The gigantic smiling head that orbits our planet belongs, of course, to Brian Cox. He’s a particle physicist and a university professor who also makes decent telly programs about space for the BBC and makes your mother a bit aroused. He seems like a nice, cheerful sort of a chap -- certainly the kind of person that you would rather hire a boat with for an hour than purposefully direct towards a sniper battle in a landfill.
So in a pub last week, if I had been the Supreme Leader of Planet Earth instead of just mildly alcohol poisoned, he was the person I would have chosen as my ideal ambassador for humanity in the eventuality of aliens ever landing here.
I think I owe Brian Cox an apology.
Aliens almost certainly exist. If you don’t think they do, you might just be a bit confused about how big the Universe really is. Have a look at this for a cheeky refresher – that’s just the bit of our galaxy and beyond that we can see and take photos of. Each one of those dots is a star like ours, and a source of energy to the planets caught in its gravity, just like ours, each a hub in space for all of the same elements we’re made of, and each governed by the same physical laws that arranged those elements into something like us. There is estimated to be between 200 and 400 billion stars in the Milky Way, our galaxy, and at least hundreds of billions of galaxies in just our bit of the Universe. Not that these numbers mean anything beyond stonkingly flipping massive by this point, especially considering that the pesky Universe hasn't proved itself to be anything but infinite just yet. Basically, we might as well say there’s a sillion bananillion gorillion stars and planets for the amount it helps us to comprehend the situation.
However, the reasons that aliens almost certainly exist are also the exact same reasons why we will probably never meet them, and also the exact same reasons why we never want to.
Our nearest star, Proxima Centauri, is about 4 light-years away, or 24,000,000,000,000 miles from us. To not help put that in some form of perspective, the interstellar probe Voyager was launched 33 years ago and has only just begun to breach the edge of our solar system 10 billion miles away. It will be another forty-thousand years before it reaches even the very nearest planetary system to us. Me, you, Earth, the solar system and even Brian Cox are all effectively lost in this cosmic quarantine. Even the 100 light-years our radio broadcasts have travelled seems as about as significant as a widowed ant's anniversary plans when we consider that our Milky galaxy alone is 100,000 light-years from end to end. The space we’re hiding in is just so massive that the statistical improbability of advanced alien civilisations finding us is great enough that you could assume the word astronomical was invented for occasions just like this unnecessarily insulting sentence, idiot.
That’s also based on the slightly smug assumption they would want to find us at all. There are more stars just like ours than there are grains of sands in all the deserts in the world, so if life exists here and at least one other place, then it’s logical to assume it exists everywhere. Suddenly, we’re not the special, magical wonderstuff that invented trousers and bread; we are insignificant, common, generic. Like every commodity in existence, life is worth less when it is in abundance. We treat pandas kindly because they are rare, but we’ll happily plough a minivan through a parade if we think there’s the slightest chance we might kill an extra wasp. Aliens, if they’ve found us, and that’s generally the kind of thing they like to do, could have found so many other planets and life-forms that they would probably regard us with the same level of enthusiasm we’d devote to Paris Hilton’s opinions on anything more complicated than a sausage. The chances are, they won’t fawn over how impressive we are, or invite us to join some intergalactic ride-sharing space union, or begin imparting their advanced scientific knowledge to us. No, they’ll probably stop for a photo, giggle at an aeroplane, and move on.
It’s exactly because they might be like us that we don’t want to meet them. To reach Earth, extraterrestrial life would need technology whereby they could travel trillions of miles in their life-spans, and we’re still executing each other with lumps of metal to get the best price on a finite, black liquid we have to burn to get to the shops. I mean, seriously, have you fucking met us? Think about how well humans historically have treated life-forms they see as inferior to themselves. Ask the Native Americans how being friendly to visitors turned out for them. Ask an African a few centuries ago how excited he was to see a boat. Ask the dolphins and penguins in the zoo how they came to the peculiar decision to move to a fish-tank in North London. Humans don’t discover anything and think ‘look at this thing doing absolutely fine without us.’ No, we bomb it, dig it, skin it, mine it, catch it, poke it, spill it, lose it, break it, plant a flag for the press conference, move in the bulldozers and set up a gift shop.
So while “Hello. Let there be peace everywhere,” might sound like a confident message to sling deep into the cosmic dark with a trail of breadcrumbs home, perhaps we’re more like the lamb that’s rolled itself in herbs and butter and is lolloping happily towards a man holding a pita bread, a shotgun and a barbeque.
These bloody aliens apparently possess wizardry that allows them to bound across time and space just for a laugh, and I was going to send Brian Cox to go and shake their hands/claws/tentacles like we’re equals? No, no, no, I’ve changed my mind. I’m so sorry, Brian. At the very first sign of a spaceship landing, please take my lovely, smiley Brian Cox, put him in a helicopter with a pencil and get him up a mountain somewhere thinking up new ideas for super guns.
If I can choose again, I vote for someone with at least one finger up their nose, a face that could divert traffic and a name like Wally Fumblebricks.
Better still, send a pig in a cardigan and hope they don’t figure out we’ve got 20,000 nukes.
