Yippee ki-yay

A roundup from the fringes of physics ...

Do magnetic monopoles exist? (Think of a magnetic monopole as a tiny north pole without a matching south pole, or vice versa -- even though bisecting a bar magnet always produces two smaller bar magnets, each with a north and a south pole.) No magnetic monopole has ever been detected, but some post-Standard Model (hence, speculative) theories of particle physics allow for magnetic monopoles. Here's one more notion about how -- if magnetic monopoles are real -- we might detect them: "Can corkscrewing lasers solve an enduring particle physics mystery?"

Part of ITER, under construction
Will we ever have fusion reactors? It seems like controlled fusion technology has been twenty years into our future for at least fifty years. The latest forecast for international science's premier fusion project (the International Thermonuclear Experimental Reactor, aka ITER) is again forecasting success in about twenty years (2035, to be precise). See "ITER Council endorses updated project schedule."

About the status quo ...

No, this isn't a political rumination. I don't do those (and you're welcome).

The world as we know it ...
The standard model of particle physics has endured every challenge for more than half a century (see, for example, "LHC's Newest Data: A Victory For The Standard Model, Defeat For New Physics"). General relativity has withstood every challenge for a full century. And yet clearly our understanding of the universe is incomplete ...

Consider "Five Independent Signs Of New Physics In The Universe." If physics interests you, all five issues are worth a look -- but the item of most interest to me is dark matter. Bottom line: the behavior of such large objects as galaxies and galactic clusters doesn't fit with our understanding of gravity absent lots of unseen matter. If we do understand gravity -- the heart of general relativity -- then there must be lots of dark matter out there. But the standard model has no place for a dark-matter particle(s), and no search for dark-matter particles -- or for any particle physics beyond the standard model(*) -- has yet borne fruit.

(*) For example, super-symmetry or string theory.

Short stuff

If you haven't run across 'em, two of my short stories saw print (and electrons) this month.

In Analog, the January/February issue has "Paradise Regained." (And if you've lost track, I have another short story and a novelette in their queue.)

In Galaxy's Edge, the January issue also offers a short story of mine. The zine posts some of each issue, a subset which in this instance includes my contribution. Check it out: "The Torchman's Tale." (I have another short story in the queue there, as well.)

In related news, I completed the secret-history novella discussed in my last short-fiction roundup (aka, Short fiction. Shorter updates.). Then I knocked out a short story that came out of nowhere, demanding to be written. More news about both (and others?) as it happens.

With the holidays and the novella behind me, I really do need to get back to the latest, half-written novel ...

The news is astronomical!

Happy 2017, everyone! To kick off the new year, I thought I'd share some fascinating (to me, anyway) year-end 2016 astronomy news.

Dry as a bone?
Mars is super-dry, right? Well, yes and no. The surface certainly appears to be, but, as Phys.org reports,"Mars ice deposit holds as much water as Lake Superior." That should make eventual colonization easier. (Hey, the year is young. Permit me a bit of optimism.)

What lurks behind?
You'd think entire galactic clusters would be difficult to overlook. In general you'd be right. Even so, Cosmos reports that "Galactic supercluster found hiding behind Milky Way." (One of the many pluses of the new astronomical sub-specialty of gravitational observation is: gravitational waves pass through pesky obstacles like dust clouds and galaxies -- though that's not how this lurker was finally detected.)
