Astrophysics claims that the Universe is expanding. It believes this because of some spectroanalysis on light emanating from very tiny spots seen through telescopes. That should tell us all we need to know about Astrophysics and humanist orthodoxy, but there is a proof that they don’t know,
If the Universe expands, then it must expand from someplace, a fixed point. If there is a fixed point and if there is an expansion, then there must also be a limit or a border. Neither of these two are known or knowable.
