How about this? “Reconciliation of general relativity with the laws of quantum physics remains a problem, however, as there is a lack of a self-consistent theory of quantum gravity. It not yet known how gravity can be unified with the three non-gravitational forces—strong, weak, and electromagnetic forces.”.
For 100 years, the general theory of relativity has been a pillar of modern physics. The basic idea is so elegant that you don’t need superpowers to understand it. Begin with Isaac Newton’s first law of motion: An object remains in uniform motion unless acted on by a force.
一般相対性理論 （いっぱんそうたいせいりろん、 独: allgemeine Relativitätstheorie, 英: general theory of relativity ）は、 アルベルト・アインシュタイン が 1905年 の 特殊相対性理論 に続いて、それを発展させ 1915年 から 1916年 にかけて発表した 物理学 の理論である ...
General relativity. General relativity ek theory hae space aur time ke baare me jiske Albert Einstein banais rahaa aur 1915 me publish karis rahaa. Ii vigyan article ek chhota panna hae. Aap iske lamba karke Wikipedia ke madat kare saktaa hae.
Palatini variation. In general relativity and gravitation the Palatini variation is nowadays thought of as a variation of a Lagrangian with respect to the connection. In fact, as is well known, the Einstein–Hilbert action for general relativity was first formulated purely in terms of the spacetime metric . In the Palatini variational method ...
The Friedmann–Lemaître–Robertson–Walker metric ( FLRW; / ˈfriːdmən ləˈmɛtrə ... /) is a metric based on an exact solution of the Einstein field equations of general relativity. The metric describes a homogeneous, isotropic, expanding (or otherwise, contracting) universe that is path-connected, but not necessarily simply connected.
