We won’t know for sure until we bring the samples back.
What a phenomenal amount of work goes into this place. There’s always something to watch, something to learn. I’ve never seen the YouTube channel or Universe Today website, but it’s been so worthwhile joining the Patreon channel. I just love how active it is and in particular I love the question show.
Love the long videos 😀
There were a couple of different metrics for dark energy that were mentioned here and it wasn't quite clear which was used where. There is the total amount of dark energy, and also the amount that is added as space expands. I presume everything is saying that the total is increasing, but although you mentioned that one study found the rate was decreasing, it was unclear if you were comparing them to studies of the total increase or the rate.
