My Favorite Maya Mythology and Astronomy

You’ve already been hearing about how the ancient Maya didn’t predict the end of the world today, that’s just misinformation, so I thought I’d share some of my favorite accurate topics about the ancient Maya astronomy and mythology.

Dark Constellations

In western astronomy and western mythology we recognize constellations as dot-to-dot pictures made of stars. In other words, we make images out of “positive space” to use some art terminology. The ancient Maya are a completely different culture: several of their constellations are made of “negative space.” They recognize images in the dark spaces between the stars. Here is an enhanced image, you can easily see the llama across the middle (with a star for an eye), and the snake in the upper right-hand corner:

Andes-Milkyway-compressed

 

I always love to use this as an example of how “different cultures are different.” Just because we think dot-to-dot pictures are the “normal” way to do constellations doesn’t mean every other culture everywhere also thinks that.

Venus

The ancient Maya place extreme significance on the planet Venus. Their calculations of exactly when it will rise, set, first appear after sunset, last appear before sunrise rival even today’s computers. And they didn’t have computers. We should spend more time observing natural phenomena ourselves.

Calendar

Their calendar is AMAZING. It has cycles within cycles. There are several good java converters out there that show you how it works.

Also, when you see a picture of the “Maya Calendar” it should be laid out in a rectangle. If it is in a circle and looks like a compass rose it is most likely the Aztec Calendar. (If it looks like gears cycling within each other, it might be the Maya Calendar after all).

Thanksgiving and Astronomy

Thanksgiving is upon us, here in the United States. By now your in-laws, friends, acquaintances, and family have probably learned that you think Astronomy is cool. Which means you’re the expert. Awesome!

Wait, did that worry you a bit? Being called an expert in astronomy? I sure get worried when I’m called an expert. So, just for you, an astronomy cheat sheet for Thanksgiving dinner-table conversation! So, if you want to steer the conversation away from politics and religion, here are a few ideas – in no particular order.

Topics You May Be Asked About

Water on the Moon

Question: So I hear they discovered water on the Moon! Or, what was that a couple weeks ago about NASA crashing something into the Moon?

Answer: Yup! There have actually been a couple of discoveries recently, but when NASA’s LCROSS mission slammed into a crater at the Moon’s south pole, it kicked up a cloud of material (which is what they were hoping for), and they discovered water and a lot of other interesting molecules in that cloud. Is it enough to use? Yeah, but we’d have to clean out those other chemicals first which might be difficult.

More info about Water on the Moon.

2012

Question: I hear the world is going to end in 2012, what’s up with that?

Answer: No. The 2012 hoax is based on a bunch of misinformation and misinterpretations. The planets won’t be aligned, the poles won’t flip, and neutrinos from the Sun won’t boil the Earth’s interior. Intriguingly, we will have a solar maximum in 2013, so 2012 promises to have some nice sunspots, flares, prominences, and other Sun activity.

More info about 2012.

Mars

Question: These questions have a wide range: from “Is there life on Mars?” to “How are those Mars missions doing anyway?”

Answer: Yes, we’ve found water on Mars, though not a lot. We’ve found that water many times. The most recent surface expeditions to Mars were Phoenix (at one of the poles, currently probably under a layer of ice), Spirit and Opportunity (which both had rovers). Phoenix is now defunct, as there is no sunlight from which it can draw power. Even when the Martian winter recedes and the Sun shows up again in spring don’t expect Phoenix to turn back on. Spirit and Opportunity have been going for almost 6 years now – and their original mission was slated for 90 “sols” (days on Mars). Their 6-year anniversary is January of 2010. At this moment Spirit is stuck in a sand trap, and the NASA JPL techs are working hard to extricate her.

And no, we haven’t found life there yet and the chances are getting slimmer.

More info about water on Mars, life on Mars, Phoenix, and the rovers.

Hey, What’s That?

Question: Hey, what’s that?

Answer: Jupiter.

Well, it is possible that it is Sirius or Mars, but you’d have to be up fairly late with your family for that to be the answer. If you’re out for a post-dinner walk, and you notice something bright in the sky, it is probably Jupiter. To double-check yourself, Jupiter is low in the southwestern sky before sunset here in the United States.

More info on what’s in tonight’s sky.

CERN

Question: I hear they turned on that world-destroying black hole maker again.

