Time is not a dimension. "Spacetime has No Time Dimension" -- New Theory Claims that Time is Not the 4th Dimension. Einstein never interpreted time "t" as a fourth dimension of space. Space is not 3D + T, space is 4D. With clocks we measure numerical order of material change. This numerical order is the only time that exists in a physical world. With this approach all immediate information transfers of quantum physics are explained in a more appropriate way. 4D space is a medium of quantum information transfers. Scientists at the Scientific Research Centre Bistra in Ptuj, Slovenia, theorize that this Newtonian idea of time as an absolute quantity that flows on its own, along with the idea that time is the fourth dimension of spacetime, are incorrect. They propose to replace these concepts of time with a view that corresponds more accurately to the physical world: time as a measure of the numerical order of change.
This view doesn’t mean that time does not exist, but that time has more to do with space than with the idea of an absolute time. The Daily Galaxy via physorg.com and physicsessays.org. Particle Decays Point to an Arrow of Time. +Enlarge image Time moves irrevocably in one direction. Things get old, decay, and fall apart, but they rarely ever reassemble and grow young. But at the particle level, time’s arrow is not so clearly defined. Most collisions and other particle interactions look the same whether run forwards or backwards.
Physicists have, however, identified a few reactions that appear to change when time is reversed, but the reasoning has assumed certain relations between fundamental symmetries of particle physics. The BaBar collaboration has now observed time-reversal violation directly and unambiguously in decays of B mesons. In trying to understand the nature of particle interactions, observing the behavior of those interactions under different symmetry transformations has proven invaluable in formulating and verifying the fundamental theory. It is, however, possible to infer time-reversal violation (TRV) through observations of CP violation in K and B meson decays using the CPT theorem. References. Icists continue work to abolish time as fourth dimension of space. (Phys.org) -- Philosophers have debated the nature of time long before Einstein and modern physics.
But in the 106 years since Einstein, the prevailing view in physics has been that time serves as the fourth dimension of space, an arena represented mathematically as 4D Minkowski spacetime. However, some scientists, including Amrit Sorli and Davide Fiscaletti, founders of the Space Life Institute in Slovenia, argue that time exists completely independent from space. In a new study, Sorli and Fiscaletti have shown that two phenomena of special relativity - time dilation and length contraction - can be better described within the framework of a 3D space with time as the quantity used to measure change (i.e., photon motion) in this space.
The scientists have published their article in a recent issue of Physics Essays. “With clocks we measure the numerical order of motion in 3D space,” Sorli told Phys.org.

If he’d been born with one less ‘l’ his name would have been a spooky resonance with his interest in time.
Craig Callender is a groove sensation in metaphysics and the philosophy of science. He wrote the Oxford Handbook on Philosophy of Time last year and his other books include Introducing Time, Time Reality and Experience and a co-edited volume Physics Meets Philosophy at the Planck Scale. Like all time lords past present and future he neither stops brooding on time and physics nor eats meat. 3:AM: You’re a philosopher of science, physics and metaphysics.
Were you always interested in philosophising? As a child did you brood a lot about the existence of time and what happened before the big bang and stuff like that? Looking back, I do attribute a lot to the fact that my mom was and is obsessed with sci-fi. 3:AM: One of the big issues you are interested in is the scope of metaphysics.
