A guy named Michael Stevens has a YouTube channel called VSauce with almost eight million subscribers...and his videos have over 675 MILLION views total. He also makes over a million dollars a YEAR from YouTube revenue.

But unlike most YouTube celebrities, he does it by putting out EDUCATIONAL videos.

Most of his videos answer off-the-wall science questions. Like, what would happen if everyone on Earth JUMPED at the same time? The answer, by the way, is that even if all seven billion of us stood shoulder-to-shoulder in the same spot...it would only cause a somewhat MINOR earthquake.

His newest video is called "Spooky Coincidences", where he lists crazy facts...like that the speed of light in meters has the exact same string of numbers as the latitude for the Great Pyramid of Giza in Egypt.

Or that if you reverse the audio of Neil Armstrong saying, "That's one small step for man"...it sounds like he says, "Man will SPACEWALK."
