The Field

A field is an area or region where something happens. In a field of flowers, flowers are growing, and in a field with grassing cows, there are cows. A football field is a place where people play football.

A field is not of much interest if there is nothing in it. Nothing much happens on a football field if there are no players. A field of flowers with no flowers isn't much to look at either, and there is no grassing in a meadow without cows.

What's in the field are physical objects. They in turn make things happen. There is no football game going on in a football field without players. There is no grassing in a meadow without cows, and there is no flowering in a field without flowers.

Similarly, there is no energy in an energy field without bits of stuff with energy. There is no force in a field without particles entering or leaving the field, producing over-pressure or under-pressure in the process.

For some reason, this obvious fact escapes the average physicist. In physics, there are force fields without anything going on. There can be energy in a field without anything to carry it. It is as if there is grassing going on in the meadow without any cows, and there is football being played without anyone ever touching the ball.

In the Velcro universe on the other hand, there is no energy or force without particles. Nor is there any distance or time. Without particles, there is nothing, not even a field.
