SUMMARY

The Casimir effect is observable at a specific distance, denoted as d, between two plates. This effect is characterized by a strong dependence on distance, following the mathematical relationships of 1/r6 or 1/r8. The discussion raises the question of whether there is a threshold distance below which the effect is not observable, or if it tapers off gradually with increasing distance. Understanding these dependencies is crucial for further exploration of the Casimir effect.

In the Casimir effect, there is a distance d between the plates where the effect is observable. Is this a threshold effect, so that for any non-zero distance \delta, the effect is not observable at d+\delta, or does this effect taper off? What does this depend on?

It is a strong function of distance: 1/r6 or 1/r8.

Interesting. Thank you. I should get more into the math involved.
