I’ve been so busy over the last week or two, what with my birthday, Justine’s birthday, and the site dying that I forgot to discuss my light cone and it’s enveloping Zeta Tucanae.

A (future) light cone is the boundary of the causal future of a point and the past light cone is the boundary of its causal past. Basically, it’s space that I could have influenced just by existing. Of course, it’s a load of hogwash but it’s interesting to thing how far theoretical light created at the time of my birth could have travelled.

In another three months, my light cone will envelop Chi-1 Orionis which just happens to be in the Orion constellation and includes Orion’s Belt, which I’m sure everyone has heard of, even if they’re not interested in astronomy (like I’m not).

If you’d like to see what your own light cone has enveloped, you will need something capable of reading RSS (or knowing how to decipher XML) and then you’ll have to bookmark the RSS feed.
