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...
 
Physics news on Phys.org
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.

Thread 'Can this experiment break Lorentz symmetry?'

1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...

Thread '1-Way Speed of Light'

Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...

Thread 'How can a black hole absorb matter?'

According to the General Theory of Relativity, time does not pass on a black hole, which means that processes they don't work either. As the object becomes heavier, the speed of matter falling on it for an observer on Earth will first increase, and then slow down, due to the effect of time dilation. And then it will stop altogether. As a result, we will not get a black hole, since the critical mass will not be reached. Although the object will continue to attract matter, it will not be a...
