Are There Morons On Other Planets?

Mankind, on the whole, is pretty cool. Sure, we've had our missteps - reality television and Hitler spring to mind - but by and large we're not un-fun to hang out with.

Our story is an epic mostly comprised of an awfully long and rambling chapter about survival. Chapter 2 details how, better than any other species on the planet, we managed to gut it out and arrive on top of the food chain. If you're able to read this that means we're still doing a-ok. Yay us!

But now that we have a chance to pause and catch our breaths after all of that surviving nonsense, we find ourselves asking the big questions. Is Elvis still alive? If it were the early '80s and Phoebe Cates hadn't met Kevin Kline yet, would I have a shot? And, are we intelligent beasties on our own?

When you look up at the stars at night do you imagine life out there? (excluding the International Space Station - now the brightest star in the night sky - because it's not really a star so to count it would be cheating)

A short while ago in 1960, before Phoebe Cates was even a twinkle in her daddy's eye, Dr. Frank Drake cooked up an equation that would help us figure out how much intelligent extraterrestrial life was in the galaxy that we could sit down and Skype with. It's known as The Drake Equation and if you could figure out what numbers to plug into all the variables you could arrive at the answer. The only hitch is figuring out the variables. Here. Take your best shot:

R^* is the average rate of star formation in our galaxy.

f_p is the fraction of those stars that have planets.

n_e is the average number of planets that can potentially support life per star that has planets.

f_ℓ is the fraction of the above that actually go on to develop life at some point.

f_i is the fraction of the above that actually go on to develop intelligent life.

f_c is the fraction of civilizations that develop a technology that releases detectable signs of their existence into space.

L is the length of time such civilizations release detectable signals into space.

Once you've filled in the blanks you can multiply all those together to arrive at:

N: the number of civilizations in our galaxy with which communication might be possible.

Easy!

I don't know what you got, but me and Frank figured the answer to be 10.

10 other civilisations to compete with for god's love. Y'know, odds are we're not his favorite... Just sayin'.

So if we accept that there might be 10 civilizations capable of holding up their end in a game of pan-galactic pictionary, how many more could there be in the universe at large? Drake's equation only accounts for what we know about our own galaxy. What about the other galaxies? There's a fair few others. Right?

My dear friend, I like you, but you've just gone and wildly understated things. Again.

Allow me to try and illustrate just how bone headed your "fair few others" comment was.

"Galaxies. Very bad. You go first."

Here's an image showing a tiny fraction of the night sky taken by space perves at the European Southern Observatory.

I know what you're thinking. "Someone sneezed stars. Big deal. Seen it..." Right? Only, you're wrong again. These are galaxies. Quintzillions of 'em! Each one home to hundreds of billions of stars. And if we were any closer (10 billion light years give or take) they'd have us for lunch! Sure, Andromeda has first dibs, but Andromeda is a pussy. (Note: The big blips in the foreground? Yeah, okay those are stars in our own galaxy that stubbornly refused to clear the shot. They're just lucky Christian wasn't around. What we're talking about is the stampede of galaxies beyond those. Keep up.)

Now you're thinking "Great. You've just gone and blown my mind. Now what am I supposed to do about it? Feel all humbled an' shit?"

Heck, no! I say, do what I do. Visit Galaxy Zoo and get a kick out of insulting other galaxies one by one, and by extension, all races who live there! Did I also mention you get to have fun playing an addictive game of "classify the galaxies" AND get to feel good about yourself for helping to further science? I did?

Come on. Be a space perve too. Everybody's doing it. Probably even Elvis!

Sample insults to help get your creative juices flowing:

"Puny Clactadarians! Your galaxy is like a frisbee that was left on the dash of my car and warped in the midday sun!"

"Pitiful Oolabaalians! Your spiral galaxy has a mere two arms. Not spirally enough!"

"Cowardly Nargazoids... You call that a galaxy? Look, here comes another galaxy to eat you up! And about time too!"

