Photographing a black hole?

As teased earlier this month, today the Event Horizon Telescope (EHT) project announced and presented the first ever photographs of a black hole — “the last photon orbit.” Another epic story of big science and an international team. The interplay of models and simulations, data capture, and complex processing. And funding. Much news coverage. Here’s… Continue reading Photographing a black hole?

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?

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

Celebrity and cultural phenomenon — Stephen Hawking

Stephen Hawking died last week. Lots of tributes in the media about his scientific legacy and life. Sean Carroll posted an article on his blog on March 16: “Stephen Hawking’s Scientific Legacy.” It’s particularly interesting. As a career physicist and cosmologist, Carroll met and interacted with Hawking over the decades. Early in his career Carroll turned… Continue reading Celebrity and cultural phenomenon — Stephen Hawking

Beyond the infinity of black holes

As noted previously, quantum physics has struggled with infinities. A recent Space.com article on black holes reminded me of another part of that saga. Black holes serve as touchstones in several ways. Wiki: … there are some theoretical circumstances where the end result is infinity. One example is the singularity in the description of black… Continue reading Beyond the infinity of black holes
