The Dawn Era Calendar
You might have noticed here and there that I sometimes use a strange kind of dates. Actually, it's a calendar I've invented and named "The Dawn Era Calendar". During these late years, I decided to progressively switch to this calendar, as a particular type of hack, centered on spacetime perception. This article will give you all the details about it, so that you'll be able to use it too, if you feel like it. But before diving into the technical explanations (that you got on the second page), allow me to tell you one thing about the universe, because it is all about it, and us...
About the Nature of "the Universe"
When I - or anyone else - use the word "universe", I guess most people on the planet would think that I'm referring to the "space" outside the limits of Earth's atmosphere. For some people it may be the place where the Gods are living and where you can find Heaven, but I'd say that for the vast majority of human beings, it merely designates that "space", in which the stars are shining. If you have some basic knowledge in astronomy, you will know that beyond the limits of Earth, you first find the Moon, its satellite orbiting around it, then a big void between Earth and the Sun, and somewhere in between (or on the other side of the Sun), two little other balls circling our star (Venus and Mercury), well in brief our solar system with all the other planets, Mars, Jupiter, Saturn, etc... Now, first question, have you ever thought about how it would look like if you'd be - and I mean you in person, let's say inside a spaceship, looking through the (solar-)windshields - far enough from the Sun to be able to see all the system in a single panoramic view? Or, in other words, what do you think you might actually see with your eyes only? Well, let me try to give you the correct answer: you'll see the Sun shining brightly, and... period. Maybe, and I mean maybe, you'll be able to see some orange star-like dot at the location of Jupiter, and yet...
Now, if you'd get close enough to any planet to see it as the Earth seen from the Moon for example, you would be too far from the others to see them with your bare eyes, well... except for what you can see of Venus or Jupiter with you own eyes from the surface of Earth, for example.
So, let's continue the journey, and we first find ourselves into what is called the 'Local Bubble', an imaginary sphere of about 20 to 30 light-years in which are gathered our closest neighbouring star systems. That 'bubble' is included in a more complicated (three folded) structure made of nebulae gases and that kind of things - containing thousands of star systems - inside the 'Local Arm' of the Milky Way galaxy, which is one of the 3 or 4 spiraling arms forming one gigantic disc about 150,000 light-years wide, our Sun orbiting somewhere around 27,000 light-years from the galaxy's center, now renowned to be a giant black hole. Beyond the Milky Way, we find a cluster of galaxies called the 'Local Cluster' (wow... cosmic...) and beyond that, a guess maybe...? Well, more galaxies. And that's it, dude. Anywhere you would look upon, you would see more and more galaxies, separated by inter-galactic space.
If you happen to be well informed in astronomy, in particular about the latest discoveries about the structure of the universe, you probably know that all these galaxies are architectured in a very specific way. Actually, they are not scattered at pure random; they are distributed on some kind of (more than) gigantic invisible cosmic web of which you can find a neat picture of here: Mass Repartition (this kind of picture is based on WMAP Sky Maps). You can also have a look at the videos I talked about in the article "Playing with the NHA Logo: The Tri-Trendao", where you will see beautiful 3D animations of thousands of galaxies seen at this "universal" scale. And as George Smoot points out at one moment in one of these vids, if you would be "there" in person, you wouldn't be able to see what you see on these 3D animations, because of the scale of those things. You would have to travel much much faster than light itself and things would appear to be completely different at that (very hypothetical) speed. Besides, those animations, as most of astronomical pictures and animations, are treated by computers to add artificial colors in order to visualise things which are actually there, but that your eyes wouldn't be able to see. In the case of galaxies networks, for example, white color is used to represent what is called 'Dark Matter', which is what this gigantic cosmic web is made of, and around which usual matter (meaning essentially galaxies, stars and gases) gathers, pulled by dark matter's gravity (and then by regular matter's one too).
Now, the question that I'd like you to ask yourselves is this: do those "reconstructed" representations appear to you as more or less close to reality than what you would see with your eyes? Or you could also wonder about this: do our human eyes - even supported by telescopes to look farther - are the proper tool to observe the universe?
We now know that only 5% of what the universe is composed of - what we call 'regular matter' (stars, gases, planets, ...) - interacts with light so that we can see it. The rest, dark energy (about 75%) and dark matter (about 20%) don't interact with light, and so we can't see it and therefore we have no clue about what they could actually look like. These heavily computerized reconstructions are our only means to get some visual awareness of these otherwise invisible things and then have a chance to better understand their nature. So, yeah, common sense could easily conclude that these reconstructions don't represent the universe's reality properly, but neither do our eyes, and they can only show us 5% of the universe's content.
