    Somewhat. Based on my understanding of current astronomy news (I’m not an astronomer, just interested in the field) it’s not proven, but it’s not entirely disproven either. For instance, my understanding is that the Hubble constant (rate of expansion of the universe) is different if measured with the Cosmic Microwave Background (newer universe) compared to measuring redshirt of stars (older universe). Of course, it could be that one of the measurements made an assumption that’s not true, but i don’t think it’s out of the question that the false assumption ends up being that the constant stays the same over time…

    Take what I say with a grain of salt, though. Hopefully an actual astronomer can pitch in
