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...
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...
Possibly, but I think it's unlikely, except indirectly. Exercise increases natural carnosine levels, so someone who both takes extra creatine and uses the energy to increase their exercise level p...
This is already done today The UAE artificial islands use material dredged from the sea bottom to ceate the islands. But is it sustainable? The easy answer is "no." You're not creating islands o...
The polar vortex nearly dies every year around springtime in the hemisphere you are concerned with. This failure is what brings those spring frosts in February, March. It's not really possible to ...
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...
This is general mechanics: all objects have a center of gravity. On a square-shaped house, this center is right in the middle, at coordinates (width/2, height/2). The wider the building is in relat...
The behavior of strange matter is not well understood - least of all under the conditions we're used to on Earth! Most theoretical treatments focus on places in which strange matter is likely to be...
The roadmap for getting people to accept machine takeover of almost any aspect of our lives is already here to be seen, for example in end-user licences (EULAs) on software people use (update softw...
If the merpeople's babies are relatively helpless or start as weak swimmers, head hair could remain as a useful point for the young to cling to as the adult swims around, keeping its arms free. Thi...
This already happened. I married my wife, who I met on an MMO, and I am far from being the only person this has happened to. Many, many people meet on the Internet and fall for each other online, w...
Update I've updated my CDF to handle eccentric orbits and customization of star brightness, and (more importantly) to show long-term seasonal effects. A few notes: Mousing over any of the par...
The known charge-conserving decay modes of free neutrons all involve the production of a proton, an electron and an electron antineutrino: $$n\to p^++e^-+\bar{\nu}_{e}$$ This beta decay is why, out...
Quantum Computers are considered a more powerful type of computer than so called 'classical' computers. While a typical classical computer could be considered as a black box that can solve Polynomi...
I'm spitballing a story where the main character goes through a monstrous transformation. Part of the conceit / my enjoyment is that she's an oncology researcher and will be tracking the transform...
Armies need more than just soldiers that fight. Herbivores can easily be more efficient at these other tasks because they don't carry the extra expense of the fighting apparatus (claws, sharp teet...
I'm a physicist, but an experimental one. This means I don't deal with hypothetical stuff like this very often, and when I do, I feel the need to figure out a real-world example or test for it. Als...
There's apparently a type of transmissible cancer that came from new world dogs thousands of years ago, the Canine transmissible venereal tumor. As I understand, this self replicating surviving ca...
It might be that between year 0 to the industrial revolution (say 18th to common era), the Caspian sea significantly larger than it is today. If so, is there some graphical illustration as part of...
I was recently introduced to the South Atlantic Anomaly. As I understand, for satellites and space craft, this is a natural feature that can wreck space craft by taking even computers designed fo...
So, Second Earth had/has a firearm problem. Since my magic is really just advanced science, I can't create firearm-disabling fields, so instead, I created a spell that should be able to ruin firear...
I've created a genetically modified race of humans with an extreme height. I've taken into account the cube square law, and added some bones and muscles to help cope with that. I'm planning on maki...
What will be the view of the sky and the distances between stars, living on a planet or in a habitat in a super galaxy that has merged with all its nearby galaxies in its cluster, at a time in the ...
