Blindposted from the present - a long story.

If that were the case, why is it not true for a setting sun? Does the earth move around the sun fast enough that during the time of a sunset it would affect the angle that the sun sets??? If not then the sun is static in the night(/day) sky and should be moving at the same angle as everything else up there... right??? (eta: I'm probably not getting something)
The earth is the center of the universe. It is motionless.

The entire universe revolves around the earth. The fixed stars, of course, revolve around it the same way every time. There is a train track that runs around the earth, roughly above the equator, but at a 22.5 degree angle to it. It is attached to the universe, not the earth. So, that track also moves with the fixed stars. If you happen to be near the equator and see the track, don't touch it. It's moving at a thousand miles an hour and will give you a smackdown.

The sun is a 93 million mile high candle, carried by a train that runs on that track (which itself is moving around the earth with the fixed stars). The train that carries it runs around the (moving) track once a year. 365 days in the year, 360 degrees in a circle, close enough. So, the sun seems to lag behind the stars by a degree a day - the same amount that the train has moved. But because the track is tilted, the sun also moves "up" and "down" (North and South) depending on where the train is on the track. It covers about 45 degrees of north-southness in half a year, and then comes back.

In one day (one 180th of a half-year) the sun moves (warning - linear approximation of a sine wave) one 180-th of 45 degrees, or about a quarter of a degree.

So, not much. But since the sun actually does change position (north to south) throughout the year, it will also change descent angle throughout the year, because the angle made by the fixed stars against the horizon depends on where on the horizon (wrt west) the stars are setting, since they move in a circle around the earth, not in a straight line.

Ok I've just solved it!!!!
They live in a world with more than one sun! This is why they have walked for so many days and had no sunset. Until this night when they have hit a night with all the other extra sun's below the horizon and then the final visible one setting allowing it to finally go dark. All the previous sunsets were hidden by the extra suns in the sky.
Also this also solves the big running question of why the sea is acting strange and rising far beyond normal. It is just because of the solar alignment that happens to be pulling the sea up more than normal!

It reminds me of a short story (by someone, I don't remember who), in which this event (a darkness in a multi-star system) occurred, regularly, but with enough spacing that it threw the whole world in to chaos. Let's hope we don't find hoards of villagers chasing astronomers down the mountain in the next few newpix.

This question's been answered, but for extra points who's read Flying Sorcerers by David Gerrold and Larry Niven?

Spoiler:
Zorin_75's results say "158 arcsec/pixel" over an image size of 1024 x 682. At 3600" per degree, that's about 23 pixels / degree. If Zorin used the full width of the original frame (553px), that converts to 292 arcsec/pixel, or about 12 pixels / degree. But the sun circles I was drawing yesterday, which I thought were a little undersized, run from 21 to 23 pixels, making the sun about four times its proper size. (If Zorin's submission was an enlargement of only part of the original width, the discrepancy gets even worse.)
Does this mean their sun is too big? Has earth moved closer, or has the sun enlarged? Can somebody with more of a clue than me check the sun's size against Sagittarius? (Or the moon's, since they're the nearly the same?)

That might be another explanation for the enormous tide.

Which begs the question, what planet are they on that they have the same constellations?

I had to think about this a little while. If the sun is enlarging, tides won't be affected (except by changes to sea level due to changing temperature). If they're currently moving closer to the sun, there's going to be more to attract their attention than rising seas. ("Holy mustard, it's hot! And where did the moon go?") If they've moved closer to the sun long ago, they should be used to the altered tides.

A shifted moon would be a better explanation. A relatively small shrinkage [ETA: Wrong!] of the moon's orbit would make the moon geostationary, which would cause a permanent high tide at two points on earth.

As for your second question: From anywhere in the solar system, parallax would be slight enough that to the unaided eye constellations would look pretty much unchanged.

I have; it was fun trying to decide which gods (or wives) corresponded to which F&SF writers. It's getting Randamned hard to find a copy.

ETA: Clerk of the Newpage! I decree that you write posts that I'll be able to read when I get up in the mornip (which generally happens at least a newpix before I actually wake up). If you want to mention a good F&SF book that hasn't already come up, that's a bonus.

Huh? Geostationary orbit is 25,000 miles up. The moon is 250,000 miles up. I guess the difference is just a zero. Really, nothing at all! :)

That was, quite possibly, one of the most entertaining ketchups I have had. I found it all incredibly exciting and informative. Once again, I am blown away by the brilliance that surrounds me here (and not without a fair amount of envy). I have nothing to add, really, other than to say that the analysis was terribly fun! :mrgreen:

Oh, but I do have a question. All the analysis seemed to be based on the assumption that we, as observers, are facing due West, correct? Would it make a difference if we were, in fact, facing Northwest or West by Northwest?

Oops; years ago some friends and I looked at this, and I think my memory has slipped a cog. Geostationary for the moon would be higher than for a comsat, because, unlike man-made satellites, the moon has a significant fraction of the earth's mass, requiring a real two-body calculation. But it wouldn't be nearly as far out as the moon's current orbit; you're right. My bad.

Actually, I've been meaning to submit moving the moon to geosynch orbit as a What-If? question. All sorts of fun results: The earth becomes more egg-shaped (earthquakes and lava), we get two permanent high tides (much flooding), one hemisphere's lovers have ten times the moonlight while the other hemisphere's lovers have no moon at all, most of the regular geosynch comsats fall out of orbit─and lunar eclipses become much more common (and much longer).

A nearly geostationary moon would be even more fun, as the effects gradually creep across the globe, perhaps at the rate of a few miles a day.

