INTRO: It has become a dominant view in the philosophy of time that Einstein’s Theory of Relativity showed that the passage of time is an illusion, and that in fact the past, present, and future all coexist. But the philosopher Henri Bergson, a contemporary of Einstein’s, was a strong critic of the theory’s portrayal of time. Bergson emphasised the cultural and technological context in which Einstein formulated relativity and argued that a theory of time that relies on clocks but doesn’t understand their history and significance, is incomplete, writes Jimena Canales.

As you explore in your book The Physicist and The Philosopher, there was a contemporary of Einstein’s, the philosopher Henri Bergson, who didn’t buy the relativistic picture of time. What was Bergson’s main objection?

Bergson’s main objection against Einstein’s work was that it was smuggling in a certain metaphysics into science, without acknowledging its presence. This metaphysics was nothing extraordinary—just the contrary—it was basically run-off-the-mill materialistic. Bergson ended his controversial and complex book with a simple sentence, “Einstein is the continuator of Descartes.” Bergson’s objections were therefore more than simply objections about the Einsteinian notion of time. They were about the role of science vis-à-vis other forms of knowledge. Bergson felt he had a “duty” to defend these other forms of knowledge from being snuffed out by some of the claims made in the name of science. “The idea that science and philosophy are different disciplines meant to complement each other,” he wrote, “arouses the desire and also imposes on us the duty to proceed to a confrontation.”

[...] Bergson has been frequently interpreted as aiming to recuperate the feeling of time’s passage which Einstein considered illusory. Einstein, in an entry of his travel diary commenting on Bergson’s Duration and Simultaneity read him as a philosopher who “objectivized” psychological aspects of time. Heidegger also portrayed him this way when he explained that the term “time” in Being and Time “means neither the calculated time of the ‘clock,’ nor ‘lived time’ in the sense of Bergson and others.” Those interpretations are much too simplistic. Bergson was interested in investigating the area where the subjective and the objective meet and the area where life and matter connect. He did not want to stand on either dichotomy. His most significant contribution was to analyse how those concepts were “riveted” to each other and why.

[...] It is a mistake to ask Bergson for a single unchanging definition of time, because time changes throughout time: “time is what happens, and also what makes everything happen”. (“Le temps est ce qui se fait, et même ce qui fait que tout se fait.”) Consider, for example, how different pre-modern notions of time are from ours....

[...] Einstein’s definition of time has none of these radical elements and might even be responsible for leading us to forget about them. In his work, time is closely tied to what clocks measure. To Bergson’s dismay, it did not include clock makers, clock users and those events external to the clock that make time meaningful...

Do you think contemporary philosophers should, like Bergson, question the picture of reality that theoretical physics is offering us, and focus on the conceptual and perceptual preconditions of science?

A central motivation of my work is to point out that in addition to knowledge, we need knowledge about knowledge—the latter can help us obtain a better understanding that includes the sciences, arts and humanities. We have first order knowledge of things, a second order one about things, but we can also begin to develop a third order knowledge that includes knowledge about itself... (MORE - missing details)
The flow of time is inextricably embedded inside our whole experience. Thoughts make sense because they come one after another. Perceptions occur because there is a sequence in their happening. Feelings? What else are they but the flux of a certain sensation or tone in our own chest?

There is succession and movement to the state of being conscious. Everything is transient and passing. Even the things that persist and endure do so against the current of happening around and thru it. Time is the name we put on this inherent ongoingness of our lives. There is no such thing as meaning or story without it.

Far as I know there are two normals for time in this universe….it exists for some particles and not for others. That doesn’t seem possible so is something not right?
To put it into perspective... Does an "Inch" exist?
Time is a dimension, it's existance is as a measurement. I would not suggest it's a corporeal entity.

Does past, present and future exist at the same time? Well thats dependent on how you measure it. In a volume of vaccum space there should technically be no passage of time, as if the vaccum truly has no background energy, there would be nothing to measure time with. In that instance you could imply that past, present and future are all one in the same. However if you were in the vaccum, with or without a watch, there would be a passage of time based off of your observation as a "timekeeper". (Since you're observation would be how the vaccum would keep time)

If someone was to point out, that while you are doing an experiment with a vaccum in a box time still passes by, that is clearly a Relativistic statement.

