This video is about how Albert Einstein made a mistake when applying the Field Equations of General Relativity to cosmology (in particular, to a static, constant density universe), and solved the problem by introducing the cosmological constant, rather than allowing for a dynamic universe with a scale factor - that is, the Friedmann-Lemaitre-Robertson-Walker universe, first developed by Alexander Friedmann of Russia. Later, it was discovered by the Slipher and Hubble red-shift that the universe is indeed expanding, and even later, by Schwarz and company in 1998, that the expansion is accelerating - aka, dark energy. And the cosmological constant was re-introduced.

Ayush ShuklaA bit more on it:

6 months ago (edited) | [YT] | 143The constant that Einstein added has had an effect on findings related to dark energy.

I read it somewhere:

Einstein's two biggest mistakes were:

Adding that constant

Removing that constant
