The Nature of ForceThe Nature of Force

What we know.......What we know.......1)1) A force is a push or pull.A force is a push or pull.2)2) Forces must be applied to an Forces must be applied to an

object.object.

And Fields?And Fields?1)1) Are invisible lines of force between Are invisible lines of force between

objects.objects.So, if forces require physical contact So, if forces require physical contact

how can fields transfer force?how can fields transfer force?

Electrons act as discrete objects as Electrons act as discrete objects as demonstrated by the photoelectric effect, demonstrated by the photoelectric effect, which is how your digital camera works.which is how your digital camera works.

Electrons also act as waves which is why Electrons also act as waves which is why they are confined to distinct shells as they are confined to distinct shells as DeBrogelie found.DeBrogelie found.

Should you attempt to directly observe the Should you attempt to directly observe the which form the electron is it will change which form the electron is it will change to the other form since it takes energy to to the other form since it takes energy to make the observation. HUH???????????make the observation. HUH???????????

In order to obey the rules we create a “particle” that obeys the rules. Essentially we rig the game.

This process is called a “virtual construct.”

The density of the virtual photons is greater closest to the charge.The density follows the beloved inverse square law.But I think we have a problem with COE.

Page 19: Quantum Electrodynamics

This is simply not possible!!!!!!!!!!!!

Page 20: Quantum Electrodynamics

We can not violate COE, it is the fundamental rule of the Universe.Maybe we can be uncertain of the system total for a short time.

Think about a bank account.Think about a bank account.You have $500 in an accountYou have $500 in an accountThen write a check for $700Then write a check for $700So long as have $700 in the account So long as have $700 in the account

before the check clears you’re OK before the check clears you’re OK with the bank.with the bank.

The system tolerates short duration The system tolerates short duration imbalances so long as the account imbalances so long as the account reconciles by the end of the event.reconciles by the end of the event.

More importantly, to make a direct observation of the event changes the event!!

The impact dislodges the electron orphaning the virtual particles. Once they are orphaned for a Planck Time unit they flash into reality in the form of light.
