A new paper by Staff Scientist Alexei Sharov, of the National Institute on Aging in Baltimore, and Theoretical Biologist Richard Gordon, of the Gulf Specimen Marine Laboratory in Florida, took Moore’s Law and applied it to the complexity in which life on Earth grows to come up with a surprising theory.
Moore’s Law is the observation that technology increases exponentially in complexity at a predicable rate of double the transistors per integrated circuit every couple of years. Using the law and working backward from the last few years of computational complexity, you will get back to the 1960’s, which was when the first microchip was invented.
Sharov and Gordon, using this same standard with the complexity of life, where able to come to the conclusion that life came into existence long before the Earth itself. About 5.5 billion years before the Earth.
So even if it’s mathematically possible for life to have existed before Earth did, is it physically possible? Again, Sharov and Gordon said yes, it is. As our solar system was forming, pre-existing bacteria-like organisms, or even simple nucleotides from an older part of the galaxy, could have reached Earth by hitching an interstellar ride on comets, asteroids or other inorganic space debris — a theoretical process called panspermia
Now there is no way for the scientist to know with certainty that organic complexity increased at a stable rate throughout the history of the universe, so they prefer to call the paper a “thought exercise or essay” according to Sharov.
One of the more interesting conclusions from this research is that it goes to debunk the idea of advanced alien life on another world, since all life would develop at the same rate. What you would find would be aliens who are just as developed as humans in terms of knowledge and ability.
Although some may be skeptical of Sharov and Gordon’s findings, the scientists stand by their conclusions. “Contamination with bacterial spores from space appears the most plausible hypothesis that explains the early appearance of life on Earth,” they argue in the paper, which is published online in the preprint journal Arxiv.
Sharov said that if he had to bet on it, he’d say “it’s 99 percent true that life started before Earth — but we should leave 1 percent for some wild chance that we haven’t accounted for.”
This comes at the same time that Stephen Hawking declares that the Big Bang did not need a god, but that is nothing new. In his April 16th lecture, Hawking explained how theories about the universe having no beginning or end do not stand up as observations go to show that there was only one big bang. According to Hawking, time began at the moment of singularity and it is likely that this has only occurred once. If he is correct, this puts the age of the universe at 13.8 billion years, which is only 3.8 billion years before life began.
Hawking closed by outlining his “M-theory” which states that multiple universes are created out of nothing, with many possible histories and many possible states of existence. In only a few of these states would life be possible and even fewer in which human type life could exist.
Now I know there will be those who disagree with me, but I look at this as more proof towards creation than random and uncontrolled evolution from bacteria.
