Brown dwarfs are celestial bodies in the gray area between planet and star. They're huge, gaseous, hot compared to planets, and come in all different kinds. (1) Is it possible for life to develop...
Because of an error in the interpretation of the Mayan calendar I just discovered, I know now that Earth will be destroyed on March 13, 2021 at 11 o'clock in the morning, time zone of Palenque. I ...
What I want is to know if I could have seven Earth like (What I mean by this is having an Earth-like atmosphere and climate, in this scenario size doesn't matter and nor does gravity) planets in th...
WARNING THE FOLLOWING CONTAIN SPOILERS! I watched the first season of The 3% and I am wondering about the wisdom in the strategy adopted by this world. Spoilers Specifically, if the 3% ( "smar...
In a distant future, humans have colonized every corner of the solar system, and we can easily convert any object into anything else - be it food or a tricorder, you name it. Using these replicator...
Series Premise Made Short: For reasons that I'm not allowed to describe here (confidentiality), Earth's deciduous and tropical plant life largely dies off. A hardy and oxygen-hungry microbe infests...
Someone invents a portable, incredibly high-powered laser or similar energy weapon. The mechanism of energy production can be hand-waved away. In other words, it will heat up. Lots. Gigawatts lots,...
We are the only sentient civilization currently known to man, and sight is an integral part of both our everyday lives as well as most major technological advances throughout human history. Withou...
It is typical of fantasy stories that there will be a dragon somewhere down the line. They are typically the strongest boss right before or after the main antagonist. Now the question is what colo...
I can understand that all animals would instinctively stay away from a fire, however for a fire breathing dragon to be warded off by torches seem puzzling to me. What could help explain such ironic...
Let's imagine a near future where mankind starts to expand into the solar system. For various reasons, some humans start to be born and raised in space, in zero gravity and micro-gravity. What cha...
I'm trying to create a nation that is greedy, opportunistic & obsessed with profits and trade. They are cunning, treacherous schemers that will swindle you despite all the pleasantries and assu...
So, yesterday I found an invisibility cloak in my attic. It's got an instruction manual with it, and there it was mentioned that it is truly an invisibility cloak: it bends the light (actually, all...
Plenty of aliens from various galaxies have managed to land on Earth without getting tracked on Radars or satellites. For now, as I want my story to stay undisclosed, please assume that aliens have...
Let's talk about the visible light "rainbow" In almost all depictions of the electromagnetic spectrum, visible light is shown as a rainbow, and adjacent parts of the spectrum are monotone in color...
I'm trying to design a realistically looking capitol (with a few milion people) for one human nation on an exoplanet. The technology level is barely better than contemporary. The city is placed ...
I have the below snippet describing a planet in a (hard) sci-fi setting. This harsh planet has some human settlers, who can survive the climate in light weight environmental suits. The planet i...
A non-inertial frame, such as a planet that does not have constant velocity in its orbit, would change the laws of physics in many ways. For example, if you stood on the surface of the planet as i...
How can I make a colonizable planet/moon that receives intense UV/x-ray radiation on parts of its surface while receiving much less on the rest of it? The most obvious way of doing this is to have...
"It will be difficult enough to avoid disaster in the next hundred years, let alone the next thousand or million." "Our only chance of long-term survival is not to remain inward-looking on p...
In this scenario, all the humans on earth have disappeared, except for Fred. Sure, Fred is sad that everyone that exists is dead but him, including his friends and family, but he doesn't let that g...
Some of you have commented here: "How Do I Supplement Oxygen Intake?." I mentioned confidentiality, but that is no longer going to be a concern. We just want to do this right. The original concept...
A terrorist wants to shoot a bomb down onto an unsuspecting high-value target, for instance Washington DC. So, the terrorists somehow get a private space company to deploy what seems to be a norm...
I'd like a gravity room on my space vessel for long space stays to avoid osteoporosis. They would spend a few hours each day in this room, reading or doing paper work, to maintain bone-mass. I'm ...
Some more-than-usually clever boffins have knocked up a system that allows them to form portals into a region where the laws of physics are rather...different. An object that is fired through one ...
