“….. although, you could argue that time actually goes “backwards” naturally, ie, as it ceases to “exist” for an object at light speed zero size infinite mass, & most strongly affects low speed low mass objects, then everything on a timeline should be measured back from that “zero” point of light speed/no time/infinite mass, not “towards it” ….”
“time” is “places in space, relative to the observer & the observer’s mass/speed” njoi! Billie
A new paper (below) … “Why Does Time Move Forward, Not Backward” – suggests that the arrow of time — a term given to the forward direction of time — is driven by gravity and, therefore, an inescapable result of the fundamental laws of physics in our universe.
……. oh, you mean the same thing Einstein said anyway, ie, “that any matter nearing or at lightspeed nears or has infinite mass, zero size & zero passage of time relative to the universe around it” (paraphrased), because, uh, that DOES rather imply that time is a gravitationally affected scenario, as indeed is every other “dimension” in Einsteinien space/time, still, #savesthemhavingtodipintotheirtrustfunds
Hey Billie. I enjoyed your thoughts / comment that “you could argue that time actually goes backwards”. It should be a widely discussed topic ….. if anyone was game enough to put forward an opinion. I would think most folk either aren’t smart enough or brave enough to take it / you on, or simply can’t comprehend the point.
cheers Darren, &, yeah, i’ve noticed that, ie, about the only “replies” i ever get to such are attempts at put-downs from the trolls that have no cognitive thought processes or alternatives of any kind to contribute but whom merely (& usually inaccurately) adhere to whatever “flavour of the month” mainstream science has currently proclaimed, much as religious fanatics quote the bible to prop up their weak thinking, or simply claim “bullshit you’r an idiot” whilst they, again, offer zero alternatives or any points at all, valid or otherwise, ie, that merely act like dumb-arses at school calling names because ya beat them at #maths #science #literature #metalwork #carpentry #economics whatever, like a flock of teensy “mainstream anti-bodies”, clustering around & trying to shout-down any “intruder”, funny enough in its own way, but it does make me rather doubt the sustainability & viability of the Species as is… Slainte!
Most of our lives revolve around time, from the instant our alarm clocks go off to attending afternoon appointments to the moment we call bedtime. Tick tock. But what exactly is time, and why is it always marching forward? A new paper suggests that the arrow of time — a term given to the forward direction of time — is driven by gravity and, therefore, an inescapable result of the fundamental laws of physics in our universe. However, “the laws of physics are ‘time-reversal invariant,’ which means that all the many phenomena we understand and describe through the laws of physics respect these same laws too if ‘played backwards’ like a movie played in rewind,” Dr. Flavio Mercati, a researcher at the Perimeter Institute for Theoretical Physics in Ontario, Canada, told The Huffington Post in an email. “This seems puzzling, considering that we see so many phenomena unfolding only in one way.”
“although, you could argue that time actually goes “backwards” naturally, ie, as it ceases to “exist” for an object at light speed zero size infinite mass, & most strongly affects low speed low mass objects (such as the Earth, the Sun, Humans etc), then everything on a timeline should be measured back from that “zero” point of light speed/no time/infinite mass, not “towards it”, oh, & remember, black is white, white is black & you ought therefore never use zebra crossings”
Time flies straight ahead like an arrow, never backtracking, and a Perimeter postdoc has co-authored a Physical Review Letters paper that offers an explanation as to why. Physicists have long sought to explain why the arrow of time always flies from past through present to future. One explanation for this, writes Perimeter Templeton Frontiers Fellow Flavio Mercati and his co-authors in a new Physical Review Letters paper, could be intrinsically tied to the complexity of our universe. The arrow of time is often explained by the so-called “past hypothesis,” which presumes that the universe began with a very special low-entropy state – a tidy scenario in which the baby universe was nicely ordered before getting progressively messier. But our universe doesn’t seem to get messier as it evolves; on the contrary, observations suggest it evolved from a very messy state in the past (a “plasma soup” close to thermal equilibrium) into the beautifully ordered structures seen today (galaxies, solar systems, people). The past hypothesis makes too many unreasonable assumptions about the early universe, says Mercati, and raises questions about how it became tuned with such precision. A more tenable proposal, he and co-authors Julian Barbour and Tim Koslowski suggest, is an explanation based on complexity. “The universe is a structure whose complexity is growing,” says Mercati. “The universe is made up of big galaxies separated by vast voids. In the distant past, they were more clumped together. Our conjecture is that our perception of time is the result of a law that determines an irreversible growth of complexity.” When examined through the lens of complexity, the state of the early universe seems all but special: most solutions of the dynamics evolve through a state of very low complexity, which looks special to the observers emerging later. – Colin Hunter

It is widely believed that special initial conditions must be imposed on any time-symmetric law if its solutions are to exhibit behavior of any kind that defines an “arrow of time.” We show that this is not so. The simplest nontrivial time-symmetric law that can be used to model a dynamically closed universe is the Newtonian N-body problem with vanishing total energy and angular momentum. Because of special properties of this system (likely to be shared by any law of the Universe), its typical solutions all divide at a uniquely defined point into two halves. In each, a well-defined measure of shape complexity fluctuates but grows irreversibly between rising bounds from that point. Structures that store dynamical information are created as the complexity grows and act as “records.” Each solution can be viewed as having a single past and two distinct futures emerging from it. Any internal observer must be in one half of the solution and will only be aware of the records of one branch and deduce a unique past and future direction from inspection of the available records.
