Mysteries of physics summary

Here’s my summary of my feedback to the 18 biggest unsolved mysteries in physics by Natalie Wolchover and Jesse Emspak: Mysteries of physics part1 What is dark energy? Think of the universe expanding because space has an innate pressure, like a squeezed-down stress ball. Then think of a bubble-gum balloon in vacuum. As it expands the skin gets thinner and weaker, and less able to resist the further expansion. So it expands further, so the skin gets even thinner and weaker, and so on. So the…

Mysteries of physics part4

This is the fourth and final section of mysteries of physics. I’m working through the 18 biggest unsolved mysteries in physics by Natalie Wolchover and Jesse Emspak. In doing so I’m forming an opinion that some mysteries are nothing of the kind. I’m also forming an opinion that some physicists and institutions peddle mystery in order to promote themselves, because they aren’t doing useful science. More on that another day. Meanwhile, on with the show: When sound waves make light Though particle-physics questions account for many…

Mysteries of physics part3

Again carrying on from last week, I’m working through the 18 biggest unsolved mysteries in physics by Natalie Wolchover and Jesse Emspak. I’ve done the first nine. The next topic concerns grand unified theories, the sort of thing Alan Guth was thinking of when he came up with inflation. A grand unified theory or GUT is said to be a step toward a theory of everything or TOE. Do the universe's forces merge into one? The universe experiences four fundamental forces: electromagnetism, the strong nuclear force, the…

Mysteries of physics part2

Carrying on from last week, I’m working through the 18 biggest unsolved mysteries in physics by Natalie Wolchover and Jesse Emspak. Of course, not everybody would come up with the same list, so if there’s anything you’d like me to talk about, please drop me a line using the contact form. OK, where were we? We’ve had dark energy, dark matter, the arrow of time, parallel universes, and the mystery of the missing antimatter. Next is the fate of the universe: What is the fate of…

Mysteries of physics part1

When I google on mysteries of physics, a whole pile of websites comes up. Top of the list is the 18 biggest unsolved mysteries in physics. It’s a Livescience article written by Natalie Wolchover and Jesse Emspak. It makes for interesting reading, especially for me. That’s because I’m the physics detective. I solve mysteries. Some people don’t. Instead some people peddle mystery. Because mystery sells, just like quantum sells. That’s why CERN peddle the myth that antimatter might fall up, even though everybody who knows about…
