Kylie Jenner spent her Memorial Day sitting on countertops wearing one shoe and sharing conspiracy theories on social media.

The celebriteen tweeted an image posing questions common amongst chemtrails conspiracy theorists, who believe that condensation trails planes leave in the sky — contrails — are actually infused with chemical or biological agents for sinister purposes.

It's unlikely the picture was posted by a hacker, considering the tweet has not been deleted and Jenner has tweeted since it posted on Monday.

The image itself, which takes plenty of liberties with the English language, is old and dates back to at least 2013. But you could probably assume that Jenner didn't make the graphic, based on the fact that the 17-year-old probably does not drive to work every day.

Jenner proved to be shaky at best when it comes to trustworthiness, after vascillating about getting lip injections. However, she remains influential — the chemtrails image had been retweeted more than 4,000 times at the the time of writing — so it's important to take a quick look at the science behind the theory.

Proponents of the chemtrails conspiracy theory are suspicious of the fact that certain contrails seem to take a much longer time dissipating. They say these are actually a form of warfare, blaming them for a host of ills on the planet's surface. However, in reality (PDF), factors like humidity and air density affect how the exhaust the plane emits will condense and how long it will linger. The most that they do is alter the amount of solar energy reaching the surface and escaping from the atmosphere, but that's a small amount compared to greenhouse gases and other manmade factors.

It's unclear how deep into chemtrails conspiracy theories Jenner is. Maybe she's just trying to ask thought-provoking questions to fill the void left by Twitter's preeminent teen philosopher Jaden Smith, who sadly abandoned his @OFFICIALJADEN handle earlier this month.

If Jenner wants to get into conspiracy theories, she should take advantage of her coveted supply of famous family friends.
