I would like to believe aliens have visited earth and we will meet them someday. Unfortunately, there is no real proof that they ever have visited
Earth. There are certainly anomalies and other artifacts that defy logical explanation, but, there is not any direct line that indicates aliens are
responsible. If aliens have and are visiting Earth, they could probably provide answers to many of the great mysteries.
Here is my big problem with alien visitation. Transportation! As easy as Star Trek makes it look, there was a nice segment on warp travel on the
Universe Show a while back and I did significant additional reading. Here are some issues which are pretty sobering:
First, the energy to create a warp drive and bend space is greater than that of a star. Even a star only bends space a little. The super massive
black hole in the center of our galaxy doesn't bend it enough that we are all sucked in. Therefore, the first issue is obtaining and managing
sufficient energy to create a space warp.
Second, even if that could be managed, you would likely need to start the warp drive deep in interstellar space since bending space near your home
planet and your home star would likely destroy them and the entirety of the civilization on the planet. Similarly, if you traveled to close to a star
or planet on the journey, you would also destroy it. Therefore, the ship would need to likely stop in interstellar space as its destination and
somehow travel via another propulsion system to the final planet destination. Therefore, there are huge practical issues with managing a warp ship
even if one can be built and finishing the journey.
Third, the chances of destroying yourself when experimenting with such a vehicle and energy source are high. Therefore, while theoretically possible,
I severely doubt that warp travel has been mastered by anyone, no matter how many millions or billions of years they are ahead of us.
Assuming I am right about the above, that means travel between stars is going to be limited to the nearby neighborhood, 50 - 100 light years. Even
that will take massive amounts of effort and resources. I firmly believe given the number of starts and planets in our galaxy alone, there must be
intelligent life in our galaxy. Carl Sagan once estimated the number of planets in our galaxy with intelligent life to be around 1million, albeit,
that number has been heavily disputed as being too high. Also, what is intelligent? If he is right, there are about 100,000 stars within 100 light
years. that means there is only 1 intelligent civilizations within that 50 - 100 light year radius, i.e. us, statistically. Obviously, a lot a guess
work, but, it shows at least based on some educated guesses how remote the possibility of intelligent alien visitation is.
Ultimately, I think interstellar travel is required for the long term survival of the species as our star will die someday. That is the most
compelling argument that aliens have visited our world. But, given the difficulties I have pointed out above, I don't think it is likely or probable
that aliens do or can regularly visit earth. Rather, they may have passed by once or twice in the last 3 - 5,000 years which has resulted in the
stories in the bible or other legends/myths around the world.
For mankind, I think in the next million years we will develop technology to be able to travel at say 1/2 light speed and be able to send mankind to
stars within 20 light years. In the next 100 years I think most of the planets within 50 light years of the earth will be identified and whether they
have water and are within the goldilocks zone will be determined. There will probably be 50 - 100 of these planets or moons. Ultimately, the planet
may have the resources to send one ship to ten of the most promising worlds within 20 light years or so. These will be one way trips to start mankind
on another world. The chances of success are probably less than 25% per ship. Therefore, in a million years, humankind may exist on 2 or 3 other
worlds in different solar systems.
Finally, I think the most promising technology we are aware of today is quantum entanglement as a communication device. Perhaps that is the true test
of being a technologically superior race, not the ability to master interstellar travel, but, to master interstellar communication. When this is
accomplished, we may find there are some other worlds willing to speak with us that have similar questions and will be able to definitively answer the
question of space travel, aliens and the experience of other world civilizations. I just hope I live long enough to experience that.
To the disclosure fanatics and Steven Greer's of the world, I wanted to believe you, I tried to believe you, but, the evidence simply isn't there.
I have spent the better part of ten years looking and went from a blind believer to a much more critical reader.
