QM: Does Time exist?

At the close of the 19th century, the notion of an ether was posited. However, following certain scientific measurements purportedly conducted in the United States, this concept was ultimately discarded, a stance that Nikola Tesla never relinquished. He maintained the belief that the cosmos is permeated by ether, regarded as an ideal fluid—a substance that is not materially tangible but solely conveys energy and possesses an extraordinarily vast amount of energy. If we were to calculate this energy on the basis of Einstein's theory E=mc², which is really correct, the entire matter of the cosmos, we would get enormous values that our brain cannot comprehend. This is so much energy that our civilisation could use it indefinitely, as long as it exists. Tesla demonstrated this energy through his resonator.
In 1892, Nikola Tesla constructed a resonator through which he passed electric current, alternating, of the same intensity but in the opposite direction. He was given self-cancelling electromagnetic fields. And the great energy that was invested in that process turned into a completely new type of energy. It actually produced a completely new type of electromagnetic wave.
Tesla produced in the laboratory electromagnetic longitudinal waves that vibrate in the direction of propagation and that do not lose their power no matter how long or how far they are transmitted. Since these are scalar waves, Tesla stated that with that resonator he in fact provided the time-space energy characteristic of the resonator, so the wave went from the existing four-dimensional space to the fifth dimension. And that's why that wave carries enormous energy. Longitudinal wave energy constantly exists in the ether. Tesla called these waves spiral because they leave a spiral trail.
Regrettably, in the U.S., the notion of free energy was rather rudely dismissed. Back in 1901, our dear friend Tesla proclaimed the tantalising possibility of harnessing infinite energy, declaring, "Humanity must get its act together and tap into the flywheel of nature to achieve a swift leap forward in civilisation, whereupon the energy conundrum will be neatly sorted." Had Tesla's vision been brought to fruition, one might imagine a world where everyone lived in comfort and where, dare I say it, huge masses of people enjoyed a rather plush existence. It was a truly astonishing scientific discovery. In addition to being inexhaustible and free, it was absolutely clean energy and meant to put an end to the pollution of nature.
Indeed, Tesla's generator was quite the revelation, particularly for those in the fossil fuel business. When Tesla presented his patents to Morgan, the response was rather curt: "Goodbye, Mr. Tesla." Not long after, the generator met an untimely end, followed by the demolition of Tesla’s grand tower and a rather unfortunate fire at his laboratory. His project promised to be a beacon of hope for humanity, yet the big corporations were less than impressed; they saw not salvation but a threat to their profits. Thus, it’s not some fanciful conspiracy theory—this is simply a matter of historical record.
