wondering about how mold can effect a human Neurologically. A friend told me it’s what causes old abandoned houses and buildings to feel haunted and why you might feel as if something is watching you or a presence in the room as well as seeing dark shadows in the corner of your eyes but when you look nothing is there. That sounds wild to me.

[@somebodyspecial0100]

This is fascinating! It’s a shame Joe won’t do a video on this topic.

[@LeBatteur]

I’ve never heard of anything like that, but it is well documented that certain sound frequencies that are undetectable to you, but very detectable to your body, can cause major anxiety and dread in people. Oftentimes old machinery and locations like tunnels or crevices that wind can pass through can cause this effect.

[@rodrigosilvero5749]

​@@LeBatteur yeah sure it's wind. Upstairs in the house?!?😮

[@wolfiemuse]

@@rodrigosilvero5749Yep. It’s easy to forget, but air isn’t this still thing that just sits still when you’re inside a house. Air is a liquid that flows and has currents and eddies like every other liquid that flows. Also the human mind is an incredible liar - we are extremely good at convincing ourselves of something that never happened, but our brain THOUGHT it saw something and therefore you “see” a shadow in the darkness or something out of the corner of your eye when really it’s just your brain fooling you. Apophenia is everyone’s new word of the day

And yeah temperatures of -30 and 40 are not supper uncommon in big american cities like Chicago. I guess just goes to show how big US is, where the South US rarely sees freezing temps, but in the north that is pretty much common place. I would say Russia is probably the same but I think all of Russia is in pretty high latitudes so everywhere there gets pretty cold lol.

Watching Avi Loeb's evolution from 'respected Harvard astrophysicist' to 'guy who talks about aliens on KZbin' has been one of the many adventures of the pandemic.

[@realzachfluke1]

Dr. Loeb is one of the people who truly have my deepest respect. And it boils down to this: he noticed a _problematic conservatism_ persisting among the mainstream scientific community, including his own colleagues in the astronomy community, that had clearly in Avi's eyes been resulting in anti-scientific outcomes, a bizarre, sheltered elitism that created a rift between the public and the scientific community, between what _the public_ (who tend to be the funders of scientific research one way or another) was interested in, and wanted answers to, and what mainstream, award-winning scientists thought was worth studying and looking into-not because they were or are bad people, but because they've gotten caught up in things like their academic bubbles, or their comfort zones, or their preconceived notions of what we can or can't find out there. And his response was to use the positions he's worked incredibly hard to end up in, and the respect and reputation he's gained in the mainstream community in the process, and of course _his voice,_ to change that. To *correct* the problems that have been stifling new discoveries for decades, and that even led to the outright bullying of scientists (and people in the general population) who wanted to scientifically pursue ideas that weren't considered testable, or realistic, or were seen by fellow scientists who believed they knew better to be _not worth our time_ to check. He is leading by example, and it's absolutely been working, so for that, he's more than earned my utmost respect and admiration. Period.

something we talk about in canada a bit (because of the differences from east to west) is a wet cold vs a dry cold. a dry cold is like walking into a hockey rink. np. A wet cold feels like you can't get away from it. I'd imagine it has something to do with heat transfer and the moisture in the air. The temps aren't as low but you feel it easier

[@MostlyAwesome]

OK I have to say my patreon money was totally worth the Shawshank Redemption reference

[@KingNedya]

@Naturally Perfect ...What...?

[@KingNedya]

@Naturally Perfect Your comment just seemed entirely unrelated to the original comment, with the sole exception that it described (in detail) your experiences with a film that the original comment referenced, and then later in your comment it became illegible to me.

[@KingNedya]

@Naturally Perfect It's not Mostly Awesome's fault whatsoever; they were just saying that their Patreon money was well-spent, because Joe made a Shawshank Redemption reference. "Patreon money" is money spent on Patreon, which is a site where people can choose to pay a subscription, and the money they spend on the subscription goes to a person of their choice, in this case Joe, as an additional method of supporting creators they like. The people paying the subscription are called "Patreon supporters", or just "supporters", because the money they spend supports the creator of their choice. In exchange, supporters usually get special benefits in comparison to everyone else, usually having their name featured in videos (that's what the names that scroll at the end of Joe's videos are) and/or being able to see videos early, before they are posted on KZbin. It is very common for KZbinrs to have a Patreon, so that they have a more consistent and reliable form of income, because KZbin isn't exactly the most consistent when it comes to how well your videos do, and therefore, how much money you make.

[@staticgrass]

Joe Scott: What would happen if the sun didn’t pop up one day? Scotland: Laughs in Scottish.

[@jillengland3277]

The half life of heat in the atmosphere is about 15 days. So take your current temp and calculate. The declineing temp will take short pauses at the vapor, liquid, ice transition points but after we hit the CO2 freeze point in the first 6 months the surface would be pretty much uninhabitable. As long ad the sun is out the surface will continue to approach MBG.

Hi - just wanted to clarify - though Thiem Hoang currently works as an astrophysicist in Korea, he is actually Vietnamese. I think "a Korean astrophysicist" may leave the impression that he is Korean when in fact he is Vietnamese. Though this may seem like a trivial detail, I think for countries that are often labeled as "third world" or "developing," it is important to point to individuals or other successes that may help combat that narrative.

[@washinours]

The fun part about Omuamua is that this object estimated to be between 100m and 1km long sped through our system at about 85km/s and we only spotted it *on its way out* Would've have sucked if it was on a collision course with us, blinded by the Sun we basically would've learn about it on impact.

@@dundermifflinity I think the way it is it's more in line with our initially always naive approach to science and knowledge and the way reality usually evates that: 'You came here for answers? Here they are. What, the answers just gave you more questions? That's the universe for ya, kiddo.'

My best answer: Ball bearings. It’s all ball bearings now. Come on guys it’s so simple.

[@thisaccountisdead9060]

Actually, if you can figure out what is the optimal size and number of ball bearings to spread a load over the largest surface area (caused by stress deformation of the bearing with the contact surface) for a given space allowed for the bearings to fit under a given load. You can probably figure out anything...

Talking about gamma rays, I work for a university physics department on a free electron laser. We create gamma rays. We also have a lot of spiders that make themselves at home around the ring and the two rooms the gamma rays go into. I always wondered, if I get bit by one of those spiders, do I turn into Spiderman, The Hulk, or a Spiderman/Hulk hybrid? What do you think?

Every now and then I think really deep on something, like this time was black holes and damn are they terrifying. They can be many times the size of our planet, and they're so dense that they can trap literal light. If one was close enough it would literally just tear our planet apart. That's crazy and terrifying.

[@ShelburneCountry]

No. They spent eons building the Dyson Sphere. We only lost sight when they put the last panel in place!

[@blacksmith67]

Maybe 75Ma ago they had only half built their Dyson swarm and the built part just swung around to the side that we would be on 75Ma later.

Maybe it was a significant period of time, and we only saw the last panel put in place. They were probably busy making it since before we started recording.

[@AnthonyIlstonJones]

@@Bob_Lob_Law Would be a hell of a job building a Dyson sphere around a star that big, not necessarily a good choice. And to the OP they're unlikely to be natives evolving to that level around such a young star, or do you think we're late developers?

Why is Omuamua's movement considered so mysterious? Given the trajectory for it that was on screen, it seems to me like it just got caught in our sun's gravity and got a speed boost from that.

So you think that in roughly 10 seconds, you, some random person, can solve the mystery that’s eluded actual experts in this field… I would assume that if the answer was that simple, it probably wouldn’t be a mystery anymore…… particularly to the people who have dedicated their lives to studying this sort of thing…
