RIP ‘Big Bang’ singularity?

[“What’s changed in the last 50 years” series] As noted in my January 17, 2019, post “Cosmological fact and fiction,” the Big Bang theory poses questions on “whether terms like ‘origin’ or ‘creation’ even apply; and the limits of language to even discuss the topic.” [1] So, perhaps a rethink was overdue on the topic,… Continue reading RIP ‘Big Bang’ singularity?

The cosmos is like a fluid?

So, the short answer is yes. A useful model, at a certain scale. How can that be? The cosmos is full of stuff. Vast collections of stars, planets, rocks, dust, gas. Chunked over vast distances. Not what our everyday experience considers fluid stuff. Well, in physics and engineering, fluid dynamics embraces what typically are referred… Continue reading The cosmos is like a fluid?

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,, 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 Milky Way — a game-changing discovery

As I’ve noted elsewhere (Beyond the infinity of black holes), it wasn’t long ago — maybe a 100 years or so, that our view of the cosmos was much more circumscribed. Those who studied cosmology — physicists, astronomers, et al, viewed our cosmos in a much different way, at a much different scale — basically… Continue reading Beyond the Milky Way — a game-changing discovery
