The New Gravitational Theory

The new gravitational theory, known as the theory of relativity, was proposed by Einstein. It became more comprehensive than the theory proposed by Newton.

The law of Universal Gravitation, proposed by Isaac Newton in the 17th century, was fundamental for the development not only of astronomy, but of physics in general. Currently, ideas about gravitation are greatly altered and expanded by the theory of gravitation proposed by Einstein in 1915, known as the General Theory of Relativity.

It is on the basis of this theory that, even today, scientists interpret phenomena that occur not only in the solar system, but throughout the Universe. Gravitational theory became much more comprehensive, involving fantastic distances and new astronomical objects such as black holes, neutron stars, galaxies, and quasars.

The enormous advances observed in the construction of telescopes, in modern electronics, in computers and in space flights transform research related to gravitation, until then confined almost exclusively to theoretical studies, into a huge experimental undertaking. In this field, one of the ideas that has been attracting great attention is the search for gravitational radiation, that is, for the existence of gravitational waves that would be emitted by matter in a similar way to the emission of electromagnetic waves by electrical charges.
Everything indicates that the concern to verify the existence of these gravitational radiations will be one of the main research objects in the field of New Physics in this century, opening, thus, a new and wide window for the knowledge of the Universe.
