Clothes historians say corsets were mostly supportive and mostly very comfortable. But some people must have done right lacing to improve their figures.

I recently learned that there is no law that says corporations have to maximize shareholder value! That idea apparently goes back to a court case against Henry Ford where the ruling said CEOs should consider shareholder value as one of the important goals when making decisions. And then in the 80’s or 90’s when CEO pay began to be linked to the stock price, they started acting like it was a mandate from god to maximize share price. How Money Works has a great video on it called “The Dumbest Business Idea in History”.

Since spacetime is a single entity, as long as your time machine works by MOVING you through time, Newton's third law should apply for all the space dimensions, keeping you in the same relative place in space as everything else around you as you are moved through time. This of course, has other problematic implications, as it means you remain causally connected to the physical space around your time machine for the entire time trip. Thus, if you move forward in time by say 1000 years, but 500 years in the future the site where your time machine is standing is struck by an asteroid, your time machine will be affected by the impact. Time machines would probably need to be housed in deep, stable underground bunkers. Of course, if your time machine works by teleporting you through time, then all bets are off.

Interesting! Bras seem pretty normal today but perhaps future societies will think it was just men controlling women, kind of like how many see corsets- just a tool for the male gaze. I know women who hated wearing bras and said they were uncomfortable until they were fitted correctly YEARS later. Maybe corsets also had to be fitted correctly otherwise would be uncomfortable and restrict breathing. Are these clothes something a warped animal brain thinks it needs but doesn’t? Or is our brain evolved and these clothes fulfilling a utility? Another poster acknowledged that skeletons changed because of corsets, sort of like how cultures will put feet in wooden boxes to make them more square. Is that an evolved utility or a mental disorder in the species? Playing god or playing the devil.

@@desperadox7565 That's BS. Corsets from the 1800s were made to fit a specific person. They were made with specific measurements and with materials that would form to the body as you wore it. The reason why those women couldn't breathe in those corsets is because it wasn't made for them. The deformed skeletons you are referring to were likely from women who were lacing corsets too tightly which was an extreme practice even back then, or they were from women who were corseted at too young of an age, another extreme practice. Corsets were worn by all women in the Victorian period, even the working-class women who would work in factories or as maids, in fact, they made those jobs easier by giving much-needed lower back support. Modified corsets were even worn during pregnancy. The main reason why corsets are so vilified today is because the men of the time were afraid of them. Women were the ones who made and sold corsets, which gave them financial freedom from men. Men distorted medical information about corsets to take away that source of income and keep women subservient to men. The public hatred of corsets comes from misogyny. If you don't believe me and believe the doctors of the time then perhaps you should travel back in time and have them treat you for any condition. Are we really going to trust medical information from the same doctors who practiced bloodletting?

There are lots of great historical fashion channels here on yt that go in depth about why this misconception is so pervasive.

The planet question was probably inspired by the film Melancholia, in which it's a rogue planet from outside the solar system. Although the film Meteor had as the originating event, a collision between a comet and an asteroid sent the asteroid 'hurtling' towards Earth.

The question about green stars: my understanding is that the Sun is actually more green than we normally think. Between the atmosphere scattering the blue light away (hence the blue sky), and it being so bright we can't look at it without some sort of filter (such as hundreds of miles of atmosphere during sunrise & sunset) it looks more yellow here on Earth than it actually is.

Joe - first question. When going to the 1950s, take along a laptop computer with a VGA output and a charging cable and an adapter for an automobile cigarette lighter. For any other era, take along a fold up solar panel charger. BTW load up lots of thumb drives with lots of info. Can a language translating AI fit on a one terabyte thumb drive? One terabyte thumb drives are under $100 and thumb drives are still getting bigger and cheaper.

I have never seen a fashion trend in my lifetime that has been universally embraced. There are always dissenters.

It looks like a general formula for a black body curve is j(e)^-kln(x)² with k and j free parameters for adjusting magnitude and distribution density. When the green part of the visible spectrum is just about centered on the maxima, i.e. when you would expect to see green, green only accounts for 1/3 of the area under the curve with blue and red each also accounting for 1/3 if the area under the curve making white.

