But Why?
United States
Приєднався 3 кві 2019
This is a channel dedicated to my 15 year old self who had a desire to learn, but didn't quite have the toolbox to fully understand everything around him. I create videos trying to explain things in a manner I believe I would have understood back then.
What Would it Take to Actually End the World?
I wanted to know what would need to happen to actually get pulled away by tidal forces.

Your Brain on Marijuana

How the brain works has always been a particular source of wonder to me. I was fascinated in how the dynamics of literal brain chemistry can change the entire computational process. Recently I have been wondering more and more about what exactly "being high" means. What is happening on a biomolecular level when we ingest cannabis? What changes in neurons that causes things to be perceived so di...
The Humanly Infinite

Today we explore this paradox of the ‘humanly infinite’ - the idea that there are concepts and numbers in our universe that, while they can be defined and understood mathematically, are beyond our ability to tangibly comprehend or visualize.

As a kid I had no idea what it meant when I was told "Mass is Energy" and "Mass can be converted into energy".

Energy Free Cooling through Physics

Did you know there's a whole branch of material sciences taking advantage of certain quirks of physics to create passive cooling devices? Because I didn't.

A Detailed Breakdown of Core Collapse Supernovae
Переглядів 501 тис.2 роки тому
The amount of energy produced from the collapsing core of a massive star is pretty inconceivable. The mechanism that facilitates the creation and distribution of this energy is just as wild. If you're like me you may have heard that Supernovae are the result of stellar masses "bouncing" off the incredibly dense proto-neutron star core. Like many things in this world, reality is far more complic...

Finally a science channel I love is discussing the show, I've always heard about the book but never got to reading it so when the show came out I was blown away by the creative ideas and scenarios that were present in the story and it's awesome seeing your channel discussing it. Would love to see more videos like thos
God just hated the Trisolarians 💀

But HOW?
The fact that it's a syzygy shouldn't matter either, it's just the distance between the planet and the center of mass of the star system that matters. So these forces would be applied constantly, not once in a celestial blue moon.
The white dwarfs could have caught each other in their gravity wells after becoming white dwarfs, so the red giant phase would not be an issue. And given enough time they could cool down enough to not be deadly to life on the planet. This wouldn't work in the context of the show, because cooling down to that temperature would take much longer than the current age of the universe, but it is within the realm of possibility in the far future. The much bigger problem is that such a system would not be stable for long enough for life to evolve on such a planet, and it may not even be possible at all when all the radiation from those white dwarfs is infrared.
Really cool visualization
What so poetic is that while it's out of reach by humanity, it's also right there in a simple deck of cards...bringing this full circle.
cabbage brain
Physics: intrinsic momentum Cats: hold my catnip
If someone right above the event horizon was trying to put a really long rod past it, wouldn't the observer pushing the rod down see the rod compress in the direction of the event horizon? Think about it, if time pretty much stops flowing at the event horizon then for the outside observer it would look like the tip just stops descending and quickly redshifts, but since time has physically stopped at the event horizon they won't ever see or feel it cross and it will have an effect like the object is compressing. Similar to how objects compress when moving at the speed of light.
I kept noticing things like that in the story but yeah, it's fun storytelling. =)
A three-body white dwarf system could physically occur if they were foreign stars, no? Three red giants become white dwarves in disparate systems. Two of them are then displaced from their systems (or vice versa I guess) by some passing of a heavy object like a black hole or your mum, and are later captures by the gravitational pull of the remaining one.
So something i have a problem with understanding are micro-novas, where white dwarfs accumulate enough hydrogen on its surface to trigger a critical fusion event in its atmosphere. I would love to see a topic of that and what is actually going on. Also i absolutely love your video on core collapse supernovas!
Umm.. does the outward centrifugal force not count as well? A planet orbiting a star is in equilibrium because gravity is balanced by centrifugal force, isn’t it? that’s already significant
This makes it seem impossible as who can imagine a world without pizza
Utterly fascinating (and very amusing) look at the problem. Cheers!
id then argue, a rogue earth-like planet was somehow caught into this idealized syzygy could humans somehow throw, or propel, earth into a system ??
Thank you for the great videos as ALWAYS!!! I always look forward to a video from but why to learn something new!
i was just emailing the "david butler" physics channel about this concept of sphere of influence when bodies pass near each other we need animations that help us dumdums develop an intuition for the maths of the phenomena youre a magician!
Neo'number : 52!^G64 🤔
So glad he didn’t mention curvature of space-time or any of other nonsense
Why, is it to much for your flat brain.
You will get more reach if you title it something related to the threebodyproblem I really like how the earthquakes were animated!
Awesome stuff!
So he gets 1k per hour in views
Incredible vedio I
Witness propaganda
I just dont get how a life bearing planet could form in a 3 body star system in the first place. Earth took billions of years of stability in the goldilocks zone to produce humans. That's the wildly unrealistic part
The God … duhh
Not the Pizzeria!
mama mia 😭
How will we practice to fly the Starship Bistromath now!?
Roche world are close enough together that it might be realistic to jump from one to the other (with a parachute)
These animations are super high quality!
HOLY SHIT JOJO REFERENCE?!!! "GRAVITY" "THE WORLD" ?!!!

The graphics for these videos are getting insanely good, would love to know how you make the visuals.
Blender, most likely.
That is true, but I do miss the old design of the "people"
I've been waiting for the next video. this is it
I really love that that the tone of this video is not the usual "media and authors are idiots and don't understand physics" but much rather "hey thats an interesting idea and even if its bonkers lets actually work it through and see what happens."
I genuinely can't stand people who look down on non scientists. As if scientists get everything right all the time
To be fair Remembrance of Earth's Past is pretty much just a bunch of cool big ideas explored, somewhat strung together with a narrative.
I have somehow opened this when it has no views or comments. Never done that before.
Congratulations 🎉

Okay the x-ray image will haunt me while sleeping 😭
*A big problem with that video is that the "4th dimension" of what is WRONGLY called "time" is actually simply the conceptual "sequential line of 3D movie frames" (conceptual "frames" of spatial configuration) and THAT is why everything is said to be moving through that dimension at the same speed. Because obviously everything inside a frame of movie film is moving at the same speed through a movie projector.*
*After that video, now wonder if that is simply a theory based on BS*
*Extremely ignorant video by not talking about papers and experiments by Poincare and Lorentz that PRECEDED albert arse-stain the plagiarist!!!*
*That equation was PLAGIARIZED by einstein (from De Pretto) and albert arse-stain also PLAGIARIZED his 1905 paper from numerous non-jew scientists that he somehow “forgot to cite”, including Lorentz and Poincare and so on. Literally was reading science journals instead of working at the cushy job his jew friend got him at a patent office (that he apparently wanted as a way to “be inspired by” people’s patents also).*
