Could a high powered telescope in space (such as the Hubble Telescope) be capable of peering through a large worm hole with enough clarity to detect that a planet is somewhere on the other side? I...
For the purposes of this question, "teleportation" refers to Star Trek style teleportation: a body is diassembled in one location, and reassembled with an exact (perfect) replica of the entire cons...
Suppose it was possible to travel to inside the event horizon of a black hole safely. Also suppose said black hole is large enough that the curvature of the horizon of the surface of the central ma...
For a species I am working on, there is a specific genetic trait that I want to introduce into the population. The exact nature of either is not important for the purposes of this question, but the...
What kind of a scenario would have to occur in order for human beings to seek survival on the sea floor? It could be man made or natural, ice age or heat apocalypse, sudden disaster or gradual coll...
We know that planets can have multiple moons, sometimes quite a few (like Jupiter). Assuming that a planet with several moons were habitable in the first place and has significant oceans (greater ...
If a planet always faces the same side to the sun, so that it has a permanent night side and a permanent day side, it will have a twilight zone in between the two sides. This will be a band around ...
This question is a bit of an outgrowth of Can you simply scale up animals?, but it does approach it from a different angle. "All else equal" (which it of course never is, but we're good at pretend...
How would the human body be affected if the oxygen levels on Earth suddenly decreased by 15 percent? This is instant. Not over time. How would we adapt? Would some people die and some not?
We have already discussed how difficult it would be to blow up a planet like Earth, basically deciding that you can't do that with any reasonable amounts of energy. But what if I don't need to blow...
The setup: Near future (maximum 50 years in future) where "only" thing changed is, that company SpaceX together with NASA and ESA found out, how to get cargo and people to space very cheap USA dec...
I have a roughly Earth-like planet in a solar system some distance from ours. The atmosphere of this planet is largely similar to that of Earth, but particularly, has a somewhat higher oxygen conte...
In the wake of this, my answer to this question about where to put a Dyson Sphere an apparent issue came up. And it needs some good resolution: What are we going to do with all that heat the syste...
While this is a hypothetical question, I am actually looking for a 'real-world' answer. This is my first time here, so please let me know if I should ask it somewhere else. So, let's say I am an o...
I'm designing an FTL system for a new universe, and I'm trying to figure how 'plausible-sounding' this thought is. The idea is that space is tangled and twisted in twelve dimensions, so that dista...
I've noticed that some questions have a mismatch between the number of answers showing in the question list page, and the number of answers showing on the specific question page. For example, the R...
I'd recommend a Kalman filter to increase measurement accuracy to the overlap of multiple system errors so that you get the best result. For inputs, may I recommend - a calculation of doppler s...
Look around the world to see what is possible with our current technology. The Golden Gate bridge has a deck 90 feet wide (27 meters) supporting 6 lanes, and its main span is 4200 feet (1.28 km) l...
The way I see it for now (and I reserve the right to change my mind in response to discussion in response to this :-)) All of these points are valid for both questions and answers in the standard ...
Question requirements I think it definitely falls on the asker to demonstrate first and foremost that the basic tenets of their idea are feasible. Their question should show that they've done a go...
Whatever means you use, it would make sense to have two measurements: Time To Destination (TTD) relative to yourself, and TTD relative to the destination. E.g one year for you, two years for the pe...
No, the scheme described doesn't make sense, regardless if it is digital or analog. Anybody can intercept the public key and decrypt so the scheme doesn't protect against eavesdroppers. The entiti...
Tornados and the thunderstorms that often spawn them are driven by rising columns of air. Such "thermals" are stronger and more likely in open terrain, like is prevalent in Tornado Alley. Let the...
You have mass flow rate and velocity, but the area this is spread over will say a lot - $$\dot{m} v = F = 1 {{kg} \over {s}} \cdot 1,000 {{km} \over {s}} \cdot 1,000 {{m}\over{km}}= 1 \times 10^{6...
Previous Concepts I did a quick literature review for this on google scholar, and unfortunately it seems like there isn't much research on the topic. I did however find this short article, which h...
