On the one hand, this is realistic because human beings have a tendency for othering other races with beliefs and assumptions that don't hold up to any kind of scrutiny (see, for instance, the relatively common belief in pre-1850 US that black people literally couldn't feel pain). On the other hand, we're nowhere near AGI right now and it's already obvious to everyone with even limited experience that AI can be creative (nothing is more creative than a PRNG) and emotional (since emotions are the least complex and most mechanical part of human experience and thus are easy to simulate).

It was born out of the recognition that scientific discovery and the creation of plausible fictional scenarios are often two sides of the same coin. Each relies on an understanding of the way the world works, coupled with the imaginative ability to invent new or alternative explanations—and even other worlds. Authored by practicing scientists as well as writers of hard science fiction, these books explore and exploit the borderlands between accepted science and its fictional counterpart. Uncovering mutual influences, promoting fruitful interaction, narrating and analyzing fictional scenarios, together they serve as a reaction vessel for inspired new ideas in science, technology, and beyond. Whether fiction, fact, or forever undecidable: the Springer Series “Science and Fiction” intends to go where no one has gone before! Its largely non-technical books take several different approaches. Journey with their authors as they • Indulge in science speculation—describing intriguing, plausible yet unproven ideas; • Exploit science fiction for educational purposes and as a means of promoting critical thinking; • Explore the interplay of science and science fiction—throughout the history of the genre and looking ahead; • Delve into related topics including, but not limited to: science as a creative process, the limits of science, interplay of literature and knowledge; • Tell fictional short stories built around well-defined scientific ideas, with a supplement summarizing the science underlying the plot.

American Journal of Modern Physics . Vol. 4, No. 5, 2015, pp. 254-260. doi: 10.11648/j.ajmp.20150405.15 Abstract: A new concept, the gravitational propulsion, or "Hole Levitation", is proposed which propels vehicle by using the artificial gravity (vacuum holes). Such gravitational propulsion is similar to gravitational slingshot but without the need for large masses like planets and complicate maneuvers. The source of artificial gravitation accelerates the vehicle in one direction and the surrounding medium in the opposite direction. Therefore, it is not a reactionless drive: momentum is taken from the surrounding stars and planets and conferred on the vehicle and thus is conserved overall. The artificial gravity generator can damp or neutralize inertial forces due to the levitating vehicle is able to move with large acceleration, which is not acceptable for other means of transport.

The main limit to the use of gravity assist propulsion where no propellant is necessary but instead maneuver is that large masses like planets and moons are momentum of the vehicle is changed by an interaction of the seldom in the right place to enable trip to destination.

  • Mission Design and Trade Study Considerations for Reactionless Thrusters
    AIAA 2017-4843 AIAA Propulsion and Energy Forum 10-12 July 2017, Atlanta, GA 53rd AIAA/SAE/ASEE Joint Propulsion Conference Abstract for Mission Design and Trade Study Considerations for Reactionless Thrusters Dr. Shae E. Williams 1 Buffalo, NY 14203 Recent research on the subject of high-thrust reactionless drives have, to date, shown seemingly impossible amounts of thrust for a thruster with no exhaust. There has been significant attention to these claims, both in professional and media outlets, attempting to prove or disprove these reactionless thrusters. To date, nobody has performed a rigorous analysis of what missions these reactionless thrusters could perform in comparison to state of the art electric propulsion thrusters. This paper takes the results from the NASA-Eagleworks paper published in late 2016 of roughly 1 millinewton of thrust per kilowatt of power and shows that a reactionless thruster with these properties would only be superior to ion thrusters with mission durations significantly higher than a decade. To this end, a first-order estimation of the payload mass fraction of a spacecraft with conventional electric propulsion or a proposed reactionless drive is derived, and then applied to a range of mission scenarios with both current and near-term power generation systems and efficiencies. The major result is that a reactionless drive with this specific thrust requires very high specific power electricity generation, such as a 2nd generation in-space fission reactor, or is not competitive for most conceivable current and proposed missions. This paper does not take a position on whether or not the NASA-Eagleworks reactionless drive (or any other reactionless drive) is ‘real’, but treats the recent NASA-Eagleworks findings as though they were correct and applies them to top-level mission analysis.
