The Fermi Paradox ask us how in a Universe so vast and ancient we seem to be the only intelligent civilization around, with no older interstellar alien empires visible in the galaxy. But could extinction play a role in that, or might extinction events instead drive evolution forward?

There are likely many exciting alien worlds for extraterrestrials to visit.
Now that more and more scientists are actively searching for signs of extraterrestrial life, whether in our solar system or in the far reaches of space, more attention has been brought to the Fermi paradox.
A new study in preprint server arXiv suggests that we might not have encountered intelligent extraterrestrials because they may not find humanity very interesting.
According to a recent paper by a math professor at the University of Arkansas, the existence of life on Earth provides proof that abiogenesis is relatively easy on planets similar to Earth, refuting the “Carter argument” conclusion.
Does the presence of life on Earth provide any insight into the likelihood that abiogenesis—the process by which life first emerges from inorganic substances—occurs elsewhere? That is a question that has baffled scientists for a while, as well as everyone else inclined to think about it.

Are alien civilizations likely to be younger or older than us in age? A basic question that seems insurmountable until we start detecting them. But even before that, we can use some logical deduction using lifetime distribution statistics to determine the most plausible answer to this question. Join us today for an explanation of our new research paper on this topic.

If we re-ran Earth’s clock, would life arise again? Would another civilization eventually evolve? Astrobiology is faced with trying to contextualize our place in the Universe using just a single data point. But even a single data point contains information. The key to unlocking it is a careful understanding of the selection biases at play and intricacies of Bayesian statistics. Today, we’re thrilled to present to you our explainer video of a new research paper led by Prof David Kipping that provides a direct quantification of the odds of life and intelligence on Earth-like worlds, based on our own chronology. Presented & Written by Prof. David Kipping.
