Special relativity demands a locality principle (no instantaneous action at a distance); locality implies Bell’s theorem; quantum mechanics violates Bell’s inequality, therefore, quantum mechanics contradicts relativity!

What is the most significant problem with general relativity?
All masses and all sources of energy contribute to the curvature of spacetime, but we can only calculate the Earth-Sun orbit approximately, not exactly. This problem — the two-body problem in General Relativity — cannot be solved exactly.
Do quantum mechanics and relativity work together?
Quantum mechanics and the general theory of relativity form the bedrock of the current understanding of physics—yet the two theories don’t seem to work together. Physical phenomena rely on relationship of motion between the observed and the observer.
Why did Einstein disagree with quantum mechanics?
Einstein saw Quantum Theory as a means to describe Nature on an atomic level, but he doubted that it upheld “a useful basis for the whole of physics.” He thought that describing reality required firm predictions followed by direct observations.
How do general relativity and quantum mechanics conflict?
In theoretical physics, the problem of time is a conceptual conflict between general relativity and quantum mechanics in that quantum mechanics regards the flow of time as universal and absolute, whereas general relativity regards the flow of time as malleable and relative.
Which is correct general relativity or quantum mechanics?
In general relativity, events are continuous and deterministic, meaning that every cause matches up to a specific, local effect. In quantum mechanics, events produced by the interaction of subatomic particles happen in jumps (yes, quantum leaps), with probabilistic rather than definite outcomes.
Why does quantum mechanics contradict general relativity?
Quantum mechanics is incompatible with general relativity because in quantum field theory, forces act locally through the exchange of well-defined quanta.
What is the problem of general relativity?
The two-body problem in general relativity is the determination of the motion and gravitational field of two bodies as described by the field equations of general relativity. Solving the Kepler problem is essential to calculate the bending of light by gravity and the motion of a planet orbiting its sun.
What are the flaws of general relativity?
And experts have long suspected that general relativity can’t be right in realms of extremely high mass density. At the center of a black hole, for instance, the theory’s equations no longer make sense, because they imply that matter density would become infinite.
Why can’t quantum mechanics explain gravity?
There are simply too many possible configurations of both the interactions and the underlying space-time. We can’t make the math simple enough to solve; our mathematical models lose their predictive power.
Is general relativity proven?
Tests of general relativity General relativity has also been confirmed many times, the classic experiments being the perihelion precession of Mercury’s orbit, the deflection of light by the Sun, and the gravitational redshift of light. Other tests confirmed the equivalence principle and frame dragging.
Who is the founder of quantum theory?
Max Planck, in full Max Karl Ernst Ludwig Planck, (born April 23, 1858, Kiel, Schleswig [Germany]—died October 4, 1947, Göttingen, Germany), German theoretical physicist who originated quantum theory, which won him the Nobel Prize for Physics in 1918.
What did Albert Einstein say about quantum mechanics?
Albert Einstein famously said that quantum mechanics should allow two objects to affect each other’s behaviour instantly across vast distances, something he dubbed “spooky action at a distance”1. Decades after his death, experiments confirmed this.
What is Schrodinger’s cat trying to prove?
Schrodinger constructed his imaginary experiment with the cat to demonstrate that simple misinterpretations of quantum theory can lead to absurd results which do not match the real world.
Does time exist in quantum physics?
Time in quantum mechanics is rigid, not bendy and intertwined with the dimensions of space as in relativity. Furthermore, measurements of quantum systems “make time in quantum mechanics irreversible, whereas otherwise the theory is completely reversible,” said Renner.
Does time exist at quantum level?
According to quantum mechanics, the answer appears to be “no”, and time appears to be in fact smooth and continuous (contrary to common belief, not everything in quantum theory is quantized).
Does time exist in quantum gravity?
Time is absolute in standard quantum theory and dynamical in general relativity. The combination of both theories into a theory of quantum gravity leads therefore to a “problem of time”.
Is quantum mechanics harder than general relativity?
GR is mathematically much more challenging than quantum, for the same level of understanding.
Does string theory unify quantum mechanics and general relativity?
String theory attempts to unify all four forces, and in so doing, unify general relativity and quantum mechanics. At its core is a fairly simple idea—all particles are made of tiny vibrating strands of energy.
What is the theory of quantum gravity?
Quantum gravity (QG) is a field of theoretical physics that seeks to describe gravity according to the principles of quantum mechanics, and where quantum effects cannot be ignored, such as in the vicinity of black holes or similar compact astrophysical objects, and where the effects of gravity are strong, such as …
Does time really exist?
Does time exist? The answer to this question may seem obvious: of course it does! Just look at a calendar or a clock. But developments in physics suggest the non-existence of time is an open possibility, and one that we should take seriously.
Does time not exist?
According to Rovelli, time emerges in the thermodynamic context, but it is an illusion born of our incomplete knowledge; it is not something that exists objectively. “Time is a derived concept, it is not something fundamental,” Rovelli summarises to OpenMind.
Do time crystals exist?
Lazarides acknowledged that the current experiments with time crystals are far from any practical applications, whatever they might be, but the chance to learn more about quantum mechanics is invaluable. Time crystals are “something that doesn’t actually exist in nature,” he said.
Where does the theory of relativity fail?
At the center of a black hole, for instance, the theory’s equations no longer make sense, because they imply that matter density would become infinite. Traveling to the interior of a black hole to test general relativity would be a poor strategy, for many reasons.
Where does Einstein’s theory of relativity fail?
As far as it has been tested in orbits of satellites and in the cosmological observations the theory of General Relativity is validated. Where it fails is when one pushes the mathematical construct to the extreme, for example : point elementary particles as in the current standard model.