Answer: Yup! I mean, no … it isn’t a world-destroying black hole maker, but they (CERN) did turn on the “LHC” (Large Hadron Supercollider) in Switzerland. They’ve turned it on, spun it up, and even gotten collisions of particles! Yay! Now, it will still be a bit until they discover that strange particle they’re looking for. And maybe a little longer until they prove that dark matter is real.

By the way, did you know that CERN stands for European Organization for Nuclear Research? How does that make sense? (Well, okay, I get the “RN” instead of “NR” part, but … I don’t get the “CE” instead of “EO”)

More info on CERN.

Topics You Might Like to Bring Up

Free Spirit

Pitch: We have a remote-control car stuck in a sand trap on Mars.

Details: Well, it’s actually a lot cooler, more difficult, and more emotionally wrought for many folks than just a remote control car and a sand trap. Spirit, one of our two rovers on Mars has gotten hung up in some soft soil. It has been trapped for weeks – the soil is softer than they expected, and there may be some loose rocks hidden by the sand which make plotting a course almost impossible. Every movement is like sinking into quicksand – it causes the rover to slip deeper into the soil. Also, there are some indents on the bottom of the rover that could easily get hung up on some sharp rocks underneath Spirit’s belly if the rover sinks too far. The rescue operation is continuing.

More information on Free Spirit.

Galileoscope

Pitch: The only decent cheap telescope on the market.

Details: For the International Year of Astronomy a working group was put together to design a cheap, decent telescope kit, that any kid could use to see the rings of Saturn. This telescope is amazing for the price – and you get to learn how the optics work while putting it together. It also only takes about 10 minutes to assemble and no tools are required. This is a good beginner scope, but you should complement it with a tripod to get any use out of it at all. I highly recommend the give-one-get-one option, because they’ll send Galileoscopes to kids in underserved countries with these donations.

More information on the Galileoscope.

Shuttle Missions

Okay, watch out because this one could turn into a political conversation.

Pitch: There are only 5 shuttle missions left until the Space Shuttles are all retired.

Details: It’s about time we created a new ground-to-orbit technology. The Shuttles were launched in the 80’s (raise your hand if you’re still driving a car that was built in the 80’s. I thought so – not that many of you). Besides, if your clunker breaks down you’re stuck on the highway and you call AAA for a tow. If your shuttle breaks down … well, we’ve seen that twice and it is heartbreaking. I remember both vividly, and I’m actually just barely old enough to be able to remember the first one.

More info on the shuttle retirement, and the replacement.

Enceladus

Pitch: Yowsers watch out for those geysers!

Details: Cassini, which has been in orbit of Saturn for some years now, has just done a couple of screamingly-close flybys of Saturn’s moon Enceladus. Why do you care? Because Enceladus is on the short list of places in our solar system we rate as likely for finding life. In fact, one scientist has ranked it as “more habitable” than Earth, based on a set of seemingly-reasonable characteristics.  You also care because, well, why are there geysers on this moon? What are they made of? What do they mean? We don’t know all those answers yet, but Cassini will help us figure it out.

More images from Enceladus.

My favorite (click and look closely at the dark side …):

One of Cassini's images of geysers on Enceladus.

I wish you a wonderful Thanksgiving, if you celebrate it, and a wonderful Thursday, Friday, and weekend if you don’t.

2012 – The (2009) Movie

Um. Um. Um. Um. Where do I begin?

The movie was entirely preposterous. There almost wasn’t enough science to make fun of! It ranks way above Sunshine in my ranking of action flicks full of terrible science, and yet it barely holds a candle to Armageddon. Perhaps no one can top Armageddon as the best movie to show an intro Astronomy class: the best movie to ask Astronomy students to rip to shreds.

I think we (the astronomy educators of the world) were worried about nothing. If this movie convinces anyone that the 2012 hoax is real, then they weren’t watching the movie.

In any case, here goes!

==SPOILER ALERT 1==

NO REALLY! STOP READING NOW!

