We often worry that humanity might be attacked by Aliens or AI, but which is worse and which would win in a battle between them?
Uplifting is the process of altering an animal - or even an alien - to be smarter or able to use technology. Our ability to do this seem inevitable, and with it a host of moral dilemmas.
A look at Statites, or Static Satellites, and variations like the Lagite, Quasite, Mag Sail, Solar Moth, and Non-Keplerian Orbits that offer us powerful foundations for advanced, Kardashev-scale space development.
Reaching new worlds is a difficult task, but transplanting ecosystem and civilizations to them may be even harder.
Our Final monthly livestream Q&A session recorded on New Year's Eve Sunday, December 31, 2023
Our future lies among the stars, and many challenges must be overcome to reach them. One of those challenges is making sure our ships don’t crash into our own garbage littering orbit.
We often discuss if space travel is feasible and if we can settle strange new worlds, but if we can, there is still the question of if we will.
In the grandeur of the universe, the tapestry of life may be woven from stranger threads than we ever dared to dream, and spun from materials far different to our own.
What does science tell us about reality and are there pathways to control, change, or re-create it?
Many doubt whether existence has any purpose or meaning, but could entirely civilizations become nihilistic. Would this spell their doom? And if not, what would they be like?

In the future we will travel to strange new worlds, but who will pilot the spaceships that take us there?
In science fiction we often see immense starships attacking planets, crushing or besieging them, but in our own future we may deploy powerful orbital fortresses to defend our world.
In the past, we had entire civilizations devoted to agriculture, but in the future, we might have entire planets devoted to it.
In order to survive and thrive in space, we have to be able to create and maintain clean and comfortable living spaces, and remain vigilant nothing disease or virus reaches Earth.
Among the billions and billions of planets and moons in this galaxy, we may encounter many examples of double planets, but what would they be like and could life arise on them?
Visions of a settled Mars always seem to have vast domes, but is a future on the Red Planet a domed one? And how should they be built?
As we search the heavens for signs of alien life, is it possible that the easiest place to find aliens is to look in the mirror?
In the grand theater of the cosmos, amidst a myriad of distant suns and ancient galaxies, the Fermi Paradox presents a haunting silence, where a cacophony of alien conversations should exist. Where is Everyone? Or are we alone?
Throughout history it has been common for distant colonies to break away from their homeland. In a future where colonies are entire planets and light years from home, shall history repeat itself?
Our penultimate monthly livestream Q&A session recorded on Sunday, October 29, 2023, at 4pm EST.
In some of our greatest wars on this world we have seen entire regions covered in fortifications, but in great wars across whole regions of our galaxy, could we see entire planets fortified?
As medical science improves and lifespans rise, we must consider not only if life extension is possible, but if it is ethical.
The industrial revolution saw the rise of factories so big they often grew entire towns or cities around them to operate, but in the future entire planets might be used to fuel the titanic projects for conquering the stars themselves.
Spacecraft may one day be so common that everyone has flown on one, with thousands of new spaceships being built every year in manufacturies dwarfing the enormous facilities we build planes and sea-going vessels in.
We often wonder where we might find a truly sustainable and abundant source of energy, and the answer might turn out to be in the emptiness all around us.
A collection of the first 20 Shorts from SFIA, covering a wide range of topics in science & space.
Space is often called the final frontier, a place of billions and billions of worlds awaiting explorers and pioneers. But what will those journeys be like, and what gear will people need for them, and perhaps most importantly of all,...
