Depending on where we look, the universe is expanding at different rates. Now, scientists using the James Webb and Hubble space telescopes have confirmed that the observation is not down to a measurement error.

    Isn’t it more likely that one, or both, ways of measuring are wrong? As in, they’re not useful for measuring the universe’s rate of expansion?

    Now, scientists using the James Webb and Hubble space telescopes have confirmed that the observation is not down to a measurement error.

    I’m trying to understand the distinction you are making. Could you elaborate?

      Not a scientist but the article seems to mean that they checked that the tools themselves had no defects giving incorrect measurements.

      This comment seems to be questioning the methodology of how we measure the rate of expansion so tackles a different aspect of the conversation.

      But that’s about as much as I can contribute haha
