Atlantic asks, Is time real?

Spread the love

Dan Falk here:

Last month, about 60 physicists, along with a handful of philosophers and researchers from other branches of science, gathered at the Perimeter Institute for Theoretical Physics in Waterloo, Canada, to debate this question at the Time in Cosmology conference. The conference was co-organized by the physicist Lee Smolin, an outspoken critic of the block-universe idea (among other topics). His position is spelled out for a lay audience in Time Reborn and in a more technical work, The Singular Universe and the Reality of Time, co-authored with the philosopher Roberto Mangabeira Unger, who was also a co-organizer of the conference. In the latter work, mirroring Elitzur’s sentiments about the future’s lack of concreteness, Smolin wrote: “The future is not now real and there can be no definite facts of the matter about the future.” What is real is “the process by which future events are generated out of present events,” he said at the conference.

These people are mainly a summer phenomenon.

    Interesting quote: I’m writing a post for the Big Bang thread on this subject right now

    Time is real and PHYSICAL. You can prove that yourself from Einstein’s own equations. See: “Beyond Einstein: non-local physics” by Brian Fraser (2015)

    The free 22 page paper can be downloaded from: The .html file gives a link to the .pdf file but the former has additional information, and many more links and insights.

    Einstein’s concept of time was in conflict with leading philosophers concept of time.

    Einstein vs Bergson, science vs philosophy and the meaning of time – Wednesday 24 June 2015
    Excerpt: The meeting of April 6 was supposed to be a cordial affair, though it ended up being anything but.
    ‘I have to say that day exploded and it was referenced over and over again in the 20th century,’ says Canales. ‘The key sentence was something that Einstein said: “The time of the philosophers did not exist.”’
    It’s hard to know whether Bergson was expecting such a sharp jab. In just one sentence, Bergson’s notion of duration—a major part of his thesis on time—was dealt a mortal blow.
    As Canales reads it, the line was carefully crafted for maximum impact.
    ‘What he meant was that philosophers frequently based their stories on a psychological approach and [new] physical knowledge showed that these philosophical approaches were nothing more than errors of the mind.’
    The night would only get worse.
    ‘This was extremely scandalous,’ says Canales. ‘Einstein had been invited by philosophers to speak at their society, and you had this physicist say very clearly that their time did not exist.’
    Bergson was outraged, but the philosopher did not take it lying down. A few months later Einstein was awarded the Nobel Prize for the discovery of the law of photoelectric effect, an area of science that Canales noted, ‘hardly jolted the public’s imagination’. In truth, Einstein coveted recognition for his work on relativity.
    Bergson inflicted some return humiliation of his own. By casting doubt on Einstein’s theoretical trajectory, Bergson dissuaded the committee from awarding the prize for relativity. In 1922, the jury was still out on the correct interpretation of time.
    So began a dispute that festered for years and played into the larger rift between physics and philosophy, science and the humanities.
    Bergson was fond of saying that time was the experience of waiting for a lump of sugar to dissolve in a glass of water. It was a declaration that one could not talk about time without reference to human consciousness and human perception. Einstein would say that time is what clocks measure. Bergson would no doubt ask why we build clocks in the first place.
    ‘He argued that if we didn’t have a prior sense of time we wouldn’t have been led to build clocks and we wouldn’t even use them … unless we wanted to go places and to events that mattered,’ says Canales. ‘You can see that their points of view were very different.’
    In a theoretical nutshell this expressed perfectly the division between lived time and spacetime: subjective experience versus objective reality.,,,
    Just when Einstein thought he had it worked out, along came the discovery of quantum theory and with it the possibility of a Bergsonian universe of indeterminacy and change. God did, it seems, play dice with the universe, contra to Einstein’s famous aphorism.
    Some supporters went as far as to say that Bergson’s earlier work anticipated the quantum revolution of Niels Bohr and Werner Heisenberg by four decades or more.
    Canales quotes the literary critic Andre Rousseaux, writing at the time of Bergson’s death.
    ‘The Bergson revolution will be doubled by a scientific revolution that, on its own, would have demanded the philosophical revolution that Bergson led, even if he had not done it.’
    Was Bergson right after all? Time will tell.

    Advances in quantum mechanics have validated the philosophers ‘psychological approach’ to understanding time and has invalidated Einstein’s relativistic time as to being the absolute frame of reference for reality.

