“Early Mars was Habitable –But Was It Inhabited?” –An Ancient Global Megaflood Hints ‘Yes’

"Early Mars was Habitable --But Was it inhabited?" --An Ancient Global Megaflood Hints 'Yes'

 

“Early Mars was an extremely active planet from a geological point of view,” said Alberto G. Fairén, a visiting astrobiologist at Cornell University. “The planet had the conditions needed to support the presence of liquid water on the surface – and on Earth, where there’s water, there’s life. “So early Mars was a habitable planet,” he said. “Was it inhabited? That’s a question that the next rover Perseverance will help to answer.”

“It’s worthwhile to not just do what was done 60 years ago, but also to keep an eye out for very unusual things,” says SETI Institute astronomer Seth Shostak. “The universe has been around for three times as long as the Earth has been around, so there could be aliens out there that are very, very much more advanced than we are—not just 1,000 years, but millions and billions of years ahead.”

Unanswered –“Can Life in the Universe Be Explained By Physics?”

“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.

“Our Original Sun was a Supernova” –Has the Phenomenon Effected Earth’s Evolution and Climate?

Vela Supernova

 

“Although Earth was originally created from the Sun (as part of the ecliptic plane of debris and dust that circulated around the Sun 4.5 billion years ago), our Sun is barely hot enough to fuse hydrogen to helium, observed physicist Michio Kaku in Parallel Worlds: A Journey through Creation, Higher Dimensions, and the Future of the Cosmos. “This means that our true “mother” sun was actually an unnamed star or collection of stars that died billions of years ago in a supernova, which then seeded nearby nebulae with the higher elements beyond iron that make up our body. Literally, our bodies are made of stardust, from stars that died billions of years ago.”

“Enigma” –The 120-Mile-High Plumes of Europa’s Global Ocean

The Mystery of Europa's Mile-High Plumes --"Harbor Signs of Life, or Something Else?"

 

With a layered inner structure including a liquid iron core, a thin oxygen-rich atmosphere, an ice-shrouded global ocean with surface plumes that may spew signs of life, and an induced magnetic field—Jupiter’s fourth largest moon, Europa, has greater resemblance to a planet than a gas-giant’s moon.
