You might see people sharing a number and asking you to Google it: 5676977. What is it? A phone number? A secret code? Here's what we know.

The combination 5676977 is, apparently, a patent number for a cure for AIDS from almost 20 years ago. Or, at least, that's what it appears at first. It turns out it's more of an idea that might work, but I'm sure doesn't.

It's a common 'The government is hiding information from us' or 'It's all about money' conversation. Is there really a patent for the cure for AIDS? Who knows for sure?

Don't believe in so much hype. Just because you put something up on YouTube doesn't mean you're now a chemist.

You can read more from IFLScience, but it won't get you much further.
