The secrets of the universe have always been one of humanity’s greatest curiosities. However, a new scientific study has revealed that the universe we live in may not be the best place for life. A team led by Dr. Daniele Sorini from Durham University has developed a new model that questions whether our universe really offers the best conditions for life, taking into account factors such as energy density. But is our world as unique as we think?
Our universe may not be the most suitable universe for life! New scientific models offer a different perspective
Researchers have scrutinized the energy density of our universe to understand the conditions that support life. As is known, dark energy, which makes up 70% of the universe, plays a critical role in the expansion of the universe. The developed model calculates the efficiency of star formation based on the amount of dark energy. Interestingly, it was found that in universes with higher amounts of dark energy, star formation can be 27% more efficient. In our universe, it’s 23%.
So far, researchers have studied various universes with different levels of dark energy. Analyses have ranged from universes with completely no dark energy to universes with 100,000 times the dark energy of our universe. The results show that some universes offer a higher probability of life than ours. But the kicker is that our universe’s dark energy density is very close to the level that makes star formation most efficient.
Lead author Dr. Daniele Sorini of Durham University summarizes the research as follows:
“Understanding dark energy and its impact on our universe is one of the biggest challenges in cosmology and fundamental physics. Surprisingly, the parameters governing our universe, including the dark energy density, can explain the existence of even much higher darkness. The energy density may still be compatible with life, suggesting that we may not live in the most likely universe.”
While questioning whether life in our universe is special, the research has also shed new light on popular theories such as the Drake Equation and the Fermi Paradox. While the Drake Equation mathematically evaluates the probability of intelligent life in the universe, the Fermi Paradox questions why we have yet to find these life forms.
In any case, according to the formula proposed by Frank Drake in 1961: “If there were other intelligent forms in other universes, we would have discovered them by now”. Which is a theory that contradicts the Fermi Paradox. In short, although we have not yet found any traces of extraterrestrial life, NASA’s studies of distant star systems may one day help us find answers to these questions. Perhaps in another universe, life is much more common and we are just a tiny dot in our own cosmic corner.
