Is it possible that time is real, and that the laws of physics are not fixed? Lee Smolin, A C Grayling, Gillian Tett, and Bronwen Maddox explore the implications of such a profound re-think of the natural and social sciences, and consider how it might impact the way we think about surviving the future.

I once knew a physicist that was working on the idea that time is our awareness of the expansion of space. He passed away before publishing anything. I didn't understand his explanations, but I remember him saying that Einsteins space time is incomplete. That in fact it's "expanding space time". Space and time are different sides of the same thing because space is expanding and creates "quantum holes" which must be filled. The holes being filled created by space expanding is what we feel as time because these "quantum holes" allow us to go from point A to point B in space, or some such craziness that I don't understand. I also remember him saying something about if space didn't expand we could not travel through it. It would be like a solid and there could be no motion, energy or time. He claimed to have the math, but it sounds crazy to me.

Good point, it got me thinking. I wonder if those "quantum holes" are some how linked to the Laws of Thermodynamics, in respect of entropy which is another way of looking at time. It is interesting that one of the problems of physics in general, was to satisfactorily unify the laws - Unified Field Theory, as Relativity is a concept of the "very big" compared to Quantum Mechanics of the "very small". It is sad that the physicist you knew passed away. He might have been onto something.

I see time as a sequence of states that make it appear to our minds as time. ...and that is why rewinding of time is not possible. If motion is frozen(all vectors of forces still in force) then 'time' also freezes. Thus time is a perception not an entity. Time is absolute. but he says moment to moment!?

What I find refreshing about this new theory is it offers hope. The current mainstream model, that everything already exists ultimately leads to the absurd notion that everything is already fixed in place, which philosophically is fatalism. Fatalism really has no place for God or free will. The universe is living. Quantum mechanics shows us this. Bravo!

Dr. Smolin, like a symphony conductor, disciplines his orchestra of ideas to a cresendo but he forgot his conductor baton and he should have one to occupy his left hand. Regardless, his revelation is music to my ears. The symphony remains unfinished but with agency and novelty we face the danger and opportunity of today's red flag world with a modicum of encouragement. The future is not fixed, we have agency, creativity and force. We find courage in Dr. Smolin's resolve that we have agency over the emergent future, we can impact experience, one person makes a difference. Timeless truth mutates and reverses into the truth of evolution in time. It may be an evolving pattern set of fractal developments expanding previous patterns and rolling out constant variation in an expanding and changing reality. My intuition is that even our precious self is a process, a changing, moving fountain of waves, continually transcending past structure. Thank you Dr. Smolin!

I have not read the book, but what I understood from this short introduction is not that Truths are transient, but rather that Truth evolves (i.e., grows) in the presence of time. An example is the idea that the laws of Newtonian physics are eternally true, yet the passage of time has revealed a contradictory set of atomic Truths - which are also eternal. More simply, in a relativistic universe a thing may at the same time be both infinitely large AND infinitely small, depending on your measuring reference. The passage of time reveals new measuring references - and therefore there can be no timeless truths.

The idea is that time is a construct of our consciousness should not be avoided because of fear. The idea has great implications yes but none that would affect us in our experience of our physical world because it exists for us in this existence and has great implications for us regardless of if time is just a limitation/ability of our consciousness. Our world and universe is ours regardless of if it has any implications for anyone else.

For a lay-person that is very satisfying to grasp; mathematics is not sufficient in modelling reality and therefore has to make concessions one of which is that time, in the human-experience-sense is a fallacy. What makes this proposition even more interesting is the propensity for humans for: Dogma, and acceptance of Approximations or indeed complete exclusion, to make theories fit et. al.

