I am on vacation, so I’m not here, in the traditional sense of “here.” This is a pre-recorded announcement. I may be able to see this post when it goes live, but I’m not certain of that.
In general terms two things cannot be in different places at the same time; however, in the world of quantum theory, things change a bit.
As explained here:
Some people In our everyday reality (called the classical world), our physical laws say it’s impossible to be in two places at once. But, according to quantum mechanics, microscopic systems can be in two or more places at the same time, a principle called superposition (also called quantum weirdness—no explanation needed). Atoms and electrons can be in two places at once. New discoveries are showing that molecules in plants and cells in birds also share this seemingly impossible characteristic. And, some theories now suggest that the neurons in our brain and, incredibly, DNA might also use this special ability.
One of my favorite film scenes, guaranteed to creep anyone out, from David Lynch’s Lost Highway: (yes, that is an almost unrecognizable Robert Blake):
Everyone have a wonderful weekend!
