Einstein CentennialAnswer
Can quantum entanglement send messages faster than light?
Einstein called it “spooky action at a distance,” and the matching is real, but here is why nobody can use it to send a message faster than light.

What did a 1926 letter change?
1926–2026: one hundred years since Einstein told Max Born that “the Old One” does not throw dice. The letter, the debate and the experiments that followed.

Einstein CentennialAnswer
Did Einstein lose his argument that God does not play dice?
A century after his famous letter to Max Born, experiments have ruled on part of Einstein’s hope, while the question of dice itself is still argued.
Einstein CentennialAnswer
Has Einstein’s relativity ever failed a test?
What happened to OPERA's 2011 faster-than-light claim, how relativity is tested, and why successful measurements do not prove every possible prediction.
Einstein CentennialAnswer
Is anything truly random?
Dice, coins and weather follow fixed rules we can’t track, but quantum events are different, and whether they are random at the deepest level is still argued.
Einstein CentennialAnswer
What did Einstein actually believe about God?
Einstein’s own letters and essays show a man who rejected a personal God, refused the atheist label, and felt deep awe at the order of nature.
Einstein CentennialAnswer
Why does quantum physics seem so weird, even to physicists?
Why electrons can produce wave-like patterns, what two-slit experiments show, and why a physical measurement differs from a conscious observer.

Is the Universe Truly Random?
A rolled die is unpredictable but not mysterious. Quantum events may be different. Here is where science draws the line, and where the debate begins.

How Scientists Tested Einstein’s Hunch
Einstein suspected quantum physics was hiding something. John Bell found a way to check, and decades of experiments gave a clear answer, with limits.

What Is Quantum Entanglement, and Why Did Einstein Call It Spooky?
Two particles can share one quantum state, even far apart. Here is what that means, why Einstein distrusted it, and why it still cannot carry a message.

Einstein vs. Bohr: The Debate Over What Quantum Physics Says Is Real
Einstein and Bohr agreed that quantum mechanics works, but they spent decades arguing about what it tells us is real, and the argument still echoes today.

The Dice Letter at 100: How One Sentence Shaped a Century of Physics
A century ago, Einstein told Max Born that "the Old One" does not throw dice, starting an argument that reshaped physics and is still not finished.