Elementary particles can move from A to B and immediately back to position A without violating the laws of physics. The problem is, at the macro level, the probability that all the extremely huge number of particles will move back to A at the same time is basically 0. Hence time only moves forward for us.

that explains why we don't see things "rewinding" or going backwards in time on the macro level, but it doesn't necessarily explain why we live or experience things moment-to-moment, which is the problem he was trying to tackle. if relativity proposes that time and space act as part of one continuum in the natural world, how come we are able to differentiate our "present" self from our past? why is it that we experience time as a narrative flow of events instead of existing as a simultaneous amalgamation of past, present, and future? how are we able to differentiate now from before? most people are content to say that we are physically constrained to view reality in this way, but he obviously wanted to peer deeper and have a fundamental understanding as to WHAT makes us view reality moment to moment.

Exactly. I would add that time is real, immutable and unidirectional, a fundamental discreet element of natural law, buttressed by observable irreversible biological processes and measurable through observance of repetitive motions of objects in the universe, chemical processes, electrical reactance & capacitive decay etc. A guiding principle of logic: one cannot measure something (with repeatable, recordable, empirical demonstrable cross-referenceable results) and then turn around and claim that it does not exist. ⏳

Concepts can, at best, create an imperfect mirror of experience. The comforting concepts of entity and agency have been traditionally used to create man's conceptual universe. Since the symbol is not "that for which it stands", it is the usefulness of the pattern created by the concepts that matters more than the so-called objective truth of a concept. The relative merits of these patterns can be assessed by science. The Buddhists are right in that the only way to apprehend reality directly is "without thought-coverings" (without concepts).

I recently viewed Brian Greene's B-Theory of Time. In it, he claims that time does not flow moment by moment from the future through the present and into the past, but that each moment eternally exists in the universe around us as does space. For instance, a particular one occurring on the night of December 31, 1999. Now my question is this: If this is true, doesn't the audience think we could use an observatory computer to calculate the exact coordinates in the Milky Way of the Earth on a given moment on that date, and venture there, and thereafter revisit it? Of course. But in reality, when we get there, it's not there. Why not? We arrived at the planet's correct spatial coordinates--but not its right TEMPORAL coordinates! To do so, we need to GO BACK IN TIME to that desired moment. That proves the moment we desire to relive resides in the PAST. In conclusion, what we must do from this time forward is no longer philosophize that the flow of time is an illusion, but search with devices like the LHC at CERN for a particle whose function constitutes the physical basis for time.

Might the "now" moment be how decoherence is expressed in the time dimension of space-time? So, in space we experience solid matter (as opposed to the wave it emerged from) and in time we experience the "now". The implication would be that time is emergent from mass, not fundamental. Also, the arrow of time would therefore be the result of our continuously expanding universe, which in turn "stretches" all matter, which in turn generates a continuous flow of new "now" moments. Another implication of this way of thinking is that entropy is the result of our expanding universe.

My view is that there are two types of time. 1. Periodic (clock)time which has at its base a circular argument which cannot be usefully extrapolated on beyond a certain technological point and is a social construct. 2. "Lived time" which encapsulates aging, memory, and history, which animals experience too. Other than that there is the present and a succession of the present. My present is someone else's history (maybe), Seemingly cosmology which contains any assumptions is merely the extrapolation on the effects of radiation encountering reflective surfaces.

It's clear that there is some natural progression to the universe, which is the thing we're tempted to call time, but think of it by analogy with an ordered set: there is an infinite set composed of elements (states of the universe) whereby there is a self-referential relation (evolving) among elements. Timeless or temporal is a matter of perspective (the set as a whole vs. from an element of the set)

Interesting that Smolin called his argument for Type 2 Naturalism a scientific one, but justified it on the emotional grounds that it would change our attitudes to everyday and long term events, and give us a morale boost. As for the economic impacts, I don't see the relevance. It's been clear for some time that activity in the market can change the way the market behaves, and that a major mistake economists made was in treating people as rational actors. In that sense, economics got there first...

