Could We Even Communicate With Aliens If We Found Them?

Posted on April 30, 2023 by willems49

This seems unlikely to me, given the extreme diversity […] Continue reading →

Where is Everybody?

At this very moment, the Voyager 1 spacecraft is hurtling through space at about 61,500 km/h each and every hour, carrying it ever further from our Solar system which it left 18 years ago. But despite this staggering speed, it would still take Voyager more than 75,000 years to reach the nearest star, Alpha Centauri. […] Continue reading →

The Search for Extraterrestrial Intelligence (SETI) has been ongoing for about 60 years now, and it’s time to reconsider if it’s worth the millions of dollars and hours it burns every year. To start off, I want to make the case that SETI isn’t real science. It’s a faith-based effort that isn’t falsifiable.
