Neil de Grasse Tyson Explains Nothing

[gln1955]

Neil deGrasse Tyson is a genius. He's made a career out of being an expert on nothing.

We have a problem with nothing.

Vacuum energy is an underlying background energy that exists in space throughout the entire Universe. The vacuum energy is a special case of zero-point energy that relates to the quantum vacuum.

Unsolved problem in physics: Why does the zero-point energy of the vacuum not cause a large cosmological constant? What cancels it out?

The effects of vacuum energy can be experimentally observed in various phenomena such as spontaneous emission, the Casimir effect and the Lamb shift, and are thought to influence the behavior of the Universe on cosmological scales. Using the upper limit of the cosmological constant, the vacuum energy of free space has been estimated to be 10−9 joules (10−2 ergs), or ~5 GeV per cubic meter. However, in quantum electrodynamics, consistency with the principle of Lorentz covariance and with the magnitude of the Planck constant suggests a much larger value of 10113 joules per cubic meter. This huge discrepancy is known as the cosmological constant problem.

Some folks say that a lot of men have a "nothing box." It is a place we go to relax and think about nothing. Some folks also say that many women don't have a "nothing box." This could explain some things. When your significant other approaches you and asks that dreaded question. "What are you thinking about?" I say "nothing" to mrs. slo but she seldom buys it. "Oh come on you must be thinking about something." "Nope, I'm not and I don't want to talk about it."
It may also explain why some men like to channel surf and some women get annoyed by that.
Please don't hate me. I'll have to retreat to my nothing box.

Like Bill Monroe said, “That ain’t no part a nothin’.