I'd recommend taking books, magazines, printed material into the future or past. A cell phone will be just a brick and you'll wish you could show them pictures of how it was/will be used. Imagine trying to convince somebody in 1950 how great this little, inert plastic and glass object can be. And it's never a bad idea to have some toilet paper along, just in case they've run out.

the ‘what would you bring time travel video’ is a good idea for a video

When a star's black-body radiation peaks in the green part of the spectrum, it necessarily also emits light across a range of other wavelengths, including yellow, orange, and even red and blue. A star emitting light predominantly in the green part of the spectrum will stimulate not only the green-sensitive cones in our eyes but also the red- and blue-sensitive cones to some degree. Our brains interpret the mixture of colors as white or yellowish-white.

I was wearing a pair of my 20+ year old vintage kikwear big pants yesterday!

Aren't stars colors also influenced by what gets absorbed? We use that to see what the composition of stars is, each showing unique spectrums. I bet a bunch of stars are green, but the intensity is so high that ours can't tell the difference between blazingly bright green and blazingly bright white. But that's just an sensitivity of the sensor issue, so lower sensitivity, higher intensity sensors would see more color in the stars. Or, the right filter would allow us to see the contrast.

When you separate photons out from the sun the most common are from the green part but rest of the photons make it all look white, the sun is white not yellow.

Calling the sun yellow is like calling space blue. Sure, it looks blue from here but there's a lot of stuff messing with those photons

There are two types of "yellow" light that we can see. One is light at the yellow wavelength, obviously, and the other is a mixture of many wavelengths with the average being in the yellow wavelengths, ie. red and green with some blue - which makes it whiter yellow. This is how TVs show yellow light too (apart from one model of I think it was Toshiba about 15 years ago that went for RGB and Y pixels instead of the usual RGB.)

I'd love to see a video on the 4B movement and what kind of benefits and consequences that could have for our future

for the light to be green it would have to have a very narrow peak centered at the green band of the spectrum visible to homo sapiens. the colors we do see are a mixture because of the broad (wide) spectrum emitted by some temperature of heat.

Adding to one of your answers... Forget not about "Rogue Planets," there are billions of them aimlessly going around, and will change course if they are captured by the gravitational pull of a star... (It would be a major issue for any species living in such a star system)...

The fact that everyday people are aware of different airplane models now really shows how bad Boeing has been messing up.

LOVED the questions this lightning round!

Regarding star color, I read that the sun is actually a turquise color but much of the green/blue hue is absorbed giving it tye yellow color

The lack of green stars can be partially explained by absence of green burning materials in stars. Joe was right, most of copper stuff burns green, but copper doesn't exist in stars. Stars fuse materials from hydrogen all the way to iron, but that's where fusion stops, as iron is too heavy and too stable, and by that point, the star usually goes supernova. Cobalt, nickel, copper and everything beyond that is produced during supernova explosions, not directly during star's lifespan.

On my TV(and with my eyes), some of the stars you showed actually looked green 😄

Whatever you bring in the backpack for that first question, should include a copy of "How To Invent Everything" by Ryan North. Even to 2100; we don't know when this slow spiral of society might suddenly collapse.

My vote is easily for an entire video on the time travel question. I'll bet you come up with something obscure but critical to have. And definitely antibiotics - either direction of time travel.

11:20 given recent events and insider leaks, I'd say that a Boeing Dreamliner 787 or 737 Max are probably actually higher risk than other aircraft. But also probably still lower risk than driving to your destination instead.

Based on the title, I can only think of a really old sci-fi book I read in high school. When Worlds Collide, and its sequel, After Worlds Collide. Definitely older books but fun ideas for what would happen with planets colliding or atleast passing close enough to cause massive disruptions.

Fascinating stuff!

Our sun is a mainly "green "star but yes the lower end photons over expose our eyes and cameras and the atmosphere skews things

As to fashion trends, I was told,ages ago, that cloths that used a lot of cloth (think bud baggy pants, long jackets, big hats) are worn when the economy is good. More modest, practical clothes are worn during hard economic times

Actually, it’s exactly the other way round. Roaring twenties and sixties: short skirts and dresses, thirties and eighties: baggy clothes, long skirts.

