@Y not :”Doubts have recently arisen about the Big Bang itself”
True, thus the Big Bang “simply” as an effect of a cause…and so on.
Which reminds me the Deathless/the Unborn that is the highest Nibanna, which theoretically would be not an acausal Being but a an acausal Knowing.
For He knew that an acausal Being would be the supreme clinging,which would make “not clinging to nothing” even more difficult.
