Now don’t you go right past
you mustn’t drive too fast
The future affects the past

Are both perhaps present in time future
And time future contained in time past.”

3. The Important Big Picture
Problems
How do we unify Einstein’s general relativity of the
gravitational field with the quantum field theory of the
electro-weak and strong forces?
Is time travel to the past through wormhole stargates
possible?
See Cal Tech’s Kip Thorne’s movie Interstellar for
example where this question is explored in a
“science-faction” pop way.
What is consciousness? How can we explain our self-
awareness in a scientific way? This is David
Chalmer’s “hard problem.”
How real is real? For example, do we live in a
hologram simulation? See Nick Bostrum’s book on
advanced super-intelligence for example.
Are we alone in the multi-verse?
What about God?
4. “God does not play dice with the universe.”
As Albert Einstein said “God does not play dice
with the universe” we can now arrive at a post-
quantum view of things and say “He loads the
dice back from the future”.
Future events are contributory causes of present
ones – Past (Causality) is interacting with our
Future (Retro-Causality) at the junction of the
present moment called the ‘now’ moment
5. FEELING THE FUTURE: IS
PRECOGNITION POSSIBLE?
MOST SCIENCE PAPERS don’t begin with a
description of psi, those “anomalous processes of
information or energy transfer” … It’s even less
common for a serious science paper, published in
an elite journal, to show that psi is a real
phenomenon. But that’s exactly what Daryl Bem
of Cornell University has demonstrated in his new
paper, “Feeling the Future: Experimental
Evidence for Anomalous Retroactive Influences
on Cognition and Affect,” which was just
published in The Journal of Personality and
Social Psychology.

6. Back From the Future
A series of quantum experiments shows that
measurements performed in the future can
influence the present. Does that mean the
universe has a destiny—and the laws of physics
pull us inexorably toward our prewritten fate?

This article is about the work of David Bohm’s
protégé Yakir Aharonov and his students on the
interference of future to present “destiny”
quantum information flows with past to present
“history” quantum information flows to create
“weak measurements” in the present that have
useful laboratory applications.

8. CAUSALLY SYMMETRIC BOHM
MODEL
Roderick I. Sutherland
Centre for Time, Department of Philosophy,
University of Sydney, NSW 2006 Australia
“A version of Bohm’s model incorporating
retrocausality is presented, the aim being to
explain the nonlocality of Bell’s theorem while
maintaining Lorentz invariance in the underlying
ontology. The strengths and weaknesses of this
alternative model are compared with those of the
standard Bohm model.”
9. Free Will and Retrocausality in the
Quantum World
A conference held under the auspices of the JTF-
funded project, New Agendas for the Study of
Time
Venue: Free Will and Retrocausality in the
Quantum World
Winstanley Lecture Theatre, Trinity College,
Cambridge
Dates: 1—4 July 2014
10. Why retrocausality — and why
free will?
“The 'classic' motivation for retrocausal models in
QM stems from Bell's Theorem, and the
nonlocality it seems to entail. Nonlocality is often
felt to be counterintuitive in itself, and the source
of an unresolved tension between quantum
theory and special relativity. As Bell himself
described the implications of his famous result:
‘[I]t's a deep dilemma, and the resolution of it will
not be trivial ... [T]he cheapest resolution is
something like going back to relativity as it was
before Einstein, when people like Lorentz and
Poincaré thought that there was an aether — a
preferred frame of reference — but that our
measuring instruments were distorted by motion
in such a way that we could not detect motion
through the aether’.’’
11. No!
Backward in Time Entanglement?
Yes!
John Archibald Wheeler and Richard Feynman introduced
future to past electromagnetism back in the 1940s in such
a way as to be consistent with the apparent lack of
precognition.
Olivier Costa de Beauregard in Paris applied their idea to
quantum theory in the 1950s and showed that the
apparent faster than light quantum entanglement is really a
“Feynman zig-zag” involving future-to-past combined with
past-to-future quantum information flows.
This is consistent with Einstein’s key idea behind special
relativity. There is no need for the preferred frame of
reference. Indeed Sutherland has shown how to
incorporate this into Bohm’s theory.
Many physicists since then further developed this basic
idea including I.J. Good, Fred Hoyle, Yakir Aharonov, John
Cramer, Sheldon Goldstein and their students, Henry
Stapp, Roger Penrose, Huw Price, Ken Wharton, Fred
14. Back-From-The Future Influence
“As Bell was well aware, the dilemma can be avoided if the
properties of quantum systems are allowed to depend on what
happens to them in the future, as well as in the past. Like most
researchers interested in these issues, however, Bell felt that the
cure would be worse than the disease — he thought that this
kind of “retrocausality” would conflict with free will, and with
assumptions fundamental to the practice of science. (He said
that when he tried to think about retrocausality, he “lapsed into
fatalism”.)
If this objection to retrocausality in QM is well-founded, it raises
interesting issues about the nature and origins of this "free will",
that turns out to play such a surprising role in the foundations of
physics. If the objection is not well-founded, then it is high time it
is moved aside, so that the retrocausal approach can be given
the attention it otherwise seems to deserve.”

