Einstein's theory of gravity—general relativity—has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure at spacetime singularities inside black holes—and the Big Bang itself.
According to Einstein, our universe originated in a Big Bang. Other singularities hide inside black holes: Space and time cease to have meaning there, while quantities such as
and pressure become infinite. These signal that Einstein's theory is failing there and must be replaced with a more fundamental one.Quantum physics relies on two simple ideas:make no sense; and the Heisenberg uncertainty principle, which states that one can never know the value of certain pairs of quantities with absolute precision—for example, the position and velocity of a particle.
This is enough to understand that a theory that embraces both general relativity and quantum physics should be free of such pathologies. However, all attempts to blend general relativity andTherefore, Einstein's gravity cannot be the ultimate theory of gravity.
. Here, Λ stands for either Einstein's famous cosmological constant or a mysterious dark energy with similar properties.. Despite fitting cosmological data extremely well until recently, the ΛCDM model is spectacularly incomplete and unsatisfactory from the theoretical point of view..
