The answer to the ultimate question

That most famous of (former) British othello players, Aubrey, has apparently published a paper proving that the answer to the Hadwiger-Nelson Problem is not 4. Since I don't understand the question, let alone the answer, I'll have to take his word for it, but I do rather like the idea of there being a mathematical problem to which it was previously thought the answer might be 4, but is now known not to be. It's either 5, 6 or 7, the clever mathematicians now agree.
