This image is related because portals are actual science. At least, I hope so. I've invested quite a bit of time under the assumption that they are!
Way, way back during Nightly Roundup #4, Seth posted an article by a pony from Ponychan wherein the ages for the mane six were figured out. Skaijo wasn't satisfied with the explanation or the results, so himself and another pony friend of his set out to set the record straight with the help of the original author. The result was a comprehensive scientific report, with documented references, of the best estimate we can give for the ages of these marshmallow ponies.
Or, as he said in the email, the result was, "a very clear, condensed discovery backed by some of the brightness upcoming minds in MLP fandom since Bill Clinton."
That may sound like fluff to most of you, mostly because that was a joke, but upon opening the document I was actually fairly impressed by how official it looked. This could pass as a scientific paper, it's that good.
There was an attached PDF, but I don't have a place to host it, so I'll include the linked Google Docs format instead, which you can peruse here.
If for some reason you don't like Docs, you can also view it on Scribd, here.
