Nov 15, 2023 · 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 ...
Dec 4, 2023 · A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein’s classical concept of spacetime is announced today in two papers published simultaneously by UCL (University College London) physicists. Modern physics is founded upon two pillars: quantum theory on the one hand, which governs the smallest ...
Nov 24, 2015 · Einstein's theory of general relativity describes a broad range of phenomena, from nearly the moment of creation to the end of time, and even a journey spiraling from the deepest space down into a ...
Special relativity also produced the most famous equation ever written: E = mc2. It says that the energy ( E) associated with an object – an atom, a person or a whole galaxy – is equal to its total mass ( m) multiplied by the square of the speed of light (c). As the speed of light is about 300,000 km s -1, this means there is a whole lot of ...
Sep 5, 2013 · Physicists from the Max Planck Institute and the Perimeter Institute in Canada have developed a new approach to the unification of the general theory of relativity and quantum theory. Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal ...
Quantum Gravity and Field Theory. Quantum physics and Einstein’s theory of general relativity are the two solid pillars that underlie much of modern physics. Understanding how these two well-established theories are related remains a central open question in theoretical physics. Over the last several decades, efforts in this direction have ...
Jul 13, 2023 · This inconsistency between Einstein's gravitational theory and modern quantum theory is the reason why ever more precise tests of the equivalence principle are particularly important. A team from ...
