Default String Theorists Repudiate Einstein's Relativity

"Splitting Time from Space - New Quantum Theory Topples Einstein's Spacetime. Buzz about a quantum gravity theory that sends space and time back to their Newtonian roots. Was Newton right and Einstein wrong? It seems that unzipping the fabric of spacetime and harking back to 19th-century notions of time could lead to a theory of quantum gravity. [...] But now Petr HoĊ™ava, a physicist at the University of California, Berkeley, thinks he understands the problem. It's all, he says, a matter of time. More specifically, the problem is the way that time is tied up with space in Einstein's theory of gravity: general relativity. Einstein famously overturned the Newtonian notion that time is absolute - steadily ticking away in the background. Instead he argued that time is another dimension, woven together with space to form a malleable fabric that is distorted by matter. The snag is that in quantum mechanics, time retains its Newtonian aloofness, providing the stage against which matter dances but never being affected by its presence. These two conceptions of time don't gel." https://www.scientificamerican.com/a...me-from-space/

Time is tied up with space in Einstein's SPECIAL relativity, Petr Horava, not in "Einstein's theory of gravity: general relativity". So "splitting time from space" presupposes declaring that the underlying premise that ties time to space, Einstein's constant-speed-of-light postulate, is false.

Of course, neither Horava nor any other "theoretician" cares about whether Einstein's spacetime is true or not. They are all scavengers that feed on the remnants of the dead physics. If repudiating Einstein's relativity will provide them with more carrion, they will repudiate it. If not, not.
