What is The True Nature of Reality?
Get your geek on!
Is String Theory the final solution for all of physic’s questions or an overhyped dead end?
New Scientist usually puts out great stuff, but this video? Eh. I was tossed up over whether to post it or not. Check it out for yourself, maybe i’m missing something. 🙂

Every now and then an idea comes along that upends how we see ourselves and our place in the cosmos. The rumblings of the next revolutions in our thinking may already have started. Here are four potential “what ifs” with the potential to change us forever.
The galvanic skin response
I was recently asked to look into a product called Zyto technology. This is an electronic device that you place your palm on top of so that it can read your “galvanic skin response” (GSR) to specific stimuli. It then uses your responses to prescribe a specific treatment.
Quantum mechanics is a beautiful and still-controversial idea. It is rightly popular. What’s not right is the way people use it to justify any reality-bending idea in their novels, their TV shows, or their personal philosophies. “Quantum” does not mean anything you want.
“Captain? I’m afraid we’re getting quantum disruptions in the quantum energy field. Should I ready the quantum torpedoes and relay a quantum message to the quantum base?”
I’m not a savvy dissector of movies. All the physics mistakes in Gravity flew right past me, but when you see something done a certain amount of times, it works even the most unresponsive of nerves. The word “quantum” is regularly dropped into science fiction in a way that basically amounts to the storyteller thinking, “I bet this is the way smart people in the future talk.” It might be the way smart people talk, but as we see in the next section, it’s also the way people talk when they’re being really stupid. What’s more, it won’t be the way the educated people of the future talk about anything.
Science can move forward in sweeping generalities, or it can move forward by becoming more and more specific. Either way, you probably shouldn’t use “quantum” to describe future science. If you’ve got a universe where starships can move at above light speed, or people can teleport, or the brain can be uploaded into a computer, the term “quantum” may be as antiquated as the term “natural philosophy.”
If the term “quantum” is still around, it won’t be applicable in any specific situation. Let’s put it this way, there are five different major types of light scattering – Rayleigh Scattering, Mie Scattering, Tyndall Scattering, Brillouin Scattering, and Raman Scattering. If you’re an expert and working with scattered light in any meaningful way, saying, “light is being scattered,” isn’t specific enough to get anything done. You have to know what kind of scattering you’re dealing with. Having characters in a space craft worry about a “quantum energy field” near them makes about as much sense as having characters in a war say that the enemy is shooting “matter” at them. They’ll need to use specifics to make any progress.
A fun note: the types of light scattering are all named after scientists. Instead of saying “a quantum energy field,” have your characters run into “a Bass-Van-der-Woodsen field,” because in your universe the team of Bass and Van der Woodsen made the discovery, and an educated expert would name the field instead of just saying “it’s quantum.”
It Doesn’t Mean That We Are Psychic
Okay, here’s the big one. Quantum mechanics shows that the world works in unintuitive ways, and, yes, experiments done in quantum mechanics provide results that can be interpreted in ways that lead us to odd conclusions. What quantum mechanics doesn’t do is provide evidence for whatever whack-a-doodle theory any crackpot has at the moment. These theories come in several different flavors.
First there’s quantum entanglement. I have to admit, I have a soft spot for quantum entanglement. Entanglement involves two particles having opposite spins. As long as the spins aren’t measured, they’re undetermined. This doesn’t mean that we don’t know the spins. This means that they are literally . . .
