It’s possible, but the theory assumes we’re operating within the same physics, just different scales of time and space. Supposing there are other universes with their own laws of physics is rather arbitrary, and you could literally argue anything :)

I would argue a universe as a unit is a terrible candidate for an atom for a super-universe since our physics assumes it is a closed system. It would be neat if we weren’t bound by the heat-death of the universe and somehow low entropic states could leak back in. But that is all pure speculation and it cannot be proven or disproven from a scientific point of view.

Subatomic particles are still constrained by the same speed of light as larger objects. As you scale up the speed by which this recursive universe operates in, this limit becomes more and more significant, and fewer interactions can occur in the relative unit of time.

To put it another way, if this super-universe were to use solar systems as atoms, the speed of light would mean their timescale would be in the billions of our years to their seconds. This is derived from the picosecond delay of forces acting between our atoms and scaling up to the solar system “atoms” that make up our galactic neighborhood (10-100 light years apart). So solar systems couldn’t be atoms on this timescale because they would do little but coalesce some of the intergalactic medium and die in seconds.

The biggest issue with this idea is the speed of light. Atoms participate in a lot of interactions because subatomic particles act nearly instantaneously. There are millions of interactions occurring within a single proton at any given moment, with various virtual particles annihilating one another. Even if you increased the time scale, space is extremely large and there just wouldn’t be a lot happening in a solar system. There would be slight perturbations in orbits, and the sun would go through cycles quickly, but it’s extremely stable when compared to an atom.

Then if you look on a galaxy-wide perspective, the actions within the solar system are irrelevant to most of the galaxy. It would take a hundred thousand years for even the sun burning out to register, and more than likely it wouldn’t even matter for any other solar systems in our area.

Then if you look beyond galaxies, it’s mostly just the intergalactic medium being siphoned one way or the other, with only the random movement of galaxies determining anything.

Atoms have the weak and strong nuclear forces, as well as electromagnetism to create the complexity of the universe. Solar systems have little else but gravity, constrained by incredible distances even on the scale of the speed of light.

This is another one of those videos that spends a lot of time in lateral subjects without diving deeper in the main subject. I thought the idea that earth radiates energy made by biological processes fairly significant, and a far more interesting thought experiment to meditate on (Can we find aliens by looking at the thermal signature of exoplanets? Is there a methodology we can use to measure the efficiency of life?). Instead, it covers extremely basic principles of thermodynamics and heat pumps, which has been done to death in other videos.

Does science need some moderators? I am getting really tired of fluff and PR pieces posted here.

Source is article that references PR from EV manufacturer? Not science.

This is the correct answer.

But also how did he make that platinum coil? It has a melting point of 1772°C, so that can’t possibly be fused together with the tools he had.

If you have the pure metals, then you can join pieces by getting them hot. In the case of platinum, it’s highly ductile so you can cold work the pieces together. For the purposes of a catalyst, you don’t even need to join them together; the key is to expose as much surface area as possible. It would actually better to shave it into smaller pieces. However, the Ostwald process reacts gaseous ammonia at a specific temperature so it makes sense that the platinum is suspended as a coil; to allow even air flow and to only catalyze the reaction with the gaseous form.

The documentation calls for 10% rhodium, but that is apparently to prevent the degradation of the catalyst.

Didn’t like Cells at Work. Mostly because it’s high-school levels of anatomy and physiology. It’s fine for kids (although to be fair, even my graduate-level courses never talked about the primary cilium, and I learned about it by double-checking the show’s depiction of neutrophils).

Dr. Stone I liked much more. It captured the feeling of science, even when it’s generous with the capabilities of refining with primitive tools (e.g. getting access to pure ores is the only way to do anything they do in the show).

I’m surprised no one has mentioned Moyasimon: Tales of Agriculture. It is far more accurate to the science, is reasonably educational, and captures freshman-level college-life very well. I especially love how it will occasionally ditch tropes (e.g. the main character freaks out at the sexy dressed lady in the lab… because she is swarming with ,microorganisms from not wearing PPE).

On the other hand, most other science in anime is complete and utter garbage. The rule of cool does not work with science; you have to be a crazy old guy with tenure to ever get the expertise to do dramatic things (like the guy who proved H. pylori caused ulcers by drinking a culture of it or the dude who invented PCR from an acid trip). Even then, science is littered with the bodies of people who did such things (the guy who discovered methylene blue, the Curies, the victim of the Devil’s Core).

Most science in anime is some dude just hearing a cool word in english and using it in the vague way.

The trick is that people believe the bill of rights is the only protection afforded by the constitution. The framers were against such a list of rights because it implies exclusivity and may ignore the precepts of the entire document: that we’re all created equal and entitled to the pursuit of happiness. Surprise, surprise. As soon as landed white men were not the only ones covered by it, suddenly we split hairs about the amendments instead of the point of the entire document.

Wow. It’s insane seeing the “you” next to you.
