The Jeans mass is named after the British physicist Sir James Jeans, who considered the process of gravitational collapse within a gaseous cloud. He was able to show that, under appropriate conditions, a cloud, or part of one, would become unstable and begin to collapse when it lacked sufficient gaseous pressure support to balance the force of gravity.
Jeans came up with another version of this equation, called Jeans mass or Jeans instability, that solves for the critical mass a cloud must attain before being able to collapse. Jeans also helped to discover the Rayleigh–Jeans law, which relates the energy density of black-body radiation to the temperature of the emission source.

The book was denounced by the Cambridge philosopher Ludwig Wittgenstein, because "Jeans has written a book called The Mysterious Universe and I loathe it and call it misleading. Take the title...I might say that the title The Mysterious Universe includes a kind of idol worship, the idol being Science and the Scientist."