15. Henry Dwight Sedgwick, Victorian Gentleman,
Harvard Porcellian Club wrote:
“Science proceeds as if the past was the home of
explanation; whereas the future, and the future alone,
holds the key to the mysteries of the present. When
the first cell divided, the meaning of that division was
to be discovered in the future, not in the past; when
some pre-human ancestor first uttered a human
sound, the significance of that sound was to be
interpreted by human language, not by apish grunts;
when the first plant showed solicitude for its seed, the
interest of that solicitude lay in the promise of
maternal affection. Things must be judged in the light
of the coming morning, not of the setting stars”. -
Henry Dwight Sedgwick, “An Apology for Old Maids” (
1908)
16. “Creation faces the future”
“There are invisible ways of conveyance by which
some great thing doth touch our souls, and by which
we tend to it. Do you not feel yourself drawn by the
expectation and desire of some Great Thing?” -
Henry Dwight Sedgwick, “The House of
Sorrow” (1908)
‘It is not the past which, like an uncoiling spring,
pushes us on; creation faces the future, and is drawn
onward by an irresistible attraction. “For though it be a
maxim in the schools,” says Thomas Traherne, “that
there is no love of a thing unknown, yet I have found
that things unknown have a secret influence on the
soul, and, like the centre of the earth unseen, violently
attract it. We love we know not what…”
- H D Sedgwick
17. Sir James Jeans
“The stream of knowledge is heading towards a non-
mechanical reality; the Universe begins to look more
like a great thought than like a great machine. Mind
no longer appears to be an accidental intruder into the
realm of matter... we ought rather hail it as the creator
and governor of the realm of matter.” The Mysterious
Universe, page 137.
“I incline to the idealistic theory that consciousness is
fundamental, and that the material universe is
derivative from consciousness, not consciousness
from the material universe... In general the universe
seems to me to be nearer to a great thought than to a
great machine. It may well be, it seems to me, that
each individual consciousness ought to be compared
to a brain-cell in a universal mind.”

21. Niels Bohr to Wolfgang Pauli
1958
“We are all agreed that your theory is crazy. The
question which divides us is whether it is crazy
enough to have a chance of being correct. My own
feeling is that it is not crazy enough.”
“cosmology without apology
no-one knows the topology
only craziness will find the way
breaking down the rulebooks of today
smashing beliefs is half the job
stealing the future just to rob
the meaning of the universe will be clear
when we find a route from here to there”
Excerpt from Richard Fordham’s song.
22. Stephen Hawking, A Brief History of
Time
“... if we do discover a complete theory, it should
in time be understandable in broad principle by
everyone, not just a few scientists. Then we shall
all, philosophers, scientists, and just ordinary
people, be able to take part in the discussion of
the question of why it is that we and the universe
exist. If we find the answer to that, it would be the
ultimate triumph of human reason - for then we
would know the mind of God.”

special relativity in 1961 at Brandeis University before it
became mainstream, but I was told to “shut up and
calculate.”

