And we happen to have the ability to remember things-if we didn’t, then not only would time have no meaning, but nothing would have any meaning. We’d just be mindless automatons. And since we’d be unable to learn from experiences and unable to integrate and/or synthesize any information about the world we found ourselves in due to our lack of ability to form memories, you can be sure we wouldn’t have survived long enough to think about things like the nature of time, or even think about anything at all really.

    Spatial dimensions come in two types - curled up, and flat. Our notion of "time" comes from a third type of spatial dimension - one that is partially curled up, and in the process of 'uncurling' itself. There is always n number of spatial dimensions (3 in our case), and then a fraction of a dimension which is partially uncurled. This fraction of a spatial dimension is what we refer to as 'time'. What causes spatial dimension to uncurl? Why would a spatial dimension go from completely curled up, to completely flat? Our unoverse has 3 flat spatial dimensions, and one that is somewhere inbetween flat and curled up. Vacuum energy (virtual photons) cause curled up spatial dimensions to uncurl. Dark energy is virtual photons. Dark energy is 'time'. Virtual photons are 'time'. Time is the vacuum energy that expands space.

    I can conceive of the entire universe freezing for a billion years and then re-starting. I can also conceive of the entire universe freezing for ten seconds and then re-starting. In either case there would be absolutely no motion and nothing happening in relation to anything else in the universe while frozen. Yes, WHILE frozen! I think it makes sense that WHILE is a good word to use for this scenario and there could be different durations of a universe in the hypothetical state of no motion. If time is just defined by motion, then that implies EVEN IF the universe froze, it froze for ZERO amount of time. But this doesn't seem right! Sure, maybe the universe freezing like this is impossible. But I don't think it's logically impossible. It just hasn't happened (or maybe it happens all the time but we don't know it). I like to think of time more metaphysically. Because it seems hard to even conceive of empirical science totally ruling out a metaphysical concept of time that might be way more fundamental than psychology and laws of physics. Also, I don't think concepts like causation are coherent without time, in a metaphysical sense. They are defined by one thing preceding another. Science itself could not exist without time. I suspect time may not rely on things like causation or motion to exist. And it seems to me like existence and time are linked. If something exists for zero amount of time, is that even possible? Did it really exist? Seems way more like a logical contradiction than time going beyond motion!

    So the answer is “we do not know”. Why? Because we may (or can) never know. Why? Because is the universe eternal? Is whatever is outside the universe eternal? Then what is time really? So, time may not be and pretty much from the basic logic above cannot be “fundamental”. And that’s a problem in and of itself. What is or what does fundamental really mean anyways? Fundamental to what? Our universe? “Our” (humans ideas, thoughts, observations) of what we can measure if “information” in the universe or what made the universe or what the heck is the universe anyways? A simulation? A “natural” phenomena? A “natural” phenomena to what? Where? when, how? What is “natural” anyways? Everything? Nothing? Time is like gravity. We can observe it and experience it but can we truly measure it according to what it really is based on other factors we don’t know that may or may not have direct or indirect effects to time or gravities existence?

    How do the objects involved in these events persist from one event to another? If they're just discrete, instantaneous events, something interesting must be going on with the relations of thing x(event 1) and thing x(event 2). It's also very counterintuitive to me that an event itself can take place outside a passage of time. It seems like we're able to divide events into smaller and smaller parts which can themselves be seen as shorter events. I can't imagine an event that doesn't take any time to occur.

    @UCMQczoY37Ko55Ugmvy1sQCThat time is eternal, addresses a fundamental question of time. That is, if time had a beginning, what was, in terms of duration, before the beginning of time? That condition would be inexplicable if time had a beginning. Secondly, this would mean that everything erupted from absolute zero, no law of physics, no mathematics, no anything. That condition will never explain how and why we are here. In that case, there would no way of knowing the cause of existence. On the other hand if time is eternal, then something, whatever that might be, must have eternally existed and that will give us something to work with to study the origin of things that had a beginning.

    Decay and erosion are just a way that matter changes. (At its base nothing really changes anyway.) It feels like something called time is passing but that feeling is created by the mind/ brain. Everything is constantly changing, including us. The “past” is a memory taking place “now”, and the future is not a real thing. Everything happens NOW! Difficult to grasp I know. As for carbon dating and measuring “time” of universal expansion, we are still only measuring the change in the Carbon-14 levels and the changes in position of the stars or galaxies. And how do we describe it…relative to our revolution around the sun or the distance light travels during that revolution. Measuring motion against another motion, or other change, is all there is. And it all takes place “now”.

