What does the time reversibility of the laws of physics mean for causality?
Does the fact that the fundamental laws are symmetric with respect to direction of time show that causation does not exist? Since causality always requires the cause to precede the effect, but laws of ...

Could our physical universe be time-irreversible?
Suppose that in our universe, there were two initial states which lead to the same outcome state after one time step. How could we possibly remember which of the two steps we came from if the ...

Entropy of a deterministic reversible system
Suppose a deterministic reversible system evolving from state A of gas located in a small bottle in an otherwise empty room, to state B where the gas is dispersed throughout the room.
Why is the ...

If I add one particle to the system at a time, When does the time reversal symmetry breakdown?
Suppose I have a system in my mind which consists of two elementary particles interacting with each other via fundamental interactions. We know that fundamental interactions have $T$-symmetry and ...

Reversibility of Physical Process : QM vs CM
It is often stated that the processes in quantum mechanics are reversible as they follow the Schrodinger's Equation : $$ - \frac{\hbar^2}{2m} \nabla^2 \Psi(x,t) + V(x,t)\ \Psi(x,t) = i \hbar\ \frac{\...
