Wow, that's quite a jump. Since I can remember following the topic the jumps in estimated age were getting smaller and smaller as measurements were getting more and more precise. So this is a bit mind-blowing if true.

The tired light hypothesis has been fringe for decades. This is an interesting application of it, but this paper isn't going to be accepted without some rather vigorous challenge. It'll be years of new observations and dozens of new studies re-examining already published data before the dust settles on this.
