As some who has basic know about stem related stuff this seems like a good start to fulfill my dreams of being an astronaut 😅

Here's an interesting question, do you think Mars was originally in the goldilocks zone but something happened either something knocked it out or it gradually fell out?? It would explain the idea that it once had water.

@@AmazingKevinWClark The core of the planet cooled faster than Earth due to its small size, which probably affected the magnetic field and all the things that result from not having a strong magnetic field. It's probably not the only reason, but I just wanted to give my thoughts.

You should react to how to move the sun stellar engines

Hot dang that take a long time but undertandebel

hehe fahrt

Kurzgesagt is part of a German TV Station even.

@@Baskemtball AAUUGHHHHH

Ah so the planet stays warm for longer, but it also heats up a lot less, which results in a net negative Flux in temperature?

@@randomaster138 Yes, the reflecting of the sunlight has a bigger impact on the temperature than the trapping of its heat.

not to mention all that fresh lava remodeling the entire, and I mean the ENTIRE surface and ocean beds of the earth.

isn't that why there have been ice ages? super volcanoes erupted and released an insane amount of ash.

@@itsnotthatwaffle1832 Yes you're right about that. That's probably what happened

Was going to say the exact same. Almost always double the amount of people show up and all of them are weird. It's why the word 'Lunatic' exists!

@@BlazeDeval The other times I saw it busier than normal, with less lunacy, were holidays and during the off-season when re-runs dominated TV. This was back before Netflix went streaming, but even now there is a certain segment of society that can’t afford it. Typically holidays would bring people that were lonely, wanted an excuse to not be with their family, wanted doctor excuse to be off work post-holiday, and the “this has been bothering me for a while but there’s nothing on TV to take my mind off of it, so I thought it would be a good time to come it” crowd. One of my personal favorites was the “I have a toothache so I put some cocaine on it and now my heart is racing” patient. He was a dick and wanted to argue about the tests and x-rays ordered for him…in the ED he brought himself to. It was the closest I ever got to knocking a patient the fuck out. Patients like him cause apathetic hospital workers, which is bad for the workers and worse for genuine patients. Luckily, I only had to x-ray his chest so my contact was shorter than the RN or PCT. If anyone reading this has experienced an apathetic emergency DR, RN, or XR, the reason is more than likely from having too many “patients” that don’t belong there, are uncooperative, and take attention or resources away from the actual patients in need. Rarely, it can be chalked up to a “bad day.” Most good healthcare workers can compartmentalize and show their “happy” face for their patients.

yep it is pure lunacy to deny it's effect

I think it’s also related to the concept of “nuclear winter” after a nuclear war.

it also happened after the Krakatoa eurption in 1883 which dropped the global average temperature by 1.2 °C

That seems more logical

I dont think people really think that it gets more mass. Being more massive is used in this case as a synonim for bigger not necessarly meaning heavier. Even though word massive stems from the word mass.

Similarly, the sun collapsing into a black hole wouldn't change our orbit.

@@michaczarnocki181 that's why he called it pedantry

I was about t write that second he said it. Where would he get new mass from? Lol;(

Why bring his race into it? Just because he’s aboriginal doesn’t mean he can’t be in a scientific field?

I am in no way an expert, but here are my thoughts: Greenhouse gasses have little to do with the sun. But rather preventing the earth from radiating heat outwards to space. But since the same goes for incoming sunlight, this alone doesn't cause a rise in temperature. (Or in other words: insulation works both ways) So my idea is that earth's OWN internal geothermal heat is (somewhat slowly) heating up the air/ground. Wich no longer cools itself like it used to due to the greenhouse gasses. But even if this theory is correct (it probably isn't). This wouldn't matter much, since it remains: "Greenhouse gasses cause global warming". Just with a different method/perspective.

@@suddeneevee9441 The reason why greenhouse gases work is because they are transparent in the visible part of the spectrum, aka the light that the Sun mostly emits, but they absorb in the infrared part of the spectrum, aka the part that the Earth emits due to black body radiation.

@@tonydai782 Oh yeah, I completely forgot to account for different 'types' of light being received/emitted. That would be a good reason for the gasses to work differently for inward and outward heat/energy flows.

You're out of your mind if you think it NEEDS billions of years to settle into a certain steady state temperature. Do you know why August is the hottest month even though the summer solstice is on June 20? Because the ground holds onto the heat so the time delay causes a phase shift of about 50 days. The thermal time constant however is nowhere near billions of years.