Science: F (A=perfect, F=utter failure)

Blood & Guts: 1-2 (0=none, 5=District 9 & Zombie movies)

Illness & Medical Awfulness: 0 (0=none, 5=Outbreak & District 9)

Scariness: 2, mostly just suspense (0=none, 5=I’ve never seen a “5” but Outbreak gave me nightmares for years – so maybe 5 is Jaws or Psycho)

Other Phobias*: “apocalysophobia”, suggestion of vertigo, aviophobia, hydrophobia, necrophobia (fear of losing spouses or children and fear of death), amaxophobia, fear of conspiracy, and fear of flying giraffes.

Opening Scene:

I can’t even tell what planets those are supposed to be  they’re so wrong. At first I thought it was Nibiru on a collision course with Earth and the Moon, but since there is no further mention of Nibiru I doubt that’s right. And then there’s Saturn with a stripy-like-a-gas-giant moon. Uh-huh. No, Saturn’s moons don’t have gas bands like Jupiter.

And the scale is ALL WRONG on the clip of the Earth and the Moon and the giant coronal mass ejection coming off the Sun.  Of course, you couldn’t fit all three in a dramatic image even if you wanted (the Sun would wash out the whole image, and to get the sizes anything like that you’d have to be on the other side of the Moon, not the other side of the Sun) to so maybe we can pretend it is a split-screen shot. Mm-hmm.

Solar Eruption:

YES! Okay, they got one thing right. They do not call the giant bubble of Sun-stuff headed towards Earth a solar flare as would be tempting. They call it a solar eruption. Technically I’d call it a coronal mass ejection (CME), but solar eruption is at least not reinforcing a common misuse of a scientific term.

Neutrinos:

This is the crux of the whole movie. It’s also the science-y-est the movie tries to get. (And then later they kill off the astrophysicist who gives this explanation – just as well, this science was, what’s that word again? Oh yes, preposterous!)

Neutrino detector – great, it is deep underground, and it’s got those detectors on the wall to make it look like Super-Kamiokande, but the people climb down inside and the detectors aren’t even in a place where they can detect Cherenkov radiation within the water. The water is through a hatch! And the mine is in India – 11,000 ft deep. Super-K is only 3,250 feet deep. It looks to me like our deepest mines are actually around that deep – but they’re in Africa not India.

Some quick look-ups online reveal at least one 2008 paper from Super-Kamiokande  (published in the peer-reviewed Physical Review) that shows no correlation between sunspot number (a measure of solar activity) and neutrino levels. It also does not find a doubling of the number of neutrinos detected during Solar Maximum. Of course, this being the cause of the apocalypse in the movie, maybe we should just let them have doubled neutrinos.

Except that wouldn’t cause the apocalypse – as they say in the movie neutrinos do not interact with ordinary matter! This is why we have to have super-specialized detectors deep underground to even detect a few of them. So they have to turn the neutrinos into microwaves. Well, what can I say to that? If you’re just going to turn gnats into electricity or elephants into ocean waves I guess you can do anything.

Then those microwaves begin to boil the Earth’s core. Oh.

Mass Suicide:

This is what I actually worry about. If too many people believe the 2012 hoax, then there will no doubt be a number who take drastic action. Please don’t. You will wake up just fine on December 22, 2012, unless you do something to change that. Suicide is not a good option, neither is anything that hurts you or those around you. If you feel like hurting yourself is a good idea please go talk to your doctor or call your local helpline.

Maya Prophecy:

The “Maya Prophecy” says nothing about the Sun. The calendar flips over. Ta-da!

Geology:

It confuses me how the cracks run down the middles of streets – turning corners with the street. They worm out of the geology by saying the earthquakes and cracks aren’t due to tectonic shift. It also confuses me that these cracks propagate slowly (at about a walking pace), and that they cut buildings like cake: leaving most of the structure intact.

Soil Liquifaction:

This is a real geology term. It generally requires that the ground be saturated with water and then that an earthquake occurs. It does not mean that the soil turns to water, that rocks melt, or anything like that.

Yellowstone:

Yellowstone is the caldera of a hot spot (not “hot zone”) in our Earth’s crust, and could do some interesting things someday. I’d sure stay away from all volcanic areas (yes, that includes Yellowstone) if the Earth’s core/mantle were heating up. Under the circumstances of the movie, Yellowstone would definitely be unstable.

I like some of the beginning stuff that goes wrong in Yellowstone – the lake drying up (though the dead buffalo is really weird and reminiscent of Close Encounters of the 3rd Kind. I don’ t know why it is dead, it certainly isn’t because of the neutrinos.)

