Fermi Paradox

For centuries, humans have been fascinated with the idea of extraterrestrial life. The search for intelligent life beyond Earth has been a topic of interest for scientists, philosophers, and science fiction writers alike. However, despite decades of searching, we have not found any evidence of intelligent life beyond our planet…

Could an advanced extraterrestrial civilization blend in? — There’s a mystery at the heart of our modern civilization. Why does it seem humanity is like an uncontacted tribe even though numerous stars are in the sky and more exoplanets are discovered yearly? The answers we get from established institutions are usually not satisfactory. They claim there is no…

We know that there are about a trillion stars in the Milky Way. We know that at least one of them has an intelligent civilization. We know that the Sun has sufficient metallicity to have rocky planets, and that Earth has liquid water on its surface. These seem to be…

Why we cannot see any aliens out there — TL;DR: I will explain The Fermi Paradox in five levels to different audiences. Child Have you ever looked up at the stars at night and wondered if there might be aliens out there on other planets? Scientists have been wondering about this too for a long time. There are many stars…

In 2020, a team of 24 scientists published a paper in The Lancet in which they forecast that the global population will peak in about 40 years’ time and then start to irreversibly decline. To quote the authors: “[O]nce global population decline begins, it will probably continue inexorably.” This decline…

We have sent thousands of signals through the solar system and outside of it. We have detonated atomic bombs on our own planet, which means we have found the matches that resonate maybe even through the galaxy for all we know. But they are still silent.. So where are they? …

There’s a pretty simple formula for calculating when we destroy ourselves. First you identify technology that can potentially destroy you. Next you determine the cost of the technology, and calculate the number of people who can afford it. Next you calculate the intelligence required to make it all work, and…

The Fermi paradox can be expressed by the question: “If it is so likely to find planets in the universe with conditions suitable to support life, why have we not yet discovered evidence of advanced extraterrestrial life?”. The following is the Drake equation, referred to by articles on the Fermi…
