In the book ‘A BRIEF HISTORY OF TIME’ by Stephen Hawking explains about existence of super-intelligent human species, stating “One can answer this on the basis of the weak anthropic principle. Conditions in the contracting phase would not be suitable for the existence of intelligent beings who could ask the questions: Why is disorder increasing in the same direction of time as that in which the universe is expanding? The inflation in the early stages of the universe, which the no boundary proposal predicts, means that the universe must be expanding at very close to the critical rate at which it would just avoid recollapse, and so will not recollapse for a very long time. By then all the stars will have burned out and the protons and neutrons in them will probably have decayed into light particles and radiation. The universe would be in a state of almost complete disorder. There would be no strong thermodynamic arrow of time. Disorder couldn’t increase much because the universe would be in a state of almost complete disorder already. However, a strong thermodynamic arrow is necessary for intelligent life to operate. Thus life could not exist in the contracting phase of the universe.”
Coming down to Earth’s system; the entropy physics also applies same here. The “law of conservation of Energy” may remain constant; however, it is not going to save the biota of the Earth ultimately. It is because the second law of thermodynamics which states that the entropy of the Universe keeps on increasing incessantly with time. One of the most brilliant scientific minds since Einstein, the Stephan Hawking, expresses former as “This radiation is required in order to prevent violation of the second law.” What would be fate of the extant biota, especially the super-intelligent ‘Human Beings’ of this Earth, which needs constant supply of low entropy system?
If the increasing entropy system were to continue on Earth without “Auto-Recharge System”, the biological world would have been eradicated very long time back. The law of physics on earth has been set by God in such a state that constantly “Auto-Recharge Mechanism” which will recover the entropy systems like biogeochemical cycles. The earth acts both as open and closed systems. The earth’s mechanical system cannot perform completely the closed system without acting as open system. The insolation to the Earth as an open system, has been operating to construct the complete biological structural world. Since industrialization in 1850s, the rapidly increasing entropy on earth due to anthropogenic activities can, therefore, be reversed and its climate can be controlled and managed. We may not control the entropy of the Universe, but, we can do to Earth planet. Ultimately, the entropy state is going to determine the extant life on Earth.
The climate change on Earth is not a new topic now. It can have both positive and negative impact on entropy. In case of huge melting the glaciers, ice lands on earth i.e. the increasing entropy, has the negative impacts. How can this Science and Technology can manipulate this working system of this earth in order to keep or lessen its entropy level. Had there been in Mars ever a Climate Change that might have completely eradicated the sustenance of life forms i.e. collapse of the auto-recharge mechanism? It can only be come out of shadow after discovery of biosignatures on Mars river terrains sunlight never reaches–at dark ocean depths, inside rocks, and deep below the surface; the search is on by NASA.
Like Earth, Mars has valleys that seem to be caused by a flowing fluid, presumably water. One can see dendritic drainage patterns as well as flood channels on the Martian surface. This module focuses on whether the channels observed on Mars are evidence of great floods and, if so, on how Pathfinder helps scientists to use the debris from such floods to obtain information about four billion years of Martian geologic history. In addition to liquid water, life also needs energy. Therefore, future missions will also be on the lookout for energy sources other than sunlight, since life on the surface of mars is unlikely given the presence of “superoxides” that break down organic (carbon-based) molecules on which life is based. On Earth, all forms of life need water to survive. It is likely, though not certain, that if life ever evolved on Mars, it did so in the presence of a long-standing supply of water. On Mars, we will therefore search for evidence of life in areas where liquid water was once stable, and below the surface where it still might exist today. Perhaps there might also be some current “hot spots” on Mars where hydrothermal pools (like those at Yellowstone) provide places for life. Recent data from Mars Global Surveyor suggest that liquid water may exist just below the surface in rare places on the planet, and the 2001 Mars Odyssey will be mapping subsurface water reservoirs on a global scale. We know that water ice is present at the Martian poles, and these areas will be good places to search for evidence of life as well.
Like on Earth in Mars, were there such an auto-recharge mechanism. Scientists are looking if this system still exists on Mars, our supposed next spaceship because we have not yet invented spaceship that travels in a Light Years to reach far across galaxies to search, discover, reach and live in another planetary system alike to earth’s system in this Universe.
