3 days agoSo “tired light” could explain redshift, light that loses energy over time, but where would that energy be going? Heat loss somehow? Energy can’t be destroyed according to our current understanding so I’m not sure I understand the mechanism of decay
I think in the dark matter/expansion model the idea is that light is stretched due to the universe itself expanding, but maybe I misunderstood the premise. Regardless of the veracity of the dark matter model, the original question of the mechanism of loss is still relevant I think.