Then there’s something about 2700 degrees C and 0.5% change per hour. Math senses tingling – but I didn’t quite catch everything in this sentence so I can’t actually double-check this.

Later on, the way Yellowstone rolls and explodes into flaming balls of lava is cinematography, but how else would you have John Cusack outrunning boulder-sized “meteors” of flaming rock and a rolling ashcloud first in an RV and then on foot? I mean come on! A movie like this needs a man outrunning flaming balls of rock.

Pickles:

Why?

Charlie Frost’s Explanation of the Apocalypse:

No. And you should be able to tell that from his character and his animations.

Mayan expiration date: yeah, but just flip your calendar and you’re okay again.

Alignment of all the planets with the Sun and the galactic center: No. No. No. There is no alignment of the planets in 2012. The alignment of the Sun with the galactic center either happens every year  near the solstice or will happen in 2300 depending on how exact you want to be. Does this happen every 640,000 years? It takes us 220 million years to go around the galaxy once, and we go through the plane an unknown number of times during that period.

Neutrinos: we already talked about this.

Earth’s core melts: a good part of it already is melted!

Earth crust displacement theory: There was a guy who proposed Earth Crust Displacement – a massive simultaneous rotation of the Earth’s crust, and Einstein did write a forward to one of his books. It is very important to note that this was in the 1950s – and the currently accepted theory of plate tectonics was not solidified and accepted until the 1960s. My geology professors were not taught plate tectonics when they were in intro geology classes, and now even elementary schoolers can explain it. Einstein was very smart, but he did get things wrong, and scientific theories change as we get more evidence that supports or disproves them. When scientists don’t understand something they propose many possible solutions and then gather data – this helps them choose the theory that is best supported by the evidence.

10.9 on the Richter Scale

Personally, I like the Mercalli scale much better when reporting how “bad” and Earthquake was. It isn’t as useful for a scientific study, but in this case San Francisco would have undergone a “12 – Catastrophic – No structures left standing, landscape distorted” which is easy to understand: total chaos. But 10.9 on a logarithmic scale? What does that even mean? (Let me clarify: I have no gut understanding of 10.9 – but it does have scientific meaning.)

“The San Andreas Fault is shifting …” (says Adrian)

Why would the San Andreas Fault (and all connected faults) be shifting if the earthquakes aren’t due to tectonic shift? Script continuity please!

San Francisco slides into the Ocean

If we’re really having non-tectonic Earth crust displacement due to melting of the subterranean crust and core – and a piece of a continent starts to submerge, shouldn’t it be submerging in the mantle? Why does it look like it is just plain sliding into the ocean? I’m not sure the ocean just off San Francisco is deep enough to slide an entire city into. We’re still on the continental shelf at that point, and you’ve turned the city on end to sink it.

Yellowstone Eruption:

I already said it’s preposterous, so let’s look at just a couple pieces. First, it looks like a nuclear bomb blast surrounded by three rings of clouds, probably meant to be shock waves.

Look at this (this is real, it’s from the International Space Station in June 2009):

Sarychev Peak Eruption as seen from ISS

Sarychev Peak Eruption as seen from ISS

That looks kinda similar – but scientists aren’t proposing that the smooth white cloud is  a shock wave, just a cloud generated by changing pressures. Maybe that’s what the makers of 2012 were attempting to portray – a volcanic plume so huge it passes through three different layers of air creating three different concentric clouds.

And yes, you should get away from erupting volcanoes because of ash clouds, superheated ash/rock flows, and worst of all – lahars (superhot, superfast mud flows). Not sure where the lahars would go from Yellowstone, but the best advice in volcano country is to stay out of riverbeds and get to high ground – high ground away from the volcano. These various flows can travel up to at least 300 miles per hour – poor John Cusack he should be so dead.

That ash cloud from Yellowstone reaches DC in just about 7 hours. That sounds okay, it’ll be picked up by the prevailing winds and it only takes a plane 5 hours to cross the country. Of course, it will be somewhat dispersed by then and won’t look like the rolling superheated cloud of the apocalypse so much, but depending on how much of Yellowstone you blew up it could make  a decent ash layer over most of the country. There really wouldn’t be that much heading towards the West Coast though, the winds will push it back the other way.

