"HOW LONG IS NOW"

Recently i was 9 days in Berlin. The hostel where I stayed was on Oranienburger Straße. And in this street i came across an intriguing wall a few times a day. Not the Berlin Wall, but a wall of the former arthouse Tacheles. "How long is now" was written on that great wall. The more I started thinking about this wall saying, the harder it was for me to find an answer in my skull. A true brain teaser.
What is now :?:
If there is one now, how long will it take now :?:
Is there also one now, if I am not aware of that now :?:
Is there 1 now, or more than 1 :?:
How and where does it arise now :?:
Is my now also being someone else now :?:
When someone goes relaxed through life it is sometimes said, "He lives in the now" Even with animals that do not care about tomorrow the same. Through our memory we take the things that we experienced in the present with us into the future. Through our memory it is already a bit tight now, and when we finally arrive, it is now a bit now. Although in a different time frame, but in the past the past still runs its programs in the various brain regions. If I go and get my beloved Dick Swaab then I come to the conclusion that I am never never present at the present. After all, what it makes now (my subconscious mind) is always at least half a second ahead of what I become aware of. I never meet the creator of the now, the viewer (my consciousness) may think that now is now, incidentally, a nice illusion that I think that now too, even if I know that it is not. "Is this later :?: " Harrie Jekkers ( A dutch artist) once sang nicely. Tightly defined blocks of time that make it now into the now I do not believe in, I see those blocks of time that make it now as a kind of intertwined jet stream in my mind.

Fundamentally...

There is Heisenberg's uncertainty principle that makes precision of measurement of time dependent of measurement of energy of the same phenomenon. The moment of time can be as short as we wish if we let energy be indefinite.

However, we can assume any phenomen we know of does not exceed energy of the whole Universe. The mass of the ordinary matter in the observable Universe is about 1.5*10^53 kg. After multiplying it by c^2 (by E = m c^2), we get 1.3*10^70 joules. That would lead to uncertainity of energy of the order of magnitude of 10^-104 seconds.

However, before we reach it, there is Planck scale - a region where quantum and gravity effects become comparable. We don't know what happens there, our experiments don't come close to it and our theories are mere speculations with a lot of beautiful Math.

Planck time is 5.39 * 10^−44 s. The Universe may have completely different structure in this timescale.

I remember reading the smallest discernible time difference between two stimuli is 3 ms for a human brain.

But really, it's a functional thing - "now" is there for dependent on the context it's used in and describes the time frame between the last event that mattered in this context and the next one.

Thanks for the Heisenberg link Magz.

I am diagnosed as a very slow-thinker. When i see the quote "How long is now" in a way my conscious experience the world in my head and the world outside my head, than my moment of NOW takes longer in a psychological way. Or am i talking crap now :?: :wink: :roll: :lol: 8)

Time stands still. time is currently timeless

Einstein may not have intended it that way, with his 'relativity', but there are cases / situations that time progresses while time still stands still. This standing still of time can be spiritual, but it can also stand still in a mechanical way. :wink: (see below)

What if 'Now' is relative and it lasts as long as we each say? That would go along with therapy and the way PTSD individuals react to certain situations as if then were now. In their cases, Now seems to be a transient state. Now is then, until something happens to make then Now.

Well...

There is the "now" as in "right now I am fooling around posting on a website when I should be doing housework".

And then there is "now" as in "the GOP controls the Senate now, but the Dems now control the House".

And then there is "now the Atlantic Ocean is getting wider and Europe and American are moving apart, and the only dinosaurs around now are birds, and flowered plants now dominate flora on land".

The first "now" is measured in seconds, the second in years , the last is talking about the last 63 million years as being "now". :lol:

But they are all correct usages of the word "now".

Let's Put it This Way as simple as i Will, Now;

Heaven is a Place With No "Time";

Hell is a Place with All "Time";

It's Relatively Impossible to Fully Understand This, Unless You Visit Both Totally Different Perceptions Now;
And No Two Experiences Will Be anymore Identical than a Snow Flake or A Finger Print Now For Real too, Now.

The First place is so, so much Better Now; You Will Live Forever Now And Never Literally Be Any Thing Less
Than Content Now; Even if You are Dancing a Metaphorical Tight Rope in Effortless Flow, too as all becomes 'Hope/Love'.

