Scientists say dinosaurs still exist on other planets
Dinosaurs may have been extinct more than 65 million years ago, but scientists suggest they still exist as aliens on other planets.
Research published in the Monthly Notices of the Royal Astronomical Society suggests that dinosaurs may not only exist on other planets, but we can find them, too.
The study indicates that if scientists search for compounds that do not currently exist on Earth but were present during the age of dinosaurs, they may yield some results.
One key element that scientists believe could unlock what could be a groundbreaking discovery is oxygen. Oxygen levels on Earth today are about 21%, but in the time of the dinosaurs they were 30% higher. This, in theory, allowed dinosaurs to flourish and dominate the planet for millions of years.
The study suggests that if similar levels of oxygen can be detected on distant planets, conditions may be suitable for the existence of alien life such as dinosaurs.
“The optical fingerprint of modern Earth has been our model for identifying potentially habitable planets, but there was a time when this fingerprint was clearer — better at showing signs of life,” Lisa Kaltenegger, a co-author of the study, said in a statement.
“This gives us hope that it might be a little easier to find signs of life — even large, complex life — elsewhere in the universe,” she adds.
One clue that could unlock this discovery that scientists are searching for is signs of a Phanerozoic stage on a planet that would have allowed creatures like dinosaurs to evolve.
The study’s lead author, Rebecca Payne of Cornell University, said: “The Phanerozoic is the latest 12% or so of Earth’s history, but it includes almost all the time when life was more complex than microbes and sponges. Light fingerprints are what you’re looking for.” “Where else if you’re looking for something more advanced than a single-celled organism.”
If they succeed in finding these conditions on other planets, Kaltenegger believes it could lead to the discovery of dinosaurs that have never been found on Earth before.
“We hope to find some planets that have more oxygen than Earth right now because that will make the search for life a little easier,” she said. “And who knows, maybe there are other dinosaurs waiting to be found.”
