Alex complains that this space has become "dark and weird", a charge I wish to respond to by pointing out that, one day, our aging sun will become 256 times bigger and 2,730 times brighter. This, of course is bad news for our humble blue-green planet. In this edition of Ask a Science Student, we will discuss an upcoming article in the Monthly Notices of the Royal Astronomical Society, according to which Earth will be consumed by this out-of-control sun, but not for another 7 billion years or so. Fortunately, most of us will be dead by then, except for those who restrict their caloric intake and eat (or restrict, depending on what's fashionable) their anti-oxidants. I now turn over the keyboard to Riyaad to comment on this topic and to answer your questions.
