For what purpose did the human brain evolve is a question that has puzzled scientists for decades.In 2010 Colin Blakemore, an Oxford neurobiologist argued that a mutation in the brain of a single human being 200,000 years ago turned intellectually able primates into a super-intelligent species that would conquer the world. Homo sapiens appears to be a genetic accident.

Stephen Hawking’s Great Question –“Why Isn’t the Milky Way Crawling With Mechanical or Biological Life?”

“If the argument about the time scale for the appearance of life on Earth is correct”, Stephen Hawking observed, echoing Enrico Fermi’s infamous question–Where is Everybody– “there ought to be many other stars, whose planets have life on them. Some of these stellar systems could have formed 5 billion years before the Earth. So why is the galaxy not crawling with self-designing mechanical or biological life forms?”

“First In, Last Out” –A Dark Solution to the Fermi Paradox

 

Very Large Telescope

 

Some scientists have suggested that in our anxious search for the answer to the Fermi Paradox –“are we alone in the cosmos”–we’re searching for intelligent, conscious, tool-making beings that have developed a language we’re capable of understanding, we are, in fact, searching for ourselves .

“Liftoff!” –NASA’s Ingenuity Helicopter to Forever Change the Way We Explore Other Planets

 

 Ingenuity Mars Helicopter

 

NASA’s announced the first instance of powered, controlled flight on another planet when the solar-powered “Ingenuity Mars Helicopter first became airborne at 3:34 a.m. EDT (12:34 a.m. PDT) – 12:33 – a time the Ingenuity team determined would have optimal energy and flight conditions. Altimeter data indicate Ingenuity climbed to its prescribed maximum altitude of 10 feet (3 meters) and maintained a stable hover for 30 seconds. It then descended, touching back down on the surface of Mars after logging a total of 39.1 seconds of flight. Additional details on the test are expected in upcoming downlinks.”

“Without phosphorus there would be no thought,” observed Jacob Moleschott a 19th-century physiologist and philosopher. Phosphorus is one of the six main elements that make up the human body and an essential element for life as we know it for the creation of DNA, cell membranes, bones and teeth in humans, and even the microbiome of ocean-dwelling plankton–as a possible signature in the search for life in the cosmos.