Could the mathematics of quantum mechanics represent the physics of ‘time’ as a geometrical process with classical physics representing processes over a period of time as in Newton’s differential equations? What we see and feel as ‘time’ is formed by the spontaneous absorption and emission of photon energy. In such a theory we would have an emergent future unfolding with each photon electron coupling or dipole moment. The wave-particle duality of light and matter in the form of electrons is forming a blank canvas that we can interact with! We are always in ‘the moment of now’ in the centre of our own reference frame as an interactive part of this process!

There's a paradox in Lee Smolin's thinking: if the laws are subject to change and there's no law that is timeless then this law is subject to change too. In other words the law that laws are not timeless should not be timeless too. And that means that the law that laws are not timeless may be timeless which is contradiction.

If yes, is it consistent? If yes, then the laws are incomplete.

Jae Kwon "If we want to believe that our system of physics is consistent, then well, our laws must be incomplete." That does not follow at all. They could be consistent and complete, there is nothing to prohibit that. You are attempting to apply deductive restraint to empirical observation when it simply doesn't apply. "Are the laws (axioms) of our universe such that it can describe the natural numbers?" First off that is a false analogy, laws are not equivalent to axioms. And second I really don't even understand the question, you have it entirely backwards. Laws don't describe numbers, numbers describe the laws. I think your implication is that numbers are directly derived from nature, and since math is incomplete, so is physics. The problem is that your assumption is completely false, math is not derived from nature and this is demonstrable.

He mentioned Leibniz and Newton, but he could/should have mentioned Kant. Time and space are a priori categories of the mind: They are "in here," not "out there." Kant writes, e.g, "Space is not something objective and real, nor a substance, nor an accident, nor a relation; instead, it is subjective and ideal, and originates from the mind’s nature in accord with a stable law as a scheme, as it were, for coordinating everything sensed externally" (Ak 2: 403).

It triggers me when people use that Einstein quote "past, present and future are a persistent illusion." to support the bizarre claim that time itself is an illusion and that Einstein said so. The only thing meant by that is with respect to the remarkably small differential in speeds we experience, there by placing all of us within the same frame of reference by common measures / perceptions with respect to past, present and future. He WAS NOT saying that past, present and future are actually illusions themselves, but that the idea them being invariant is an "illusion", and add nothing physically in the "playing out" of causation. Only sentiment beings have concern of compared measures, physics itself not so much :/ Note also this quote of his is from a letter of condolence he wrote regarding the passing of someone.

Based on this very brief summary of the book, I take it the proposition put forth is that we must not believe in causal determinism because that will induce hopelessness and inaction regarding the ecological future of the planet. First, a type of relativism seems to be proposed: the physical laws are not timeless, but only valid for a given time (span) and place. This contains the same fallacy as any other relativist position, namely, if there are no absolute laws, then "There are no absolute laws," is not an absolute law either. More importantly, a belief in determinism does not cause a person to stop functioning the way anyone else functions. One does not become will-paralyzed upon adopting belief in determinism. But if we assume the laws of physics will not hold, then how exactly do we plan our strategies and actions to bring about a desired end? If we assume impermanent laws, that would seem to induce the greater feeling of hopelessness and inability to cope. Further, though an academician may be a determinist (Naturalist 1), he will be aware of the problem of induction ("grue" and "bleen") which will prevent him from acting as though he knows absolute laws. I think the basic flaws here are the suggestion that a determinist view of the universe prevents exercise of will, and the failure to recognize that belief in determinism is tempered, as it were, by a good healthy sense of doubt about whether it is true and if so, what its implications are for the individual and collective mind. I also think that lack of action for the environment is based on a too-great faith in science, which is seen as a force so powerful that it will be a sort of deus ex machina which will step in and save the day regardless what we do in the present.

