“The Radio Species” –Scientists Doubt ‘Human Niche’ Would Be Filled If We Go Extinct

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?”

“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.”

“The Galaxy With One Star” –A Profound Puzzle for Physics

 

Black Hole

 

“If this monster was at the center of the Milky Way it would likely make life on Earth impossible with the huge amounts of x-rays emanating from it,” said Christian Wolf, with the Australian National University (ANU) Research School of Astronomy and Astrophysics who made the momentous detection in 2018. “It would appear 10 times brighter than a full moon, an incredibly bright pin-point star that would almost wash out all of the stars in the sky. It’s probably 10,000 times brighter than the galaxy it lives in.” So bright, that it if we were approaching the galaxy in a starship, the object would so blind our view that  we could not see the galaxy itself.
