The force is with us, always? Tuning quantum vacuum forces from attractive to repulsive | ASU News
The Force is strong not only in "Star Wars" lore but also as a fundamental property in physics. For example, scientists can put two uncharged metal plates close together in a vacuum, and “voila!” — they will attract each other like Luke Skywalker and his trusted lightsaber.In 1948, Dutch theoretical physicist Hendrik Casimir first predicted an attractive force responsible for this effect — later dubbed the Casimir effect. A half-century later, in 1996, the Casimir force was experimental…
