Space merged with time and being ‘curved’ is one of the great mysticisms from the Church of ‘The Science’. It is nonsense of course. See the quote aboe. Einstein knew it was a fable. He even admitted that the universe is Euclidean, not a geometrically curved dimension.
The merger of space with time is one of the great deceptions in ‘The Science’. The 2 concepts have nothing to do with each other. They are merged to correct errors in Relativity’s maths, and to compensate for the very weak force that is gravity, and to explain how planets over billions (soon trillions?) of Darwinian years, serenely glide around their ‘star’.
