If the universe is sooooo huge, aliens must exist.
What do you think? Is there such a thing as aliens? Or should they be lumped in the same category as ghosts and goblins and orcs?
Mainstream Scientist Michio Kaku Believes In Existence of Extraterrestrial Civilizations. He Lays Down a Hypothesis in Many of His Books.
Michio Kaku is a well respected theoretical physicist who graduated from Harvard in 1968 and has made notable contributions to string theory. While it is the belief by many that mainstream scientists reject any notions of extraterrestrial civilizations or aliens, Kaku is very unique. Not only does he believe in ETs, he also lays down a framework for their existence in his numerous books.
I have read Kaku's work, and he makes a convincing argument for the probability of alien civilizations. In his book Hyperspace, Kaku points out that there are at least hundreds of thousands of galaxies in the universe, which contain hundreds of thousands of planets. The probability is very high that not only do a few alien civilizations exist, but many. Kaku in his book Hyperspace compares humans as fish in a pond, only aware of the environment around them, not realizing there is a huge world outside the pond. In an article at his website Kaku had this to say In regards to Carl Sagan, another believer in alien civilizations:
the late Carl Sagan once asked this question, What does it mean for a civilization to be a million years old? We have had radio telescopes and spaceships for a few decades; our technical civilization is a few hundred years old... an advanced civilization millions of years old is as much beyond us as we are beyond a bush baby or a macaque.
This answers the question that many debunkers have raised for years. For years they have asked why aliens don't just announce their presence, or land in Times Square.
The reason that they will not do this is because if you are dealing with beings that are tens of thousands of years ahead of us, even millions, they would not be interested in us. Are you interested in an ant while you walk down the street?
Would you try to explain to a dog how to perform a complex equation? Most likely you would not, because a dog would not be capable of comprehending it. Now imagine an advanced civilization that are thousands of years ahead of us. See my point?
Kaku lays down a framework of levels of civilizations. Type 1, Type 2, and Type 3. Here are the descriptions of a civilization at these three levels:
Physics of Type I, II, and III Civilizations
Specifically, we can rank civilizations by their energy consumption, using the following principles:
1) The laws of thermodynamics. Even an advanced civilization is bound by the laws of thermodynamics, especially the Second Law, and can hence be ranked by the energy at their disposal.
2) The laws of stable matter. Baryonic matter (e.g. based on protons and neutrons) tends to clump into three large groupings: planets, stars and galaxies. (This is a well-defined by product of stellar and galactic evolution, thermonuclear fusion, etc.) Thus, their energy will also be based on three distinct types, and this places upper limits on their rate of energy consumption.
3) The laws of planetary evolution. Any advanced civilization must grow in energy consumption faster than the frequency of life-threatening catastrophes (e.g. meteor impacts, ice ages, supernovas, etc.). If they grow any slower, they are doomed to extinction. This places mathematical lower limits on the rate of growth of these civilizations.
Kaku defines a Type 1 civilization as one that is truly a planetary society, who has mastered all forms of terrestrial energy. Their energy output is much greater than ours. It would take at least 3,200 years to reach Type 2.
A Type 2 civilization is a civilization who have an energy output of a small star. They would be so advanced that they could build a sphere around their planet to maximize their energy output.
A Type 3 civilization is so advanced that they have begun colonizing other star systems. Their energy output is massive compared to ours. A civilization this advanced would be able to bend space and time at will. They would probably be capable of interdimensional travel and even time travel.
So where are we here on planet Earth? Well, we are type zero. We still get our energy from dead plants. Pretty pathetic, if you ask me. I could only imagine what an advanced alien civilizations thinks of us. With our racism, wars, and class struggles we will be luck if we ever get to a Type 1. At the current rate, in my opinion the human race is headed toward extinction. To read articles about Micho Kaku click the links below.