@@tonyjackson4099 I see how you may be confused, my comment in this thread was after a rather lengthy diatribe I posted in the main comments section, so this comment here is out of context. If you care to read that other one , you will see that your conclusion is wrong, but, based on the one liner I posted here, I see your point. No, I am not affiliated with any political leaning. Truth in science, common sense, yes, paid research leading to political propaganda, not so much. Climate science is more like a religious dogma than science these days. If you do not point to man as being the only cause for climate change, then you cannot get published nor funded, so it is hard to blame them for trying to make a living, however they must be held accountable, as they harm the public trust, just like bad cops and crooked politicians. If you want a more complete answer about why and how climate science went so wrong, try the Suspicious Observers channel. They go to great lengths to hold scientists accountable for publishing truth over fiction. Yes, I get the mainstream agenda, pollution=Bad. However, we are not even a close second to the real driver of natural events on this world. The sun has a trillion times more to do with it, and climate science refuses to include any of its influence in their models. It's like doing research on oceanic conditions and ignoring the salt content.... The real reason they don't look at the sun is a genuine conspiracy theory proven as true crime. Very sad, and very nefarious. For example, what did the astronauts go to the Moon to look for? Geologic evidence of the Sun misbehaving. They found more than they bargained for. Glass rocks and spherules with fission tracks, transuranic elements, etc., all leading to the conclusion that we are toast. Do you think they want Anyone looking at the Sun? No, because then we would panic, and that would hamper their plans. Building deep underground , interconnected shelters and stockpiling them, and so on. They do not want to lose control if the truth gets out. Every 10-12,000 years, the Sun goes boom and we get a reset that makes what they are calling " the great reset" look like a pimple in the whole of a human's life cycle. You can stick your head in the sand, write me off as a nutcase, ignore me, or go looking to verify what I have said. I warn you though, the truth is far worse than the little I have hinted at here, and you may just want to take the blue pill on this one, Neo... good luck fellow human.

I think some here don't understand the value in this new way to think about time. We haven't made very many leaps in physics. Maybe the problem is that we're looking at it from the wrong angle. You don't have to play around with the thought experiment as if it were true. I recommend exploring the idea like you were exploring a new philosophy.

Definitely i prefer, widely, the Julian Barbour idea of time. This is not a paradigm change, he is using time concept exactly in the way that Newton does: as an absolute framework, Julian Barbour already talked about how Leibniz attack this topic. And the concept of time as an illusion means that scientist are confusing the nature of time with the perception of time, that is a psychology issue more than a phisics issue. The idea of the "evolution" of nature laws is very interesting.

A lot of measurements are made in science. Time is a construct of measurement. It has a preset moment and it had a lot of previous moments and it is logical that there will be additional moments in the future. Time is malleable as Einstein illustrated that it is a part of spacetime.

The first sentence contains two premises, and there are four possibilities. Either time is real or it is not. Either the laws of physics are fixed or they are not. By linking the premises, Smolin appears to have reduced the options to two. It seems to me there is no reason not to believe that time is real, and the laws of physics are fixed. That, as an aside, does not in any way imply the future is fixed. There is nothing in physics that disallows probabilities, and quantum mechanics, as an example, is full of them. If we allow probabilities, where, for example, a Higgs boson has more than one possible degradation route which it chooses at random but nevertheless according to a probability rule, then there dis no possibility that the future is absolutely fixed, nevertheless, if you make enough Higgs bosons today or in fifty years, you should still get the same distribution.

Sure, what you are describing sounds very much to me like the indigenous view of time. Buts it's still I think somewhat problematic. Hense, the epilogue in Smolin's book. Doesn't the eternal timeless universe also help to justify the creation of strong AI, even when we still know so little about the human brain (see the failures of the Human Brain Project), as we view math more real than anything? And some might say by much of science rejecting the Now, it also helps to justify eschatological worldviews too. AGW is the elephant in the room here...

#Gerard van Reekum Smolin's use of the word "universe" there is a question of definition - he is defining "the universe" as "the one thing that cannot be caused by or explained by something external to it". This may or may not coincide with what others call "the universe", but he has defined his use of it, and it is not a definition unique to himself, in fact it goes back at least to Spinoza.
