This isn't going to happen, for a number of reasons (all of which boil down to "It's dangerous, and these bacteria will kill their hosts"). Organic materials may "spontaneously ignite" when they ...
Greater endurance/stamina: A thicker atmosphere/higher oxygen levels Try a thicker atmosphere - or rather, a planet where the humans largely live at higher elevations. Altitude training is useful ...
The building structure may do OK, but the devil is in the details Gary Walker gave a good comprehensive description of what will happen to the structural materials - wood, brick, steel, etc. But t...
A first approximation Let's calculate surface gravity. Assuming an object of density $\rho$ and radius $R$, the surface gravity is $$g=\frac{4\pi}{3}G\rho R\tag{1}$$ For a white dwarf, $\rho\sim10...
According to the current models, the possible reasons for a supernova are thermal runaway or core collapse. Thermal runaway is probably your best bet, and happens when the core of the star gets ho...
Don't build a rocket ship. Build a good ol' fashioned airplane. He doesn't need a rocket ship. While Elon Musk is saying BFR can be used for point-to-point travel on Earth, the resources needed to...
Assuming that the dinosaurs survived, and somehow humans also evolved to what be what they are now, so dinosaurs exist alongside humans, humans would have hunted most of them to extinction, or at l...
Astrosynthesis is a nice generator that could fit your needs. It's a paid-for program, but it also has a 14-day trial so you can see what it has. It lets you generate stars as well as show them on...
I actually believe there are real-world Earth cultures you can draw inspiration from here. So you want a culture where hard work is considered a virtue, but you also want that culture to see being...
Practical issues with the whole cut-a-planet-with-a-beam idea. Your fundamental problem is that if you dig the trench by sequential applications of a beam with shallow penetration the time scale i...
Pure Knowledge != Knowing What To Do With the Knowledge The effect will be in some ways better and in some ways worse, but it certainly won't go away. Knowledge of a domain is not the same as know...
Going a bit more out there, say the aliens have discovered undeniable proof that the simulation theory is actually true. And they have figured out how to get access to some of the API from inside ...
An underground mine would remain undetected pretty much without any special precautions. Assuming they're not using heavy explosives, or anything like that, just drilling and excavating. The groun...
The holes could work similar to a hole tone whistle, which is the principle used for a whistling tea pot. The basic idea is that a stream of air is directed through one hole, and a short distanc...
This is a very deep question and from a formal scientific basis we indeed do not have adequate information to formulate an answer. However the Hindu philosophy (and some others) instructs us that ...
There is exactly one important cell - the Core The Core is what coordinates the super-healing. Every other cell is unimportant and will simply die when cut off from a "normal" body. They can't rea...
Deriving the radius The heliopause is a place of equilibrium, where the ram pressure from the solar wind is equal to the pressure of the interstellar medium (ISM). There are a number of sources of...
One of the moons is the size of Earth's moon, and has a semi-major axis of around 413,277 km. This gives it 12 orbits a year. The moons orbit is such that it is full while it is in the constellatio...
Hyperthyroidism It is a pathological condition caused by over-activity of the thyroid gland. The symptoms include Weight loss, sometimes significant, may occur despite a good appetite. There is ...
Narcolepsy is a pathology that lists sudden events of muscle collapse, akin to fainting, or seizure attacks, among its symptoms. As far as we know today, it does not seem to be entirely due to exte...
This could serve as a defense mechanism. Fruits are designed so that there's plenty of sugar for the seed when it grows, which gives it a better chance at survival. Even when an animal eats the fru...
Absolutely nothing That is, more accurately, that nothing has stifled their progress, and their civilization is right where it naturally would be. Well, natrually other than the fact that they wer...
Yes. There are sharks that live quite deep in the ocean; the goblin shark and frilled shark, for instance, have been known to live over 1,000 meters below sea level (Wikipedia claims great whites ...
Use a MOOSE Or, rather in this case, a COOSE, but that sounds less cool. MOOSE stands for Man Out Of Space Easiest. The general concept is a teadrop-shaped device, but it's inflatable. Deflated, ...
Why are transits so rare? Essentially, you want a low relative orbital inclination. A body's orbital inclination is the angular difference between its orbital plane and a reference plane. In the ...
