For centuries, great thinkers have pondered why, given the hundreds of billions of planets in the galaxy, we have seen no compelling signs of intelligent life beyond Earth.

Now, scientists are mulling an intriguing possibility: if aliens exist, their technology may be only marginally better than ours. And having explored their cosmic neighbourhood for a while, they simply got bored and stopped bothering, making it difficult to detect them.

The scenario, described in a new paper, embraces the principle of “radical mundanity”, which shuns the notion of extraterrestrials zipping around the universe after harnessing physics beyond our comprehension. Instead, it proposes a Milky Way that is home to a modest number of civilisations with technology not wildly more impressive than our own.
