Is It Time to Free Physics from Einstein's Legacy?

"Is it time to free physics from Einstein's legacy?"

Technically, "to free physics from Einstein's legacy" is easy - physicists denounce Einstein's 1905 constant-speed-of-light nonsense and relativity, entirely predicated on the nonsense, automatically collapses. The problem is that the idiocies (e.g. time travel) triggered by the nonsense are now inherent in the culture of our civilization - removing them may produce an incurable psychological trauma and greatly accelerate the decline of the civilization:

Thibault Damour: "The paradigm of the special relativistic upheaval of the usual concept of time is the twin paradox. Let us emphasize that this striking example of time dilation proves that time travel (towards the future) is possible. As a gedanken experiment (if we neglect practicalities such as the technology needed for reaching velocities comparable to the velocity of light, the cost of the fuel and the capacity of the traveller to sustain high accelerations), it shows that a sentient being can jump, "within a minute" (of his experienced time) arbitrarily far in the future, say sixty million years ahead, and see, and be part of, what (will) happen then on Earth. This is a clear way of realizing that the future "already exists" (as we can experience it "in a minute")."

The ideologues of the Einstein cult know that Einstein's physics is dead (exists in a zombie state) and are ready to jump into the bandwagon of the impending revolution (resurrection):

Dennis Overbye: "Is Albert Einstein finally dead? Yes. The old sage took his last breath and muttered his last indecipherable words, in German, on April 18, 1955. But lately he has been dying a second death, if one believes a new spate of articles and papers bemoaning the state of contemporary physics. Never mind the recent, staggering discovery of gravitational waves: ripples in space-time that Einstein predicted a century ago, and which indicate the universe is peppered with black holes that shred and swallow stars. Something much deeper than gravity or quantum theory, Einstein's other misbegotten legacy, is at stake."

This "something much deeper", actually the founding principle of modern physics, is the constancy of the speed of light Einstein postulated in 1905. The speed of light, as measured by the observer (receiver), either varies with the speed of the emitter (Newton's theory) or is invariable (ether theory and Einstein's relativity). Where is the truth? The answer was given, implicitly, in 1887. Variability proved directly. Invariability, "without recourse to contracting lengths, local time, or Lorentz transformations", disproved:

"Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether." Banesh Hoffmann, Relativity and Its Roots, p.92

Wikipedia: "Emission theory, also called emitter theory or ballistic theory of light, was a competing theory for the special theory of relativity, explaining the results of the Michelson–Morley experiment of 1887. [...] The name most often associated with emission theory is Isaac Newton. In his corpuscular theory Newton visualized light "corpuscles" being thrown off from hot bodies at a nominal speed of c with respect to the emitting object, and obeying the usual laws of Newtonian mechanics, and we then expect light to be moving towards us with a speed that is offset by the speed of the distant emitter (c ± v)."

Sabine Hossenfelder: Was Einstein wrong? Why some astrophysicists are questioning the theory of space-time

The speed of light is VARIABLE AS PER NEWTON, which implies that Einstein's spacetime does not exist and neither do LIGO's gravitational waves (ripples in spacetime):

Nima Arkani-Hamed: "Almost all of us believe that spacetime doesn't really exist, spacetime is doomed and has to be replaced..."

Philip Ball: "And by making the clock's tick relative - what happens simultaneously for one observer might seem sequential to another - Einstein's theory of special relativity not only destroyed any notion of absolute time but made time equivalent to a dimension in space: the future is already out there waiting for us; we just can't see it until we get there. This view is a logical and metaphysical dead end, says Smolin."

"Was Einstein wrong? At least in his understanding of time, Smolin argues, the great theorist of relativity was dead wrong. What is worse, by firmly enshrining his error in scientific orthodoxy, Einstein trapped his successors in insoluble dilemmas..."

Nobel Laureate David Gross observed, "Everyone in string theory is convinced...that spacetime is doomed. But we don't know what it's replaced by."

What scientific idea is ready for retirement? Steve Giddings: "Spacetime. Physics has always been regarded as playing out on an underlying stage of space and time. Special relativity joined these into spacetime... [...] The apparent need to retire classical spacetime as a fundamental concept is profound..."

"Rethinking Einstein: The end of space-time. [...] Horava, who is at the University of California, Berkeley, wants to rip this fabric apart and set time and space free from one another in order to come up with a unified theory that reconciles the disparate worlds of quantum mechanics and gravity - one the most pressing challenges to modern physics."

"We've known for decades that space-time is doomed," says Arkani-Hamed. "We know it is not there in the next version of physics."

"This space-time picture has now been on the throne for over 100 years, and has so far vanquished all pretenders to its crown. The discovery of gravitational waves in 2015 was a decisive victory, but, like its predecessors, it too might be about to fall. That's because it is fundamentally incompatible with the other big beast in the physics zoo: Quantum theory."

OK, space-time will go, all theoreticians are against it, but LIGO's "ripples in space-time" must remain, like the grin of the Cheshire Cat (otherwise LIGO fakers will have to go to jail):
