Relativity is inside the light cone phenomena, while Quantum Mechanics
is outside the light cone phenomena, dictated just by the scale (i.e.
whether we use classical/human scale or sub-atomic scale). This recent
paper [‘Quantum principle of relativity’; Andrzej Dragan,
Artur Ekert, New. J. Phys. 22 (2020) 033098] has shown that every
exotic Quantum effect like superposition, entanglement, probabilistic
behavior, multiple paths etc. can be explained just by allowing
super-luminal possibility. The ‘inside the light cone’ phenomena, and
the ‘outside the light cone’ phenomena together span the entire region
within the space and time axes. Only in unison they complete the entire
picture. We failed to realize that the same spacetime is getting split
into ‘space like’ and ‘time like’ regions based on scale. And the reason
behind this is not the magical (?) speed of light.
That would have turned both relativity and quantum mechanics into mere
branches of electromagnetism. The true reason is much deeper and at a
very fundamental level of our universe. It turns out
that the c is the radial expansion velocity of our
universe.
But why does the transition from Relativity to Quantum Mechanics happens
with decreasing size scale? That’s because, this is what is happens to
spatial and temporal dimensions at different scales:
3+1 (Classical regime) <=> 2+2 (Compton regime)
<=> 1+3 (Planck regime).
Just as space and time exchange roles at the event horizon of a Black
Hole, similarly, spatial and temporal dimensions switch roles for
extremely small scales (although due to a completely different
mechanism). Why this happens is difficult to expalin without the true
model of our universe. But, once explained, it becomes “Why didn’t I
think about it before? I was plain silly!”
From the center of universe viewpoint, simultaneity is absolute (as
demanded by Sagnac effect), and there is indeed absolute universal time
(as demanded by quantum mechanics). From our viewpoint (located at an
awkward position in the universe), locality is absolute, and velocity c
is the upper limit, and remains constant for every observer. This turns
(our) space and time into inseparable twins, and makes (our) time a
relative concept. This solves the time problem which had
so stubbornly resisted the reconciliation of Quantum Mechanics and
General Relativity.
Quantum Mechanics and Special Relativity are like two sides of the same
coin. But understanding the relation between Quantum Mechanics and
General Relativity is a bit tricky, because according to General
Relativity, gravity is the warping/curvature of the 4 dimensional
spacetime itself. At first sight, Quantum Mechanics and General
Relativity seem to be utterly incompatible! But actually, Special
Relativity’s big brother General Relativity only complicates things a
bit, but does not become inconsistent with Quantum Mechanics
altogether. The only difference between the warped spacetime of General
Relativity, and the flat spacetime of Special Relativity is very similar
to the difference between a stretched rubber membrane, with and
without a metal ball placed on it.
This paper does not sacrifice any of the spectacular success of
General Relativity and also does not compromise with any of the
stunningly accurate predictions of Quantum Mechanics. And yet, this
paper harmoniously brings Quantum Mechanics and General Relativity
together. Just bear in mind that Nature simply cannot afford to make our
two greatest theories incompatible. After all, both General Relativity
and Quantum Mechanics were based on what nature was actually telling us,
and nature herself would be accountable for any genuine contradiction
(but not for the breakdown of our physics due to our
misunderstanding!).
And, by the way, this paper solves some of the most pressing problems in
both Physics & Cosmology. The ‘Principle of Least Action’ which comes
closest to a ‘Theory of Everything’ arises as a direct consequence of
better SpaceTime theory proposed in this paper. Also, we can see why
the symmetries of nature (which gives rise to the crucial conservation
principles in Physics according to the Noether’s theorems) arises in the
first place.
