5 Reasons the Aliens haven’t contacted us.....
1. The Universe is Too Big
The universe is rather large, in case you needed reminding. Our closest neighbouring system, Alpha Centauri, lies a miniscule 4.37 light years away from us. That's roughly 25.6 trillion miles in Earth terms. I’m leaving out the zeroes of course. All twelve of them.
That’s really quite close! Assuming that we can get anything bigger than a light particle to reach those kinds of speeds (unlikely), we’d still be quite alive upon reaching our destination.
Of course there is the small matter of the micro-meteorites that might hit us on the way, the lack of an external power source, long periods exposed to cosmic radiation, the prospect of making baby in space, and the fact that 25.6 trillion miles is a laughably short distance to travel. Space isn’t designed for us. We must design for it. That might take some time.
And so the argument goes, that by the time any species reaches the point at which interstellar travel is possible, they’ll have either long been squished or have squashed themselves. This leaves us with a universe of brief sparks. Life sprouts into existence on an infinitude of lucky planets, has it’s moment in the sun, and then withers in a short space of time, leaving nothing.
Personally, I don’t buy the theory. We paste our own insecurities and ineptitudes onto it. The universe is also very old. Alien civilizations have had a long time in which to advance. Surely a meteorite could have avoided one? Surely one could have resisted the temptation to exact devastation upon itself?
Ask a Roman Trireme commander to cross the Atlantic Ocean. He won’t react much, given he’s a skull. But if he could, I’m sure he’d laugh his jawbone off. Looking at history as a precedent has its limits, but 25.6 Trillion miles could be a short trip down the shops, given time.
