As I see it, the operative word in answering the question you're asking here is speculation. Now, of course, it's almost impossible to capture every nuance in a site name, which is why we have a pa...
You can't go by the shape of the building alone. No matter what the shape, presumably structural engineers carefully considered how the building will support itself. Buildings are not single mono...
When we did the initial import from Worldbuilding SE, the [hard-science] tag was handled specially and routed to the Researched Q&A category while removing that tag, but its siblings [science-b...
It seems you want to "store" energy as light by keeping it bouncing around inside a chamber. No, that's not going to work, at least not for more than a few 10s of nanoseconds for a chamber the siz...
While the other posts did already explain the issues with the cube-formed Earth, I just want to give a feeling of the dimensions we are speaking of. Imagine that the centre of the cube's faces are...
I would suggest simply closing them as off topic. Deleting the questions seems a little heavy-handed for now, but we should indicate to visitors (and people who might want to answer them) that a p...
Easy answer: No You're using the same technology to do two different things: remove hair and remove or encourage healing of scar tissue. Hair removal uses a laser frequency that's absorbed by...
You can hand-wave the right types of lights that produce the right mix of wavelengths, but you can't hand-wave away the power requirements. Sunlight reaching the earth's surface is about 1.2 kW/m2...
why would such a species have retained their ability to hear Because they still go outside to hunt, gather food and materials, and to interact with others of their species that live in other caves...
Yes, in my opinion. Other things being equal, the rate of heat loss from a human (or Neanderthal) depends on surface area. (You mention brain sizes but if that is in the expectation that a larger t...
This is based on a question in Writing about revitalising the community and is pretty much a blatant copy-paste of Monica's answer there. Essentially, it's been suggested that we remove all mass-i...
The first question is: What is instantaneous speed measured against (that is, what is the “ground” relative to which the speed is measured)? Remember that there is no such thing as absolute speed. ...
Your intuition is correct. Let's suppose that at STP, a human needs to breathe 1L of O2 in 200 minutes. That's 1.43g of gaseous oxygen. If the pressure is raised to 5 bar, a human still needs 1.43g...
First, the fussiness of the people has absolutely no bearing on how their solar system ended up. It is what it is, whether they like it or not. As for the physics, you are basically asking for ro...
Some topics may be good for a more general worldbuilding site, but are not appropriate for SpecSci. For example, How can my vampires hide in public? or How can I prevent the creation of fruit-sal...
A now-deleted question involved archaeology, linguistics, and history. There were some downvotes and critical comments, and the author deleted the question. I don't know whether the downvotes wer...
I received a notification saying that there's a new answer to my question: But when I clicked it, I saw no answers. I can think of 2 possibilities about what happened: There wasn't an answer and ...
It appears you want to go around a planet significantly faster than at the speed of a normal inertial orbit. That's gonna cost one way or another. Something has to create the downward force to ke...
Small islands have been built in inland waters since prehistoric times, but using sea floor material to build an offshore island is a much larger project. As Peter Taylor and JBH have pointed out,...
I speculate that because laser is heat and too much water especially with big/round laser beams can cause injected water to "boil" This argument doesn't make much sense. First, your insides are a...
Short, easy-to-read gene tags. Since all modifications are reliably policed, you can require that every modification includes a short, non-coding DNA sequence containing the recipient's legal iden...
a type of light we could perceive as black because our eyes ... do not That's anything in the EM spectrum other than visible light. So exclude roughly 400 to 750 nm wavelengths. Infrared and ultr...
If you lower the gravity, it is possible. Otherwise the wear&tear will cause a short lifespan (ligaments, joint cartilages, heart). Aside larger height, the bipedal position comes anatomic dis...
NASA's Fundamentals of Electric Propulsion: Ion and Hall Thrusters by Goebel and Katz, JPL, March 2008 discusses the issue of current ion drive beam focus limits (along with many other matters rele...
You are quite right. This has been fixed, thank you for pointing it out.