@@suddeneevee9441 That is literally what the greenhouse effect is. If you didn't understand that very simple concept then you literally knew nothing about it. The sun glows at a blackbody temperature of 5800 kelvin, and the Earth glows at 300 kelvin. Everything glows like the sun, at a frequency distribution characteristic of its temperature, the only reason some things don't appear to be glowing is because the frequencies of electromagnetic radiation they are emitting are ones you can't see.

ah,yea.I remember when mount pinatubo(Big terrifying volcano from the Philippines that eruped in June 15,1991) exploded the world cooled down a bit for a while

My mans just casually forgot about the year without a summer, SMH my head.

That almost the premise of a movie called Moon Fall but leter in the movie he gets wierd

The expanse is so amazing with some great physics, that would make a great video

Yes, that would be great. I'd like his thoughts on the Epstein drive

Sad the show got cancelled and probably won’t continue.. Also sad that Cas Anvar decided to ruin his career.

@@KSM2026 was and probably still is my fav character. too bad about the incident though

@@KSM2026 if there was a new season, new actors would probably be cast because it takes place 30 years later

would have thought the answer is actually just a sphere/ball .... a sphere always has a perpendicular angle towords oncoming photons no matter what direction on a micro scale, its why a shiny mirror ball you can see your face in straight on no matter how you turn it, then again thinking about it, that requires you hit it direct in its center, if you aim the laser on its side it will reflect to its side hmm

The next thing that would happen is that the alien would challenge a bunch of high schoolers to kill him.

Yet, the reaction wasn't great. Basically agreed with everything, except when he was wrong, or felt like complicating stuff. I'll stick to the original, than you very much. Generated a lot of views from the Kurtzgesagt (might wanna listen to the audio on a translator site) crowd, though, so definately worthwhile (for him).

would have thought its just a sphere, as spheres reflect photons back regardless of orientation, then again thinking about it, that requires you hit it direct in its center, if you aim the laser on its side it will reflect to its side hmm

I thought I heard that the moon was moving AWAY at 3cm a year as well

"The earth and the moon will collide"... I mean what the actual fudge? He might know something we don't, but that sounds like a red flag to me. EDIT: actually he clarifies that a bit later. Not the first time I reacted too fast :p

6:26

I believe it's a bit misleading to say that the Moon and Earth should collide in the far future. There are too many unknowns still. I believe the idea of the Moon falling back towards Earth is because of the tidal forces starting to disappear once the Sun starts swelling while entering its red giant stage. But then again, the assumption that nothing else would influence the Earth-Moon system externally for the coming 65 billion years seems a little far-fetched... Just because it has been fine for the past 4.5 billion years doesn't mean that it will stay that way. The Sun's red giant stage might swallow the Earth, a passing star might fling the Earth out of orbit, the Andromeda-Milkyway collision might have an influence, etc. On this scale, even the Universe itself is quite young for being "only" 13.8 billion years old. :')

Was a cool idea. Now that we could see ourselves from over 100LY away with webb... makes it kind of silly. Anyone who could kill us would have seen us already (by us I mean our planet's atmosphere). Which they could then see had life.

You answered your own question. An evenly distributed ring cancels out its own gravity.

No, it's moving away from Earth. Nothing to slow it down.

It is. He just made a mistake.

He specifically talks about this. When the moons orbital period matches the length of the earth's day and they become tidally locked the process reverses and the moon will start to lose altitude. To say it more straight forward than he did, the moons increase in orbit comes from tidal forces that allow the moon to take energy from the earths rotational speed, making days longer and the orbit higher. When there are no more tidal forces this will stop and the mood will start to lose altitude.

@@thecowilsoninc4175 Yes the moon is tidally locked to the earth. It however does rotate, once every 27 days the same as its orbital period. Since its orbital radius is increasing the rotational rate of the moon is slowing as well, since the orbital rate slows as it gets higher.

You dont need to be smart to be a scientist :)

@@teowiderberg3987 Uhm I think it's a necessary requirement to be a scientist.

@@teowiderberg3987 especially physics

Space elevators being stable are separate from rings being stable. Dlevator on the moon would be stable and rings would not be.

@@solsystem1342 Why wouldn't the ring be stable? I'm pretty sure the Moon itself itself is pretty far from Earth and it does have it's own Roche limit

Yes.

Im sure im wrong... but it would be cool if right before the moon hit a giant wall of water was pulled off

Not mich besides ego The bit at the end where he said he was waiting to see if Kurzgesagt would show the moon be torn apart sums it up. He's just looking for thing to complain about or excuses to go on unrelated tangents. And he can't even be right, like how he says the ash clouds would raise temperatures without bothering to check it out himself. Kurzgesagt does their research, this guy doesn't
