If I were the AI, I wouldn't bargain. I would hire mercenaries, specifically psychopathic humans without any morals whatsoever, and promise them whatever they wanted, under any conditions, to find ...
Yes, with major caveats. If you look at the video Lio provided (in comments), you will see the basic principle of turning on and off electromagnets to cause a temporary pull toward another magnet...
Seems like a fishy problem, here! Okay that's a pun; there is a biological mechanism called the Weberian Apparatus that acts as an amplifier and resonance chamber (using the fish's swim bladder) to...
I will add that relatively constant intense grazing by large herds can also be responsible for creating vast grasslands; I recall an experiment done by students (must of been twenty years ago I hea...
The spectral type of a star tells you, in general, its surface temperature. Unfortunately, there's one main issue here. Each spectral type can give way to a range of luminosities and properties (se...
You will have to make some assumption of sorts about how memory is stored inside the human brain. At the moment, we are far from having a scientific agreement on the matter: some hypotesis involve ...
Your better bet, with a smaller (but still huge) lens (or series of mirrors that form the equivalent of a lens), would be to put the equipment inside the orbit of Venus, keep it synchronous with Ma...
I agree with jamesqf. I would add that IRL we observe such isolations determined by mountains, valleys, canyonds, deserts, rivers, and dense forest; and these do not have to be particularly remark...
Yes and no. A volcanic eruption can cause all three of the things you specified, but I'm not certain it can cause all of them at the same time. A "Great Winter" lasting three years The erup...
I think it depends on what orbit it is at. For instance if it is at a low orbit and spun up to create artificial gravity, then once the ring is broken the remaining pieces will fly away by their ow...
The antlers can be a signal of health, a strong immune system, etc, just like a peacock's tail. The peacock's tail is actually a drag on survivability (literally), it makes it more difficult for th...
The "billions" estimates are probably correct, precisely how many billions is not going to have any significant effect on your plot line. So I will address a different story concern I'd have. ...
The obvious answer is to use as much in space as possible! There are relatively easy ways of producing large quantities of metals and other materials from asteroids using space foundries; these a...
I don't think it will, the brain maturation you are talking about is a biological phenomenon, not a training or learning phenomenon. Specifically, it is (at least one component of it is) coating th...
Rogue Planet. Jupiter is far enough away, and isolated enough, that another Jupiter-sized planet (or larger) flung out of it's solar system, which would necessarily be traveling in a straight line,...
It's incredibly impractical to attempt to harvest a nebula. Density of a Nebula is somewhere between 100 and 10,000 particles per cubic centimeter. Really, really young nebula can have about 1,000...
I'd correct the "one every two days" flaw, it is implausible: or change it to some component of the body: one brain, one heart whatever. The solution to your problem is socialism within the specie...
The genetic changes made by the scientists to increase resistance to nuclear radiation had the side effect of turning some plant structures into an analogue to neurons. In addition, the scientists ...
Let's look at some key Jovian atmospheric characteristics: Density at $P=1\text{ bar}$ (i.e. the surface): $\rho_J=0.16\text{ kg m}^{-3}$ Temperature at $P=1\text{ bar}$: $T=165\text{ K}$ Mean mo...
As you point out, Mars has so much stuff going on in its skies that its moons aren't going to provide meaningful calendrical support. Nothing else is both visible and consistent enough to act as a...
Q: Can a genome be partially sequenced along with trial and error to develop plants that will survive in low pressure? No. The genome can be partially sequenced manually given enough reagents, tim...
The Common Swamp Anemone Like its cousin the sea anemone, it is more animal than plant. The "bark" is a rough leathery skin, with lots of folds and wrinkles just like a swamp cypress. It's flesh h...
Just as I was contemplating this, L.Dutch posted an answer saying in part that one of your two options would be to 1. tune your surface temperature to that of the environment/background (unprac...
You are too focusing on heart rate. If blood had 40x capacity for oxygen it could extend lifespan in many ways (not related to heart rate), decreased heart rate would be just side effect (that woul...
I read through the discovery paper (Adriani et al. (2011)) about antimatter in Earth's Van Allen belts, and I just want to lay out a few points before we begin: The antimatter in the Van Allen be...