Think you got it in you to better that? Bring it, sunshine. Oh, it's so ON!

(With thanks to Phil Plait at Bad Astronomy for tipping me off to this. But you still owe me a beer.)

You Can Run, Jupiter, But... HEY! Where'd It Go?

This one is something to marvel at. Have you ever wanted to experience 30 hours in 11 seconds? Have you ever wanted to keep a close eye on Jupiter in case it pulls a fast one? Have you ever felt so down you just wanted to hide behind the sun?

Check, check, and check?

Then this post is for you!

Phil Plait, that baddest of bad astronomers (and I mean that in the same way "F*ck You, Sara" really means "I love you" at the end of The Last Boyscout) has posted a short video of Jupiter and its moons trying to insulate itself from all earthly wrongdoings by putting the sun between us and itself. Can you blame it?

Phil is one of my favorite bloggers. He's the guy that took the Moon Hoax crackpots head on in his first book, Bad Astronomy, and has subsequently become a blogging god, talking about all things majorly astronomical, sciency and rational.



By the way, if you ever wondered how the world is going to end then you might like his new book Death From The Skies (free plug, seeing as how I like the guy so damn much). Otherwise keep checking that Large Hadron Collider link I gave you a while back, for up to the minute intel.

Oh, and don't forget to become a rabid devotee of Phil's Blog if you weren't already.

Science Part. 1

Yawn, right?

Science is dull, dull, dull.

You can't make the Periodic Table of Elements fun, I don't care how much clown makeup you slap on it.

Or can you...?

Okay, sorry I used that clichéd device. I hate myself for it almost as much as you do right now. I promise it won't happen again.

Or will it...?

I'm not too proud to go on record as saying "science is hard." I don't have a head for it but that doesn't mean I can't appreciate it. Why does it have to be so effing hard? Probably because it seeks to quantify how everything in existence actually works. You try explaining precisely why the sun is hot and just how hot is it and see how much accurate detail you can get with laymans terms and a slide rule.

If you're one of those people who hate science with a passion bordering on "Quit Dry-Humping My Leg, Bitch" then you are not alone. Plenty of fruit loops think the world is going to hell in a hand-beaker owing to science and its all-consuming hunger for advancing the quality of life.

Science has given us medicine. So now ignorant a-holes who otherwise wouldn't have lived long enough to complain about how unnatural chemicals are can protest the devastating effect H2O is having on our embattled planet.

It has given us power. So a-holes can boot up their computers and whine online about how it used to be so much better back in the days when wearing filth for weeks at a time was all the rage.

It has given us computers and the internet. So a-holes with computers and internet access can whine about antiscience a-holes who think we would be so much better off living with famine, disease, unsolved murders, warm beer, radios that don't do squat, guns in briefcases on airplanes, the earth being flat, and Steven Spielberg out of a job.

F*ckers.

But can you blame them for their ignorance? In the past Science education managed to do more harm than good. Remember how excited you and your mates would get at the prospect of watching yet another science program detailing all the hip experiments you could do in class?

Me neither.

To jog your memory, they go a little something like this.





But isn't Science also capable of great evil? Like those scientists trying their darnedest to destroy the planet with a Large Hadron Collider, say for example?

In short: nope. Science as a principle isn't evil at all. You might get the odd individual who is capable of evil and chooses to weild knowledge gleaned by science in an inappropriate manner. Like, say, an extremist with a dirty bomb wandering downtown Manhattan. But for the most part the purpose of Science is the persuit of knowledge. And knowlege gives us answers to questions, which helps us solve problems. Problems like: What is the best way to squander billions of dollars in an effort to suck the world as we know it into a black hole?

Actually, that's not what science is trying to do with the LHC and I think you'll find that those doomsday predictions are only being touted by people who are entirely ignorant of the science involved - suprise, surprise.

Just what is the LHC really doing then? Apart from cutting record deals? A good place to get the lowdown is here. If you're curious.

Otherwise just sit back, crack open your favorite beer, and wait for it all to end.
