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.

At last, the truth is out. What everyone knew all along is now a scientific fact: when it comes to the offside rule, referees and linesmen are blind.

At last, the truth is out. What everyone knew all along is now a scientific fact: when it comes to the offside rule, referees and linesmen are blind.

In a report in the British Medical Journal a Spanish doctor, Francisco Belda Maruenda, says the human eye is physiologically unable to process all the information needed to apply the rule correctly. They must be able to keep at least five moving objects in their visual field at the same time - two players from the attacking team, two from the defending team, as well as the ball - in order to make a fully informed decision.

Dr Maruenda said this was beyond the capacity of the human eye - "especially as these five objects can be anywhere within the defenders' half of the pitch, an area of up to 2,000 square metres. This may explain why so many offside decisions are controversial and why television replays of a game clearly show that the offside rule was not properly enforced."

His conclusion? Modern technology, such as freeze-frame television and frame-by-frame analysis. Until then, we're all in the dark.
