How is he going to learn if he doesn't try? This is a very safe hobby if one takes reasonable caution. I've performed a huge number of static tests and I had only one explosion (not unexpected, though) because of one special fuel mixture. Nobody expects to start with large engines. You start small and gradually increase the fuel masses and engine sizes. Don't be one of those nanny state guys that would ban sticks from children because they can impale themselves on them.

There is, but as I've said, there's too many variables when you don't work with professional... anything.

Kerbol is a point-like source of radiation, not a disk, therefore Moho will not be an exception.

There are too many variables. You need an experimental approach. Use different sized diameters and observe the effects at static tests. Start with the widest, then decrease the diameter. Expect explosive failure at one point, so take cover. Use a kitchen scale as a dynamometer. Secure the motor over it.

There is IONIZING and NONIONIZING radiation. Light is nonionizing radiation. Gamma rays is ionizing radiation. Lumping everything into "radiation" is just perpetuating the public ignorance. And no, "radiation" is not a public name for ionizing radiation.

Reinforced concrete and bricks are the staples of house construction throughout the world. Yes, the contents will start the fire, but if the house itself is flammable, not only will the fire spread faster, but the house will be gone, too. In concrete-brick houses, fires don't usually cause such damage because bricks are refractory material. Interior walls are usually brick, too, but thinner. Who cares about carbon footprint? The house has more quality to it and lasts for a long, long time. No decay. Construction wood needs to be treated to attenuate mold and insects. Those substances are volatile. Brick and concrete require nothing. Heat insulation is good but an useful upgrade is backing it up with rock wool from the outside.

Irrelevant if the threat of dying in a fire (because one is actually living in a damn PYRE) is much higher than usual. Bricks, people. Use bricks and reinforced concrete skeleton. Hollow bricks insulate heat very well, they are lightweight, and reinforced concrete skeleton is elastic and very strong.

Natural satellite. Not "moon", pls.

OMG that's amazing. Even the brightness seems to be better handled (I don't like light gray Ceres photos).

Apparently near. Or in apparent proximity. Or ostensibly near.

Why do you people build everything out of wood? It's fragile and flammable.

I post one video and I come back.

Neutron can not be orbited by an electron, at least we never saw that happening. Lone neutron has a halflife of ten minutes.

http://lisakimmorley.com/2015/02/08/a-matter-of-perspective/ That's... That will give me nightmares. Fungi are saprotrophic, meaning they consume decaying organic matter. It's very difficult to imagine such ecosystem. Maybe with two or more species of fungi, alternating in time, eating each other... There's no reason why such planet wouldn't have photosynthetic organisms. The whole point of the thread is discussing exotic metabolism evolved to thrive in said conditions. I don't know where you heard about that, but complex dyes are very sensitive to UV even though they can't deal with it in the usual fashion. That's why UV has a bleaching effect. It wrecks the conjugated double bonds in dyes which are responsible for their absorption spectrum. If an organism has evolved in such a way it collects as much as possible of the energy weak photons, then those systems will be more sensitive to photons of lower wavelength. They will have structures easily energized by high wavelength so that the efficiency of the whole process is high enough.

You mean 0 protons? No, that's not an element. Chemical elements are made out of atoms. Element with Z=0 was just a funny curiosity back when people didn't really know what made up the atoms. Some very old periodic tables included it.

Why would you assume the photosynthetic machinery would be made the same? It clearly needs to be more sensitive in order to be reactive with (probably) water when exposed to weak quanta. Throwing UVA, violet and blue at it should cause damage, just like some bacteria's molecules are damaged even by blue light. Compare it to photoelectric effect on metallic lattices. You can throw as many wrong photons at it as you want, but unless you get the one with enough energy, you won't eject an electron out of it. Near infrared is very abundant on Earth during daylight. Most plants repel it strongly so they look like this when the view is represented in monochrome. On a world where near infrared and red are the only plentiful light available, special dyes would evolve, being able to harness weak quanta of light. Bash their complex molecules even with small amounts of more energetic photons and they would get damaged. Compare it to a world orbiting a blue star where plants have evolved to endure lots of blue, violet and UV. Put our plants there and their protein machinery would break apart.

Elements are not our creation of mind. They are not arbitrary. Each element is defined by the number of protons in its nucleus. That's it. If it has two of them, it's helium and it will have specific chemical properties arising from the two electrons that are neutralizing its atom. Nobody can change that.

It should wreck their photosynthesis molecular mechanisms. The quanta impacting the molecules would bash it into pieces. On the subject of color, question is what the plants would look like under their parent star, and what would they look like under white light. There should be a difference.

For thorium to work, you need uranium. Thorium by itself won't do anything. The reason it's not used is way more complex than just weapons uranium/plutonium could offer.

Neutron star is not considered to be an enormous nucleus. That's just a curious analogy. It's being held by gravity, not strong nuclear force, and it has WAY more neutrons than protons. Also, in its depth, it probably has quark-gluon plasma. Here.

I think you're suffering from the "it's not Western, therefore it must be better" syndrome. Really, things are pretty bad there. Westerners can be lucky.

That's the 3D shadow of a 4D object. You will never be able to witness a true tesseract.

Darkness is less important here. The fact red quanta are less energetic is much more important. Life would need to adapt to these, absorbing as much energy as possible. Somehow I think these plants would look pretty close to pitch black in white light.

Nibiru is a nutters' imaginary end of the world thingy that they use to sell their kooky books. Case closed.

You've missed one crucial part.
