A chronon is a proposed quantum of time, that is, a discrete and indivisible "unit" of time as part of a hypothesis that proposes that time is not continuous. In simple language, a chronon is the …

Jul 11, 2024 · Physicists have struggled to understand the nature of time since the field began. But a new theoretical study suggests time could be an illusion woven at the quantum level.

Feb 22, 2025 · Scientists have uncovered a fascinating possibility: time at the quantum level may not be strictly one-way. While our everyday experiences make time seem irreversible, …

5 days ago · Quantum clocks built from randomness offer a new perspective on time, merging quantum mechanics with timekeeping and challenging classical physics concepts.

Feb 27, 2025 · Scientists studying a centuries-old mystery of physics suggest two “arrows of time” control the evolution of quantum systems. If a cup of water spills on the floor, the water can’t …

In theoretical physics, the problem of time is a conceptual conflict between quantum mechanics and general relativity.

According to quantum mechanics, the answer appears to be “no”, and time appears to be in fact smooth and continuous (contrary to common belief, not everything in quantum theory is …

In mathematical physics, the concept of quantum spacetime is a generalization of the usual concept of spacetime in which some variables that ordinarily commute are assumed not to …

This means that while a time traveler can influence past events, those influences must ultimately lead to a consistent historical narrative. However, Novikov's self-consistency principle has …

Aug 4, 2025 · In the physical world, time marches in one direction, but things aren’t so straight forward in the quantum realm. Researchers have discovered that it’s possible to speed up, …
