In short, no. There is no way to artificially produce the massive densities. The densest everyday material is many millions of times less dense than what is needed to produce a tiny black hole.

Most craters from the early Earth have vanished. At North Pole Dome, one survived. Its rocks preserve the trace of a space impact from 3.024 billion years ago – a rare page from the violent youth of our planet, with the date still written in the stone.

Gravitational waves offer an entirely independent way to measure the expansion of the universe. These large ripples in the fabric of space-time are produced when extremely dense objects, such as black holes, collide.

Earth’s food would not necessarily be edible for them. Terrestrial protein might be of no use if their digestive systems used different amino acids. Our sugars might prove useless if their metabolism could not handle them. Our bacteria may devastate alien life – or perhaps not infect it at all.

Debates over the existence of extraterrestrials date back to the earliest Indigenous and western thought. The tools generating the evidence within western science, however, have changed — from the philosophical and theological arguments of the Ancient Greeks to the development of increasingly sophisticated telescopes and space travel and exploration.

Is our universe perfectly flat or does it have curvature to it like a sphere, or flare outwards like a horse saddle? That depends on how dense the universe is, and mapping galaxy clusters helps us measure the density of a hypothetical force known as dark energy.
