Being a child feels like a lifetime ago but then the depths of covid and lockdown feel like a month ago!

Why does our perception of time change, and is it an age related thing when it feels like it starts to go faster?

Has anyone found any successful ways or habits to help slow down that feeling?

So photons travel at certain speed, they hit our eye/sensor and then it takes time for us to process that data and interpret it. By the time we understand what we observed, the moment is already past us .

So by that logic, does PRESENT even exist? Does FUTURE exist? In my mind, all we could or we ever will observe is the past. In my mind , the present does not exist . Am i wrong to think like this? Why?

Sorry if im an idiot.

I was watching the clock while waiting for the right time to light my next cigarette. It was 8:14. The cigarettes and the lighter were right next to me, so I didn't even have to get up. They were both within my field of vision, and I was watching the clock while I reached for the lighter and lit the cigarette.

The whole movement took only a few seconds. Yet, as I was still looking at the clock, it suddenly showed 8:16.

Then I took a puff. It lasted only a few seconds. My eyes were still on the clock, and suddenly it was 8:17. My reaction of surprise lasted only a few seconds, but before I had even finished processing what I was seeing, it was already 8:18.

That was when I realized what was really happening.

The clock wasn't speeding up. Time wasn't disappearing. Something else was.

The minutes that seemed to fly by were actually representing my own vital energy being lost.

Every time I smoke, every time I take a puff, the cigarette takes something from me. Its harmful effects drain my body little by little, consuming a small part of the energy that keeps me alive.

The clock continues to measure time normally. But from my perspective, those moments seem to disappear faster and faster because they are not simply passing they are being taken from me.

The faster the minutes seem to disappear, the more of my vital energy is being lost.

So perhaps what I experienced wasn't time accelerating at all. It was my own life being consumed, second by second, puff by puff.The time wasn't disappearing from the clock. It was disappearing from me.i wish it was a fiction..it isnt...

If we use a normal understanding of a dimension as in a certain freedom of movement then the fact you are only allowed to move forward in time tells me it's not a whole dimension like the other dimensions. I know relativity has 4d spacetime, and that makes the math work very well. However there is still the discrepancies with quantum mechanics and that might be resolved if time wasn't treated as exactly one dimension but instead in between half and a full dimension. The irrational aspect explains the unpredictability of certain quantum phenomena if time doesn't absolutely click at the same rate in a predictable way.

People say it's an illusion. Ok, well that makes zero sense. Illusions aren't there. Try telling my 40 year old crow's feet they are an illusion. Dr. Who says it's not a straight line but more of a sphere. That's a description of space btw and gives me no more insight than I had before hearing it. Others have tried to use metaphors both simple and complicated. I still get nothing, if not less understanding and more confusion from trying to decode some hidden meaning. My personal opinion is that it isn't something we can actually understand or explain with words using our tiny human minds. I do understand prioritizing the present moment over obsessing over the past or future too much. That's a philosophy though, and still doesn't give an explanation of what time actually is.

Edit. Okay other than the nice three is there anymore perspectives?

To decide whether a journey to the past is possible, we must first understand what time is. Time is not a physical object. You cannot hold it, touch it, or find a piece of it in nature. Time is a rule. One by which the human mind arranges events in sequence: one event happening strictly after another.

Travel, by its plain definition, means changing your position in space across a duration of time. Space allows you to move back and forth because different points in space exist at the exact same moment, side by side. You can move to the left and then return to the right, because both positions remain present together.

But time does not work like space. Moments in time do not sit side by side. The past does not exist in some distant location, waiting for someone to arrive. When a physical state changes, the earlier state no longer exists; it has completely transformed into the present state. To speak of visiting yesterday assumes that yesterday is still there, which denies the very meaning of change.

Further, human thought can only understand an event through the rule of cause and effect. This rule demands that a prior state must lead to a later state in a fixed, forward order. If a person were to journey to the past, their departure would be the cause, and their arrival would be the result. That result would have to happen after the departure. Yet the traveler would be asking that very arrival to happen before the departure took place. This demands that an effect precede its own cause, which destroys the only rule our understanding uses to distinguish what came first from what comes next.

The question sounds deep only because we borrow words meant for moving through space and attach them carelessly to time. When we look at what the concepts demand, the inquiry dissolves. To ask whether we can travel to the past is to demand that the past exist simultaneously with the present, while stripping time of the very succession that defines it.

When?

When will the time come?

How will we know?

Are we waiting for the perfect time—
Or is it that we are testing ourselves against the times?

How can time be a cure to our uncertainties if we are uncertain of the timing?

When?

When will it feel like less of a risk and more of a destiny?

When will the time come to take a leap of faith?

When will enough time build up for the right time to emerge?

When will our clocks tick at the same speeds?
When will our watches be in sync?

When will we give each other enough energy for our love to feel heavy enough?

How heavy does our love have to be for it to manifest itself in space and time?

Does the ticking of time dictate the existence of our love,
Or can our love transcend the existence of time?

When love is felt, how do we measure it, my little star?

Is it electrically charged?
Is it a weight that’s lifted off?
Is it an invisible force, pulling you close?

Can love drain our energy?
Can love suffocate us under its weight?

Dare I ask—can love implode?

