Are the Extraterrestrials (ET for short) out there somewhere. What are the odds of there being ET's out there? And if so, what are the odds of communicating with them?
The known universe is extremely large, beyond my apprehension. Just take a good look at one of Hubble Space Telescope's deep field pictures:
Just look at all the galaxies!!! All those galaxies have many, many stars and most of those stars have planets. That means there are so many planets in the universe that there is no number I know of that could express just how many there are. Now, don't you think that on some of them life of some sort must have gotten a start. It could be as simple as lichens but you have to admit that the are odds are very favorable for life on other planets in other solar systems and just think, there may be multiple universes, the multi-verse theory.
There is one huge problem. The distances are so very great, that it would take thousands of years for even radio waves to reach them. The closest galaxies are the Large and Small Magellanic Clouds, 160,000 light years to the LMC and 200,000 light years to the SMC. If there is life somewhere in these two closest galaxies, there would be no way of knowing unless they invented radio back 200,000 years ago or so.
The distances are just so very great that we may never know if there are any planets with life. Even if there were, the life may be nothing more than lichens or one celled organisms that far back in the history of our universe. So, are we alone? I don't know but I would like to think that we are not. Now go outside tonight and see if you can spot any flying saucers or aliens or. . . just have a good day, you hear?
