Is the theory of gravity proven?

Most everyone in the scientific community believe gravitational waves exist, but no one has ever proved it. That’s because the signals from gravitational waves are usually incredibly weak.

What is gravity theory?

A theory of gravitation is a description of the long range forces that electrically neutral bodies exert on one another because of their matter content. Best known of these is Albert Einstein’s general theory of relativity, which reduces to Newton’s theory in a certain limit.

Which is true about gravity?

Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe.

What is the difference between a law about gravity and a theory about gravity?

This is a law because it describes the force but makes not attempt to explain how the force works. A theory is an explanation of a natural phenomenon. Einstein’s General Theory of Relativity explains how gravity works by describing gravity as the effect of curvature of four dimensional spacetime.

Does quantum mechanics explain gravity?

Quantum mechanics suggests everything is made of quanta, or packets of energy, that can behave like both a particle and a wave—for instance, quanta of light are called photons. Detecting gravitons, the hypothetical quanta of gravity, would prove gravity is quantum. The problem is that gravity is extraordinarily weak.

What is Verlinde’s theory based on?

Verlinde’s Theory is based on entropy through entanglement. When particles “unpack” in space they gain additional degrees of freedom but quantum entanglement is responsible for the forces that hold spacetime together, like cobwebs tying all quanta forming the fabric of the Universe. This acts as stretchy “gravity”.

Is the lensing effect of gravity a theory?

A team led by astronomer Margot Brouwer (Leiden Observatory, The Netherlands) has tested the new theory of theoretical physicist Erik Verlinde (University of Amsterdam) for the first time through the lensing effect of gravity.

How many galaxies have Verlinde’s predictions been measured?

Brouwer and her team measured the distribution of gravity around more than 33,000 galaxies to put Verlinde’s prediction to the test. She concludes that Verlinde’s theory agrees well with the measured gravity distribution.

Is gravity stronger than Einstein’s theory of gravity?

Astronomers have measured, however, that at distances up to a hundred times the radius of the galaxy, the force of gravity is much stronger than Einstein’s theory of gravity predicts. The existing theory only works when invisible particles, the so-called dark matter, are added.