This is Nothing New Now; Described in 'Sacred Texts' with so many Metaphors since Humans Lost their way in past and future illusions up to and including Forever Time Hell Now; where a Second May Be Perceived as A Thousand Years of No Escaping 'Time'.

But Honestly; it's Pretty useless to Describe this to someone who is rather 'Luke Cool/Warm' and has been to neither place, now.

There's always that isolated Chance; Like a Really Big Camel Passing through the smallest cultural needle eye ever now;
that someone else goes to no time now too forevermorenow; Sort of like an Anti-Raven; an Anti-Poe too; More Like
a 'Jonathan Livingston Seagull' on a 'Wrong Planet', too..:)

"Does time actually exist :?: "

Math is a man-made construction, so in my view math has little or nothing to do with the physical particles in the universe. I view the physical material that clocks and watches are made of as a reality, which are independent of what is meant by the time indication on clocks and watches. Quite a few people look forward to the December month, well, but the December time indication with all its bells and whistles does not exist either. The concept of December is purely a construction that was invented by people. on the bottom right of my laptop it is reported that it is now November 24. All nice and nice, but if I think about it seriously, nonsense, that 24 is a human construction, and the concept of November is the same.
When I say that my world equals 1 second to what most people understand for 1 day, I am outside the reality of those people, but those people are again outside the reality of my reality.

When will people wish each other a happy New Year? They don't do this by the bank in April or August. But why not? If I decide that the new year starts in April or August then the new year also starts in April or August :) For my part 1 year lasts for which the masses need 12 years. Quite strange how my mind is trapped in man-made constructions.

I wish everyone a pleasant 'Tuesday' today :!:
And for the coming night I wish everyone a happy New Year :!:

I've heard people say "I'll be there now, in a minute".

I think that we should give up the whole concept of "time".

And....the sooner we do it the better ! !! !! !! !! !! !! !! ! :evil:

I sometimes have blind spots in my mind (maybe I always suffer from blind spots :wink: ), I may also be looking at a blind spot at the moment. And therefore the question that i ask is maybe a very stupid one, it is not a rhetorical question.

What time is it currently in the middle of the sun :?:

And I do not mean whether it is currently summer, winter, spring or fall there, which I do not think they have seasons there. And I do not mean the time indications in relation to how we interpret time here on earth. I mean the mechanism that makes time in the middle of the sun. What I wonder is whether it is in the middle of the sun like in the middle of a hurricane. In the middle of a hurricane, also called the eye of the hurricane, the wind seems to be quiet, or in any case extremely much less wind than outside that eye of the hurricane.

Youre right. You are asking a dumb question. ( BTW: am not gonna apologize for calling your posts "dumb" because I think that you do better).


The core of the sun is the most violent spot in the solar system. Imagine a hydrogen bomb going off, and then imagine the H bomb being a Roman candle that goes off continuously- for billions of years. That's something like the core of the sun.

I don't know where you got the idea that the core of the sun was in anyway like, or analogous to, the eye of hurricane. It is not. Its not a calm place. Quite the opposite.

Second: because it is violent, and because stuff happens over time (mainly atoms get fused into larger atoms) at the core of the sun, time does not stand still at the core of the sun, any more than it stands still on earth.

The galaxy (the whole milky way galaxy) is built something like a hurricane on earth is built. Sounds like you have the sun and the galaxy confused. The Galaxy doesn't have an "eye" but there is a giant black hole there.

Thank you for your response to my dumb question. If it is really a dumb question you could easily have answered it. I don't read an answer to my question in your response. What time is it currently in the middle of the sun :?: Or it must be that you mean that due to the high activity there is a compressed time in the middle of the sun. I mean something like the opening of a balloon where blowing makes a bigger balloon. I have many more stupid questions about the concept of time. And I will place that in one of my next comments. I already know the question, and that is loud.

What is the color of time :?:

Its the same time at the core of the sun as it is here on earth. You haven't given any reason to think that time would run any different there than on the surface of the earth.

If the sun were a black hole then time would stand still on the sun, though it would keep running on the earth.
