The Physics of COVID-19 –“People are Like Galaxies”


The Physics of Covid-19


Some of the greatest medical discoveries of the 20th century came from physicists who switched careers and became biologists. Francis Crick, who won the 1962 Nobel Prize in Physiology and helped identify the structure of DNA, started his career as a physicist, as did Leo Szilard who conceived the nuclear chain reaction in 1933, writing the letter for Albert Einstein’s signature that resulted in the Manhattan Project that built the atomic bomb, but spent the last decades of his life doing pioneering work in biology, including the first cloning of a human cell.

“If you look at the entire physical cosmos, our brains are a tiny, tiny part of it. But they’re the most perfectly organized part.” says Noble-Prize winner, physicist Sir Roger Penrose, comparing the complexity of the universe to the human brain with its cerebral cortex, the folded gray matter that covers the first couple of millimeters of the outer brain like wrapping paper, where “matter is transformed into the mystery of consciousness.” (more…)

“One can best feel in dealing with living things how primitive physics still is,” said Albert Einstein. “Can life be explained in terms of physics or will it always be a mystery? And if physics can explain life, is existing physics up to the job, or might it require something fundamentally new – new concepts, new laws even?” asks Arizona State University cosmologist, theoretical physicist, and astrobiologist, Paul Davies answering Einstein.

Life is incredibly resilient. In April, 2019, a microscopic, multicellular species, also known as the water bear, likely made it out alive following a crash landing on the Moon’s surface by Israel’s Beresheet probe. Based on an analysis of the spacecraft’s trajectory and the composition of the device the micro-animals were stored in the chances of survival for the tardigrades… are extremely high,” reported AFP, adding that the diminutive creatures, which are under a millimeter (0.04 inches) in size, had been dehydrated to place them in suspended animation, then “encased in an epoxy of artificial amber, and should be revivable in the future.”

“Any extraterrestrial organisms we find will be made of the same atoms we are,” observes Harvard’s Center for Astrophysics, Avi Loeb, about the recent detection of a potential biosignature in the atmosphere of Venus, the nearest planet to Earth where NASA is currently considering sending a spacecraft.

“So they’re kind of like dark matter,” said paleontologist David Jablonski of the University of Chicago about the sanctuaries, the “refugia” that have never been found in the fossil record, but sheltered the shell-shocked and decimated species of Earth’s past mass extinctions until they were able to repopulate the planet in ensuing eons.
