What are examples of unseen forces?

Answer 1

Gravity

As for the science behind the action, we know that Isaac newton defined gravity as a force -- one that attracts all objects to all other objects. We know that Albert Einstein said gravity is a result of the curvature of space-time. These two theories are the most common and widely held (if somewhat incomplete) explanations of gravity.

In this article, we'll look at Newton's theory of gravity, Einstein's theory of gravity and we'll touch on a more recent view of the phenomenon as well.

Although many people had already noted that gravity exists, Newton was the first to develop a cohesive explanation for gravity, so we'll start there.
