The block universe model, a popular interpretation of special relativity, has come under fire from cosmologists who argue it fails to capture the true nature of time. In a recent discussion, physicist George Ellis pointed out that general relativity, which governs the large-scale structure of the universe, introduces preferred time sections that the block universe ignores.
Cosmological evidence shows that space-time itself is expanding, creating a global direction of time that contradicts the static, four-dimensional block. Ellis emphasizes that the universe is evolving, not frozen. The block universe argument, he says, is fundamentally flawed when applied to real cosmology.
