Don't believe everything you read.
The manuscript was created in 2005 as a joke, and the creators would send it as a reply whenever they got spammed with press releases or conference invites. That's how it made its way to the e-mail inboxes of the International Journal of Advanced Computer Technology. But for once, the submitting author was horrified to see his research get accepted.
Traditionally, a scientific paper is examined by unrelated experts in the field — a process called peer review — to make sure it isn't total bunk. Only after completing this process is it presented to the greater public with the journal's stamp of approval. But while this joke paper supposedly went through peer review (and was given a rating of "excellent," no less), that claim seems a little suspect.
The researcher who submitted the paper wasn't expecting to reveal this journal's issues, but other scientists have purposefully sent in bad work to do just that. From Vox.com:
Last April, for instance, a reporter for the Ottawa Citizen named Tom Spears wrote an entirely incoherent paper on soils, cancer treatment, and Mars, and submitted it to 18 online, for-profit journals. Eight of them quickly accepted it, asking for $1,000 to $5,000 in exchange for publication.
