Drastically. For one thing, pinning your opponent's shoulder to the mat is no longer possible. Very different criteria would be required to determine winning. The different objectives would in t...
You would send out a small laser or radar retroreflector out of the side of your ship and observe the tracking angle. Knowing the speed of your marker you can calculate the speed of your ship with...
Before launching the site, we had a discussion on Codidact Meta about naming the category we currently called "Researched Q&A". Other possibilities we explored included "Hard science", our sta...
A back of the envelope calculation suggests that you need a velocity relative to the CMBR of more than 0.9c. (1mm microwaves blue-shifted to 570nm light typical of yellow dwarves) This is a proble...
What I need is a substance which could have been mixed by an alchemist and is as gold-like as possible. How about gold itself? Bear with me, here: While there are a lot of things that look ki...
This question really has no answer because it is phrased in a way which doesn't actually have much meaning. As phrased, it appears as though the universe is governed by these constants, which can ...
Yes and No. Yes: Therefore, strong enough magnetic fields have the ability to deform and even break objects. When a magnetic field gets stronger than about 500,000 Gauss, objects get ripped to pie...
A classic image of mermaids are their long flowing hair that swishes in the water. But in the scientifically realistic sense this makes none. The hair would be nothing more than a nuisance to the m...
What would be the best way in which to genetically modify (or create through some other method) an animal which breeds normally for a certain number (50?) of generations before becoming sterile? Ge...
I want a world in which animals roam the wilderness on four legs, yet at least some of them are able to do the kind of carrying and fine handling of objects done by humans. The planet is superficia...
Nature does this on its own, given enough time. Different tree species have evolved different strategies. Some require a lot of sun, grow fast, and make a lot of seeds before being overshadowed b...
The Earth would be broken into pieces if the total energy delivered by the impacts was comparable to the gravitational binding energy of the planet. Earth is a sphere, so its binding energy is $$U=...
I don't think it is feasible for an elephant-sized hyena to hide on the actual hunting grounds, least of all from predators that have similar excellent senses. What it should do is to lay low some ...
Get ready to wave those hands How active do these giants need to be? I ask because Wikipedia's list of tallest people notes a lot of health problems. The 25 tallest people who are no longer living...
Gravity You seem to assume that the Moon's mass is mostly concentrated in its core. While I didn't find detailed data on the Moon's density distribution, this Wikipedia page tells that the density...
Something you may not have thought of: the Earth-Luna system has the barycenter inside the Earth's radius. Fairly deep inside, in fact -- about 25% of the way down from the surface. Your system as...
To replace using the like of the 'hard-science' tag on Worldbuilding SE, we have the 'Rigorous Science' category. As evident in the name, this involves 'research' of some form, but what does this m...
It looks like something went wrong during the import, causing imported posts to get the wrong character encoding. I fixed one at https://speculative-science.codidact.com/q/225476, but have come ac...
The Strawberry Jam can freeze parts in place that don't heat up much. Parts of the trigger mechanism would be a good candidate. So is making the lock stuck in safety mode. Also, you don't have a...
It looks like you will have uplift, frequent earthquakes, and volcanos in the lower part of your island where three plates are jamming together. In the northern part, the plates are spreading. Yo...
This is not a bug, it is a feature The gun isn't hot until you fire it. That first shot will, due to the trauma, cause the jam to solidify and block the bullet. At the same time, the heat will dea...
I would think that, at the very least, [science-based] is implied by this site's scope and doesn't add anything. (I didn't think to ask for it to be stripped on import, but presumably it's not har...
Codidact's communities have a lot of great content that is helping people on the Internet. Our communities are small, though, and sustainable communities depend on having lots of active, engaged p...
I feel like science fiction doesn't have many sports, other than the occasional laser battle or fantasy sword duel. I'd like to start a discussion series about sports in a low-gravity/no-gravity e...
The Honey Badger is known to kill water buffalo by ripping out their scrotum and letting them bleed out. Mostly out of spite I think for being disturbed, they mostly eat small game, honey, bee lar...
