If you're studying radio signals from Earth, is it possible to calculate whether a radio source is 'near' as in near Earth or 'very far away' as in somewhere far out in space from velocity, or velo...
I've had a number of interesting conversations with people about how the cosmic microwave background (CMB) will evolve in the future. The CMB is the sea of photons left over from the epoch of recom...
Imagine one day the moon suddenly transformed into a colossal elephant's foot and we need to get to the moon to obtain sample... Could it be done using modern day technology to mine the uranium for...
Imagine a light spaceship capable of traveling at 0.999c is tasked to tow a radioactive cargo containing millions of tons of polonium and radium, however the container holding the radioactive mater...
I know we generally operate - or religiously operate - on the principle that fundamental things don't change over time. It's the bedrock of geology - Uniformitarianism. I also believe it is unprova...
This question is meant as a reality check on this answer to The land grows evil and corrupted ... but why? Radioactive moon in a nearly geosynchronous orbit. It slowly kills or alters all li...
A bit outlandish, but here me out: I'm trying to make a villain for my story who's essentially like DC's Fallout in powers. Attribution: January 2015, dc.fandom.com/wiki/Fallout That being said...
Far away, across the vastness of space, lies an alien civilization, who are pretty similar to us. They've got ice cream, peer to peer networking, and photography. More importantly, they do lots of ...
I am working on a world which is very dark due to an opaque gas layer in the hight atmosphere; but it is opaque mostly in the terahertz range. The creatures in this world therefore rely very little...
Premise: Neurologists found that GHz wireless RF had modest but quite negative effects on people's brains. Subtle collective effects in neuronal firing patterns across the brain due to interactions...
I am looking for a good reason to make radio communications on a planetary scale unfeasible or impossible. Short-range use is acceptable, but no transmissions should make it to orbit or over the ho...
I'm making a hard-ish sci-fi universe where humans colonized nearby star systems and found not one but two civilizations in Alpha Centauri, each at home on a planet orbiting one of the two main sta...
Is it was technically possible for a superhero that senses radio waves (like low frequency EM) to "hear" the radio? This superhero senses radio waves a bit like we can see visible light, though n...
In relation to a recent question of mine, this alternate Earth still has its core consisting of 84% iron, but the other 16% contains the greatest concentrations of all known species of heavy metals...
Could animal produce less than 700MHz radio waves to communicate ? I don't want those waves interfere with mobile phones and other intercontinental radio communication my space colonists would use....
So, in this world, the future's wars are fought by drones and recruit teenagers with attitude, who control and repair drones in a temporary base near the front, and are frequently targets of surpri...
The only such media I've seen is Fallout, which is obviously highly fantastical. I mean, they mutant animals and irradiated zombies running around! But realistically, is there anyway that life cou...
In the story of my video game, I want a group of colonists to land at dawn on an alien planet and have to terraform or build protective structures before sundown (several earth days). I want the d...
The exposition is that a civilization exists about 200 light years from earth and has been capable of radio communication for several thousands of years. They are not trying to hide from detection ...
One of the worlds I'm creating has a planet-wide communal sentient Biosphere (similar to Avatar). They have evolved the ability to bio-engineer whatever they need, and they have decided to send a p...
I recently came across Could pulsars really act as "lighthouses" to help in interstellar travel?, asked a week ago. The author was trying to figure out if pulsars could be useful for interstellar F...
Imagine there are two regions, one of which has a significantly higher level of radiation. Think of Pripyat (higher level of radiation) and its surroundings (lower levels). How can a person withou...
A gram of vaporized polonium can kill more than a million people and thus is the most potent poison known to Man. Having read this article, my crazy dictator immediately assembled the most experien...
What materials would be significantly better than currently commonly used radioactive materials (Uranium/Plutonium) for energy generation? I am looking for some material which could've been brough...
Given modern technology, what kind of bandwidth could you expect for communication with an extrasolar spaceship? For example, is HD video possible? Is it safe to assume it would vary by distance? O...
I'm looking for creative people with knowledge of radio waves and space flight to help me out. I'm currently writing a screenplay about a spacecraft that is basically a radio antenna in space. The...
The year is 2109 C.E my friends and I were caught in a space disaster when the spacecraft we're in broke apart during a daring escape from a patrolling spacecraft. We stole an antique cellphone (fr...
Setting: Western world nation, Earth as we know it, May 2016, Gregorian calendar. Eccentric billionaire, large multinational corporation or similar; lots of money, and ability to enlist the help of...
I make no assumptions to the nature of this planet. There are high chances it does not have an atmosphere or a lithosphere. But in a planet that shows a high level of radioactive activity, would it...
I was thinking of a situation in which a creature lives in a region in which the levels of radioactivity varies from harmless to lethal from place to place and time to time. It takes millions of y...
Radio Thinkers Creatures that communicate by biological radio pops up in science fiction occasionally and it's a fun idea. However, there are some practical concerns with regards to evolving a ra...
The US Government, and eventually the UN and all nation-states around the world, have realized they are broadcasting their existence to potential enemy civilizations in the nearby galaxy (at least ...
