Re: [Phys-l] definition of gravity

Quoting John Denker <jsd@av8n.com>:

So what is the current thinking about gravitons and how they fit into
the equivalence principle?

The short answer is that gravitons do exist, in the sense that
there is theoretical evidence that they must exist, observational
evidence that they do exist, and no good reason to doubt that
they exist.

The shorter answer is equivalence is NOT equal.
Gravitons may "exist", but we may doubt that gravitons are the most fundamental physical entities.
