Event description

Description

We will explain the concept of the expanding universe -- what exactly is expanding? -- and the modern evidence for it. This will reveal a number of unexpected connections between the size and age of the universe and the conditions needed for life to exist and persist within it. We will meet the idea that an inflationary surge in expansion rate of the universe occurred in the distant past and see the powerful evidence that this happened. This will provoke us to take seriously the idea that we are part of a multiverse of universes, each with different properties, and that our observable universe might have a beginning whilst the multiverse does not. Finally, we will see what the observed acceleration of our universe's expansion today signals about its far future. It may well be that astronomers in the far future will not be able to study the universe by direct observation like we do today.
