“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 singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

A new model has been proposed that challenges the long-standing belief that black holes contain a singularity, a region where space and time break down. This theory suggests that black holes could ...

The article holds special importance for research in the field of energy as we now ... He further added, "We learned from ...

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.

All of this is calculated with the equations that underpin general relativity: Einstein's field equations. "The way that the space-time curves is determined by the Einstein field equations ...
