Newton vs Einstein: Gravity Concept

In this video Professor Brian Greene compares the views of gravity according the Newton and Einstein.

Newton: “gravity is the attractive force between all objects with mass.”

Einstein: “gravity is the bending of space and time by mass.”

In the 17th century Newton concluded that objects fall because they are pulled by Earth's gravity. Einstein's interpretation was that these objects do not fall. According to Einstein, these objects and Earth just freely move in a curved spacetime and this curvature is induced by mass and energy of these objects.

According to the theory of general relativity, gravity is the result of distortions in space-time created by mass and energy. The principle of equivalence states that that both mass and acceleration distort space-time and are indistinguishable in comparable circumstances.

Albert Einstein said about Newton that "His clear and wide ideas will forever retain their significance as the foundation on which our modern conceptions of physics have been built." Einstein's theories of relativity overturned Newton, but Einstein had the greatest respect for Newton's work on physics.

To summarize the two views of gravity, Newton envisioned gravity as a tug of war along the line connecting any two objects in the universe. In contrast, Einstein envisioned gravity as a bending of space-time by mass.

I really like the way how Dr. Greene talks.

I want to see a video of them trying to explain that kind of gravity but keeping the 3D lines. Not just a flat plain.

Knowledge, imagination and what makes us better?

The explanation of gravity as a curvature of spacetime is a simplified model that does not fully capture its complexity. In reality, the phenomenon is far more intricate than the analogy of a single plane with a depression. Gravity involves a complex interaction within a quantum field, where gravitational forces interact with one another in a highly interconnected and dynamic fabric. This framework extends beyond the classical understanding and incorporates quantum-level interactions that contribute to the overall behavior of gravitational phenomena.

Maybe it is Time to Rename Gravity: of weight is only a conclusion of two things working on Each other. Maybe we should call Gravity „to-be-there-force“ or in german: „Daseins-Kraft“

It bends space 3 dementially. Show it that way.