So, the first point is this, our eyes - on their own - will never tell us anything about the other 95% of the universe, because these 95% don't interact with light, therefore our eyes alone cannot be the proper tool to observe and fully understand the universe (and its nature). We need something else, and this something else is "our mind", but I'm gonna get back to that later on.
Because, in order to really grasp the very sense of this calendar, we need to dig deeper than that. Cause the problem, you see... is all about light; or rather, its speed.
A lot of you - I guess - have already seen pictures of our Milky Way galaxy, and not only pictures, but now things that start to look like "maps". And what I mean by that is: accurate representations of the position of each of all the stars we can observe in our galaxy in a 3D referential respecting distance scales.
Let's imagine we would want to draw such a map (granted that we got all the shiny telescopes we need), we point the telescope towards a star, we calculate its distance from our Sun, we measure its vertical distance with the galactic plane, its distance from the galactic center, etc... whatever. We place this star accordingly into our 3D referential, and we skip to the next one. If the people who are drawing these "maps" are doing like this, they are not making maps of "the Milky Way as it is today", but of something that doesn't exist at all, and which is the collection of all the locations of the galaxy's stars where they were at the time the light coming from them was emitted, and each of them being at complete different distance from us, this length of time is not constant between one and the other. And even if the galaxy was turning in a totally homogeneous way (say, like an LP record), which is not the case (1), that wouldn't be sufficient to guarantee that relative positions between stars are conserved (because we're observing them from inside the galaxy itself).
So, in any case, what I would call the "minimally proper mapping of a star in our galaxy" would:
But now the question arising is: where do we put the Sun relatively to that star? At the position it would be after that same length of time, but calculated accordingly to its own speed and original location at the moment of observation? Yeah? But how are you going to do that with the hundred of millions of stars, each of them being at different distances from us (so different lengths of time)? Which star should be declared as The (temporal) reference? How do you draw the map of the present state when all you got is a dynamic succession of different rotating pasts scatterred across a 150,000 light-years period of time? Well, I'm not sure...
What I do know, is that the galactic map of "what we see from here" is fundamentally flawed and will never help us for sailing into interstellar space, because distant stars won't never be where we see them. And whatever the method that'll be used, the eventual correct map of the galaxy will require to take into account several factors including the speed of light, distance of stars from observation point (a spacetime distance), stars' orbiting speeds (around the galactic center), and so on. So once again, the correct map is not made of "what we see when we look at the galaxy" but of "what we see + lots of very complicated calculations", calculations that are the product of our minds.
* * *
In order to conclude about all this, let's plunge the sword all the way to the brim. Finally, if you think about it, the only place (that we know of) where the universe can be "seen" as it is (more exactly as close to what it is as currently possible), rigged of all the attributes we know about it - and not only as what light shows us - is our minds. It is there and there only, in our imagination, and in these minds' extensions we use to call "computers" that a fully featured "vision" of the universe can be built. So, in practice, what we use to designate by the term "universe" is mostly the mental vision we have of it. Or to be more accurate, the most largely shared vision of it.
Nowadays, the most largely shared vision of it is a mix of the original Big Bang model enriched by the WMAP & Planck satellites' observations of its residual background emissions (and their consequences on the equations), the marvelous pictures of deep space made by the Hubble telescope, the knowledge we have of quantum physics, and what you can see in the videos I talked about, that is to say the kind of "mapping" resulting from the Red Shift Surveys. Besides, to a certain extent, especially for the layman and public masses (but history has shown that great scientists and astronomers have often been influenced by it), the culture of science-fiction whether in literature or in cinema, can also contribute to that mental vision we share of the universe.
And here we are, my fellow dudes, right at the core reason behind the Dawn Era Calendar... And let me rephrase it a little bit, pushing it to its full extent: the only place, in the universe as we know it, where the universe can be seen as closely to what-it-is-now as possible, is - to our current knowledge - the very minds of human beings supported by their electronic extensions (without forgetting that "what-it-is-now" requires extrapolative calculations from what we get - which is actually "what-it-was" due to light speed).
Two consistently fundamental considerations can be drawn from that (although this article is not the place to develop on them):
Okay, now let's see more precisely why I chose the origins of the Big Bang model as the origin of this calendar. On the next page...
