Life Outside Our Planet?

                                            Star Cluster NGC 265
                                        This image is a cluster that is 1/10 the diameter of the Moon...

...In other words The Universe is HUGE!  Earth is inside a giant galaxy called the Milky Way.  The Milky Way galaxy is estimated to be 100,000 light years across. A light year is roughly 5.9 Trillion miles.  This means our galaxy is about 5,900,000,000,000,000,000 across.  That's a lot of zeros.  I actually had to look up what comes after quadrillion, the answer is quintillion.  Our galaxy is about 5.9 quintillion miles across.  It has about 300 billion stars and about the same amount of planets.  Its is estimated that at least 10 billion of these planets may lie in what they call a "habitable zone."  This is where a particular planet orbits it's star in a similar spot where Earth orbits our Sun.  What's my point?  My point is there are billions and billions of galaxies like the Milky Way.  Don't you think it would be silly to think that there is no possible way that there is any form of life outside of Earth?  It's naive to think that we are alone in The Universe.  It shouldn't matter whether you believe in God or not, it's pretty much common sense.

It's almost comical when I see people write or hear them talk about how they think there is no life outside of our Solar System.  How could it mathematically be possible that we are alone?  It can't be possible and it isn't.  I am not saying that there are little green men roaming far away planets.  Life comes in all kinds of forms.  From bacteria to viruses to animals to plants.  There HAS to be some of that somewhere other than here.

There very well could be intelligent life somewhere else.  In fact, they could be so far ahead us in technology that they don't even care to visit us.  Think about how far we have come technologically in the last 150 years.  Can you imagine if there are life forms on other planets that are 1 million years ahead of us?  They don't need our resources, they don't need to probe us, and they don't need to abduct us.  They may not even have a way to get to us.  Think about this.  Even if we had some how figured out how to travel at the speed of light, it would take us 25,000 years to get outside the Milky Way from where Earth sits today.  So, a possible visit from any other life form from another galaxy is most likely never going to happen.  The only way this could ever happen is if they are so far advanced they figured out how to not only travel 100s or even 1000s of times faster then the speed of light, but also they would have to go into some sort of hibernation or a cryogenic state to survive long enough to get here.  Another way they could get here faster is to bend space.  Try this little experiment.  Take a piece of paper and draw a circle on both ends.  These represent galaxies.  Lets say that the space in between both galaxies are 1 billion light years apart. Now, let's bend space!  Grab both galaxies and bend the paper in a "U" shape so now the galaxies are almost touching.  We just bent space and now they are 100 light years apart. Tada!  So if they figured out how to travel at 100 times the speed of light, they will be here in a year.  Pretty crazy to think of, but hey who knows?

It's tough to know exactly what's out there but you got to admit there HAS to be something someplace somewhere somehow someday sometime.


Cheers!

  1. Hey Kyle, it's Paul. Did you write this blog just to get me out of the woodwork? If so, congratulations. If not, meh. Any-who, I say it's arrogant now-a-days to believe we are the only life in the universe. We are still finding and classifying new types of lifeforms that don't fit in with the genetic make-up of known life. Good Example: The vent worms. They are those creatures that live off of ocean geothermal vents. They find nourishment in an environment devoid of the sun and in temperatures of water that are lethal to all other known forms of life. These creatures consume minerals to survive. If that's not explicit proof that we need to keep our eyes out for any kind of life in any kind of form. An not in just terrestrial form either. Why couldn't there be creatures that evolved in space?

  2. Thanks for commenting Paul! You understand a lot more than some others. When they think of "aliens" or "extraterrestrial life" they think of little green men, rather than a worm, or bacteria, or SOMETHING other than a being with 2 arms and 2 legs. Life is life. There is no way I would ever think for a minute that there isn't something that is alive on another planet somewhere. There just has to be....law of averages right? Share this blog Paul.

  3. OMG! Your friend Paul took the words right out of my mouth! Or maybe I should say-word. Arrogant!! I totally agree that it's "arrogant" to think that we are the only life forms around! I've been saying that for years!! As you said, it's mathematically impossible!! Great blog Kyle!! 100% agree!!

  4. Oh sorry, I meant to link this into the earlier comment. Here is an idea of the size of the universe. http://htwins.net/scale2/