Cell Phones:

Seriously folks, you’re destroying the world, dumping entire cities into the sea, blowing up continents, and yet somehow, miraculously your cell towers are undamaged and you have signal everywhere? Cell phones are NOT satellite phones, they rely on cell towers. Cell towers are anchored to the ground.

Planes Taking Off, Runways Eroding

Almost every time we see a plane take off, the runway crumbles away beneath it, and the plane goes off the end into a chasm, because it hasn’t reached take-off velocity yet, only to see that plane plummet a few stories, gain control and pull up out of the brand new canyon. This is okay – planes are made to fly – that’s what a wing is for. Engines just give you speed. If you’re already airborne, and you’ve got a good pilot, you can glide the plane until you get your engines under control. And if you need more speed, what better way to get it than going down? Gravity-assisted take-off, I say!

Geomagnetic Reversal

So we end up with the South pole somewhere in Wisconsin. The mechanism is all off, the timeframe is unpredictable, but yeah, the magnetic poles reverse every now and then – every few hundred thousand to few million years. This should not be related to Earth Crust Displacement theory or 2012.

The Physics of Driving a Car out of the Cargo Bay of a Crashing Airplane

I would like to analyze this in more detail. Suffice it to say for now – I think the car should be moving in the same direction as the plane when the car’s wheels touch the snow. If anyone wants to crank out some math and force diagrams on this with me, that’d be great, I don’t have time at the moment.

Boarding the Ark

Two warnings. 1) You’ve got 20 minutes of Titanic to sit through here, but you’re almost done. 2) The drowning scene is not nearly as realistic as the one in the recent Bond flick: Casino Royale. You can probably handle it.

On Board

Now we have mountain-high tsunamis, and our cell phones STILL WORK.

There’s this fascinating thing that is about to happen – with the pretty “v”-shaped cleft that the arks are positioned at the end of, you’ve created what looks to me like a perfect tidal bore: a path for a wave to travel, gaining energy as it comes towards you until you’re hit with the brunt of the energy much harder than you would have been had you been at the mouth of the valley, rather than the back of it. This is what will happen to Olympia, WA if a tsunami ever is positioned just right to enter the Straight of Juan de Fuca and comes crashing down through Puget Sound. Olympia, albeit farther from the source, will be hit harder than Seattle.

Okay, when you designed your arks, and you designed the anchors to fail after the first crashing tsunami, why did you not also design them to withstand things like: crashing into each other, crashing into large debris (like airplanes) in the water, and crashing into rocks? Did you assume that after your anchors failed at that first wave the seas would be calm and you could float peacefully under a rainbow looking for a dove to return?

Africa

Africa gets uplifted, but at this point you can do whatever you want with the tectonic plates because you’ve set up a completely fictional idea anyway. So they set sail and ::phew:: we open the gates and breathe fresh air again.

2012

Update as of 11/2012: I am available to speak to your group on this topic in the greater Seattle area. E-mail me if you’re interested: alicesastroinfo [at] gmail [dot] com.

The 2012 Hoax – The Kitchen Sink

What do the non-existant planet Nibiru, the rollover of the Maya Long Count, a long-expected and non-conjunction of planets, some sunspots, and a lack of reversal in the Earth’s magnetic field, and the continued alignment of the Earth, Sun, and galactic center have in common? They all got picked up and sensationalized as part of a 2012 apocalypse story. This “hoax” rolls pretty much every apocalypse story into one.

Actions – (or “how to talk to your friends about 2012”)

  • Validate – Your friends are intelligent people: treat them as such. Validate their interest in the topic and any correct facts first.
  • Quash – This “hoax” is causing too much panic, so you need to quash it as soon as possible, without being mean. Share facts from reliable sources and avoid getting stuck in arguments that go nowhere.
  • Suggest – Find some common ground. Suggest something real and related that you can enjoy together.

The Maya Calendar* “End” = FALSE

The 13th Maya baktun does roll over on December 21, 2012 – this is often referred to as “the end of the Maya Long Count.” As with many cultures’ calendars, the Maya calendar uses different periods of time than the calendar stuck to your fridge right now. They use 5 numbers to represent a given date, called the Long Count. A baktun = 20 katun, a katun = 20 tun, 1 tun = 18 uinal, 1 uinal = 1 kin (which is one day). Americans usually use only three numbers: year, month, and day. Both cultures have designations for larger periods of time also, we just don’t track them as closely. For instance the Maya have a calabtun which is over 3 million years, and we have millenniums – 1000 years each. Just like your car odometer, when one of the dials reaches “9” the next numeral to show up in its place is “0”, when the baktun counter of the Long Count reaches “12” it rolls over to “0.”

