First off...
Nibiru does not exist.The guy that made this emailed me a month or so ago and said that he never imagined that his joke would become so popular.
I never expected this hoax I made to get so popular. I figure you\'ll get a kick out of it:
I asked if he'd add a link to Universe Sandbox in the description...
Because you asked nicely I added it to both.
...me and a friend bought it the day it came out and we thought
"hey, this software is new, we can really freak out some crazy people
and then (hopefully) bring them back into sanity!" The intention
wasn't really to scare gullible people who didn't already believe the
world was going to end. It did get a little out of hand, hah.
To maintain the mood I put this on the main video:
"NASA Engineers use Universe Sandbox | http://universesandbox.com/"
To be clear, although people at NASA do know about and have used Universe Sandbox (out of personal curiosity), they're not using it in any formal way for science or research.
His only other video reveals that his original video is a hoax:
2012 NASA HoaxAnd in case anyone's still worried, don't be, there is no Planet X. Anything of the size claimed by the hoax would be detectable by amateur astronomers. If true, there would be no way this knowledge could be covered up. And to be extra clear,
Nibiru does not exist.
