Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Your support makes all the difference.

Jim Al-Khalili's new two-part physics documentary Light and Dark had a scope that seemed just a little ambitious for two hours of television. "Light and Dark is essentially the story of everything we know and everything we don't know about our universe." So that's pretty much everything, then, Jim? Yet rather than the confusion of ideas you might expect, Al-Khalili's documentary illuminated a scientific story with its own, rather beautiful, internal logic.

We began with Euclid's 3rd-century BC discovery that light moves in straight lines, and continued chronologically, through Galileo's paradigm-shifting invention of the telescope and Newton's experiments with prisms. In the past 30 years, said Al-Khalili, we have looked out into the Universe and seen as far as it's possible to see, in both space and time.

And there we might have reached a comfortable conclusion, were it not for part two next week and this intriguing tease: "The vast majority of the cosmos can't be seen at all... and by exploring that darkness, we've come to realise that we've seen virtually nothing." That's the trouble with these physics documentaries: the more you learn, the less you understand.