Picture: Kyle May

Picture: Kyle May

It is just like flipping a calendar, or when the odometer on your beater car finally rolls so high that it reads 000000. We were all very excited when we got to turn over all the numbers in our calendar on New Year’s 2000 – so I’d be just as excited about 12/21/2012 if I used the Maya calendar in my daily life.

Nibiru = FALSE

Nibiru is the name given to a non-existent planet supposedly discovered by the ancient Sumerians (2200 B.C.E. and 1600 B.C.E.). This was entirely made up by Zecharia Sitchin in several fictional novels that he has written since 1970 about ancient Mesopotamian culture. Nancy Lieder, a “psychic,” built upon these stories, saying the Earth was in danger from Nibiru in May 2003. Nothing happened in May 2003 so the “end” of the Mayan calendar was rolled into the hoax, giving the date December 21, 2012 as the “real” date of the disaster.

Polar Shift = FALSE

In the geologic record there is strong evidence that the Earth’s geomagnetic field reverses polarity every several hundred thousand years with no regularity. There is nothing to suggest this poses a threat to life on Earth, and scientists can’t predict when the next one will happen even to the nearest 100,000 years, let alone to the nearest decade.

“Polar Shift” refers to something different though – it refers to a physical change in the tilt of the Earth. This may have happened to Uranus in the past, and generally requires being slammed into by something very massive. There is nothing that massive on a collision course with Earth within your lifetime.

Planetary Alignment = FALSE

The planets will not be aligned on 12/12/2012. Here are their positions:

12/2012 Planetary Positions

12/2012 Planetary Positions

Noon 12/2012

Noon 12/2012

If you look at this other view of the same picture, they look aligned, but bear in mind that line is the ecliptic – the line through the plane of our solar system. All planets are always “aligned” along this line: every moment of every day of every year. That is the definition of the ecliptic.

Solar Maximum = TRUEISH

The solar activity cycle lasts about 11 years, and the last maximum of activity was in 2001, which would imply a maximum in 2012. It’s pretty neat, get a trained astronomer to help you carefully observe sunspots (always use approved filters to observe the Sun, never look directly at it!). The minimum of activity we’re in right now is a little odd, so some solar scientists are predicting the max won’t actually occur until 2013. The most major flares don’t tend to happen until just after the maximum though.

Galactic Alignment = TRUEISH

The Sun, the Earth and the plane of the galaxy will be aligned on December 21, 2012. Of course, they’re aligned around about every winter solstice – it depends how you define the plane of the galaxy. You see the galaxy has thickness, and we’re in the middle of that thickness, and will be for several million more years. Seems aligned to me.

13 baktun (or 20 may) is when the Long Count rolls over
1 pictun = 20 baktun = 2880000 days (about 8000 years)
1 calabtun = 20 pictun = 57600000 days (about 150000 years)
1 kinchiltun = 20 calabtun = 1152000000 days (about 3 million years)
1 alautun = 20 kinchiltuns = 23 040 000 000 days (about 63 million years)

Talk Coming Up! 2012: the Movie, the Astronomy, and the Hoax!

Hey all!

Pacific Science Center’s Science Cafe team just asked me to host a talk/Q&A at the next Science Cafe: TUESDAY, November 3! I’m going tackle “how to talk to your friends about 2012.”

Join us next Tuesday, November 3 for a myth busting Queen Anne Science Café. As we approach 2012, TV shows, new books – even a new movie – all sensationalize the idea of the world “ending” in 2012. Our next Science Café, 2012: The Movie, the Astronomy, and the Hoax, will debunk any fears you may have about the end of the world. Don’t miss a fascinating evening of science, drinks and hoaxes, 7:30 p.m. at T.S. McHugh’s.

Don’t worry though – it is an all-ages event, so bring whomever you’d like. The talk will be Cafe-style: shortish followed by plenty of question and discussion time. See you there!
