    Alternatives to general relativity are physical theories that attempt to describe the phenomenon of gravitation in competition with Einstein's theory of general relativity. There have been many different attempts at constructing an ideal theory of gravity. These attempts can be split into four broad categories based on their scope. In this ...

    • Profound implications. Relativity is one of the most famous scientific theories of the 20th century, but how well does it explain the things we see in our daily lives?
    • Electromagnets. Magnetism is a relativistic effect, and if you use electricity you can thank relativity for the fact that generators work at all. If you take a loop of wire and move it through a magnetic field, you generate an electric current.
    • Global Positioning System. In order for your car's GPS navigation to function as accurately as it does, satellites have to take relativistic effects into account.
    • Gold's yellow color. Most metals are shiny because the electrons in the atoms jump from different energy levels, or "orbitals." Some photons that hit the metal get absorbed and re-emitted, though at a longer wavelength.

    Sep 1, 2020 · Abstract. A Review on attempts to propose alternative theories to the General Relativity is presented. The restriction is on classical models/theories and comprise rather algebraic extensions of the theory of General Relativity. First, possible algebraic extensions of the space–time coordinates and metric extensions are presented, with a ...
