it by pushing or pulling. And whenever we push or pull an ob-
ject, we feel pushing or pulling forces on ourselves. Newton
called this action and reaction. Light also acts on matter, but light
particles have no inertial property. We can see light reacting with
objects, as when a laser beam cuts through metal or repairs a dam-
aged retina. But we can never perceive the actions and reactions
that matter has on light. Physicists refer to light’s inability to be
pushed or pulled as “its absence of any rest mass.” 33
Rest mass is the mass of a body when at rest, in other words,
it is a fixed entity. Yet when it comes to light, it is never at rest: It is
in a state of constant movement. Therefore, light is a form of ener-
gy that lacks mass and for that reason does not exhibit a basic char-
acteristic of “matter.”
Fred Alan Wolf describes this state of affairs:

When we see light, we really don’t see light at all: we see an effect
appearing as a result of light pushing and pulling on the matter
making up our sensory bodies. We see matter moving. Light itself is
really out of this world . . . 34