If you take a neutron it will most likely decay into something else within about 2 minutes.
If you take a proton it will most likely not decay (ever).
Suggestion .. time passes for both particles but you only see the effect on neutrons. Like immortality isn't 'not having time' .. its just more of it to do immortal type things in.
Like an observable universe, could there be an observable time? Maybe measurable is a better word but I’m hinting at a limit to how far back in time we can measure. Are we prevented from going any further into the past than the BB? If so why? Easiest answer is because that was the beginning but why isn’t it possible we could be in a new universe that was preceded by an older version that we cannot access or view?

What cosmologists believe depends upon what falls out of their personal choices in competing concepts. So none of them really know. It's just multiple strains of mathematically driven and expressed speculation.

For instance, those who believe in cosmological inflation contend that it preceded the Big Bang. In contrast, the classic spacetime view ("nothing beyond the South or North Pole analogy") treats so-called temporal changes as the co-existing differences in the make-up of a geometrical structure. Nothing beyond where everything narrows down to the initial singularity, if the latter, older view is what they still conceive a starting state as. And so-forth with respect to whatever they're playing with...


The Myth Of The Beginning Of Time
https://www.scientificamerican.com/artic...e-2006-02/

EXCERPT: So, when did time begin? Science does not have a conclusive answer yet, but at least two potentially testable theories [loop-quantum gravity & string theory] plausibly hold that the universe--and therefore time--existed well before the big bang. If either scenario is right, the cosmos has always been in existence and, even if it recollapses one day, will never end.

Cosmic inflation preceded the Big Bang

Did Time Have A Beginning?
https://www.forbes.com/sites/startswitha...604ca3513b

EXCERPT: [...] Like many great discoveries in science, this [cosmic inflation] leads to a slew of delightful new questions, including:

[*] Was the inflationary state a constant one? We do not know whether the Universe inflated at the same rate everywhere, or whether it inflated for long periods of time. If the Universe inflated in ways that changed very quickly from one moment to the next, varying from location-to-location, it might still have the properties we observe it to have today.
[*] Did the inflationary state last forever, going backwards in time? Inflation certainly has the potential to be an eternal state; we believe in the regions where it doesn't end in a hot Big Bang, it continues eternally into the future. But could it have also been eternal to the past? With nothing forbidding it, we must consider the possibility.
[*] Is inflation connected to dark energy, which is also a form of exponential expansion? Although they're different in scale and magnitude, the early-stage cosmic inflation and the late-stage dark energy both give the same mathematical form for the Universe's expansion. Are these two stages related, and will our future expansion increase in strength and rejuvenate our Universe, like some sort of cosmic cycle?

Mind-Bending study suggests time did actually exist before the Big Bang
https://www.sciencealert.com/mind-bendin...e-big-bang

EXCERPTS: Hawking only recently gave his own take in an interview with Neil deGrasse Tyson, where he likened the space-time dimensions of the Big Bang to the South Pole. "There is nothing south of the South Pole, so there was nothing around before the Big Bang," he said.

But other physicists have argued there's something beyond the Big Bang. Some propose that there is a mirror Universe on the other side, where time moves backwards. Others argue in favour of a rebounding Universe.

[...] What this essentially adds up to is a description of the Big Bang where physics remains intact as the stage it acts upon reorientates.

Rather than a singularity, the team call this a Janus Point, named after the Roman god with two faces.

The relative positions and scales of the stuff that makes up the Universe effectively flatten into a two-dimensional pancake as we rewind time. Passing through the Janus Point, that pancake turns 3D again, only back-to-front.

What that means in physical terms is hard to say, but the researchers believe it could have profound implications on symmetry in particle physics, maybe even producing a Universe based primarily on antimatter.

While the idea of a flipped Universe is old news, the approach of working around the singularity problem in this particular way is novel.

Layman's armchair perspective: Got me thinking of those vids of astronauts in space playing with a blob of weightless floating water and watching it change shape constantly but stay together. If the universe was a wriggly shape shifting blob then could it take on different looks over the aeons and we just happen to be at a time and place where it appears like expansion taking place?

Who knows, a tiny part of the universe is all we have empirical access to, inferences made from that. A messy shape seems less artificial compared to the neat geometrical forms that are entertained (from sphere to torus to horn, etc).
