Einstein was not the first to discuss gravitational waves

After the press releases about finding gravitational waves, they all turned to Einstein. However, history shows that Henri Poincaré was the first to predict this type of wave.

In June 1905, French scientist Henri Poincaré predicted the existence of gravitational waves as a prerequisite for space-time relativity.

He raised this issue in Sur la dynamique de l'electron (June 5, 1905) published by the Academie des Sciences of France.

Henri Poincaré - who introduced the concept of gravitational waves.

In his report, Henri Poincaré not only shaped the problem but also developed Lorentz's idea of space-time transformation.

He said that the theory of relativity must be applied to all forces, not just for electromagnetic interaction.

Henri Poincaré pointed out that after the transformation of space-time, gravity will produce waves moving at the speed of light like electromagnetic fields.

However, for some reason, all the research on gravitational waves later on was reported by Albert Einstein.
Lorentz and Poincaré's research and contributions have been forgotten.

In the theory of special relativity, Lorentz and Poincaré argue that the speed of light is not only reserved for a certain object (light) but is the common parameter in the space-time system.

Thus, no object or signal can move faster than the speed of light.

Henri Poincaré also emphasized that the space-time system defined by the Lorentz transformation is applied to all forces including gravity.

Therefore, gravity cannot be transmitted immediately but must move at the speed of light.

Lorentz - a physicist specializing in electromagnetic fields.

Considering the case of interaction between two objects, Henri Poincaré introduces the concept of "gravitational waves" moving from the first object to the speed of light. After a period of time, gravitational waves will approach the second object.

More than ten years later, with the general theory of relativity, Albert Einstein studied the idea of ​​Henri Poincaré more carefully in the case of the static universe with space-time bent by gravity.

However, the fundamental principles of Henri Poincaré have not changed.

Not only that, another person was also mentioned by Henri Poincaré, Laplace, a French scientist under Napoleon.

Pierre-Simon de Laplace also considered the possibility of gravity traveling at a certain speed limit, but Laplace did not pay attention to the problem of space-time.

Laplace - the famous mathematician with the L. transformation.

In addition, the idea of ​​gravitational waves was also mentioned by Oliver Heaviside in his studies. He is a British scientist specializing in mathematical, physical, and electromagnetic research.

Although not known as other scientists, many of Heaviside's works changed the technology of communication, mathematics and many other sciences later.

Oliver Heaviside - silent scientist.

Thus, Henri Poincaré developed his idea according to Laplace and Lorentz. All are clearly noted in their articles.

It is these studies that are the foundation for Albert Einstein to make his announcement. Unfortunately, the contributions of Henri Poincaré, Lalace, Lorentz and Heaviside have been overshadowed by the image many people know about Albert Einstein.