    Is gravity a constant? If so, then time must also be, because gravity is directly linked to time. How do you calculate the speed of gravity? The equation involves time, how long an object has been falling. What if time were variable, like in Special Relativity? Then gravity would also be variable as gauged from different inertial frames. It appears that gravitational time dilation exists, but that's a case of time being dependent on gravity, which is logical, gravity affects time, time doesn't affect gravity, you can't just travel fast and thereby alter time because inertial motion is not analogous to gravity, it's analogous to lack of motion, there's no difference, which is why all laws of physics are the same in both cases.

    I have an exciting old theory that is now an observation. There is no need to modify gravity. Less gravity accelerates time and inflates distance both of which accelerate causation making everything move faster including lightspeed while maintaining the speed of light 186,000 miles per second. The concept is so simple at least for mechanically minded people. If you change the size of a cubit, you will change the size of the house that you build with it. If instead of driving 60 kilometers an hour you drive 60 miles an hour, you will increase your speed because you increased the distance that you traveled in an hour. Then if you change from 60 miles an hour to 60 miles in half an hour, you increased your speed again because you traveled 60 miles in a faster time. General relativity is no longer a theory, it is an observation. Distance expands with less gravity and time speeds up with less gravity effectively making everything faster including light without breaking the speed of light.

    If it's fundamental then it should be measurable and observervable. Time has never been measured and it's never been observed. That "t" in all physics equations has always represented the duration of some cyclical thing - a clock. However, all clocks drift, which should be a smoking gun that clocks are incapable of measuring time. Because if time existed and clocks actually measured it, then clocks wouldn't drift at different rates depending on the clock. As such, clocks cannot be odometers that measure the progression of through time. Clocks are in fact metronomes. And just as an actual metronome is not genuinely slaved to a song being played on a piano, nor is the song slaved to the metronome. Similarly, clocks are not genuinely slaved to any rates of change that is occurring in the universe, nor is any rate of change slaved to a clock. Hence, clocks fundamentally cannot be measuring the progression of time - some physical movement from the past to the future as actual places. And since clocks are what we use the "measure" the "progression" of time. Then existence of time itself is extremely questionable.

    "The world looks significantly different depending on which time projection it is viewed in." (Naan). Of the three: Schwarzschild, proper and global, it seems that the third time should be chosen, since the asymmetry of time actually implies the accumulation of time, more precisely, history. In other words, it is the age of the system that is the determining factor for describing the physical processes occurring in the system under consideration. We can say that there is neither the present or the future, but only the evolving past.* P.S. “The direction of the process is always the loss of energy availability.”, Feynman. Thus, it is impossible to measure time even mentally experiment (without the use of clocks, instruments, phenomena ...) without energy consumption. --------------------------- *) - Ancient Roman quantum mechanics: to the question: how many eggs can you eat on an empty stomach?

    Einstein understood time better than anybody else has since. He locked it down to locality and relatively speeds of these localities to each other. Aliens travelling a millions of times faster than us on their planet in their part of the universe will experience time far more slowly than us on our planet. And they will maybe experience time shooting past in comparison to other aliens in another part of the universe on their planet travelling millions of times faster than them, where their time will be relatively slow. So locality and speed relative to one another are inextricable determinants of what we perceive as time. So time could be interpreted as fundamental, but without a 'constant' and thus beyond scientific definition or understanding.

    Time is a mental construct. If you look closely you will see that it is always determined by the motion of some physical system: the hands of a clock, the Earth's rotation, our revolution around the sun. Nowhere can we sense time in any other manner. It is always relative to something else and has no absolute reality. It is a feeling in our mind/brain and nothing more. In deep Zen meditation practiced followers can turn off the section of the mind/brain responsible for the feeling of time. The experience is amazing.

    It takes time to experience something. You didn't turn off anything. Time is independent of your state of mind. It is only your perception of time that you may be able to control. But that doesn't take meditation, it's what everyone experiences. "Time flies when you're having fun" and "a watched pot never boils" are two examples of many expressions about the phenomena. Ironically, put youself near a black hole or travel near the speed of light and time will really pass slower for you, you just won't perceive it.

