How does a supernova affect humans?

Answer 1

A supernova depletes the ozone layer, exposing humans to radiation.

Just to be clear, in order for the supernova to deplete the ozone layer, the supernova would have to be 33 light years away or less from the Earth. These are called Near-Earth Supernovas. On average, a supernova like this occurs once every 240 million years.

The gamma rays caused by this supernova would reach the upper atmosphere. Here, a chemical reaction occurs where the molecular nitrogen turns into nitrogen oxides. This in turn depletes the ozone layer, exposing humans to solar and cosmic radiation.

Answer 2

A nearby supernova could potentially cause harm to humans through increased radiation exposure, which could result in health problems like radiation sickness and an increased risk of cancer. The shockwave from the supernova could also affect Earth's atmosphere, which could lead to changes in climate and weather patterns. Nevertheless, the chances of a supernova causing significant harm to humans are low because of the great distances that separate Earth and potential supernova events.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
