to be flooded with an infinite amount of light from all these stars. The obvious lack of this infinite light from space is known as Olbers’ paradox. There are various ways to explain why the night sky is not infinitely bright, but the Big Bang explanation is perhaps the most convincing. If

we will have to travel to the furthest reaches of the Universe and explore the essence of space and time themselves. Hold on tight. 3 OLBERS’ PARADOX Why does it get dark at night? Several years ago I was on holiday with my family and a group of friends in France. We

significant than it first appears. Indeed, astronomers puzzled over it for hundreds of years before they found the correct answer. It is known today as Olbers’ Paradox. Here, then, is the problem. We have good reason to believe that even if the Universe is not infinite in size (and it may well

astronomers even seemed interested in it until then. In 1952 the great Anglo-Austrian cosmologist Hermann Bondi published an influential textbook in which the term “Olbers’ Paradox” was coined for the first time. But as we shall see, the attribution was misplaced, for Olbers was not the first to pose the problem

to worry about it, of course. PROOF OF THE BIG BANG Understanding that the Universe is expanding is actually enough to enable us to solve Olbers’ Paradox—but let’s go one important step further and prove that it is expanding because there must have been a Big Bang. Apart from the

quote the three standard pieces of evidence I discussed earlier. But isn’t it so much easier, and in my view more persuasive, to turn Olbers’ Paradox on its head? Rather than saying that the reason it gets dark at night is that the Universe must have had a beginning and that

Olbers’ paradox (named after the German astronomer Heinrich Wilhelm Olbers) states that if the Universe is infinitely old and unmoving then every direction you look in should

, there must be an infinite amount of light entering our eyes from all directions. The night sky should be white, not black. This is called Olbers’ paradox. Some of the greatest minds in history have tried to tackle this sticky question. Kepler, for example, dismissed the paradox by claiming that the universe

invented and forgotten. Also, the natural assumption that faraway shining objects are uniformly distributed in space was analyzed and shown to lead to the embarrassing Olbers paradox, which argues that the sky must be uniformly and infinitely bright. A way to avoid this paradox was proposed by a science fiction writer, Edmund
