Moon Shadow

Here Comes the Darken Sun,
But Let’s Just Say, It’s Alright

So the great solar eclipse of 2017 is coming to America and we, for ones, are only too glad about it. What, with all that’s going on, the thought of spending time with such a fascinating cosmic event surely beats most of everything one’s been watching on the news lately.
By now, however, every media, the Internet, your close friends, and even your deranged uncle Bob, have already told you all that is to know about it, maybe more. So here’s just a few historical and/or interesting pics to entice and inform you. Call it your personal mini visual tour.
Hover over the photos and click on them and on the links, for data and stories. Eclipses have been teaching us since time immemorial, and while many feared that the sun, or the moon, wouldn’t survive the penumbra, others like Edmond Halley, were open to learn. The one in 1919, for instance, proved Einstein’s Theory of Relativity.

The one visible in 1966 at the bottom of South America led NASA to launch 12 rockets from a beach some 30 miles from where a little boy risked losing his eyesight to watch it through a photo negative strip. Luckily, that pair of eyes survived to experience many others since.

All ancient civilizations studied and documented cosmic phenomena. Comets and meteors, supernovas and moon eclipses, all had tremendous impact on our history on this planet. But things heat up considerably whenever the sun is concerned, and when the day turns into night, well, that’s not to be ever taken lightly.

We gaze, therefore we are. To many of us, this may be our very last solar eclipse, so we’d better make it good, just in case. Choose well your eye wear, pick a good spot, and make up a decent excuse to be there. Gee, the way things are going, the sun coming back after just a few hours may be the best news we may be getting for a while.

Earth Cavities

Worlds Inside, Real & Imagined,
Offer Insights Into Human Psyche

‘Why may we not suppose four ninths of our globe to be cavity?’ Edmond Halley’s 1692 Hollow Earth theory was rightly debunked for its faulty science. But it did lend, at least for a while, credence to a recurrent feature in ancient mythology, folklore, and legends.
No pun intended but underneath it all, he too was drawn to the allure of tunnels, caves, and the underground. The hidden and the obscure are innate to our psyche and beliefs, just as natural or manufactured burrows, are ideal temples for practical and mystical needs.
‘Descend, bold traveller, into the crater of the jökull of Snæfell, (…) to attain the centre of the earth. I did it. Arne Saknussemm.’ Two centuries after the Isaac Newton collaborator made famous by a comet had given up on his idea, Jules Verne concocted his own atemporal version of the enduring myth, in the best-selling novel, Journey to the Center of the Earth.
Halley, an accomplished scientist thought to have been instrumental for the 1687 publishing of the Philosophiæ Naturalis Principia Mathematica, was ironically betrayed by what’s deemed a flaw of the revolutionary treatise: Newton’s erroneous attribution for the mass of the Moon.
By overweighting that mass in relation to Earth, by a factor of 1 to 26, instead of 1:81, the man responsible to our understanding of gravity laws unwittingly gave room to Halley’s supposition: Earth should be hollow, possibly inhabited. And the source of the Aurora Borealis, too.
None of this is detrimental to the two genius of science, or our debt to them. But Halley’s hypothesis did hit a resonant note, if not for its sacred past, then for a long string of mentally ill visionaries and phony prophets, way back from the Enlightenment to, sadly, our days.
BELOW THE BOTTOM
Even before antiquity, caverns were considered places of power, dwelling of spirits of good and evil, passages to other worlds. Many peoples and tribes, some whose descendants still walk among us, believed that the’d come from the Earth’s insides, and were supposed to return there someday.
All civilizations had some reference to the underworld, the Hades, the place where the dead lived. Dante Alighieri placed the Christian hell under our feet, so the faithful would live in fear and don’t stray. Throughout history, burials may have been so popular presumably for reasons other than just recycling.
Even today, some believe that UFOs actually come from beneath us. And just like vampires, fly out at night from hidden entrances in the poles. But the fact is, even if it were scientifically possible for this rock to have a giant hole inside, without cracking, it wouldn’t be big enough to accommodate all theories about it.
SECLUDED CATHEDRALS
To be sure, nature is not shy of keeping us away from its secrets, and often land or underwater caves are as inaccessible to most humans as the outer space is. Vietnam’s Hang Son Doong, the world’s largest cave, has its own jungle, rivers, and climate. And lethal challenges and a roll call of dead people too.
Its exploration is beyond most people’s athleticism and endurance. Just like astronauts are a special breed, so are cave enthusiasts. Also, due to Earth’s volatile geological and seismic configuration, while there may be even bigger caves yet to be discovered, some may suddenly cave in or shape up overnight.
Just as their enclosed universe will remain intimate and challenging, so will one’s connexion with those places. They may serve as a meditation sanctuary or a spot to hide, and the strength of one’s (more)

The Heavenly & the Disturbing

Venus’s Last Trip Across the Sun (in a
Century) & the Annual Dead Duck Day

It’s not unusual for two scientifically relevant events to happen in the same day. But while the transit of Venus in front of the Sun is the rarest of the two, the anniversary of Dead Duck Day packs a surprisingly, chock-full-of-meanings punch.
Venus won’t be seen in this neck of the Solar System before everybody alive today, and probably their immediate children, will be long dead. But what happened to a dead duck, 17 years ago, has became the holy grail to a whole branch of animal behavior research.
Beyond sharing the same date, though, these events have little else in common. But as astronomers and biologists expect to learn a bit more about the orbits of heavenly bodies and the life of mallard ducks, we should all benefit from their insights.
Before we too learn something about what’s happening today in the sky, where thousands will be tracking the rendezvous of Venus with the Sun, and at least in the Netherlands, where those fateful ducks met, a few words of caution.
First, about the Sun. The tragic Greek hero Icarus perished because his feather and wax wings melted as he flew too close to it. Well, for us, flightless mortals, we can’t even look at the Sun. So protect your eyes if Continue reading →
