Space Industry Expert Shares Why She Doesn't Think Aliens Have Been To Earth

The distances are unimaginably large.

The Fermi paradox is a philosophical argument that, briefly, observes that the chance for extraterrestrial life is slight, due to the fact that if there are other things out there, then they probably should have visited here already. Our solar system is relatively young compared to the age of the rest of the universe, giving other civilizations plenty of time to arise, develop faster-than-light travel, and come visit. So where are they?

For this space program communications expert, she thinks they just don’t have any idea we’re here.

In this video, “Astro Alexandra”—who helps interpret aspects of space, space exploration, and other scientific facts for laymen on social media—explains that when it comes to space, we’re dealing with impossibly big numbers. Distances so large our human brains can hardly comprehend it.

Think about it this way: our first radio signals were sent out barely a hundred years ago. Even when we started directing signals into deep space—in 1974— the star cluster our rudimentary message was sent to was 22,000 light-years away. It hasn’t gone very far, yet.

But, this argument assumes that the only way aliens would come here would be if they heard about us. Are we really all that impressive?

Maybe aliens happened upon us, the way we might happen upon a pretty flower while out on a hike. They don’t have to know we’re here in order to come check us out.

Then again, space is unimaginably large. So it would have to be a pretty big hike.
