So the effective range of a force is where it is where it is no longer
detectable?
I knew it wasn't infinity.
But will science accept this?

We are certainly experiencing a component of acceleration toward it.
Of course a ball tossed in the air is accelerating downwards both on
the way up and on the way down.
No. Going up the ball decelerates.

Do you know how to use a dictionary or a science book? |

If slowing down is an acceleration then the Gamma will always be going
up. Clearly this is wrong.

You only know how to compound you errors.
Too bad.
Here's an 8th grade summer school lesson for you
on this subject:
"The teacher explains the concept of acceleration as being a change in
speed or direction. (It may be too much to explain how acceleration is
also a vector quantity.) This might be facilitated by drawing
trajectories on the board (with velocity vectors) and asking student to
identify places where acceleration occurs. This will take a while. Then,
arguing by its analogy with R*T = D, the teacher introduces the relation
A*T = V and discusses with the class how they might go about designing
an experiment to find A."

If 8th graders are expected to understand this then how come
a self proclaimed genius like you doesn't get it? |

Not quite.
A force becomes *negligible* when *its effects* are no longer
detectable.
Just because a force is weakened (i.e. by distance) to the point its
effects cannot be detected, that does not mean that it is
ineffective.
It just means that *our ability to measure the effects* has room for
improvement.

I believe that if a force's effect has no consequences any longer that
it could be considered as if it weren't there Tad. |

Can't be larger than that.
sorry, you are wrong as usual but will never admit it.

Nothing is infinite.
