What is the elusive origin of gravity?

In summary, the origin of gravity remains elusive and is still a topic of much debate and speculation among physicists. While some theories, such as the Big Bang, attempt to explain the origin of gravity, there is no definitive answer. Gravity is often described as the way matter affects geometry, but this concept raises further questions and puzzles about the nature of gravity and its relationship to the other fundamental forces. Despite our current understanding of gravity through theories like General Relativity, there is still much to be explored and understood about this mysterious force.

Because it's right under our noses.

That is, the robust manifold (continuum) i.e. pseudo-Riemannian spacetime, is right under (and part of) our nose etc.

1. What is gravity?

Gravity is a natural phenomenon by which all objects with mass are brought toward one another. It is one of the four fundamental forces of nature and is responsible for the attraction between objects.

2. How does gravity work?

Gravity is the result of the curvature of space and time caused by the presence of mass or energy. The more massive an object is, the stronger its gravitational pull will be. This pull decreases as the distance between objects increases.

3. What is the elusive origin of gravity?

The origin of gravity is still a mystery and is a subject of ongoing research and debate among scientists. Some theories suggest that gravity is a fundamental force that has always existed, while others propose that it is a byproduct of other fundamental forces.

4. How was gravity discovered?

The concept of gravity has been known since ancient times, but it was not until the 17th century that Sir Isaac Newton developed the theory of gravity and its laws of motion. Later, Albert Einstein's theory of general relativity provided a more accurate understanding of gravity.

5. Can gravity be explained by quantum mechanics?

Currently, there is no widely accepted theory that explains gravity within the framework of quantum mechanics. Many scientists are working to reconcile the two theories, but it remains a challenge and an area of ongoing research.
