I tried to do my best to keep it similar to the colors RALPH provided.

It would barely help with anything at all. Not only would it not solve the problem of total musculoskeletal atrophy, but also would strain some muscles too hard. You want to walk forwards - torso resists and wants to stay where it was. You want to stop, torso keeps going. Imagine all the cumulative stress in the feet. Grab a long pole (5 m at least), hold it vertically and try to translate it without tilting. Your hands will suffer a lot. Gravity coupled with friction force helps us with that by shedding our kinetic energy while we're walking, and when you want to start walking, you lean forward a bit, shift the center of mass and your legs follow the movement of your body that's "trying" to fall down. Walking is a complex thing and our brain does it "in the background".

Jets are sublimation. We're seeing highly exposed images of the comet. This is not Halley's comet or some sungrazer. Nothing wild happening there.

You do realize the forces of gases sublimating (total pressure is almost interplanetary vacuum) are negligible, otherwise, when applied to the whole area of the comet that's sublimating, it would cause the thing to behave analogous to an oxygen tank when you forcibly remove its valve by an axe.

Jets on comets aren't tiny. They originate from very wide areas sublimating into space. Imagine a town square with a pillar of light above it, visible only if your eyes adjust to the darkness. That would be the experience of standing on it. Philae is a 100 kg box the size of a washing machine. Yes, its weight is tiny, but you need lots of energy to accelerate it. In my opinion, there's a greater chance of it tilting or making a roll because of the instability of the crumbly terrain giving off volatiles, than it being pushed. If there were such concentrated jets appearing all over the comet, like in Deep Impact here: The surface of the comet would be shrouded when looked from orbit. It would look fluffy, foggy.

Ksp (NaCl) is around 37.5. It's quite high because of large solubility of sodium chloride. You can find it on Google if you remove all references to Kerbal Space Program by including -kerbal into the search field.

Am I fooling myself or am I really seeing enormous concentrical features around the moat? It reminded me of Valhalla crater on Callisto. I wonder what's on the other side. Perhaps this is the antipodes of an actual impact on the other side, frozen in motion, which caused the central mountain to sink into the crust? Any editing introduces new false data and removes original data, even if it's not useable (crappy huge pixelated things). I've just brushed it up until they were barely gone so yeah, nothing new can be seen, as you explained.

Wow, some morons in your stores... Water glass is like a hardware store commodity, essential when building chimneys and fireplaces. You can't use sodium phosphate for this. That will be a pretty awesome statue if you succeed. That's called pressure casting (DIY version LOL) and is indeed a thing. Try, but be careful. You don't want squirting molten aluminium in your face. What you could do is elevate the pouring hole so that excess metal will be the weight pushing the rest. It should work, but try to get some rock or glass wool to wrap around it. It usually comes in those fat soft slabs. Wrap it, tighten it with a steel wire and cover with aluminium foil, shiny side out.

No, I'm doing the opposite. I'm using the empirical data I have to make a hypothetical explanation. I actually did these experiments. All you did was use a very crude, half baked approximation and then pump out an explanation. How on earth did you come up with pumping 50 W into the wax, is beyond my understanding.

Then please explain the fact I've never experienced anything like this when I used to drop water by pipette into molten pool of wax in all kinds of candles just for fun? Surely there's a much greater chance of water going nuts if it's just a small drop and not a stream from the faucet, because its temperature will quickly change due to its tiny size. Also explain the fact that OP could grab the container without problems. It wasn't made out of asbestos.

No, we're testing the idea that it's a regular paraffin wax. Changing the variables ruins the experiment. We need a photo of the setup or else nothing matters. What I'm telling you is that, if it's a regular wax, you need some pretty extraordinary conditions, like a burner/heater under the wax.

All of the planets moved in their past. What matters is the present state.

Grab a thermometer and measure the temperature of the molten pool. I used to drop water with a pipette into it as a kid. Never ever even a sizzle. A candle simply can not heat itself up like that. BTW, OP should draw or take a photo of the thing in question.

I've done insane things in my life. All kinds of experiments, pyro ones as well. I can assure you that can not happen with paraffin wax. FFS, I used to extinguish candles like that. Yes, the ones in bottles. How on earth can a bottle heat itself up to those temperatures is beyond my understanding. The heat is being radiated, conducted and convected out of it all the time and the equilibrium can not be where temperature is so high. However, if it was not paraffin wax, but some mixture with other heavy esters, alcohols and fatty acids, it is a possibility that they are so volatile even some tiny initial splurt of water can cause the material to ignite and be carried by the agitated water (just by the force of the faucet) upwards. I can totally see that happening with very volatile oily stuff, but not regular paraffin wax. If it was that hot, he'd burn his hand when grabbing the cup.

Actually I think someone did think of this before. I just can't find it.

I know how the thing happens. I've also done it many times. Yes, it's the water that does it, obviously. Thing is, cup of water won't erupt into steam just like that. It needs heat. Lots of heat. Quantity a cup candle heated to expected temperatures simply doesn't have. It's a candle, not a cup of wax on a stove. You can't seriously compare firefighting experiments where a small cup of water is added into a pan of smoking oil with this scenario. OP's candle was not made out of wax. It was something more volatile, more flammable. No, small droplets of wax won't instantly ignite. They are not pyrophoric. They need flame.

Yes, sometimes certain regions have their own autonomy on these matters. To each country its own policy.

The Z-machine did a peak of 3.7 billion kelvin. Does that mean there's a huge crater where Albuquerque was? Temperature =/= heat. For actual paraffin wax, at least 200 °C is needed to reach flash point. If the wax isn't hot enough, not only water won't erupt, but nothing will ignite. I'm telling you this was not paraffin wax. It had additives and needs to be banned because it's a fire hazard.

You don't need that for plutonium. All you need is a glovebox with argon atmosphere. Hot cells are for fission products and other extremely radioactive bulk matter.

It's averaged and then applied for each country.

I did some processing. I've averaged the color and lightness of the region and used the average value to colorize the LORRI image. Also, some minor removal of those giant pixelated areas.

It's called summer. By using science I've been able to keep my apartment at 29-30 °C, while the outside local air is close to 42 °C because it lingers and absorbs ground heat. Properly measured, above this awful heated layer, current temperature is 34 °C. I'm in Croatia and I'm preparing lunch without gas or electricity.