    LIVING IN A QUANTUM WORLD – Vlatko Vedral – 2011
    Excerpt: Thus, the fact that quantum mechanics applies on all scales forces us to confront the theory’s deepest mysteries. We cannot simply write them off as mere details that matter only on the very smallest scales. For instance, space and time are two of the most fundamental classical concepts, but according to quantum mechanics they are secondary. The entanglements are primary. They interconnect quantum systems without reference to space and time. If there were a dividing line between the quantum and the classical worlds, we could use the space and time of the classical world to provide a framework for describing quantum processes. But without such a dividing line—and, indeed, with­out a truly classical world—we lose this framework. We must explain space and time (4D space-time) as somehow emerging from fundamentally spaceless and timeless physics.

    New Mind-blowing Experiment Confirms That Reality Doesn’t Exist If You Are Not Looking at It – June 3, 2015
    Excerpt: The results of the Australian scientists’ experiment, which were published in the journal Nature Physics, show that this choice is determined by the way the object is measured, which is in accordance with what quantum theory predicts.
    “It proves that measurement is everything. At the quantum level, reality does not exist if you are not looking at it,” said lead researcher Dr. Andrew Truscott in a press release.,,,
    “The atoms did not travel from A to B. It was only when they were measured at the end of the journey that their wave-like or particle-like behavior was brought into existence,” he said.
    Thus, this experiment adds to the validity of the quantum theory and provides new evidence to the idea that reality doesn’t exist without an observer.

    Lecture 11: Decoherence and Hidden Variables – Scott Aaronson – MIT associate Professor
    Excerpt: “Look, we all have fun ridiculing the creationists who think the world sprang into existence on October 23, 4004 BC at 9AM (presumably Babylonian time), with the fossils already in the ground, light from distant stars heading toward us, etc. But if we accept the usual picture of quantum mechanics, then in a certain sense the situation is far worse: the world (as you experience it) might as well not have existed 10^-43 seconds ago!”

    Quotes of note:

    ‘In the ‘spirit world,,, instantly, there was no sense of time. See, everything on earth is related to time. You got up this morning, you are going to go to bed tonight. Something is new, it will get old. Something is born, it’s going to die. Everything on the physical plane is relative to time, but everything in the spiritual plane is relative to eternity. Instantly I was in total consciousness and awareness of eternity, and you and I as we live in this earth cannot even comprehend it, because everything that we have here is filled within the veil of the temporal life. In the spirit life that is more real than anything else and it is awesome. Eternity as a concept is awesome. There is no such thing as time. I knew that whatever happened was going to go on and on.’
    In The Presence Of Almighty God – The NDE of Mickey Robinson – video (testimony starts at 27:45 minute mark)

    ‘When you die, you enter eternity. It feels like you were always there, and you will always be there. You realize that existence on Earth is only just a brief instant.’
    Dr. Ken Ring – has extensively studied Near Death Experiences

    ‘Earthly time has no meaning in the spirit realm. There is no concept of before or after. Everything – past, present, future – exists simultaneously.’
    – Kimberly Clark Sharp – Near Death Experiencer

    ‘There is no way to tell whether minutes, hours or years go by. Existence is the only reality and it is inseparable from the eternal now.’
    – John Star – NDE Experiencer

    “I started to move toward the light. The way I moved, the physics, was completely different than it is here on Earth. It was something I had never felt before and never felt since. It was a whole different sensation of motion. I obviously wasn’t walking or skipping or crawling. I was not floating. I was flowing. I was flowing toward the light. I was accelerating and I knew I was accelerating, but then again, I didn’t really feel the acceleration. I just knew I was accelerating toward the light. Again, the physics was different – the physics of motion of time, space, travel. It was completely different in that tunnel, than it is here on Earth. I came out into the light and when I came out into the light, I realized that I was in heaven.”
    Barbara Springer – Near Death Experience – The Tunnel – video

    “Regardless, it is impossible for me to adequately describe what I saw and felt. When I try to recount my experiences now, the description feels very pale. I feel as though I’m trying to describe a three-dimensional experience while living in a two-dimensional world. The appropriate words, descriptions and concepts don’t even exist in our current language. I have subsequently read the accounts of other people’s near-death experiences and their portrayals of heaven and I able to see the same limitations in their descriptions and vocabulary that I see in my own.”
    Mary C. Neal, MD – To Heaven And Back pg. 71

    “Well, when I was taking geometry, they always told me there were only three dimensions, and I always just accepted that. But they were wrong. There are more… And that is why so hard for me to tell you this. I have to describe with words that are three-dimensional. That’s as close as I can get to it, but it’s really not adequate.”

    If “there can be no definite facts of the matter about the future” then we can’t say there will be a solar eclipse on Aug 21, 2017.
