Background independence is a condition in theoretical physics that requires the defining equations of a theory to be independent of the actual shape of the spacetime and the value of various fields within the spacetime.
Q & A with Dejan Vinkovic illustrated with a few pictures and a GIF animation of a self-creating universe, in which Gott advocates the importance of the average person having an education in science and especially physics. Abstract to Gott's "A grim reckoning" New Scientist article - online content of the full article requires a paid registration.
The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [1] The notion of an expanding universe was first scientifically originated by physicist Alexander Friedmann in 1922 with the mathematical derivation of the Friedmann equations.
In physics, the principle of relativity is the requirement that the equations describing the laws of physics have the same form in all admissible frames of reference.. For example, in the framework of special relativity, the Maxwell equations have the same form in all inertial frames of reference.
The God Equation: The Quest for a Theory of Everything is a popular science book by the futurist and physicist Michio Kaku. The book was initially published on April 6, 2021, by Doubleday. [1] [2] The book debuted at number six on The New York Times nonfiction best-seller list for the week ending April 10, 2021. [3]
Mathematical physicist Frank Tipler generalized [13] Teilhard's term Omega Point to describe what he alleges is the ultimate fate of the universe as required by the laws of physics: roughly, Tipler argues that quantum mechanics is inconsistent unless the future of every point in spacetime contains an intelligent observer to collapse the ...
At present, there is no candidate theory of everything that includes the standard model of particle physics and general relativity and that, at the same time, is able to calculate the fine-structure constant or the mass of the electron. [2]
a particular multiverse with a "measure", i.e. a well defined "density of universes" (so, for parameter X, one can calculate the prior probability P(X 0) dX that X is in the range X 0 < X < X 0 + dX), and; an estimate of the number of observers in each universe, N(X) (e.g., this might be taken as proportional to the number of stars in the ...