All the past ones, I would prioritize notebook and pencils so I could write down as much as possible. Probably a camera. And definitely the remote control for the time machine so I could zap back here before I get burned as a witch.

@ 12:31 The most plausible scenario is a rogue planet or moon enters the solar system and takes us out. Or maybe it disturbs the orbit of Saturn's moons or Jupiter's moons and sends one or more moons into the inner solar system.

I'd go back and try to prevent the fire that destroyed the Library of Alexandria. The amount of ancient knowledge lost is mind-blowing

Would your phone work if you took it into the 1950s tho? There'd be no internet so most of the features would be lost/useless. The antibiotics tho is something I wouldn't have considered, but is a wise choice. It's like a coworker I knew who said he'd hit up a library in the event of a zombie apocalypse. He'd want to know how to live off the land & make things that wouldn't be readily available anymore.

Good point about the phone in the 1950s. Though I guess the apps and games on it would still blow their minds.

@@joescott Agreed. The camera alone would amaze them. Just remember to take a charger with you 😊

I'm flying to New York in a month and after all the Boeing controversies I breathed a sigh of relief when I saw the planes I would be on are Airbus.

Quite coincidental you brought up the language change over time, saw an interesting video yesterday about just that - the creator shows just how much English has changed over the centuries, i believe he started around the 1300s & the pronunciation/accent alone was enough to make it sound like a completely different language. He proceeds through, jumping about 50yrs @a time to show the eventual progression to the SE British accent we're familiar with today So yeah, even if you learn middle English you probably won't understand it when spoken

7:06 there’s a misconception in manufacturing. When you buy a machine that replaces a human worker you have to do maintenance on that machine. Over time long term it ends up costing and not being free labor.

the problem is that it puts people of low qualification out of work. people who cant afford higher education to becone engineers etc to maintain a machine. it also means that people out there arent getting health insurance from these "low skill" jobs. the working class without high education will be wiped off the planet, and that is not good for capital from a capitalist pig standpoint.

Now the question is, like in the classic Hanna-Barbera cartoon Thundarr The barbarian what if a planet sized object passed in between the Earth and the Moon. What kind of havoc would that cause?

a 'close' encounter (asteroid) with Earth is a 'mere' 150 million kilometers (1 AU), a 'very close' is 150 million km (0.1 AU) - in comparison the moon is generally under 0.4 million km from Earth . the closest on record was 3,540 kilometers above the surface last year but it was tiny less than 10 meters across and stuff that small just burns up in the atmosphere.

It's Monday May 6th and I fully expected to see a new video from Joe this morning. Does anybody have any idea why a new video has not shown up? I'm getting your dad worried. You okay joe?

I'd love to see a video about what you'd bring in a backpack to different ages, sounds fun and interesting!

If I was time traveling, I'd probably bring things that have sentimental value to me. If I was going to an age before cell phones, I'd bring a lot of stationary to write letters (idk to who, but hopefully I'd make some friends along the journey).

I think what donasalyer meant was a collision of an astroid with a different planet/moon, affecting its orbit enough to interfere with the earth

The green star has a cool worlds video on this topic, highly recommended

nice unamed shout out to Nate Bargetze, "If I went back in time today with the knowledge I know now, I don't think I would make a difference.... I don't even think you guys would hear about it"

Would love to watch a whole video on the first question!

12:30 I think he's thinking about a rouge planet or other interstellar object. And such a thing could cause a lot of problems, especially if it was really small and really massive. A micro-black hole could be several times the mass of the sun yet only a few hundred meters in size. Such a black hole would only be visible if it had an accretion disk. It may be detectable through interactions with Solar System planets causing deviations in orbits, but these deviations would take time to detect, then more time to explain. It would be very likely that Earth's first detection of such a black hole would be from it's effects on Earth. Things like objects falling up, not down.

I think the question about planets and moon wasn’t asking about whether a planet or moon hit the earth….but rather, I think it was trying to get at the idea of “what if another moon or planet were hit so hard by something that it caused major bad things to happen to it…but would that affect earth too?”…like if another planet was slammed by a moon, and its orbit was slightly changed, what happens to us on earth (if anything)?
