"There have certainly been great TED Talks... but then there are also TED Talks that are blatant pseudoscientific garbage...

Andromeda Galaxy's Actual Size If It Were Brighter
I found this too fascinating not to share. If you've ever seen a night photo odds are in the mix is the galaxy Andromeda, but it's scale is deceiving due to its brightness.

Mind boggling and if you're curious where it was sourced from and whether the scale is really accurate (it is by the way) check out this Reddit discussion thread: http://redd.it/1u2jyo
