Light traveling from distant stars takes years to reach Earth. By the time it reaches us, that light is carrying information from the past. A different hypothetical faster-than-light particle, the tachyon, carries information from the future, proposed Philip K. Dick  (see also short video of PKD hopefully embedded above).
A tachyon or tachyonic particle is a hypothetical particle that always moves faster than light. In special relativity, a faster-than-light particle would have space-like four-momentum, in contrast to ordinary particles that have time-like four-momentum.  (In special relativity, four-momentum is the generalization of the classical three-dimensional momentum to four-dimensional spacetime. Momentum is a vector in three dimensions; similarly four-momentum is a four-vector in spacetime. )
Something momentous happened to Philip K. Dick in 1974. Following a tooth extraction, P.K. Dick “watched as his whole universe collapsed and was replaced not by a new universe but by a series of hypothetical or virtual universes.” Gradually, Mr. Dick perceived his experience as “a revelation of the greatest false memory case in history, imposed on all humanity… most of the last 2,000 years of history never happened. We have been brainwashed by the Roman Empire to think we are living in a totally false world.” 
It is commonly believed that a drowning person experiences a moment when, in an instant, his entire life flashes before his eyes. This suggests a situation where “time” somehow has ceased operating. P.K. Dick may have experienced something similar when “his whole universe collapsed” in 1974. Thereafter he worked ceaselessly to try to make sense of his experience. His efforts – thousands of pages of typed and handwritten notes, journal entries, letters, and story sketches – were posthumously edited and collected in the book, The Exegesis of Philip K. Dick. (Further background: Isaiah and the Praying Mantis, Ersjdamoo’s Blog, December 8, 2014.)
The enormous output of P.K. Dick is still being sifted through by a team of volunteers working via the Zebrapedia web site. Much has yet to be published.
Prior to his 1974 epiphany, P.K. Dick had had more of a mundane idea of “time.” The idea of “time” as a force had not occurred to the popular science-fiction author. The idea that “time” could weaken or even disappear had not yet been considered. One source which helped P.K. Dick deal with his post-epiphany effort to understand was a Russian scientist, Nikolai Alexandrovich Kozyrev.
In 1931, Nikolai Alexandrovich Kozyrev was considered to be one of the most promising astrophysicists in Russia. But then he got on the wrong side of Josef Stalin and was arrested in November 1936 and sentenced to 10 years for counterrevolutionary activity. As a result of Kozyrev’s imprisonment he was mentioned in The Gulag Archipelago by Alexander Solzhenitsyn. 
Spiraling energy patterns in nature unveiled themselves to the initiated eyes of Dr. Kozyrev while in the concentration camp. This spiraling energy was in fact the true nature and manifestation of “time”, Kozyrev eventually concluded. “Time” is ultimately nothing but pure spiraling movement. Without movement there can be no “time”. The common scientific terms “torsion fields” and/or “torsion waves” are used nowadays to describe the spiraling flow of “time energy” that Kozyrev discovered. Lt. Col. Tom Bearden calls them “scalar waves”, however perhaps “torsion waves” is ultimately an easier term to use, since it continually reminds us of their spiraling nature. What we are dealing with is simply an impulse of momentum that travels through the medium of the aether/Zero Point Energy/physical vacuum, and does not possess electromagnetic qualities. 
The “torsion field” is a “spin field”, a whirling vortex. Dr. Kozyrev had first noticed the spiraling energy patterns in nature while he was imprisoned in one of Stalin’s forced labor camps, and Kozyrev had connected the “torsion field” with “time.” Some of the latest thinking on The Ether is of a “hyperdimensional model” of the universe which posits The Ether as the actual transformation medium between the higher spatial realities and our (3-D) dimension – through the “torsion field.” (Higher spatial realities would be, in other words, the fourth dimension and beyond.) Unusual geometric figures are associated with the torsion fields, for example the Seal of Solomon in three dimensions. (Background: Our Friend, The Ether (Part 23), Ersjdamoo’s Blog, November 20, 2013.)
“Time” was in fact a force, or at least so it appeared. And “time” in our own actual universe could weaken, or even go entirely away, realized Philip K. Dick. Back in 1974, when “his whole universe collapsed”, P.K. Dick “saw the universe as it is, I saw as the active agent, a gold and red illuminated-letter like plasmatic entity from the future, arranging bits and pieces here: arranging what time drove forward.”  That vision of the “gold and red illuminated-letter like plasmatic entity from the future” may have been carried to P.K. Dick by tachyons. If the tachyons carry information from the future into our present, this might explain how P.K. Dick had seen that particular vision.
