The Great Filter is one explanation for why we haven’t heard from extraterrestrials.I have been obsessed with space and astronomy since I was a child. I love writing and making videos about topics in astronomy. NASA estimates that there are more than 10 billion terrestrial planets spread throughout our Milky Way galaxy. There are at least 1500 planets within 50 light-years of Earth. And the Milky Way is just one of an estimated two trillion galaxies in the observable universe.
