“We proved that the Einstein field equation from general relativity is actually a relativistic quantum mechanical equation,” ...

The Einstein field equations are a system of second order, non-linear, coupled differential equations in 4 variables. As you can imagine, solving such a system is not easy. If the system possesses a ...

The result of Einstein's thinking about light, this theory introduced brand-new ideas to science. It opened up an entire field of physics, but left Einstein with some nagging questions.
