UV Radiation Spikes

TNRTB Archive - Retained for reference information

Astronomers have discovered a new design feature for advanced life on Earth. Survival of advanced life requires avoidance of deadly ultraviolet radiation spikes in the local interstellar medium as a consequence of the birth of a nearby association of giant stars. The spikes, which last about 30 million years, occur about once every billion years or so, while shorter spikes lasting a hundred thousand years or so occur much more frequently as a result of individual giant stars “running away” from their associations. Humanity’s entrance into cosmic history at the just-right time seems no accident of evolution.
