Evening Reading: 3D 3D

by Greg Mueller, Jan 08, 2010 5:00pm PST

Here's a fresh chatty for you all to enjoy on this Friday night. We've had our ups and we've had our downs, but it's been a pretty good first week to start off the new year. It will no doubt be remembered as vividly and with the same fondness as all the other first-weeks-of-the-year past. That is, not much at all.

The weekend is almost upon us. May yours be as fun and exciting as an endless stream of sharp news, snappy headlines, and witty comments from Faylor, Alice, Garnett, Jeff, and the rest of the Shack.

In case you missed it, here's a taste of all the fun and excitement we had today:

Anybody into or studied astronomy?

If a planet's moon exploded (for whatever reason... asteroid impact, etc)... could the chunks remain in orbit around their planet, and what form would they take? A ring like Saturn? Also how large could these chunks be? I know some planetary rings are assumed to be exploded moons, but most of the ones I've heard about are dust. I want to know if the chunks could be larger. Big sky boulders basically.

      I actually meant tides as in tides, but now that you mention gravity I would have to say that the moon disappear like that would probably affect Earth's orbit right?
