Life on earth has been considered mysteries in so many ways for so long.
The Physics of Extraterrestrial Civilizations How advanced could they possibly be? 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.
In particular, now that the laws of quantum field theory, general relativity, thermodynamics, etc. This question is no longer a matter of idle speculation. Soon, humanity may face an existential shock as the current list of a dozen Jupiter-sized extra-solar planets swells to hundreds of earth-sized planets, almost identical twins of our celestial homeland.
This may usher in a new era in our relationship with the universe: Today, every few weeks brings news of a new Jupiter-sized extra-solar planet being discovered, the latest being about 15 light years away orbiting around the star Gliese The most spectacular of these findings was photographed by the Hubble Space Telescope, which captured breathtaking photos of a planet light years away being sling-shot into space by a double-star system.
But the best is yet to come. Early in the next decade, scientists will launch a new kind of telescope, the interferome try space telescope, which uses the interference of light beams to enhance the resolving power of telescopes.
For example, the Space Interferometry Mission SIMto be launched early in the next decade, consists of multiple telescopes placed along Search for extraterrestrial life essay example 30 foot structure.
With an unprecedented resolution approaching the physical limits of optics, the SIM is so sensitive that it almost defies belief: The SIM, in turn, will pave the way for the Terrestrial Planet Finder, to be launched late in the next decade, which should identify even more earth-like planets.
It will scan the brightest 1, stars within 50 light years of the earth and will focus on the 50 to brightest planetary systems. All this, in turn, will stimulate an active effort to determine if any of them harbor life, perhaps some with civilizations more advanced than ours. Although it is impossible to predict the precise features of such advanced civilizations, their broad outlines can be analyzed using the laws of physics.
No matter how many millions of years separate us from them, they still must obey the iron laws of physics, which are now advanced enough to explain everything from sub-atomic particles to the large-scale structure of the universe, through a staggering 43 orders of magnitude.
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. 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.
Any advanced civilization must grow in energy consumption faster than the frequency of life-threatening catastrophes e. If they grow any slower, they are doomed to extinction. This places mathematical lower limits on the rate of growth of these civilizations.
In a seminal paper published in in the Journal of Soviet Astronomy, Russian astrophysicist Nicolai Kardashev theorized that advanced civilizations must therefore be grouped according to three types: He calculated that the energy consumption of these three types of civilization would be separated by a factor of many billions.
Shorter than most realize. Berkeley astronomer Don Goldsmith reminds us that the earth receives about one billionth of the suns energy, and that humans utilize about one millionth of that.
So we consume about one million billionth of the suns total energy. At present, our entire planetary energy production is about 10 billion billion ergs per second. But our energy growth is rising exponentially, and hence we can calculate how long it will take to rise to Type II or III status.
Their energy output may be on the order of thousands to millions of times our current planetary output. They also have enough energy to alter the course of earthquakes, volcanoes, and build cities on their oceans.
Currently, our energy output qualifies us for Type 0 status. We derive our energy not from harnessing global forces, but by burning dead plants e. But already, we can see the seeds of a Type I civilization. We see the beginning of a planetary language Englisha planetary communication system the Interneta planetary economy the forging of the European Unionand even the beginnings of a planetary culture via mass media, TV, rock music, and Hollywood films.
By definition, an advanced civilization must grow faster than the frequency of life-threatening catastrophes. Since large meteor and comet impacts take place once every few thousand years, a Type I civilization must master space travel to deflect space debris within that time frame, which should not be much of a problem.
Ice ages may take place on a time scale of tens of thousands of years, so a Type I civilization must learn to modify the weather within that time frame. Artificial and internal catastrophes must also be negotiated.
But the problem of global pollution is only a mortal threat for a Type 0 civilization; a Type I civilization has lived for several millennia as a planetary civilization, necessarily achieving ecological planetary balance.
Internal problems like wars do pose a serious recurring threat, but they have thousands of years in which to solve racial, national, and sectarian conflicts.
Eventually, after several thousand years, a Type I civilization will exhaust the power of a planet, and will derive their energy by consuming the entire output of their suns energy, or roughly a billion trillion trillion ergs per second.
With their energy output comparable to that of a small star, they should be visible from space. Dyson has proposed that a Type II civilization may even build a gigantic sphere around their star to more efficiently utilize its total energy output.The Search for Extraterrestrial Life Essay Words | 8 Pages Abstract: Scientists claim that other life forms do in fact exist based on probability.
