Can you guess the word in this puzzle, which relates to a recent Physics World article?

Here’s how the game works:

• Enter a word guess – in this game the word has six letters.
• After submitting your guess, each letter in the guessed word is coloured to provide feedback:
• Green:The letter is correct and is in the correct position in the target word.
• Yellow:The letter is correct but is in the wrong position in the target word.

• Grey:The letter is not in the target word at all.

• Using this colour feedback, refine your next guess.

• Continue guessing until you correctly identify the hidden word(s) or run out of attempts.
