Is there really life out there in space? This scientist thinks it existed closer than we think. As in, right here, in our own solar system. Extraterrestrials may have harbored and lived on a planet within our vicinity, even our own planet Earth.
Astrophysicist, Jason T. Wright believes that aliens lived on our surrounding planets before vanishing forever.
He speculates that the life forms existed millions of years ago.
How does one look for signs of life in outer space? Biosignatures.
How does one look for remnants of technology? Technosignatures.
Instead of looking for life, Wright is looking for technology that is “designed by life.”
He gives examples like radio towers, or The Empire State Building.
