Sean Carroll: Quantum mechanics is the wonderfully successful theory of how the world behaves at the microscopic level, while on large scales space and time are wedded together in Einstein's famous general theory of relativity. Reconciling how both of these ideas can be true at the same time has been a longstanding puzzle for theoretical physicists. Recently, we have been bringing new tools to bear: information theory, the many-worlds interpretation of quantum mechanics, and an improved understanding of black-hole entropy. The time is right to finally figure out the quantum ingredients out of which space and time are made. https://www.nbcnews.com/mach/science/15-top-science-tech-leaders-offer-surprising-predictions-2018-ncna814196
That is, Sean Carroll and brothers Einsteinians will continue to reconcile irreconcilable concepts - Newton’s absolute time and Einstein’s idiotic spacetime:
"The effort to unify quantum mechanics and general relativity means reconciling totally different notions of time. In quantum mechanics, time is universal and absolute; its steady ticks dictate the evolving entanglements between particles. But in general relativity (Albert Einstein's theory of gravity), time is relative and dynamical, a dimension that's inextricably interwoven with directions X, Y and Z into a four-dimensional "space-time" fabric." https://www.quantamagazine.org/20161201-quantum-gravitys-time-problem/
Perimeter Institute: "Quantum mechanics has one thing, time, which is absolute. But general relativity tells us that space and time are both dynamical so there is a big contradiction there. So the question is, can quantum gravity be formulated in a context where quantum mechanics still has absolute time?" https://www.perimeterinstitute.ca/research/conferences/convergence/roundtable-discussion-questions/what-are-lessons-quantum
In 2018, by developing other idiotic concepts - information, many-worlds and black-hole entropy - Sean Carroll and brothers Einsteinians will make the death of physics irreversible.
