Manipulating time and space

real_aurgathor

Does anyone know how can humans manipulate time and space since I’ve seen a claim that: “Our technologies permit us to manipulate time and space.”

Maybe poke around on PBS Space Time on Youtube

Humans? No, Time Lords Yes:

Doctor Who is a British science fiction television series broadcast by the BBC since 1963. The series, created by Sydney Newman, C. E. Webber and Donald Wilson, depicts the adventures of an extraterrestrial being called the Doctor, part of a humanoid species called Time Lords. The Doctor travels in the universe and in time using a time travelling spaceship called the TARDIS, which externally appears as a British police box.

All massive objects (and I include all things with energy as well) “manipulate” time and space. In the words of the great John Archibald Wheeler, “Mass tells space how to curve, and space tells mass how to move.”

Coincidently, just saw this article.

New theory suggests gravity is not a fundamental force
A fresh look at gravity challenges long-held assumptions about one of nature’s most familiar yet puzzling forces. In a new study, two researchers argue that gravitational attraction is not a basic force at all, but an effect that emerges from deeper quantum processes tied to electromagnetism. If confirmed, the theory could help explain mysteries that have long resisted standard models — including the origins of dark matter and the energy accelerating the universe’s expansion.

real_aurgathor Does anyone know how can humans manipulate time and space

Humans manipulate my time and space everyday. 🙄

Sparkchaser Interesting, I shall have to familiarize myself with the relativistic transactional interpretation of quantum mechanics before reading the original paper. There are many current attempts to unify gravity and quantum mechanics, some promising, others not so much.

Sounds like this is a job for ~~Superman~~ Einstein.

Among other things:

Special relativity is a theory of the structure of spacetime. It was introduced in Einstein’s 1905 paper “On the Electrodynamics of Moving Bodies” (for the contributions of many other physicists and mathematicians, see History of special relativity). Special relativity is based on two postulates which are contradictory in classical mechanics:

The laws of physics are the same for all observers in any inertial frame of reference relative to one another (principle of relativity).

The speed of light in vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source.

The resultant theory copes with experiment better than classical mechanics. For instance, postulate 2 explains the results of the Michelson–Morley experiment. Moreover, the theory has many surprising and counterintuitive consequences. Some of these are:
• Relativity of simultaneity: Two events, simultaneous for one observer, may not be simultaneous for another observer if the observers are in relative motion.
• Time dilation: Moving clocks are measured to tick more slowly than an observer's "stationary" clock.
• Length contraction: Objects are measured to be shortened in the direction that they are moving with respect to the observer.

Somewhat-Reticent

And what’s changing - tick time / object height, or measurement thereof …

Walter Isaacson’s biography of Einstein is a good read for those interested in the development of special and general relativity.

Ohio State University has a great paper on the application of general relativity in the GPS system. Despite the GPS satellites traveling in orbit relative to the earth, earthbound clocks run slower relative to the orbiting clocks. The effect of gravity is greater than the effect of relative motion.

I must find the paper again, will post link if I do.

I dunno about time, but Moholy-Nagy was pretty well known for his light/space modulator.

Perhaps a precursor to the Illudium Q-36 Explosive Space Modulator.
