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.

Internal opposition in Einstein cult puts the blame on string theorists and multiverse not-even-wrongsters for the death of physics:

Peter Woit: "If, as seems increasingly all too possible, we're now at an endpoint of fundamental physics, with the field killed off by a pseudo-scientific argument ("no point in continuing, the multiverse did it"), Arkani-Hamed is one of those who will be most responsible for the situation." http://www.math.columbia.edu/~woit/wordpress/?p=9444

Peter Woit: "I think the worst thing that has happened to theoretical physics over the past 25 years is this descent into ideology, something that has accelerated with the multiverse mania of the last 10-15 years." http://www.math.columbia.edu/~woit/wordpress/?p=9375

The "descent into ideology" is a fact but the number 25 is incorrect - it should be replaced by 113:

"This paper investigates an alternative possibility: that the critics were right and that the success of Einstein's theory in overcoming them was due to its strengths as an ideology rather than as a science. The clock paradox illustrates how relativity theory does indeed contain inconsistencies that make it scientifically problematic. These same inconsistencies, however, make the theory ideologically powerful. [...] The gatekeepers of professional physics in the universities and research institutes are disinclined to support or employ anyone who raises problems over the elementary inconsistencies of relativity. A winnowing out process has made it very difficult for critics of Einstein to achieve or maintain professional status. Relativists are then able to use the argument of authority to discredit these critics. Were relativists to admit that Einstein may have made a series of elementary logical errors, they would be faced with the embarrassing question of why this had not been noticed earlier. Under these circumstances the marginalisation of antirelativists, unjustified on scientific grounds, is eminently justifiable on grounds of realpolitik. Supporters of relativity theory have protected both the theory and their own reputations by shutting their opponents out of professional discourse. [...] The triumph of relativity theory represents the triumph of ideology not only in the profession of physics bur also in the philosophy of science." Peter Hayes, The Ideology of Relativity: The Case of the Clock Paradox http://www.informaworld.com/smpp/content~content=a909857880

And when ideology replaces science, bureaucrats replace scientists of course:

Mike Alder: "It is easy to see the consequences of the takeover by the bureaucrats. Bureaucrats favour uniformity, it simplifies their lives. They want rules to follow. They prefer the dead to the living. They have taken over religions, the universities and now they are taking over Science. And they are killing it in the process. The forms and rituals remain, but the spirit is dead. The cold frozen corpse is so much more appealing to the bureaucratic mind-set than the living spirit of the quest for insight. Bureaucracies put a premium on the old being in charge, which puts a stop to innovation. Something perhaps will remain, but it will no longer attract the best minds. This, essentially, is the Smolin position. He gives details and examples of the death of Physics, although he, being American, is optimistic that it can be reversed. I am not. [...] Developing ideas and applying them is done by a certain kind of temperament in a certain kind of setting, one where there is a good deal of personal freedom and a willingness to take risks. No doubt we still have the people. But the setting is gone and will not come back. Science is a product of the renaissance and an entrepreneurial spirit. It will not survive the triumph of bureacracy. Despite having the infrastructure, China never developed Science. And soon the West won't have it either." https://www.highbeam.com/doc/1G1-172684821.html

Leonard: "I know I said physics is dead, but it is the opposite of dead. If anything, it is undead, like a zombie."
