Assuming an average, fully developed adult man, what sort of changes could be made to his genome that would have a noticeable effect on his mind or body? To the best of our current scientific knowl...
In many games the characters, particularly the main character, has weird physics. I want to know how these things could happen in real life and whether current technology could make it happen. Thi...
Imagine, if you will, a world where aural communication is impossible. Everything is done through gesture - sign language and written language are common, but the spoken word is not used, and using...
First contact with an alien life form often goes badly. In the case of Biothanata, it always goes badly. The first glimpse of this alien blob is in the form of a falling star, a meteorite. After bu...
I'm working on the setting for a fictional story I'm writing and I wanted to inquire as to how possible massive-Universe-sized planets are radius: 5.0x10^30M, without me having to re-make the laws ...
Though the job of breastfeeding is typically known to the women, there are documented cases of men producing breast milk. However, these reports are few and far between, which means that while men...
When the earth is flung out of the solar system as per Josh Pirhi's question, not everyone embarks on a spaceship. Instead, as earth becomes a rogue planet, a group of survivors created a self sust...
I'd like to remove the speed of light limit from my world. However I don't want to just hand-wave the consequences. How should my universe look if: light travels at infinite speed, and so do grav...
We've all heard about a river of blood. But what would happen if we had an actual river of blood? Say a band of vampires creates a magical portal that draws blood from all the people in the area ...
I've been reading the book Nomad, and in it a binary pair of black holes is cruising into the solar system, and threatens to slingshot the earth out into deep space That's got me thinking,...
Which solvent to use for metal nerves? Based on this answer on to how to evolve biological radios, the answer states that if creatures in an ecosystem utilize metal for electrical transmission ins...
Take the earth-moon system. Shift the moon's orbital plane about 90 degrees so that it is passes over both poles. What would the tides on this world look like? Sub-questions: What would the cy...
Listen. You hear that crunching, cracking noise? That's the marrow adders. They're all around us. Tiny, timid, pretty much harmless. If you break open one of the larger bones left behind by the bo...
So I thought up this alien parasite that enters through the mouth (usually of a predator) where it attaches to the throat and simultaneously takes control of the brain and replaces the esophagus of...
Everyone familiar with Godzilla should know of his iconic blue atomic breath. I've seen "theories" (technically not really theories) on how Godzilla's atomic breath works on the web. However, wha...
Would it be possible to have a planet made up of about 60-70% water with no landmasses larger than Australia? I would like this planet to be as earth like as possible, but I'm open to changing aspe...
There it is. The elusive Ersa 772. Filled with an estimated $15 trillion in precious metals, mining that asteroid could make you the richest man on this side of the galaxy. You have all of the fund...
You can imagine doing surgery on the brains of insects or spiders to implant electronic devices and transmitters so that it becomes a drone and will transmit data. To gain intelligence on a target ...
In the creature type I asked about in my last question, there are some lower caste members who seem to have metal limbs. However I don't think they would waste resources to build the legs for lower...
Let's say a 1600s civilization is around, making lots of iron objects: guns, swords, farm implements, etc. One day those people vanish. What conditions would allow their iron implements to be usa...
I have this idea of homicidal alien beings that upon death (after their body ceases living and begins to decompose) release enough poisonous gas into earth's atmosphere to wipe out all life on the ...
I'm continuing questions rooted in the same idea: a manned mission to a planet around 61 Virginis. The first set of related questions was asked here. We're sending a crew of twelve. They'll be i...
I've just read this article and watched the accompanying video. Heady stuff, for sure. I'm particularly intrigued by the concept of a "solar gravitational lens telescope" somewhere out near the h...
After writing this question about the ecology of a terraformed planet, I realized that I hadn't quite tied up all the loose ends of the terraforming process itself. I intended for a group of aliens...
Say you were using a black hole as a propulsion drive á la Crane and Westmoreland http://arxiv.org/pdf/0908.1803.pdf- so your black hole has a radius of around .9 attometers - super tiny - around ...
