SUMMARY

The current physics consensus acknowledges that while Einstein's theory of relativity supports the concept of a block universe, it does not necessitate it. Key figures like David Deutsch advocate for a quantum many-worlds interpretation, while Carlo Rovelli and Jan Dieks challenge the notion of block time. The prevailing agreement among physicists centers on the use of 4-dimensional spacetime for physical predictions, rather than a unified stance on the philosophical implications of the block universe.

PREREQUISITES
  • Understanding of Einstein's theory of relativity
  • Familiarity with the concept of 4-dimensional spacetime
  • Knowledge of quantum mechanics principles
  • Awareness of philosophical implications in physics
NEXT STEPS
  • Research the implications of Einstein's theory of relativity on time perception

  • Investigate Carlo Rovelli's views on relational quantum mechanics
  • Study the philosophical debates surrounding block time and the block universe
USEFUL FOR

Physicists, philosophy students, and anyone interested in the foundational concepts of time and space in modern physics.

What is the current physics consensus of the block universe?

I know its what Einsteins theory tells us and comes with relativity, Deutsch believes in a quantum many world block universe, but Rovelli and Dieks argue against block time?

Is block time still the main accepted theory of time we have...

Relativity is certainly consistent with the "block universe" view, but I don't think it *requires* that view. Relativity uses 4-dimensional spacetime as a model for making physical predictions; to the extent that there is a "consensus", I would say it's about that, not about any additional philosophical or metaphysical claims concerning the "block universe".

Also, as you point out, we know that relativity by itself, i.e., classical SR and GR, can't be a complete theory because it's not quantum mechanical, and there is certainly no consensus about the philosophical or metaphysical implications of quantum mechanics.
