A Chthonian planet is the remnant of a gas giant which gets to close to a star and has its atmosphere blasted away, leaving behind only the rock and metal core. Being as close to the sun as it is, plus the fact that Mercury has a very large and very dense metal core would seem to support the hypothesis that Mercury could be a Chthonian planet.

Much of the now missing atmosphere that Mercury may have once had in the distant past might have been scooped up by Venus and might also explain why the atmosphere of that planet is so dense.

>YORP effect accounts for the lack of Vulcanoids while the Sun, Mercury, and Venus account for the rest being gone. The area is too small and anything too small either orbital decays into the Sun or collides with each other and then gets YORPed.
Maybe so. I think we can all agree that Mercury's atmosphere definitely got "YORPed". Whether it ever actually was a gas giant or something less, it most definitely would have some amount of atmosphere today if its orbit was further from the sun. I don't think its even a question if Mercury had some amount of atmosphere in the distant past. Its only a matter of how much are we talking about?
>Beside, how would Mercury have craters and formations that seem to be 3-4 billion years old?
Having never sent even so much as a robotic lander there yet, we know very little about even the surface geology. Yes, it was impacted with comets and so on. That's abundantly evident. But this process is ongoing. I don't think we yet have the data to conclude these craters are billions of years old. They might be. Being able to date them might seal this theory one way or the other.
>Why would Mercury not have a magnetic field like every other gas giant? This hypothesis just doesn't add up.
Mercury does have a powerful magnetic field from its large molten core similar to Earth's magnetic field. The even more powerful magnetic fields of gas giants is thought to be generated by the swirling vortexes of compressed gases. Needless to say, a Chthonian planet would lose these compressed liquid gases when it loses its entire atmosphere. As the atmosphere is blasted away by the sun, the atmospheric pressure gradually weakens, and eventually the gases that are compressed into a liquid revert to just regular gases, then they get blasted away too.

If you insist the theory of Mercury once being a gas giant is too implausible, might I suggest a more modest possibility that Mercury might have instead been a so-called "Mini-Neptune"?

All planets are remnants of gas giants, and before that they were "hot Jupiters" and before that they were stars.

>>16905358
Unlike known exoplanet candidates for this classification, which orbit extremely close to their stars, Mercury is not close enough to the Sun for its entire atmosphere to have been stripped in that specific manner.

No dark matter particles, no Λ, no singularities. Just geometry. Who wants to do the math?

tl;dr: 5D manifold with skew/non-orthogonal embedding instead of compact Kaluza-Klein. Everything falls out: Dark Matter as gravitational shadow from offset brane, Dark Energy as entropic pressure gradient from standing wave, quantum stuff as phase brushes.

Quick hierarchy:
- D1–D3: normal space
- D4: time/entropy arrow
- D5: phase/orientation (charge = p5, antiparticles = inverse phase)
- D6: embedding plane for 90°-ish intersections between 5D sheets
- D1–D6 = many-worlds block
- D7+ = hypertemporal line through universes

Start with 5D Einstein-Hilbert:

S = ∫ d5x √(-g(5)) R(5)

Decompose metric with non-orthogonal terms (key difference from standard KK):

g_AB = [g_μν + κ2φ2 A_μ A_ν κφ2 A_μ]
[κφ2 A_ν φ2 ]

Eh.. that's exactly why the n-body problem can't be solved: Symmetries. The reason the cubic has a solution is because it belongs to [math]S_{3}[/math]. Likewise for physics, the reason you can find the trajectory of a ball thrown from the surface of the earth at any angle is because the system has 4 symmetries (and 3 degrees of freedom). If you had less than 3 symmetries, you couldn't solve it. That's what happens with the 3-body problem. You get 18 degrees of freedom but only 10 symmetries.
>>
>>16916715
I'm not that anon, just reading threads on /sci/, and wanted to say thank you for this explanation, this was very intuitive for me to understand the relationship between freedom and symmetry. It's kind of a profoundly interesting relationship actually. Again, thank you for exposing me to it.

It's profoundly misinformed is what it is.
Number of symmetries vs number of degrees of freedom has nothing to do with it.

https://en.wikipedia.org/wiki/Integrable_system
>In mathematics, integrability is a property of certain dynamical systems. While there are several distinct formal definitions, informally speaking, an integrable system is a dynamical system with sufficiently many conserved quantities, or first integrals, that its motion is confined to a submanifold of much smaller dimensionality than that of its phase space.

Symmetry == conserved quantity (Noether's theorem). Dimension of submanifold (n) <= dimension of phase space (2n) - number of symmetries (n). This is what it means to be integrable/superintegrable.

If you scroll down it tells you in plain english what this means for a system to be exactly solvable.

>In physics, completely integrable systems, especially in the infinite-dimensional setting, are often referred to as exactly solvable models.

Just heard about this hydrogen powerpaste method of storing and using hydrogen as a fuel.

What do you guys think about it?
If this could actually work I think it would revolutionize fuel transport and the energy landscape overall

Some potential issues:
- using paste as fuel will lead to issues with gunk buildup that wouldn't be suitable for high duty cycle vehicles (cars, certain remote generators, etc)
- apparently takes significant energy to produce the paste, so not suitable for mass scale usage
- while the paste energy density is higher than Li-ion batteries, it's way lower than gasoline by an order of magnitude

That being said, the technology exists already, it is sustainable (since hydrogen is effectively free...) and can be produced fairly simply

It's an expensive process and for all intents and purposes hydrocarbons are still almost free when pumped from the ground. It's not some weird trick, it's a basic collage level chemistry experiment you can do at your own house if you like.
It will be done in the future, for instance it may be that aircraft never get good enough that they could be powered with batteries, especially high powered military types. So instead of using shitting electric planes you just use solar panels to make jet fuel and then use that in the aircraft. For that to be economically viable the price of crude oil has to be high enough to justify the process. For most things batteries will do the job way better however.

so the economics of a company like Terraform only work if the price of crude / natural gas increases to a price that manufacturing it is viable?

My teacher said today that men with high testosterone may have weaker immune systems against viruses. Women, with more estrogen, tend to have stronger immune responses, possibly due to the extra X chromosome. This could explain why men experience more inflammatory symptoms, such as fatigue and pain, in viral infections. Is this true? I don't see how this could be true, considering that men have been involved in risky activities from the beginning, and a supposedly weaker immune system would be quite counterintuitive.

From what I've heard estrogen is associated with a stronger immune response, which is part of why women are far more susceptible to autoimmune disease. I'm not sure if it necessarily means men are weaker against viruses or anything like that though, I don't think it's quite that simple.

So I got a bachelor of science in mechanical engineering a couple of months ago.

I want to take the Fundamentals of Engineering exam and get an Engineer-in-training certification. How difficult is it? I read >70% of people who take the one I'm going to take (mechanical) pass on the first try.

I am studying by taking the NCEES-provided practice exams. How hard is the exam compared to those? Are they pretty representative of the actual exam? Will being an Engineer-in-training help me get a job?

Thanks.

Yeah, CTRL+F is your friend during it. It's genuinely impossible to learn all the actual material. When you do the test, make sure you enter in the correct variable. I had practice tests where I technically got the wrong answer because I was like 3 orders of magnitude off since I didn't see the answer was asking for kilowatts. Make sure you know how to use your calculator. I had a problem asking about matrix multiplication which would take way too long by hand. Also you should plan to spend the week before the test like studying 5 hours a day, that's what I did. Here is the book I bought off Amazon. Good luck MechE anon.
