Is Cosmology in Crisis?

BBC Four - The Sky at Night, Is Cosmology in Crisis?

We know that distant galaxies are racing away from us. But just how fast is the Universe expanding? Scientists are yet to agree on an answer.

Ever since we discovered that distant galaxies are racing away from us, there has been a heated debate over just how fast the Universe is expanding.

At the beginning of the 21st century, we thought we knew the answer. But now, two very different viewpoints have emerged. And they are dividing the scientific community.

The Sky at Night meets leading astronomers and cosmologists on both sides of the debate. Which team has the right answer? Or could both
teams be right? If so, we may need to rethink everything we think we know about the Universe.

Knowledge, arts, music and culture from the UK and the world.

BBC Four reflects arts, music and culture with an ambitious range of intellectually and culturally enriching programmes, taking an expert and in-depth approach to its subjects.
