Why is gravitation still considered a Fundamental Force when General Relativity says that it is a geometric effect of inertia and space-time curvature?
...Gravitation is by far the weakest of the four interactions. Hence it is always ignored when doing particle physics...
Gravitation, also known as gravity, is a natural phenomenon by which all objects with mass are attracted to one another. This force of attraction is directly proportional to the mass of the objects and inversely proportional to the square of the distance between them.
According to the theory of general relativity, gravitation is caused by the curvature of space-time. The presence of mass or energy causes space-time to curve, and objects with mass follow this curved path. This is why objects with mass are attracted to one another.
Gravitation is a force of attraction between objects with mass, while electromagnetism is a force between charged particles. Gravitation is always attractive, while electromagnetism can be either attractive or repulsive.
In comparison to other fundamental forces, such as the strong and weak nuclear forces, gravitation is considered a weak force. This is because it has a relatively small strength and only becomes significant when dealing with large masses, such as planets and stars.
Gravitation plays a crucial role in many aspects of our daily lives, such as keeping planets in orbit around the sun, causing tides in the ocean, and allowing us to walk on the surface of the Earth. It also has practical applications in fields such as space travel, satellite communication, and navigation systems.
