Experimental cosmology - selden - 03-13-2021
Realizing that the discipline of “Experimental Cosmology” already exists caused me a frisson of cognitive dissonance. I’m sure it means something quite different in Y11K.

Heh. That's almost as much fun as 'Applied Theology'.

Well, IIRC some of the highest energy events detected don't have a clear origins if you take for granted the current laws of physics. Again, IIRC, some of the most energetic gamma burst are explained by having a neutron start collapsing into a quark/gluon star.

Did someone said "archai" in here?

I guess some things could be fun to theorize on, like changing universal constants like gravity or the speed of light.
I remember fondly Baxter's "Raft" book on a universe with hypergravity.

Have you read Greg Egan's books? I haven't. I have too much else I haven't gotten to. But his website has the no-holds-barred extreme math behind his alternate laws of physics for his novels.

One of my favorites is "Eschatogeny" - studying the origins of world-ending events.
In the context of OA, where by this time thousands of worlds have actually ended, this is a very compelling field of study.
"Applied Eschatogeny" on the other hand is the domain of bomb-throwing anarchists, suicidal Archai-baiters, and embittered war criminals in adjacent star systems possessed of a starship drive and a very large hunk of rock.

First time hearing the name! Noted, thank you, seems quite good, at least from the titles.

I found some of his books to be slow going due to all of the exposition.
