The Missed Conversation
Einstein died nine years before John Stewart Bell published his 1964 theorem. Bell's theorem shows that no local hidden-variable theory—given standard assumptions such as measurement independence—can reproduce all the predictions of quantum mechanics. Many physicists read this as establishing some form of quantum non-locality. If Einstein had lived to see Bell's work experimentally verified, he would have faced a sharper version of a choice he already disliked:
A Forced Choice
Accept 'spooky action at a distance' inside a rigid Block Universe, or take seriously a preferred causal rest frame (NeoLET) that offers a structure for simultaneous events. (These are not the only options—many-worlds, superdeterminism, and other readings exist too—but they frame the tension this page cares about.)
That is one of the deep interpretive problems in modern physics. Not the mathematics—everyone agrees the mathematics works. The open question is the interpretation: what reality is underneath the equations.
Why I Refuse to Shut Up and Calculate
There is a widespread attitude in parts of physics that can feel almost like a commandment: "Shut up and calculate." The idea is that interpretive questions are philosophically messy, that they don't change the predictions, and that physicists should focus on what works mathematically.
I understand why that philosophy exists, and it has been useful. But I think it can also become a way of sidestepping questions that genuinely matter.
If two interpretations make the same predictions, and one of them tells you that your sense of free will is an illusion—that your future is already written into the static geometry of spacetime—while the other preserves an open universe where genuine becoming occurs, then the choice between them matters. It matters existentially. It matters philosophically. And it matters to how we understand ourselves.
Bell's Suggestion
John Stewart Bell himself was not satisfied with the standard Copenhagen interpretation of quantum mechanics. He understood that there was a problem lurking beneath the mathematical success. And in his later work, he made a remarkable suggestion.
Revisiting the Ether
Bell suggested that perhaps the idea of an ether—a preferred reference frame—should be revisited. Not the classical ether of the 19th century, but a modern understanding of what a preferred frame could mean in a quantum context.
You can read Bell's thoughts directly. In the Bell-Davies paper, look for the passage where Bell discusses why the ether deserves another look—in the copy linked below it falls around page 49, though exact pagination varies by edition, so read for the discussion itself rather than the page number.

This is significant. Bell was not a crackpot chasing fringe ideas; he was one of the most rigorous theoretical physicists of the 20th century. He dared to ask a question the rest of the field had largely ignored: what if we threw away something vital when we abandoned the concept of a preferred frame?
His foundational 1964 work set the stage for our modern understanding of quantum reality, and he died in 1990 at just 62, long before the later Nobel recognition of the experimental program built around Bell tests. In 2022, the Nobel Prize in Physics was awarded to Alain Aspect, John Clauser, and Anton Zeilinger for landmark experiments on entangled photons that established Bell inequalities as a central part of modern physics. Their recognition does not diminish Bell's role; it underlines how much of the later experimental story grew out of his theoretical work.
The Structure of the Problem
The structure of this problem is not new. It goes back to the foundations of relativity itself. Einstein made a choice about how to synchronize clocks across distances. That choice was mathematically elegant and it worked. But it was not the only possible choice.
If you make a different choice about synchronization—one that permits a preferred rest frame—you can still reproduce all the tested predictions of Special Relativity. You can still make sense of quantum mechanics. But now you have room for an objective present and a genuinely open future. (How much room that choice really leaves is itself debated: David Malament argued that standard synchronization is uniquely picked out by the causal structure plus an inertial worldline, and the question has stayed open rather than closed. This page takes the conventionalist side of a live dispute, not a settled result.)
That is what NeoLET proposes. Not a rejection of relativity. Not a rejection of quantum mechanics. But a reinterpretation of both, grounded in a choice that Einstein could have made but didn't.
Why This Matters Now
The philosophical picture we accept shapes how we see ourselves. If physics tells us we live in a completed 4D block, then free will appears illusory. Our sense that we are genuine agents in an unfolding world becomes suspect.
But if physics is agnostic about this—if two equally valid interpretations point in opposite directions—then we are free to choose based on reason, evidence, and what makes sense of human experience.
I believe the second picture is more honest. I believe it is also more aligned with reality.
