Kit Bashir<p>Betelgeuse, the Red supergiant star in Orion that is not pronounced ANYTHING like that movie godsdammit, does have one thing in common with it. Teetering on the brink of Supernova, variously predicted to blow up tomorrow, in the next 100 kiloyears, or already (modulo light speed lag), it waited to be called.</p><p>Our uncertainty about its state of assplodery stems from our uncertainty about its mass, which in turn arises from our uncertainty about its distance. The reason we’re not completely sure whether it’s 400 or 1200 light years away (far enough to be non-earth-shattering when it does kaboom, in any case) is that its death-throe fuzziness (this beast of a star would extend to the orbit of Jupiter if you swapped it for our sun) makes measurement of stellar parallax really frickin’ hard. </p><p>The Henrietta Swan Leavitt Tachyon Ranging Observatory was built to solve problems like this. It works like RADAR only it uses tachyons, those mirror particles of normal matter which can only travel /faster/ than light, never slower. This morning the HSL fired three tachyon bursts at Betelgeuse, awaiting echoes which ought to return in just minutes, not centuries. Two came back. The distance to Betelgeuse is 714.5 light years. That means light from its supernova explosion will arrive in 714 years, six months and five minutes. Whoops, our bad.</p><p><a href="https://aus.social/tags/Tootfic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Tootfic</span></a> <a href="https://aus.social/tags/MicroFiction" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MicroFiction</span></a> <a href="https://aus.social/tags/PowerOnStoryToot" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PowerOnStoryToot</span></a></p>
