One property of life is communication. In particular sound is very useful due to it's non-directional nature. An alarm call is heard by every member of the pack and warns them immediately of the da...
Let's say we're composing a message intended for radio transmission to intelligent alien life. We'd like to talk about sizes and distances, so we'll need a unit of length. We're already planning ...
Suppose that in our Solar System in the future will be two stealth ships (small cross section/low temperature signature/radar absorbent material). Still visible for human eye and detectable when mo...
Tech level is early Rome, China, Ethiopia, etc. ~ first century BC. Unlike history, there's peace and cooperation among all the benign monarchies of the whole Earth. But it's hard to get daily co...
Our war with the plants has been unending for thousands of years. And we don't even know it exists. Plants strategize, doing their best to survive, but the humans are relentless. Constant removal ...
Supposed we have a ship travelling at the speed of light, or very close to it, or over. A second ship is travelling behind it at the same speed. The second ship wishes to communicate something ...
Let's suppose we have found a new human colony today, somehow populating Pluto. They have good technology, much like ours and we don't want to slave them. We want to establish a communication link ...
Modern mechanical EM transmitters, like radio towers and radar guns, rely on finely tuned mechanical structures. If these structures do not have the right shapes, the device fails to function. Or...
Everything on Earth and in the Solar system is as we know it. However it is discovered that we live in a small but unbounded universe. That is to say if we travel far enough in a straight line we w...
Centuries ago, humanity have been incorporated into an alien hive mind, spread by a bacterial-like infection. The "bacteria" infects the blood and brain and allows the infected to join their minds ...
(Disclaimer: I tried this question earlier in the scifi site as well as real science sites, and was told should be on topic here) I'm writing a speculative story about aliens coming to earth - and...
I am super-rich person with a net worth of 32 billion US dollars. Part of my business is being contractor for NASA and SpaceX (so I have knowledge about space technology). I already own my island ...
Scenario: Earth men colonized a terraformed planet orbiting Alpha Centauri. There are already industries developed there, farms, mining etc. There's a large fleet of cargo ship capable of reaching...
So, let's assume you've cobbled together an interplanetary empire without using transportation methods that violate causality or have the power to blow up stars. You may feel pretty proud of yourse...
Given a world where a sentient species already populates, how would the population respond to another, unrelated species evolving into sentience? I think this can be effectively split into 3: It...
Something I realized not too long ago about a spacefaring society is that while a lot of technology is going to feel advanced, a lot more is going to feel ancient just because of all the hurdles it...
What ethical/legal implications would there be if we invented a technology to make it possible to communicate intelligibly with some (or all) animals? The constraints on this technology would mak...
