Although the first known interstellar object to pass through our Solar System has long since passed beyond our reach, the Harvard astrophysicist that first proposed that ʻOumuamua might have been an artificial object built by an extraterrestrial civilization has expanded on the concept. In an interview with Salon magazine about his new
A recent analysis of the fossils of ancient microorganisms from deep within Earth’s past have unveiled the presence of a surprising amount of biodiversity that flourished roughly 3.4 billion years ago, when the Earth was still a very young planet. The variety of metabolic processes that these early microorganisms used suggests that they needed time to evolve the diversity that the researchers discovered, meaning that life on Earth had to have started much, much earlier. And if life on Earth took hold that quickly in its history, what would prevent the multitude of other planets we’re discovering across the universe from forming their own lifeforms?
Researchers may have discovered direct evidence of a former sister planet that resided in our Solar System, but was obliterated during an unknown cataclysm that occurred billions of years ago. It is theorized that the Solar System may have had as many as ten such lost planets early in its history, but this new evidence takes such theories and brings them that much closer to reality.
