Far more serious than beaming a salted snack advert into space, scientists at Pennsylvania State University in State College suggest that if we really want to catch the attention of aliens, then we should cover half the moon in mirrors, and send coded flashes of light into space. Always assuming ET's not too bored by us, that is.
Properly angled and lined up to reflect light from the sun, the mirrors could be used to increase the amount of light reflected by the Earth-Moon system by up to 20%. Any alien eye scanning the heavens—or, more likely, an automated system like SETI set up by aliens—should be able to easily spot the modulations. A set of prime numbers in flashes would be a good choice, since these are easily distinguishable from natural variations. Furthermore, pop photovoltaic cells on the other side of the mirrors, beam the energy to Earth by microwaves and you'd have enough power to seriously impact the climate crisis. Not a bad idea, eh?

Nice 'chop to whoever made that pic!
I dunno if this is such a good idea. I mean, I shine reflected sunlight at people walking outside our dorm, and they've tried to kill me on more than one occasion.
I don't think the best way to introduce ourselves is by blinding them until they get SO FREAKING ANNOYED that they greet us in return with a planetary death ray.
2010... Giant moon mirrors attract universes most vain alien females. Fashion sector profits jumps %27.
I think remaining unknown to aliens (or whomever is out there) is a good idea, at least till we can get our collective "shit" together here on earth. Why ask the neighbors to stop by when we are busy squabbling with each other.
Do you know what ET is short for?
Because his legs are only 7" long.
@Curves:
your inappropriate use of 'whomever' is exposing your false erudition.
I already know that my pointing it out exposes my very real assholishness.
Aliens are a fantasy, like unicorns, the boogie man, human-induced global warming, and the tooth fairy.
I, for one, would like to welcome our new overlords.
@Slartibartfast:
I thought ET was short for Eddie Torrez, the extra testicle?
We Are...
Wasn't somebody already working on something like this? Oh, yeah...
+ Watch video
so mirrors on the moon to attract aliens?
sounds like a government cover up to build a death ray that can vaporize an entire country.
where do i sign up?
Maybe a personal add... After all didn't we all learn from Captain Kirk?
Bring on the Blue and Green Chicks
Proposal DENIED! ...cause it's dumb
it might push the moon out of alignment and then cause world distaters everywhere and ET might not be able to get to us in time to save us from ourselves_
@Stang70Fastback:
Ha! We used to do that to people in their dorm rooms just after they returned home at the end of the day and were changing their clothes. Good times those were. I bet nowadays you'd get arrested and/or sued. (PAR southern exposure to FAR northern exposure rooms at the good ol' U of Illinois.)
@Curves: I agree. I think it much better that we find them, as at a minimum that means that we are more likely to have the advanced tech to survive them being pissed at our general douchebaggery.
I think putting mirrors on the moon advertising our presence is like sitting in the woods covered in hamburger and honey while making Kodiak calls. Its just asking for trouble.
And whom is Slartibartfast? He seems like the kind of guy that would get us blasted by aliens when he breaks out the Strunk & White to correct their translator.
You know what would catch their attention even more? Carve the letters CHA into it with a laser.
So where is the money for this supposed to come from? I mean gathering solar energy and microwaving it back sounds great, but how about a little bit of government spending on something a little more terrestrial, maybe even domestic. I guess that is too rational to hope for, I mean it isn't like we are in a recession and lacking good, affordable healthcare/education/energy/food/etc. in this country right?
or we could just call them. I mean E.T. phoned home, why cant we just trace that call? star six nine that sh*t
@zenpoet: I for one believe your hamburger honey Kodiak cat call proposal is ingenious.
Humans have barely discovered space for a few centuries and we're already looking for aliens? Can someone remind those looking for the aliens that not only do we have to search the vast expanse of the universe, but also make sure that they currently exist at the same time as us.
Cobra Commander approves of this idea!
@Slartibartfast: Whatever. Or to show my false erudition: w'ever.
Statistically speaking there has been intelligent life somewhere other than Earth, but by those same stats it is highly unlikely that they exist at this point in time or anywhere near our proximity among the hundreds of billions of stars in our own galaxy, let alone those of distant ones.
@ripfire4: you made the point before I did - considering humans have been around less than a fraction of a blink in the history if the universe.
What if this gives the aliens epileptic seizures?
All we have to do is allow porn to be broadcast over the major networks (ET just loves herself some American Idol), and that will get their attention.
What about all the radio energy our planet has been emitting for decades?
Doesn't that have a jump on our mirror idea, and more scattered to boot?
Have we tried a boot?
What would it's carbon footprint be if we did?
While I like the idea of beaming free energy down to earth, it does seem a bit counter-intuitive to solve global warming by adding more energy to the system.
@Rabid Penguin: Oh, you mean like God, the afterlife, altruistic republicans and the virtues of capitalism?
Does anyone ever think that maybe Aliens might not be so friendly? I mean we can't even get along with our own selves so how's that gonna pan out when Aliens come into the mix...?
@bpapa9013:
Wow... the gloves are off I see. I know that you've probably tried really hard to do your part in causing the world to heat up, and I didn't mean to take that away from you... I'm sorry.
I'm pretty sure they've been monitoring our politics, reality tv, genocide, racism, religious fanaticism, greed, abuse of the environment and general ignorance for years now.
Wouldn't you stay away?
@strider_mt2k: I imagine that as the signals travel out to space, it disperses and degrades into noise.
@bpapa9013: Don't insult my church of the flying spaghetti monster or I'll smite you with some spicy meat balls!
I would imagine that any life forms capable of traveling across the galaxy would have the means to detect intelligent life on a planet without mirror signals on the moon.
Also, we may never actually get to meet them, since they'd think our planet is one big fucked up disco center, what with the disco ball hanging in orbit.
@Kaiser-Machead: I don't know if it's a urban myth...but have you heard about some TV broadcast that bounced back from space decades after it was broadcast?
@johnnyabnormal: I do honestly apologize if I offended any followers of the the great FSM, everyone else however can sit & spin.
@P3nnst8r: I will fund it if you would care to be the test subject. Then we can send our results to the moon-mirror people and see what they think.
@Kaiser-Machead: Doesn't most of it start as noise?
@Gann: Our total population increase is proportional to the planet's resource depletion rate. After all, the stuff we are made of has to come from somewhere.
As for global warming, yeeeaaah we gotta do something about that.
@bpapa9013:
That's kind of an odd comment... I thought atheist, socialist, democrats, were supposed to be a compassionate people.
But I digress, this article is about aliens and moon mirrors.
If aliens did exist, what if they lived on the moon... what would they think of us if we paved over their planet with mirrors? The alien porn industry may not mind, but think of the children.
@Rabid Penguin: wow, nice non-sequitur. I apologize if you were joking in your first post, because I wasn't joking with mine...
@zenpoet: Only when it's from yo mama!
Sorry, very very bad taste.
I see some people don't think aliens exist... I suppose you believe in god though don't you?
But of course he exists... its in the bible.
I'm not saying aliens are Definitely out there. (i think they are but i can't be sure)
But its far more likely that they exist than it is that some all powerful god exists.
@luciusad2004: your about to have a penguin up your @$$...
*you're, sorry brain faster than fingers...
