• After the deaths of his wife and daughter, Dr Olbers had recently given up his work as an opthalmologist to devote himself to his nocturnal passions: the stars, the Moon, meteorites and comets.
• He gained a solid reputation in the academic world and spent long nights observing the sky from the observatory on the second floor of his house.
• On that morning, Olbers had come to a strange conclusion: based on all that was known about the Universe at that time, the night sky should not have been dark.

Finite light in an infinite Universe

• Like many of his contemporaries, Olbers followed Isaac Newton and René Descartes in believing the Universe was infinite.
• If the Universe were finite and static, the force of gravity should draw all the stars together at a central point.
• But if the Universe stretched on forever, gravitational forces would on average be balanced in all directions.

A poet’s intuition

• On February 3 1848, he gave a public lecture about his ideas to 60 people at the New York Society Library.
• Poe’s audience at the New York Society Library did not give him the rapturous reception he had hoped for.
• It would be more than a century before scientists confirmed his intuitions about the enigma of the dark night sky.

Two and a half facts

In the first half of the 20th century many new theories of the cosmos were developed, spurred on by Einstein’s theory of general relativity, which explained gravity, space and time in new ways. In the second half of the century, these cosmological theories began to be tested with observations. In 1963, British astronomer Peter Scheuer argued that cosmology was based on only “two and a half facts”:
Strong controversies on the interpretation of facts 2 and 2.5 agitated the scientific community in the 1950s and 1960s. Was the Universe essentially stationary, or had it begun in an enormous explosion – a Big Bang? Supporters of both sides conceded, however, they needed to explain the darkness of the night sky.

The lifetime of stars

• He showed that the main factor determining the brightness of the night sky is actually the finite age of the stars.
• This limited number, each burning for a limited time, spread over a gigantic volume, lets darkness manifest itself between the stars.

Fossil light

• This fossil light should be observable today – but not with the naked eye, as the expanding Universe would have shifted it to longer wavelengths.
• Now measured with exquisite accuracy, the cosmic background radiation is the most common light in the Universe.
• We now know the cosmos is also illuminated by a second, much fainter background light, produced by galaxies as they form and evolve.

New answers, new questions

• We can now determine the number of stars in the sky with great accuracy.
