Now's Your Chance To Talk to James Cameron and Jane Goodall About ScienceS

Everyone could do with a little extra science today, if only to distract themselves from the blank and empty yawn that is a Sunday afternoon. To celebrate their 125th anniversary, National Geographic is hosting a free-for-all interview with James Cameron, Robert Ballard, Jane Goodall and "explorers in the field on every continent." You can join the conversation here; explorers will be taking questions for the next hour.

It's a new age of exploration-and you're invited.

Join some of National Geographic's biggest names in exploration and innovation for a Hangout on Air right here on Google+.

Post questions for our explorers here or via a YouTube video using #NatGeo125 for a chance to see them asked on air.

Don't forget to tune in at +National Geographic or at youtube.com/natgeo on Sunday, January 13 at 1 p.m. ET (6 p.m. UTC).

Questions so far include "My 9 year old [there is almost certainly no nine-year-old] wants to know how does poop fossilize?," "I worry about the polar bears :(," and "This is epic." All of which are legitimate points, but we can do better. If you'd rather hassle James Cameron about Avatar than find out what it feels like to descend into the Mariana Trench or get wetgear recommendations from a Russian caver or tell Jane Goodall that she is a tower of beauty and resilience, then I will simply leave you to yourself.

Presumably poop fossilizes like everything else, right? I don't want to disregard that question out of hand, but I can't think of anything about it that would disrupt the normal fossilization process.
