Life was present even before the creation of Earth – Moore’s law research shows
Researchers have hypothesized that life existed even before the Earth came into being. They used the Moore’s law – a classical saying from the computer industry – to estimate the findings.
Moore’s law is the prediction by Intel cofounder Gordon Moore in the early days of the computer revolution about the growth of semiconductor technology.
He predicted that the number of transistors that could be put on a chip would double every year, and it did. Ten years later, Moore predicted that chip capacity would double every two years, and capacity has actually doubled every 18 months since then. The doubling of capacity every 18 months is popularly called a “law.”
Based on this law, two scientists; Alexei Sharov of the National Institute on Aging in Baltimore, and Richard Gordon of the Gulf Specimen Marine Laboratory in Florida, calculated the rate at which the life on Earth grows into complexity revealing the existence of organic life long before the presence of Earth itself.
In order to parallelize the computational thinking with the biological mind, they replaced the transistors with the nucleotides, which are the building blocks of DNA and RNA, and the circuits with genetic material and calculated the rest. They found that the life came into being nearly 10 billion years ago while the age of the Earth is less than half of that i.e. 4.5 billion years.
“Linear regression of genetic complexity (on a log scale) extrapolated back to just one base pair suggests the time of the origin of life = 9.7 ± 2.5 billion years ago,” Scientists said.
According to Sharov and Gordon, tiny organisms might be created somewhere in the universe and later came to the Earth.
“Contamination with bacterial spores from space appears the most plausible hypothesis that explains the early appearance of life on Earth,” scientists concluded in their finding.
Sharov stated that “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.”
