Look up in the sky. It's a bird! It's a plane! It's a...a...what the heck is that?

This skydiver in Norway went for a dive back in 2012, but the video has only gone viral now because there's some debate about whether a meteorite flies by him.

You have to look closely around the :28 mark when some mysterious object briefly appears on the screen. The skydiver says he didn't even notice the object while he was falling -- it was only when watching the video that it caught his eye.

Researchers have tried unsuccessfully to find the rock on the ground.
