Theory on Alien Visitation, and why it will probably never happen
The Universe is Big. Really, really big. It’s so big, we’ve barely scratched the surface of what’s in it. It’s also old. Really, Really
old. Latest estimates have the Universe at 13.8 billion years old. That’s an awfully large number of candles on birthday cakes.
Now, our own Solar System is about 4.6 billion years old. That’s also pretty old. Not as old as the universe of course, but still.
Let’s take a look at probability. Given our own Sun is 4.6 billion years old out of a 13.8 billion year old universe, that’s only 33.33 %, or
about one third. We already missed two thirds of the time during which things existed in the Universe, before our sun was even created. That’s 9.2
billion years, it’s also a really, really long time during which many things could have happened.
In our own Solar system, there are 8 planets. Well, arguably 9, or 10, but who really cared about Pluto or Planet X? OK, I know that somewhere out
there there is a “Flat Pluto Society” and there are a ton of people seemingly believing that Planet X is going to swoop by and wipe us all out one
day, so I have to give those folks a quick nod hello.
So already, we’ve ignored 76% of the history of the Universe, and 7 out of 8 of the currently known planets for discounting intelligent life.
Now, there are a number of theories as to the age of the Earth. Rocks have been found dating back 4.3 billion years, which is the best empirical
evidence we can use as to the current age of the planet. Some Christians will, of course, let you believe that the Earth is only 6,000 years old.
They also believe in invisible beings in the sky that know when you've been good or bad, but think kids who believe in Santa are crazy, but I
digress.
Out of that 4.3 billion years, humans have been around for 200,000 of them, and civilization has been around for about 6,000 years. Now, humans have
been broadcasting radio signals into space for about 100 years, ever since Marconi’s first signal, and these have travelled about 200 light
years.
So for about 100 years out of 4.3 billion, we’ve been telling the immediately local universe that there is intelligent life here. That’s
0.000000002 % of the time that the planet has been around, during whatever time someone who lives in the immediate vicinity may have been watching.
Out of the millions of species on Earth, only a handful have evolved to the point where they can use tools, and only ONE has above average
intelligence useful for learning science and math. Out of the 7 billion people on the planet with this ability, only a few thousand of those people
have the advanced knowledge to be able to send communications into space, or for that matter, spacecraft.
The universe is largely thought the be about 93 billion light years across. So for 0.000000002 % of the time that Earth has been around, civilization
has been sending out a random signal to 0.0000000025% of the Universe, hoping someone will hear it at the particular time in their own development
that we assume is similar to the 0.000000002% of the time that we’ve had communication ability.
And wondering why no one called back, or came to visit.
