How likely is technologically advanced life elsewhere in the Universe?

  • Mon 13th Jun 2022

We live in a universe perfectly suited to our existence. We are discovering ever more exoplanets and the molecular building blocks of life. On Earth, simple life is found in rocks, ice and boiling water, suggesting it would be impossible to destroy, before the Sun becomes a red giant. Yet space is silent, suggesting, that though simple life may be common, technologically advanced life might be very rare. We will review the current thinking.
