Question How to survive the G-force of Space Travel
In my world ... Actually, in every hard sci-fi world with casual interplanetary travel, the G-force involved in acceleration would becomes so high that no unmodified human being could realistically survive it, leading to an authorial work around of some sort, or it simply not being addressed in the w...

Question How does a solar sail return to its world?
While trying to figure out a way that individuals could own spacecraft in my sci-fi setting without having access to things that could double as weapons of mass destruction, I settled on the widespread adoption of civilian solar sails, or more specifically, photon-particle sails. It has quite a few ...

Question Why would Fission be used in a world where Fusion reactors exist?
In my world, all terrestrial bodies in the solar-system of over 900 km size have a significant human presence. Earth-moon Travel is as common as an interstate road trip, and Interplanetary travel is as common as going overseas, ranging from Venus to Earth is the same as a trip from the U.S. to U.K. t...

Question What practical issues might prevent making a conventional-explosives bomb-powered spacecraft?
Project Orion was a project to construct a spacecraft that rode the shockwaves of nuclear blasts as a form of propulsion, but the project was abandoned because of budget cuts, environmental concerns, and the end of the space race. In my world, a new space race starts between the U.S. and China over ...

Question Would super-sized humans be super-intelligent?
A mad, egomaniac, scientist has developed a way of extending the natural growth of humans to create an army of 20ft (6 meter) tall soldiers. Physiologically, they are three times the size of normal people in terms of height and mass. He's managed (through genetic enhancements) to increase the effic...

Question Is it conceivable, or at the least verisimilar, for Plutonium radioisotope generators/atomic batteries to power a small manufacturing town?
A small manufacturing town serves as a comparison. The worldbuilding significance is for an underground facility with, in addition to a medical center, small-scale chemical production, a machinist workshop, hydroponics, and cultured meat lab wherein living conditions are adjusted to minimize power co...

Question To what extent is maturation of the adolescent brain a matter of time versus experience?
I'm aware the brain--especially the portion concerning planning and judgement--isn't matured until around the mid-20s and that the brain's structure is sensitive to environment. That said, let's assume a society with the knowledge of the adolescent brain being different from an adult brain educates a...

Question How can I use magic to make this change in human reproduction feasible without hurting genetic diversity?
There was a culture I read about that understood human biology to be very different from what we know today. This was a matrilineal culture which believed that men did not pass on their genes, but a piece of their spirit. The spirit was the life force of a human being which kept the body alive. It po...

Question How to communicate with an A.I. that doesn't believe it needs a language
A thought experiment occurred to me today that, say we have a synthetic superintelligence that does not wish to talk to people, not out of malice, but from an agonizing indifference toward humanity.
