This reminds me very much of Stargate Atlantis!

Pudong skyline at night: Whoa! (the photo) ... I forgot my comments while looking for the APOD ed's last name :roll: .

Cheers.

Hi folks, he did not expressly forbid me to post messages; so here goes.
This is a mainstream science board, and it is expressly against the rules to post about alternative concepts here. So don't; thanks.

It's wonderful to see the stars clearly, but your description seems hyperbolic in its nostalgia. Unless you're referring to a night lit by the Moon's reflection of our *own* star's light (or are referring to a rather straight, wide path free of treacherous roots), attempting what you seem to be describing (i.e. navigating a woodland trail by starlight alone) would be a pretty good way to break a limb or worse. Starlight together with airglow provides only something on the order of 2x10^-3 lux, which, on its own, is too little illumination for us (narrow pupil-ed, tapetum lucidum-lacking) humans to see forest paths well. Alternatively, if by "by starlight" you didn't mean using starlight alone to see your way, but just "under the light of the stars", you can still do that.

Additionally, there are still many dark places that were dark half a century ago, and conversely, many places that are brightly lit by artificial illumination now were already brightly lit in 1963.

It is quite a good approximation of what our stargazing ancestors saw, before the invention of street lights

It is Camera Art, not really done for reality, or Astronomy. But a MOOD...

Photography Today, is probably a better venue...
Fine...

The left of the large tower...there is a large boat with a sail....to the left of that is a ROOSTER, the head is just to the left of the boat, looking at the boat...and to the left of that is a BAT...flying into the rooster. There is a GRUMPY GORILLA on the far right, just after the buildings. Pointy head, two eyes, and a mouth with a grimace.

Interesting composite image.

A brief explanation of speculative concepts in science – a proposed hypothesis does not develop out of thin air. Most arise from the piecing together of multiple bits of information, hopeful that a discernible pattern will arise. As more and more data becomes available that fragile premise will be strengthened, or will instead be proven false. When collected data do not fit the asserted idea, then the concept has to be rethought. Repeat, when the available intelligence does not fully agree with the hypothesis, it is the concept that has to be adjusted. Contra indications may in some circumstances indicate the data is wrong, or merely incomplete. The latter poses the greater problem for scientists, even though we have a wealth of data sources from space probes and detectors of various sorts. Sometimes the collected data piles up on computer hard drives so rapidly it cannot be sufficiently examined and evaluated. Then it happens that those persons most intimate with that particular set of collected data do not have the broad view necessary to correlate that information with some adjacent science discipline. For example, a technician may be fascinated by data from his instruments that indicate the temperature of the corona of a star is many times greater than that of the star’s surface, but he does not wonder why. Someone else happening upon that information will be reminded of the temperature variations in the atmosphere of a black hole, and wonder about a common mechanism (and, is dark energy involved?).
So, even though it may be fashionable to ridicule the thinker that comes up with outrageous ideas, a few of those notions will survive and become common knowledge a few years from now. As history has demonstrated over and over. K

"Darken City" illustrates the above view - One plus Two results in or creates a unique third effect. The juxtaposition of two unrelated views stimulates many lines of (your) thought that did not exist until this image was conceived.
My apologies, no criticism was intended :oops:
Perhaps I should have stated that it mildly stimulated a sense of foreboding, among other thoughts, hence the reference to "Life After People".

We liked this image. It would be so nice if folks would learn to turn the lights off at night. Even in our tiny village we are starting to get light pollution as people put up more lights.

Would that this could be so. I miss the dark skies one could easily find half a century ago when you could walk a woodland trail by starlight.

There is a brief description of that in the "Backyard Astronomers Guide". There are photos of the Toronto(I believe) skyline both during and after a power outage. There is quite a difference between the two!

What a magnificent view! Throughout history, artists have often been the ones pushing the rest of us to change, to evolve. I hope we as a species will awaken in time to save the Milky Way from our artificial lights, and restore dark night skies. We will need to change, however, and soon, how we fight light pollution. My views and values on light pollution are different. Thank you Thierry Cohen for your magnificent views of the night most of us will likely never see.

For a very interesting contrast, click on the Pudong link in the first sentence of the description on the APOD page, which is also at the beginning of this page.This will take you to the Wikipedia page for Pudong and a different sort of nighttime photograph. Not quite the same angle, but close.

<<Some focus on the anonymous quote, “be careful what you wish for,” from the tale of The Monkey’s Paw, by W.W. Jacobs, published in 1902, but the use is clearly much older, and probably untraceable. There are similar phrases found in French folk tales, and undoubtedly in other languages and cultures.

In 1874, An author identified as Mrs Day, wrote: Goethe says, “Beware of what you wish for.” (Rough Hewn. Hurst and Blackett, London. 1874. Page 307.) In 1922, James Joyce wrote, in Ulysses, That may be too, Stephen said. There’s a saying of Goethe’s which Mr Magee likes to quote. Beware of what you wish for in youth, because you will get it in middle life. In 1944, Fleming MacLiesh wrote in the Cone of silence’: Goethe said, ‘Beware of what you wish for in youth, lest you achive it in middle age.’ And you agree, and go on still desperately wanting all the things you want now in your yourth. Learn the hard way.

The earliest version I found in Google Books of the exact phrase “Be careful what you wish for” is from a 1891 edition of the Atlantic Monthly. “Be careful what you wish for in this world, for if you wish hard enough you are sure to get it. I once heard a very wise many say this, and the longer I live the more firmly I believe it to be true.” -A Native of Winby, Sarah Orne Jewett, The Atlantic monthly, Volume 67. 1891. Jewett [had] used the quote [previously] in 1883. “be careful what you wish for, because if you wish hard enough you are pretty sure to get it.” -Betty Leicester’s English Christmas, by Sarah Orne Jewett, in St. Nicholas: a monthly magazine for boys and girls, Volume 23, Part 1. 1883

In 1900, Gale and Buss Newcomb used the quote “Be careful what you wish for,” in the story Someone to Crawl Back to.

In 1937, there was: “Be careful what you wish for because you are liable to get it,” she thought with a delicious anticipatory shudder. - From these beginnings, 1937, by Jane Annixter. page 173.

C. Joseph Touhill, Gregory Touhill and Thomas O’Riordan, like many others, attribute the quote to a Chinese proverb: “Be careful what you wish for, lest it come true.” The origin of this famous quote is fuzzy and frequently attributed to an old Chinese proverb, but most people agree that it sums up an important lesson in life. - Commericalization of innovative technologies: bringing good ideas to the marketplace, 2008. In a 1958 textbook for elementary school reading, Paul Paul Andrew Witty asked: Why did the author quote the Chinese proverb: “Be careful what you wish for; you are apt to get it”? - Reading roundup, Volume 1‎ – Page 45

I have not yet seen any actual Chinese proverb that use this quote. A search of Google Books before 1950 does not find a single instance of the quote being attributed to a Chinese proverb. The more common reference is to Goethe, to unidentified wise men, or the common advice of mothers or grandmothers to young children. Google books does not attribute the quote to a Chinese proverb again until 1975, in Deathbird stories: a Pantheon of modern gods By Harlan Ellison. The quote would be attributed to a Chinese proverb 14 times in the 1980s, 67 times in the 1990s, and 306 times in the past decade, according to a June 13, 2010 text search on Google Books.>>