Technically, it's a plot of angles against radial distance from an origin (theta by r); I've read that matplotlib won't even allow negative values for r. Less stuffily, it's any plot that can be made to turn in a circle and bite its own tail. That's what I'll be doing (if it works): plotting post activity on a 24-hour clock dial, midnight to midnight.

Actually, it's kind of necessary for the sun to be setting (and therefore, because the sun set near the horizontal center of the frame, for the camera to be facing) south of west. That's because it must be around November for the sun to be in or near the constellation Scorpius, and in November the sun sets south of west, viewed from anywhere on earth except parts of the arctic and antarctic where it doesn't set at all.

Ooooh, clever! Also, seems to me that negative values for r wouldn't make much sense on a clock - rather, should be displacement from some "normal" value of r.

Well I did some calculations on two stars that have moved quite a bit.
Image
η Ser and ε Sco, the first one, I marked twice, not realising it was a star that had moved.
Using their proper motion, and their approximate distance in the sky (measured using Stellarium), I got 14,300 years for η Ser, and 12,900 for ε Sco, both in the future, which would be consistent with Antares going supernova, and is now only very faint. :D

If it's 13000 years hence that's half a precession cycle so the sun will be around Scorpius near the end of northern spring/start of summer.

η Ser and ε Sco, the first one, I marked twice, not realising it was a star that had moved.

Using their proper motion, and their approximate distance in the sky (measured using Stellarium), I got 14,300 years for η Ser, and 12,900 for ε Sco, both in the future, which would be consistent with Antares going supernova, and is now only very faint. :D


Hmm, that's just about half a cycle of axial precession, which changes things. It would make it May instead of November, so looking north of west instead of south of west. (Ninja'd!)

But... what about the stars that have not noticeably moved? Can you check whether they would be expected to have little or no movement over the same time period?

I just realised something. Stellarium has the proper motion data, so if you put in a year around 15500, then the stars will move to the right place! :D

I edited a couple pages on the wiki, in case anyone's interested to know. Tarot cards and newpixbot. Tarot cards is wanting of some actual tarot cards as of now ;)

Those wouldn't be the two smaller ones, by any chance?
Even if they would, the edit was only 7 minutesH later, and 40 views is perhaps a bit too much...
The only other thing I can note is that the two small ones are displayed in a different way (caption instead of a tooltip). But why that is (size?) or whether that could make a difference in view count, no idea.

Browsers are complicated beasts nowadays. Maybe one of the common browsers will prefetch at most N hidden images on a page, and there are N-2 other spoilered images upstream of your post on the same page? Or something of that nature.

"There is a theory which states that if ever anyone discovers exactly how a browser operates, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory, which states that this has already happened."

There may also be caching of the image files by various components - your ISP, the proxy servers of the hosting service - the counting code will not be told about requests fulfilled by these devices.

If your right, we're going to have fun getting a latitude, or even a date(not that that matters anymore): procession - 1 degree every 70 years. IF spring equinox has progressed ~200 degrees, is it still on March 21st?

I'm getting a solar position of 14h 55m. Assuming we are still in the Age of Aquarius,putting the date at Nov 8th (w error of about a day)

other useful details:
I measure 7.9845 pixels/degree
the stars moved 190.55970193 pixels in 15 newpix (sqrt(36313)pixels)
there are 6.36 minutes of Time between Newpices

Depending on how clean the water is it might be a good idea to clean Megan's wound here before they move on. Who knows how unsanitary the moleopard's claws might have been prior to the attack.

I think she fell on something; wasn't clawed by the Leo.

Thank you! I've been waiting for someone with skills to do this. This makes my brain hurt way less so, again, thank you. Awesome job. :D

ggh had added some tarot cards to the wiki, then removed them without explanation. I readded them. There's still a lot of work to be done, however.

and it is extraordinary hubris to presume that any calendar will be in use for more than 1000 years, so I am avoiding the names of months and choose to specify time of year by the seasons

If it's 13000 years hence that's half a precession cycle so the sun will be around Scorpius near the end of northern spring/start of summer.


For the non-astronomically-informed, what's a precession cycle?


The earth's axis moves relative to the rest of the sky, very slowly. It remains at the same 23-degree angle with respect to the plane of its orbit, but it wobbles so that the axis traces out the walls of a cone. It takes 26,000 years for the axis to precess (wobble) all the way around the cone back to where it started.

To imagine the effect of half a cycle, imagine that it is the winter solstice in the northern hemisphere, where the north pole points most toward the sun and sun is "in" (that is, appears juxtaposed with when looking from earth) the constellation Sagittarius. Directly opposite the sun (that is, in the exact opposite direction from earth) is the constellation Gemini, which is therefore visible in the night sky all night from nearly anywhere on earth.

Now, reverse the tilt of the axis, so that the north axis points away from the sun at the same angle that it previously pointed toward it. This makes it the summer solstice instead of the winter solstice in the northern hemisphere. But Gemini is still directly opposite the sun, and the sun is still in Sagittarius. So Gemini is now prominent in the night sky in summer instead of in winter. If we keep the months of the year aligned with the astronomical seasons, then the sun is now in Sagittarius in December instead of in June. In related effects, some constellations such as Sagittarius and Scorpius that were on the southern hemisphere of the star globe, south of the star globe's equator, are now north of it, and so are more prominent in the northern hemisphere's sky for more of the year than before. And the reverse is true for other constellations. The earth's axis is also no longer aligned with Polaris; instead, Polaris is now 47 degrees away from the celestial north pole and traces out a circle with a 47 degree radius instead of being nearly fixed in the sky.

The precession is so slow that only a very long-lived creature that is very interested in time would tend to notice. (A TemporalKraken, perhaps.) However, if I recall correctly, there's at least one Renaissance-era clock that includes a mechanism that rotates once in 26,000 years to track and display the precession.
