I've sketched out an island, and then threw some tectonic plate boundaries on top hoping it would help me plot mountains. But the more I look at geological diagrams of plate boundaries, and read u...
What happens if Earth's magnetic field shuts down? How exactly does this impact humans, and how long before we need to make significant changes for survival? Does it make any difference if Earth'...
Theory If I am understanding this history of this correctly, in the 1920s the mathematical process of converting measurements with a certain amount of measurement error into numbers, then doing yo...
In my setting, one of the fallouts due to interstellar war between civilisations is that a planet's gravity can be removed. This capability is part of the setting's hyperspace mechanics so the exac...
The way this would work is by creating lasers & pumping them into a chamber where it can't escape. The power for the lasers to be created is made either with a generator or by charging using an...
I am trying to create "black magic" with a visual black effect with lore backing (it is for PC game). How can I create this effect, either optically or neurologically? I am not talking about hue ...
So I thought about how my dragon-like species would get it's wings between the arms and legs and I figured that this would be the evolutionary path for such a creature: Hexapodal ancestor -> Q...
The concept of utility fogs is actually pretty old. The idea is a swarm of fairly small micromachines (about 100 micrometers in length) that would be able to mimic most materials and objects. Each...
Imagine a far-future spacecraft drive that accelerates its reaction mass to a small fraction the speed of light (say, 1,000 km/s). Say the mass flow rate to the drive were 1kg/s, and say the reacti...
The planet is identical to Earth except for one twist. It is not axially rotated but has an elliptical orbit, causing longer, planetwide winters. I would just like to ask what the width of the hab...
I have done some research and so much contradict one another or I simply fail to understand. Do seasons occur on a tidally locked planet that isn't tilted on its axis?
In all honesty, probably the same way people select their partners now: partly by appearances, but ultimately by psychology or for financial reasons. Let's face it, your concept of the physically ...
I don't think things would change as much as you think they might. Looks would still play a part. Just because someone has great genes doesn't mean they take the time to maintain their body - sel...
Though maybe not the best solution, Depending on the environment, the Hair might just not be enough of a menace to be evolved away. Humans have advanced to such a degree that even heavily disadvant...
Ask yourself, why do humans have hair? Some ancestor of ours lost most of the hair on its body-- and men sometimes go bald. So why do humans have hair? It's probably because of sexual selection. ...
I think it is totally plausible for there to be planets with a single kind of terrain. For this to happen, the whole surface of the planet must be at roughly the same temperature (unless you're tal...
Everything might be pitch black. Because there would be an infinite number of orbitals in each molecule (instead of discretized solutions to the Schrodinger equation (i.e. Hamiltonian) you would h...
Machines are not in a hurry, impatience is one of those inferior human traits the machines want to eliminate. Therefore it is not necessary to have humans give up their life; it's sufficient to jus...
The same way you convince humans to accept pretty much anything: panem et circenses. Give them a comfortable(ish) life; public safety; fun entertainment. Some elements of the former, preferably in...
Preamble Lets start from the beginning here. The Alcubierre drive is a result of general relativity. This has what's known as a metric. Minkowski spacetime (lets call this 'flat') has the metric ...
I would suggest a large flying predator with a straight, thin, sharp horn. For evolutionary support consider a swordfish or narwhal tusk. The predator is evolved for a sneak swooping attack from ...
To accurately answer your question, you might need to use a stellar evolution code, either doing your own modeling or looking up existing data tables. I'd recommend the MESA code for the former app...
Elon Musk to the Rescue If you asked this same question 10 years ago, I would be as pessimistic as many of the other answers. But this is 2020. The Falcon Heavy is in production. Starship is on the...
Background: So this Kurzgesagt video talks about quark stars, and how two of them colliding could send strangelets flying towards Earth or the Sun. Now it's been said that since, theoretically (as...
First of all, in no way do I have advanced knowledge of particle physics, quantum mechanics, or any other necessary scientific concept for a full understanding of this question. Secondly, this is p...
