The Powder Toy

Another element idea: Oganesson-294, OGSN. This highly unstable element decays quickly into uranium, plutonium, and cesium, while releasing massive amounts of heat, neutrons and photons. It would hav...

No, as CO2 is not nearly as reactive as elemental oxygen. There are situations in which it can act as an oxidizer, but that generally involves extremely reactive elements such as magnesium or the alk...

A possible bug: the melted wax state for hydrocarbons acts like a powder instead of a liquid.

Another suggestion: HCl should not dissolve hydrocarbons, as it is not strong enough to protonate them. It can however form hydrochloride salts with certain organic molecules as well as molecules lik...

An additional effect could be electron-positron pair production if the photon energy is high enough.

One thing that might be interesting to see with the quantum physics would be high energy photons such as x-rays or gamma rays. These would have effects such as ionizing atoms or splitting hydrocarbon...

A quick question. How does the time dilation work? Does it take both a particle's velocity and gravity into account, or is it only based on gravity?

One other thing: I'm not sure if it's intended or not, but hydrochloric acid does not dissolve anything; the only reactions it has are the wet cell battery one, neutralization with sodium h...

The recent additions are nice. I do have a bug report though. If LN2 is spawned, the HUD labels it as "N-Type silicon" instead of "Liquid Nitrogen." Also, will there be other type...

It appears that carbon fibers have different thermal conductivities based on how they are made. Some of them conduct heat very slowly and make good insulators, but others conduct heat much faster. In...
