Are there alternate theories to gravity?

The best-known alternative gravity theories are known as modified Newtonian dynamics, commonly abbreviated to MOND. MOND-type theories attempt to do away with dark matter by tweaking our definition of gravity.

What are the theories of gravity?

Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as a consequence of masses moving along geodesic lines in a curved spacetime caused by the uneven distribution of mass.

What is alternative theory?

(thē′ə-rē, thîr′ē) pl. the·o·ries. 1. A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena.

What is the new theory of gravity?

Entropic gravity, also known as emergent gravity, is a theory in modern physics that describes gravity as an entropic force—a force with macro-scale homogeneity but which is subject to quantum-level disorder—and not a fundamental interaction.

What is the PAN theory of gravity?

The Pan Theory explains gravity and magnetism by a simple, physical field theory. And the strong and weak interactions are explained by way of mechanical nuclear connections. Instead, the Pan theory proposes background-field density and flow differences to explain Einstein’s warped space proposal.

What is an example of alternative theory?

The alternative theory, that the brain is left unchanged after a night’s sleep, is unacceptable on its face. For its part, the defense may (but is not obliged to) present an alternative theory of the events associated with the crime.

What is interactional theory?

Interaction theory (IT) is an approach to questions about social cognition, or how one understands other people, that focuses on bodily behaviors and environmental contexts rather than on mental processes.

Can time be bent?

Science does support some amount of time-bending, though. An observer traveling near the speed of light will experience time, with all its aftereffects (boredom, aging, etc.) much more slowly than an observer at rest.

What are the different types of theories of gravity?

There have been many different attempts at constructing an ideal theory of gravity. These attempts can be split into four broad categories: Straightforward alternatives to general relativity (GR), such as the Cartan, Brans–Dicke and Rosen bimetric theories.

Can a gravity theory be based on baryon-only matter?

Dodelson and Liguori see this solution to large structure formation as an important step for a gravity theory based on baryon-only matter. Other problems that their theory (or any alternative theory) will have to confront include accounting for the mismatch in galaxy clusters between mass and light.

What are the different types of alternatives to general relativity?

These attempts can be split into four broad categories: Straightforward alternatives to general relativity (GR), such as the Cartan, Brans–Dicke and Rosen bimetric theories. Those that attempt to construct a quantized gravity theory such as loop quantum gravity.

What is the new theory of gravity under investigation?

The new theory (or groundwork for it) under investigation would be Jacob Bekenstein’s relativistic covariant theory of gravity (TeVeS), published in 2004.
