As @vodolaz095 mentioned, this isn't something that could happen quickly - @John O's answer points out a lot of the issues that show up there. There is a parasite that does something marginally si...
It wouldn't. The field of a magnetic dipole has a strong radial dependence; it falls off proportional to $r^{-3}$, where $r$ is the distance to the dipole. The values you list are the strengths of...
If the ends of the wormhole can be moved, then maybe terraforming Let's imagine your explorers have travelled to a new solar system. It's got a type G sun, pretty much identical to our Sun. There ...
I've read the paper written by the researchers in the article you reference. I've also read its follow-up: "Creating a Traversable Wormhole". Disclaimer: I'm not a physicist, and much of it goes o...
This has actually been an area of intense research for decades now. Astronomers are quite interested in the distribution of stellar masses in a variety of different galaxies and clusters. The preci...
This seems like a great time to check out https://azgaar.github.io/Fantasy-Map-Generator/. If you can turn your base map (coastlines) into a digital image, you can upload it there, start painting i...
Y'all are making this too hard. The OP said the AI's aren't androids. That means they have physical limitations, even if they're tapped into most of the data channels. Simply don't give the AI's ...
How can a dragon prevent the animals from registering him as a threat? Don't act threatening. Animals aren't stupid, and running away takes energy. I believe many/most prey animals will allow...
This answer contains two answers, rolled into one. First the Moon, then the Earth. The Moon: The Moon - in short: Lots of green and black crystals, but because of the sun they look a bit bluer t...
There is nothing inherently dangerous about matter that has been created out of nothing (indeed, that's how all the matter around us has originally been created). However the method itself can be d...
Kugelblitz. If your weapon is mass/energy then yep you are in the right territory. If it's matter in a particular configuration (a complex piece that took hundreds of thousands of work-hours to ma...
No, there's no such element that would justify this sort of attempt. We have data on the composition of the Sun's photosphere, one of its outermost layers. By mass, the solar photosphere is 98.3% ...
We can treat a planet as a magnetic dipole. In this case, the strength of the field scales as an inverse cube law (rather than the more familiar inverse square law), with some angular dependence. A...
By being an island arc volcano. You seem to be referring to hotspot volcanoes, which are fed by abnormally hot regions of the Earth's mantle. As the continental plates drift by overhead, the area ...
Resonance. You know that trick where opera singers can shatter a wine glass? They do that by singing at the glass's resonant frequency, causing it to vibrate until it shatters. The same principle ...
This is roughly the same as Bald Bear's (first) answer, but more fleshed out... The "ruins" are built (and removed) by "cloaked" repair mechs of unknown origin. These mechs have some form of proba...
First, the object hits: The Atmosphere. Earth's gasses and most other like-fluids as we know them would exert pressure and friction on any incoming objects, the objects would heat-up on the surfa...
There is absolutely no way to resuscitate someone who has been dead for long without basically magic-level-tech. When a cell dies all the metabolic functions cease. They stop ion transport which a...
[Would a dichromat] necessarily not be able to detect large light wavelengths (red)? I would much rather them not being able to detect small (blue) instead, and have a similar vision to tritanop...
This is a little outlandish (and, for the record, no I am not actually a pastafarian), but might give you ideas regardless... What is this "gravity" you speak of? Everyone knows there is no such ...
"It's the smell!" -- Smith I think the easiest answer is that there is something in Earth's biology that disagrees with them... something that can be "managed" with continuous medical interventio...
I can think of a couple options: Gray Goo An unstoppable swarm of nanites, or maybe even larger (e.g. insect-sized) creatures that destroy all non-bio-associated metal, would probably do the tric...
Handwaving away some of the problems here, one basic one appears insurmountable: Decoherence. This is a process that involves the destruction of the superposition of a quantum system. The loss of q...
Theoretically you could do this using magnetic stimulation of neurons. The magnetic field induces an electrical potential in the neuron which actives the neurons and it can work from (small) distan...
I imagine your character would become incredibly frustrated, if not go insane outright. I would try to imagine how you would feel if you were unable to speak and had your hands tied behind your bac...
