Are humans alone in the Universe?

We are, according to this report, Dissolving the Fermi Paradox, published earlier this month.

It’s not surprising that we haven’t found anyone who is like us. Life on the surface of a planet is precarious – the constantly changing atmosphere has to stay within certain boundaries for us to survive. The magnetism that deflects most of the solar wind,which would otherwise strip away the ozone layer that protects Earth from harmful ultraviolet radiation is always fluctuating. Then there’s the ever-constant threat of asteroids.

Anything that survives on the surface has to be adaptable and somewhat vicious. This suited humanity in the short run (the past 200,000 years, an eye-blink in universal time), but when our adaptability gives us the power to destroy the planet, it puts us at a tipping point; expand to other planets or die here.

Other surface dwellers may have reached this point, and may not have survived. Or, they could have evolved into something that’s so advanced, we can’t even comprehend their existence.
