Plate tectonics on earth are unique in our solar system and, as far as we can tell, in the galaxy, because of our oceans. Tectonic activity could occur on many different planet types, but Earth-like p …

The parameters are: Glass rain as a weather phenomenon Specifically, evaporation of silica at the equator, atmospheric currents carry it away to condense and rain. Mechanisms to make glass fall from t …

I think this is possible, but not in the way many people think of it. Forget lightning for a minute, and think of solar storms. In 1859, Earth experienced the most powerful solar storm in history. Tel …

For the physics of this world you should look at this question discussing how large a cube can be. It is not only feasible, it is almost certain that each face of the cube would evolve and develop uni …

I read through the answers and believe one thing needs to be said re: your “feasibility study”. It is physically possible, therefore “feasible” depends entirely on your level of technology. You are es …

I’ve gone and designed an entire earth-like planet where life had never evolved. Oil can be reached if needed—the purpose of this question is to find how far they can go and avoid it. (Oil is generate …

My organolithium environment planet needs to be chemically stabilized But I don't know which compounds could physically evolve on a planet to form an atmosphere and seas wherein humans would spontaneo …

My captains and pirates belt out lots of navigational commands and jargon, but none of it can relate to terrestrial maps. So I’m needing a system they use in transit and combat, that they will referen …

As for a reality check I have to start with your choice of stars. Our sun is G2-V star, which obviously has a temperature that puts the goldilocks zone at 1au. Your slightly hotter G0 star is giving …

My explorers will be using a torsion balance to weigh their new planet, which has no satellite, no magnetic field, and has a perpetual cloud cover. Is there a way to also use a torsion beam to determi …

Several factors can change your very complicated planet’s day cycle through the year. All of these require your planet to have a shifting mass area, and for your particular case, a very large mass are …

Hydrogen + Carbon + Heat + Pressure = Petroleum This question has a hard science answer as we have already produced petroleum in a lab setting. It has nothing at all to do with biomass. We have nearly …
