OK, thanks. The article made it sound like they found a way to show time reversal symmetry breaking and I was waiting for them to drop whatever assumption they used to get there. The underlying theory is symmetric and so it only makes sense that it's just a limitation on numerics.
- mcguire 7y ago"...a limitation on numerics." My understanding is that measuring quantities smaller than the Planck limits is problematic. (IIRC, the energy of a photon needed to make the measurement is large enough to create a black hole.) As a result, it's not just "numerics"; the theory may be symmetric, but the physical system cannot be observed to be.
