Could the big cold spot in the CMBR map be a sign that almost all radiation from that direction has already passed us, and that be a sign that the end of the universe is closest to earth in that direction?

    $\begingroup$ I have to say I'm not into physics but fascinated by cosmological hypotheses. Nevertheless the cold spot seems to be part of well established astrophysics, see for instance telegiz.com/articles/23750/20170519/… $\endgroup$

    $\begingroup$ There isn't an end/edge of the universe in the sense you mean it. $\endgroup$ Commented Jun 30, 2022 at 13:10

    $\begingroup$ Even the professionals are divided on the question whether there is some end or edge to the universe and how to define it. quora.com/Does-the-universe-have-an-edge?share=1 is a thread on that topic. $\endgroup$
