How big can a star get? This is a calculation made by one of the
original pioneers of modern astronomy, Sir Arthur Eddington. And
it’s named after him, the Eddington Limit. Now, astronomers are
finding examples of giant black holes early in the Universe,
calling into question some of Eddington’s assumptions. Let’s
explore this fascinating concept! Why are stars sphere-ish? Why
do blackholes not eat everything? Why do pulsating stars pulsate?
It all comes down to work done by Eddington at the beginning of
the last century, and today we're going to look back at
Eddington's work and all its applications in modern Astronomy.
