There is only a handful of science-fiction movies that in fact show what moving about inside a spaceship would truly be like. In most flicks, they use a type of "artificial gravity" that is never fully explained. Now, a new paper established for publication in Physical Review D strength turn that science-fiction idea into a truth. Professor André Füzfa, from the Universitede Namur in Belgium, thinks we have the skill to create and influence weak artificial gravitational fields. The claim is bold but grounded. Füzfa has calculated that by using very strong magnets, it’s likely to create tiny distortions in the space-time.
The theoretical starting point of Füzfa's investigate is theequivalence principle. The principle state that the force experienced by an observer in a gravitational field (like you on Earth) is equivalent to the force experienced by another observer in a non-inertial field (an astronaut in an accelerated spacecraft). In simple terms, if you were in a room with no windows, you would not be able to say if you were in a gravitational field or the room was accelerating in the way of the ceiling.
The equivalence principle tells us that each mass and every type of energy are affected by and generate gravity, so it should be likely to create gravitational fields with intense magnetic fields. Thus, Füzfa performed full calculations solving Einstein’s universal relativity equation around a powerful looping electromagnet, and the resolution indicates that the effect is small but significant. More importantly, he suggests that an experimental set-up could be carried out with present technologies.
Although the envisioned experiment is potential, it would require a significant investment. The magnetic fields require to be generated over a lot of days using layers upon layers ofsuperconductive magnets, as well as sophisticated and sensitive laser system that can detect the small variation in gravity within the -magnets.
The paper will definitely challenge citizens into taking another look at the relationship flanked by electromagnetism and gravity. And while we might not be earlier to the gravity machine, we might be getting earlier to at least understanding -gravity.
