Have you wondered why the sky at night is black? Professor Bob Nichol will be discussing the topic in this episode of the Research Futures webinar series. Our deepest images of the sky with space telescopes show that most of the sky remains without light. This trivial observation tells us something profound about the Universe and is known as Oblers' paradox.

Today, we know a lot about the Universe we live in, and have an answer to this paradox, but it is not the one we thought, or probably wanted.
