At its core, the Fermi Paradox grapples with a puzzling contradiction: Considering the enormous size of the universe and the frequent discovery of potentially habitable planets, why haven't we heard from any extraterrestrial civilizations yet?
Despite our advancing technologies for astronomical observation and the ongoing search for extraterrestrial intelligence, we have yet to find concrete evidence of life beyond Earth.
![An artist’s concept looks down into the core of the galaxy M87, which is just left of centre and appears as a large blue dot. A bright blue-white, narrow and linear jet of plasma transects the illustration from centre left to upper right. It begins at the source of the jet, the galaxy’s black hole, which is surrounded by a blue spiral of material. At lower right is a red giant star that is far from the black hole and close to the viewer. A bridge of glowing gas links the star to a smaller white dwarf star companion immediately to its left. Engorged with infalling hydrogen from the red giant star, the smaller star exploded in a blue-white flash, which looks like numerous diffraction spikes emitted in all directions. Thousands of stars are in the background.]](https://assets.iflscience.com/assets/articleNo/76155/aImg/79193/jet-m.jpg)