    ⁠​⁠​⁠@@markstipulkoski1389Actually you would see what we refer to as “time” slow down “relative” (that word again) to the world outside your ship. Traveling near light speed actually changes your ship and everything in it so that everything moves slower, mass increases, and measuring devices with which we measure time are slowed “relative” to everything outside the ship. We don’t notice it inside the ship because everything inside has changed in the same ways. So…it turns out that any physical changes we see, such as a person aging more slowly, is due to actual physical effects of traveling near light speed, not to something called “time” slowing down. And yes, there have been studies showing that people can turn off certain areas of the brain using meditation and other methods. I experienced it myself. Then, the phrases you mentioned like “time flies” kinda helps my contentions. Our feeling of time changes as you say. To me that speaks for time being a feeling constructed by our mind/brain and not a real thing we can sense. I’ll just say time can only be measured relative to the motion of some physical system. It is never seen as an absolute “thing”. Most scientists will say they don’t know what time is because know one has ever found it. Einstein himself called it “a persistent illusion”.

    What about someone in a sensory deprivation float tank who can temporally order his series of thoughts? First, he thinks about x, then about y, then about z. What's the physical motion that ordering is made in reference to? Even just closing your eyes and counting can give you a temporal ordering, an experience in time, without a physical motion to reference.

    Someone this intelligent referring to Native Americans/Indigenous/Aboriginals as "Indian" is pretty shocking. Christopher Columbus called Natives mistakenly "Indians" because he thought he arrived in the Indies. That aside, his point about time is pretty spot on imo. Time doesn't exist, it is an invented measurement of the movement of objects relative to other objects (the Sun vs Earth). That's what we call time in the practical sense.

    "Time doesn't exist, it is an invented measurement of the movement of objects relative to other objects (the Sun vs Earth)." My thoughts are almost in agreement with your statement. To have my thoughts agree completely I would change it... Time does not exist except as a concept. The concept of time was developed by the ancient's from their observations of the relative movements of objects. These days almost all acquire the temporal concept from culture. Cheers!

    I suggest that time is imaginary. Motion (within the three spatial dimensions) is the more fundamental quality. That is to say, instead of velocity being defined as distance/time, we should be thinking of time as being defined as distance/velocity. Velocity (motion) is the more fundamental quantity. Think about that.

I think what sujok is saying - at least this is my interpretation - is that Christopher is reflecting this idea that we have a lot of speculation but we simply don't *know* what time is - not really. In my view, this shows the humbleness of science and the idea that we are continually learning over time. Maybe I am interpreting Sujok too positively and they are trying to denigrate science. If that's the case, they are sorely misunderstanding the issue.

    Time cannot be fundamental because it is a "measurement of change" that requires a specific configuration of events before it can be observable. This ironically turns time into an "after-the-fact" type of emergence. For time to be observable (no pun intended), two circumstances must be present: first, you need _something_ that exhibits some type of change, and second, this _something_ must either stop changing, continue changing (like spinning or moving), or demonstrate some other type of change after the first change. This is the *only way* the existence of time can be observably demonstrated (chronicled).

    "Is Time Fundamental?" Time is as fundamental as Flying Spaghetti Monster idolized by Godless losers who hate Accountability... Time does not exist. Time does not move nor change matter but, rather, it is the motion or change of matter that gives the illusion of time. Here is the truth : Neither Space nor Time is a thing... both are just ILLUSIONS being imagined due to observations of matter's changes or motions. Even Einstein once said that time does not exist, not a condition to existence.. The illusion of space, which is actually emptiness, is brought about through observations of the existence of matter, energy, or spirit. It is emptiness or NOTHINGNESS that Matter occupies, not space, and Nothingness is NOT an Existence... Time also does not exist but just an illusion brought about by motion or changes of matter that exists. This motion or changes of matter are being noticed not because of the illusion of time but because of the existence of memory retaining series of perceptions of matter's changes, both being observed simultaneously.. Narrow-minded Materialists, who unreasonably closed their minds to possible existence beyond the physical, have pushed Time as real thing so to show to the gullibles that the beginning is Time, not God... To those stubborn heads who insist that time is a real existence, please bring us "bottles of yesterdays and barrels of tomorrows" to prove it... ... If you can't, then pls stop misleading our innocent children who are our future. We need ACCOUNTABLE leaders to guide this World to the right path for a bright future and NOT down to the dark abyss of no return blaming TIME as all responsible...

Even thre is time in that eternal fundamental Reality then that time is dimensionally diffrent from.. normal time
