U.S. House candidate Brianna Wu, a Massachusetts Democrat, is worried that people will drop rocks from the moon that will hit the earth and kill people.

Wu, who gained notoriety after getting involved in the GamerGate controversy of 2014 and is now challenging sitting Rep. Stephen Lynch, tweeted that she isn’t happy about SpaceX’s plan to ferry private citizens to the moon by 2018, for reasons that will make your head explode.

She also made it abundantly clear that she has no idea how gravity works.

Wu has since doubled down on her earlier assertions that the moon is dangerous because you can fire a large rock from it and hit the earth.

2/ Like, you all can make fun of that statement, but it will still be true. This is why the militarization of space is so dangerous. — Brianna Wu (@Spacekatgal) February 28, 2017

For the sake of fairness, let’s play along with Wu’s theory for a hot second. Let’s say that the moon, which is an estimated 238,900 miles away from earth, could potentially become a tactical base from which asteroids or missiles could be launched towards our planet.

Oooh, scary.

But if someone did intend to destroy our home planet from space, they wouldn’t need to send people to the moon to mine large rocks and build a really big slingshot aimed towards earth. It would be significantly cheaper and easier for someone to launch an orbital weapon into space that could rain missiles down on our planet at a closer range. Lucky for us earthlings, this kind of space weaponry has been banned for decades, thanks to a series of treaties dating back to the Cold War. Long story short, Wu’s concerns are very far-fetched and practically improbable, if not entirely impossible.

Wu isn’t the only Democrat who’s made an eyebrow-raising statement about physical reality. Rep. Hank Johnson (D-Ga.) once said he was afraid the island of Guam would tip over and fall into the ocean if too many people were on it at once.

“My fear is that the whole island will become so overly populated that it will tip over and capsize,” Johnson said.

That clip will never get old.

Hey Democrats, ya’ll should probably rethink the whole “we love science more than you” schtick until you can figure out what gravity is and how islands are formed.
