This just in, you don't matter.

The U.S. population is 316+ million, while our planet has more than 7 billion people on it and the Milky Way (our galaxy) contains about 500 billion stars.

One estimate suggests that the Universe contains more than 100 billion (or 10 to the 11th) galaxies. One can guess that there are likely at least 70 sextillion, stars or 7 × 10 to the 22nd. stars in the Universe (remember, not every galaxy is similar in size and quantity of stars, 70 sextillion is likely a gross understimate). The universe is part of??? The fact of the matter is you don't matter even on a national level (nor do I) and we are a joke in our arm of the galaxy, our arm of the galaxy is a fragment of our galaxy, our galaxy doesn't even begin to matter at a universal level and our universe is potentially a tiny spec in the grand scheme of things.

Note, my above figures are fairly conservative and made with a lot of liberties. I’ve seen the Milky Way estimated from anywhere between 200 and 500 billion stars for example and the galaxies in the universe figure is likely low too. There could easily be septillions of stars (or more!)

So really, someone tell me why we do nonsense like fight, argue, be petty about the most idiotic things? Why do the Kardashians matter? Why does American Idol matter, why do YOU matter? Why should I like your kid's photos on Facebook, should I really care that you are battling cancer? Should I even get out of bed Monday and go to work because when you think about it the Universe doesn't give a rat's ass and whatever it is part of doesn't either. I dunno, maybe I'm a damn fool for thinking about it but hey... what do I know. All I know is existence is far greater than we can imagine yet we focus and obsess about petty shit in our own lives and think we are all the center of existence when the fact is in the grand scheme of things we do not matter in the slightest.

Don't get me wrong, don't take this as a message to just give up. BETTER YOURSELF! Expand your mind, contemplate existence, find something constructive to do, apply yourself to bettering the lives of those around you. Do something for someone else. Learn something. Stare up into the night sky and think about what you are seeing for a few minutes.

 


If we take a look at our own solar system and count the currently defined planets; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune we know of life on 1 in 8 planets. Let's assume this is actually a high percentage and that 1 in 100 planets has some sort of life.

A septillion is 1,000,000,000,000,000,000,000,000 so that gives us 10,000,000,000,000,000,000,000 worlds with at least single cellular life. That's 10 sextillion worlds.

Ok, so let's assume 1 out of ever thousand worlds has multi-cellular life. That's 1,000,000,000,000,000,000 worlds, 1 quintillion.

Now let's assume out of those 1 quntillion muti-cellular worlds that 1 in 1000 has something resembling animals. 1,000,000,000,000. That's 1 trillion worlds with animal life.

Let's assume 1 in 100 of those have some sort of sentient life that has developed the use of tools, even if they are primitive. That's 10 BILLION worlds.

10 billion worlds scattered among 100 billion galaxies gives you a 1 in 10 chance of having tool-building life in your galaxy. Then you have 13.8 billion years to spread those out over.

With such a conservative estimate, it is highly unlikely that we will ever encounter a sentient species that originated on another planet.

We could easily change those numbers for our favor though. Say 1 in 2 stars has a planet or moon that supports life. 500,000,000,000,000,000,000,000 planets with life. Say 1 in 2 of those has tool building life, 250,000,000,000,000,000,000,000.

250 septillion planets with tool-building life. That gives you an average of 25,000 tool-building worlds per galaxy. That's still only a 1 in 20 million shot that any given star in our own galaxy hosts a planet/moon with a tool-building race on it. Then factor in that the Milky Way is estimated at 13.21 billion years old, consider humans are only about 200,000 years old and that civilization only goes back 10,000-25,000 years old (if you believe that that Bosnian 'pyramid' is a human creation then 25,000 years) and that we didn't land on the Moon until July 20, 1969 and it is the farthest we've ever sent human beings...

Now let's assume that in the first billion years of our galaxy, there were ZERO tool building species. That leaves you with 12.21 billion years to divide 125 billion civilizations over a galaxy with 100,000-180,000 light year diameter. Let's assume 140,000 light years. That's more than 15,000,000,000 square light years.

That gives us a little over 8 tool building civilizations per square light year spread out over 12 billion years.

It sucks. I want to meet an off-world species soooooo much, better I want to travel to some of their worlds and see them with my own eyes. But, unless we figure out immortality I won't be holding my breath.
