In general, with the small number of negative health effects present in today's typically shorter spaceflights, as well as with the very large cost of research for a technology which is not yet really needed, the present day development of artificial gravity technology has necessarily been stunted and sporadic.

For example, an AU fan fiction might imagine what would have taken place if the plot events of the source material had unfolded differently, or it might transpose the characters from the original work into a different setting to explore their lives and relationships in a different narrative context. Unlike typical fan fiction, which generally ...
Spacecraft in Joe Haldeman's 1974 novel The Forever War make extensive use of constant acceleration; they require elaborate safety equipment to keep their occupants alive at high acceleration (up to 25 g), and accelerate at 1 g even when "at rest" to provide humans with a comfortable level of gravity. In the Known Space universe, constructed by ...
TAU concept art Stellar parallax is the basis for the parsec, which is the distance from the Sun to an astronomical object that has a parallax angle of one arcsecond. (1 AU and 1 pc are not to scale, 1 pc = ~206265 AU) What TAU would do is use its distance from the Earth to make the parallax measurement, so rather than just 1 AU as with an Earth-based annual parallax it would be hundreds of AU.
Improving measurements were continually checked and cross-checked by means of improved understanding of the laws of celestial mechanics, which govern the motions of objects in space. The expected positions and distances of objects at an established time are calculated (in au) from these laws, and assembled into a collection of data called an ...
A space suit helmet featured in the film. Kubrick consulted aerospace specialists to ensure the design's accuracy. The general approach to how space travel is engineered is highly accurate; in particular, the design of the ships was based on actual engineering considerations rather than attempts to look aesthetically "futuristic".

From the 16th until the late 19th century, gravitational effects had also been modeled using an aether. In a note at the end of his work "A Dynamical Theory of the Electromagnetic Field", Maxwell discussed a model for gravity based on a medium similar to the one he used for the electromagnetic field.
In 2006, it was proposed that the application of loop quantum gravity techniques to Big Bang cosmology can lead to a bounce that need not be cyclic. [20] In 2010, Roger Penrose advanced a general relativity-based theory which he called the "conformal cyclic cosmology". The theory explains that the universe will expand until all matter decays ...
