Ergosphere – what?

Regarding recent posts about black holes, here’s another YouTube video by The Science Asylum on the topic (published February 16, 2019): “Black Holes can SPIN?!?” I’ve previously highlighted The Science Asylum as a science communicator. This latest video is an interesting overview of black holes: non-spinning vs. spinning, the math vs. reality inside and outside… Continue reading Ergosphere – what?

The future of (particle) physics?

I’ve encountered some articles recently about the current state of particle physics. Or, more broadly, “the direction of theoretical physics .” Concerns about its future. Whether new particle accelerators are needed (or even viable). An expensive rabbit hole. That research has become mired in wishful elegant mathematics. The absence of evidence being evidence of absence. I… Continue reading The future of (particle) physics?

The Milky Way’s shape — a peculiar disk

Popular media is abuzz today with news regarding research by NAOC (National Astronomical Observatories of Chinese Academy of Sciences) on the shape of our galaxy, the Milky Way, published in Nature Astronomy today. A peculiar disk. A new 3D model. Original article on Nature Astronomy: “An intuitive 3D map of the Galactic warp’s precession traced by classical… Continue reading The Milky Way’s shape — a peculiar disk

Cosmological fact and fiction

In the last few months, I’ve been struck by how many articles have been published in the popular media and science news about black holes and the Big Bang. Mainstream physics and science communications (like phys.org, quantamagazine.org, etc) lately seem to be discussing more and more “mind blowing” geometries of the universe (or multiverse, eh).… Continue reading Cosmological fact and fiction

Holiday meditation – part of a cosmic perspective

This Scientific American post “A Thanksgiving Meditation in the Face of a Changing Climate” (November 21, 2018) is an interesting take on gratitude — from a cosmic perspective. And ESA’s video “Space Station 20th: longest continuous timelapse from space” is the type of thing which makes for interesting meditation as well. Here’s an excerpt from “A… Continue reading Holiday meditation – part of a cosmic perspective

Communicating what physics says — Domain of Science YouTube channel

Today’s post is somewhat different than usual. I’m highlighting a YouTube channel. Communicating science to a general audience has a long history. The bibliography for my physics blog contains some books by authors to this purpose. Modern physics has many great stories, and the just plain strangeness of quantum physics lends itself to great storytelling.… Continue reading Communicating what physics says — Domain of Science YouTube channel

Acceleration causes gravity, gravity causes acceleration

As I’ve written elsewhere,  I sometimes think that generations of scientists raised in space might help advance physics, having lived in a world dominated by inertia (rather than friction). Especially in regard to a visceral understanding of microgravity. Like characters in the TV series The Expanse. So, this Space.com article (June 18, 2018) “Relativity: The… Continue reading Acceleration causes gravity, gravity causes acceleration
