As I freelance for other websites, I thought I’d begin posting links and summaries here on a quasi-regular basis so you can keep up with the other space stuff I write about. So, to kick off the Astroengine Roundup, here you go:
Using TARDIS to Mathematically Travel Through Time (HowStuffWorks.com)
Ever since H. G. Wells wrote “The Time Machine” in 1895, we’ve been fascinated with the possibility of magically bouncing around through history. But it wasn’t until Einstein published his historic theory of general relativity that scientists (and science fiction writers) realized that time wasn’t necessarily as ridged as classical theories predicted. After a thought-provoking chat with general relativity expert Ben Tippett, of the University of British Columbia, I was able to get the lowdown on his mathematical model of a time machine called… TARDIS.
Comets Are Oxygen Factories (HowStuffWorks.com)
When Europe’s Rosetta mission discovered molecular oxygen venting from comet 67P/Churyumov-Gerasimenko in 2015, scientists were weirded out. In space, molecular oxygen (O2, i.e. the stuff we breathe) is highly reactive and will break down very quickly. The working theory was that the O2 had been locked in the comet’s ices for billions of years since the solar system’s ...
