So you set it up like a drug trial. First phase is really small, maybe 10 people to get dosing figured out. Maybe use some underprivileged people who would like a place to sleep and some money. If ...
Start with pulsar planet like the ones that formed around the pulsar Lich, but a little further out and tidally locked so that it becomes something like a hot eyeball world: Set the planet at ...
They could still tell the difference. A non-inertial frame involves acceleration of some sort, i.e. non-uniform velocity. Such a frame can certainly have uniform speed, but the direction of motion...
So in general terms, if the planet was like Earth in size and atmosphere, but had an orbit of .8 AU's instead of 1 AU, then the planet would have an average surface temperature of Kelvin: 322, Cels...
Learned behaviour. Like staking an elephant or Pavlov's dogs. When the dragon was young and more fragile it had a bad experience with some trappers who thought it would be fun to hurt it with fire...
Fight fire with fire. Remember, the fire-breathing dragon breathes fire for some reason. Even if the dragon doesn't realize that it breathes fire, the ability almost certainly evolved together wit...
Well, let's see how such a field would work. The Hamiltonian equations are $$\frac{\mathrm d x_k}{\mathrm d t} = \frac{\partial H}{\partial p_k} \quad \frac{\mathrm d p_k}{\mathrm d t} = -\frac{\pa...
The main function of clothing is to hinder the flow of heat. The last thing you want to do when putting people into cryogenic sleep is to hinder the flow of heat. Quite the opposite: You want to ha...
I'd be tempted to add comments that have a differing assumption to a couple of your points. If the scientist wants to improve humanity in general, step one might be to shorten the lifespan until h...
So you have to look at the different ways that energy is created. Most of the power plants we have boil down to something turning a turbine, which creates electricity. Coal, nuclear, etc all work b...
Atmospheric pressure 0.20% of that on Earth's surface? Take a look at the phase diagram for water: 0.20% of 1 atmosphere pressure means about 2 millibar. At that pressure, liquid water cannot e...
It's worth noting that even fairly dark objects will reflect some light. Unless the space elevator is completely absorbent (which is possible, as Vantablack is made of carbon nanotubes, but unlikel...
So the good news is that if you have the capability to construct a Dyson sphere, you have the capability of supplying it with resources. The sheer amount of matter needed is huge, and you'd need t...
Never. The problem is not being able to simulate a human brain; that one I consider possible, and probably even achievable on affordable hardware at some time in the future. The problem is taking ...
In a young planet, oxygen can be produced from water vapor via photodissociation, which occurs along a pathway like $$\text{H}_2\text{O}+h\nu\to\text{H}+\text{OH}$$ $$\text{H}+\text{OH}+h\nu\to2\te...
Sefa's answer is correct. Due to Newton's shell theorem, the force on any object inside (and due to) a spherically symmetric object of uniform mass density of exactly zero. The exact integration (s...
If it has a mane like a lion, this could be your heat shield. If it flaired out like a large umbrella and was made of a thin membrane or possibly fur, then it would block its body heat from whateve...
What a hurricane boils down to is a large difference in air pressure between two parts of the earth. Air from the high-pressure region attempts to move toward the low pressure region. Along the w...
Let's determine some basic parameters of the cluster. You say you want the stars to be 1-2 light-years apart. This is a little tricky because star clusters don't necessarily have uniform densities...
This has been proposed, believe it or not. Gravity is the weakest of the four fundamental forces, a mystery which has been dubbed the hierarchy problem. Several solutions have been floating around;...
No, it will not, no matter the changes done while keeping it a F-22 Wikipedia gives the data for the F-22 as empty weight 19,700 kg and a maximum take-off weight (MTOW) of 38,000 kg. That gives a ...
This is just a basic answer, but I used Samuel et al. (2014), who in turn cited the climate model of Léger et al. (2011) for a tidally-locked planet with no atmosphere. They give the formula for s...
This diagram from ck12.org shows where water ends up on Earth. Yes, this is dramatically simplified, but look at the side away from the moon. The implication here is that you will not only get an...
I don't think so, considering the distances involved, and the kind of density you'd need, unless a lot of it is "below the surface" embedded in the dark matter or in subspace. Maybe if the whole...
It could be possible for them to have a duel system (both gills and lungs), like lungfish. Some lungfish are able to run the two systems independently, so when they are breathing through their lu...