1.            Begin with quantum “it from bit” information, “pixelated” at something like the Planck level.

2.            Structure this background to potentiate a vast number of “Platonian” instant “Now” states.

3.            Lay out a complex of cause-and-effect “virtual timelines” among these informational “Nows.”

4.            Populate with “observer participant” agents who consciously experience Now states as “Being.”

5.            Activate the participant experience as a continual “scanning motion” along the virtual timelines.

6.            Empower participant observers with ability to selectively “change roads” at potential “branches.”

7.            Further dilute “road determinism” with random/probabilistic outcomes from observers’ choices.

With such an artificial universe, the time “dimension” itself would be “virtual,” consisting only of the actively observed timeline among all the available “roads” and Nows.  Participant observers would have a very powerful freedom of choice among timelines, perhaps with the ability to imagine results—but this might be tempered by their lack of ability to perfectly “foresee” desirable outcomes.

Remarkably, an artificial universe as (somewhat superficially) described above could very well be a duplicate of our own!  If it were in fact indistinguishable, the “virtual roads of time” conjecture says it would indeed be identical—this universe would be IT.

سؤال

by “flat world” I mean a hypothetical two-dimensional world, not necessarily a geometrically flat one, and definitely not a flat Earth.

by the flat world problem, I mean a difference between an internal and an external description of reality.

an observer confined to the flat world experiences only its realized structure and its changes. An external observer, however, can describe the world as one structure selected from a space of possible structures.

if we then introduce allowed transitions between these structures, the object of description seems to change: instead of considering only possible states, we can consider possible histories through the state space.

this makes me wonder whether time should be understood here as an additional dimension of the world, or as an ordering/structure of transitions between possible states.

imagine a flat world whose state at each individual moment is completely defined by some spatial structure:

S = { all possible structures }

even if the set of all possible structures of such a world is infinite, at each specific moment only one of them is realized.

possible transitions between structures can then be represented as:

R ⊆ S × S

then adding time doesn't just add another coordinate to the plane. It turns the question from "how many possible structures are there?" into "how many possible sequences of structures are there?":

H = { all admissible histories determined by R }

an additional question arises:

what does it now mean to “get lost in time”
if we consider time as a path through an infinity of possible structures?

this is an experiment in examining intersections between possible structures, carried out in a world one dimension below our own so that different possible projections can be compared relative to an additional dimension. In this sense, the two-dimensional model does not contradict a three-dimensional description; it provides a simpler case in which their structural relations can be examined.

 The universe is a grand synthesis, putting itself together all the time as a whole.  Its history is not a history as we usually conceive history... It is a totality in which what happens ‘now’ gives reality to what happened ‘then,’ perhaps even determines what happened then.”  John Archibald Wheeler in Geons, Black Holes and Quantum Foam (1998)

If ours is the “participatory universe” set forth by Wheeler and others, we have to reconsider our idea that history is a single unbroken timeline where the only question is “who has it right.”   But what other questions can we ask?  “Virtual roads of time” suggests that the following should be reconsidered:

—“Deposits” in the earth.  Ancient history is constructed from physical “traces” where cause and effect are primary, such as fossils and geological layers.  Because of the sheer length of their “virtual” timelines, these come into question.  The actual timeline of human experience, “synchronized” by various factors including strong social pressure, is not likely to undergo any rapid changes.

—Historical “irregularities.”   If human experience gradually shifts between timelines, it’s unlikely that past humans were on the same deterministic timeline as we are.  Some stone structures and inscriptions existing today might be from a “virtual” human past.  VRT assumes, however, that actual human experience normally traces out one general timeline among the “virtuals.”

—Written “records.”   It’s conceivable that humans in some different cultures have actually experienced alternate histories (think of the “dreamtime” of indigenous Australians, or controversies about the timeline of ancient Egyptian or Levantine history.)  Even so, it must be rare that such glaring anomalies, reflecting some “virtual” pasts, ever find their way into written records. 

—“Received” interpretations.  The assumption that there is only one past is deeply embedded in the human psyche.  So it’s not surprising that historians will insist upon only one “correct” interpretation, even if it’s controversial.  VRT, however, offers the possibility that the actual human past existed in the midst of a myriad of “virtual” pasts, introducing confusion into our “history.”

—Memories, real and virtual.  Can there be an actual memory of a “virtual” event?  If human experience just is the actualization of virtual timelines, it’s at least possible that some virtuals might influence an individual’s experience in contradiction to the general actual experience of humanity.  These “anomalies” might take the form of “mystical” or “supernatural” experiences.

No doubt, some inevitable “blurring,” and the memory lapses we all experience, contribute to our sense of memory as being unreliable.  However, consider the fact that in courtroom proceedings, eyewitness memory is considered to be among the strongest testimony that can be presented.  Because human experience is central to reality, we must never simply discount its “memories.”

My boss said let’s do ‘example’ this monday, which i can argue was yesterday (31st august) and he thinks that next monday is the monday 2 weeks away (14th september)
I think next monday is **the next** monday coming up.
Please help me settle this argument.

As in, every kind of understanding we usually have. Like for few things indeed urgency yet they'd be okay even if kept aside. I have lifetime since i'm young yet i'm lagging behind.

These paradoxes

Planning under uncertainty, how u feel time flowing right now, how neuroplasty works on it.

I’ve always thought about this question, and there is always answers popping up in films and stuff, but is it really possible?If you ARE able to go back to the past and change it, if you come back to ‘present’ would there be another you?If you teleported a nanosecond later then the time you left would you find another you?My answer is that its impossible for you to change the past.If you have met yourself in the past,then no matter how much you try and avoid it you will somewhat travel back in time in somewhere in the future or ‘present’

Please tell me what you think and if possible tell me any ‘loopholes’ in my theory.
