Perhaps a vast colony of lithotrophic organisms lives deep beneath the sand? Long ago, the region was a rocky plain. Then, a species of lithotrophs was introduced, and they began to consume the ve...
Allow bloodline proxies Adoption is the obvious choice for most male and many female couples. But if bloodline is important in a particular family, allow for a proxy. For example, if a female co...
The Gods determined that taboos must be broken. Just as in Greek mythology, the Sphinx - Σφίγξ- was most often depicted as female with a human head, a lion (or other great cat) and wings: ...
Aethir. Known to the ancients of Greece, Aether (after a god of the same name): pure upper air that the gods breathe... According to Epiphanius, the world began as a cosmic egg, encircled...
TL;DR As most of the other answers say, the plants on this world would likely be purple-ish, using photosynthetic pigments that operate at the same wavelengths as bacteriochlorophylls. Chlorophyll...
I'm going to address the pricing model. The hourly rate workers get in India is much lower than minimum wage in the United States. But it varies a lot depending on skillset. Here you need worker...
You will likely have an easier time if you pick a Slavic language that uses a Roman alphabet. Like Czech or Slovak (which are very similar to each other). Then you don't have to deal with the unkno...
A Collision at relativistic speeds with a PBH. A primordial black hole, according to Russian Physicists: Yakov Borisovich Zel'dovich and Igor Dmitriyevich Novikov in 1966 first proposed the ...
One approach is to look at shoes used by people with upper-limb amputations or who were born with missing upper limbs. While your characters are not human and may or may not have partial or full u...
The impractical part is that you would need to grow an entire human being (or all the pieces of one in a single unit) just to get one organ. A patient in need of an organ would either be put in...
Some yes, some no. There are alternative pathways laid out below: If you're going to grow a clone for replacement parts, you need stem cells. These can be found in one of a few ways: Day 2 or ...
Edited. - as per edit to the question. Assuming the Current model of the universe. Fore: nothing, because - Photons blue-shifted beyond the furthest reaches of the EM spectrum (way beyond human p...
Rule of law and transparency. (What's in a name.....) All magic-users have magical-names (one each), either given them by others or chosen by themselves (more accurately, they need to find out wha...
Your environment is quite similar to that in a globular cluster. At its densest, a globular cluster may see peak stellar number densities of $\sim1000$ stars per cubic parsec, which implies a mean ...
The short version is that it depends entirely on the manner in which the moon disintegrates, or more specifically the energy thus imparted on the resultant fragments. I'm assuming here that the ma...
TL;DR I'd propose that weak force life has a tiny change of existing in environments where particles travel at high speeds. A possible example is the jets produced by an active galactic nucleus. A...
This is an addition to Willk's answer; Giant pupils would be a very good start, with the addition that the iris would have to be able to get the pupil small enough to allow function in the dayligh...
Like M-Blocks. In this clip you will see them performing extraordinary maneuvers twisting, jumping and walking. This part 45 seconds in shows them interacting nicely with each-other. They use mag...
FOOD As others have mentioned, food isn't an issue. You have fish and you have seaweed. You can farm fish and also do things like grow oysters on strings. Some vertical farms on the boats could...
No, it's not possible. A true allergy is mediated by histamine (released by the mast cells) and involves an "immune system-mediated adverse reaction to food proteins." (Or to non-food proteins in...
No. Tidal locking near a black-hole (which you'd need for your effect to remain in one place on your planet) is impossible because of: Magneto-rotational instability Black holes exist in an extr...
No. The mass extinction you're hoping for"”no plants and only microscopic animals"”is impossible from these conditions. At the point that humans left the planet, it was possible for animal and pl...
It's a retrovirus A retrovirus is a type of RNA virus that inserts a copy of its genome into the DNA of a host cell that it invades, thus changing the genome of that cell. Such viruses are ...
You'll want to start with technology that produces light suitable for growing crops indoors. Grow lights exist of course but they're awfully energy intensive. With near-future technology you'll h...
It is not practical, you would need to launch the bullet/projectile with enough fuel to: Stop its forward movement Start movement in reverse Slow down and stop when it got back. At each step ...