24. Einstein’s ‘Spooky Physics’ Gets More Entangled
by Clara Moskowitz | June 03, 2009
Quantum mechanics predicts that two or more
particles can become "entangled" so that even
after they are separated in space, when an action
is performed on one particle, the other particle
responds immediately. Physicists still don’t agree
how the particles send these instantaneous
messages to each other, but somehow, once they
are entwined, they retain a fundamental
connection.
This bizarre idea riled Einstein so much he called
it "spooky telepathic action at a distance.”
25. Two entangled mechanical oscillators
made up of two pairs of trapped ions.
When one pair was forced to change its movement, the other
pair did as well.
26. Quantum Field Theory + Einstein’s
GR
Only about 4% of our observable universe is made of
real particles that can be directly detected by
absorbers.
The rest 96% is made of virtual particles inside the
quantum vacuum.
Virtual light and other spin 0, spin 1, spin 2 “bosons”
cause repulsive anti-gravity fields that act like dark
energy.
Virtual electron-positron pairs and other spin ½
fermions cause attractive gravity fields that act like
dark matter.
If the explanation is this simple, then attempts to
measure real dark matter particles will fail just like
Michelson and Morley’s attempt to measure the
motion of Earth through the mechanical aether failed
30. Stephen Hawking’s “Mind of
God”
We have also found that our universe is on a run-away-
mode and this accelerated expansion is due to the
presence of dark energy
This has given evidence that we live in a vast cosmic
hologram – the 3-d holographic world is a projection from
a 2-d plane future cosmic horizon/de Sitter future dark
energy cosmological event horizon – this is centre of
cosmic intelligence or the Mind of God towards which we
are approaching – the Teilhard de Chardin’s ‘Omega Point’
/hardware geometrodynamic computer with ~ 10123 qubits
Are we really simulated back-from-the-future 3D images in
the 2D Mind of God on our future dark energy
cosmological horizon? It’s a crazy idea. Is it crazy enough
to be true? We don’t yet know. But many theoretical
physicists are playing with these kinds of bizarre ideas that
the universe is a hologram, a simulation software program.
31. Max Tegmark’s Levels 1 and 2 Classical Reality or
Rocklike Explicate Order
1st level of Reality: David Bohm’s Outer Order or
Explicate Order which obeys deterministic laws of
Classical Physics – Newtonian universe as well
space-time geometries that influence
matter/energy and back reactions of
matter/energy on space-time geometries
(bending/curvature) following Einstein’s general
theory of relativity.. (4 dimensional space-time
geometry – influences matter/energy telling them
how to move and vice versa back reactions of
matter/energy on space-time bending/ curvature
giving rise to real gravity.)
32. Tegmark’s Level 3 Reality: Thought-
Like Patterns of Information
The stability, the hardness, the diversity of matter
is due to this thought-like patterns which exist
beyond space-time but influence the structure of
matter within space-time.
These thought-like patterns the quantum fields
the Schrodinger waves or psi waves are not
consciousness yet.
This is quantum reality dominated by thought like
patterns of information but they are still not
conscious. The thought like patterns of
information (they are still physical fields and they
influence Levels1 & 2) are guiding the behaviour
of Levels 1 & 2 matter and spacetime geometry
33. Quantum theory is not good enough
to explain our consciousness.
“It is argued that immense physical resources -
for nonlocal communication, espionage, and
exponentially-fast computation - are hidden from
us by quantum noise, and that this noise is not
fundamental but merely a property of an
equilibrium state ... It is suggested that 'non-
quantum' or nonequilibrium matter might exist …
Nonequilibrium matter could be used to send
instantaneous signals, to violate the uncertainty
principle, …, to eavesdrop on quantum key
distribution, and to outpace quantum computation
(solving NP-complete problems in polynomial
time).” Antony Valentini
34. Post-Quantum Physics of Consciousness
Consciousness comes from entanglement signal
non-locality in the sense of the excerpt from
Antony Valentini in the last slide.
Einstein struggled for ten years to extend his
1905 special theory of relativity to his general
theory of relativity of the gravitational field He
needed two physical ideas and one mathematical
idea:
Equivalence Principle – weightlessness in free fall
Newton’s action-reaction principle generalized to
all influences of A on B.
The local frame of reference invariant tensor
calculus.
35. Action-Reaction Explains Gravity
Special relativity unified space with time and
energy with mass, but it could not explain gravity.
The reason was that the unified space-time was
rigid. It told matter how to move in the absence of
real forces, but there was no direct back-reaction
of matter on the space-time continuum geometric
field itself.
Einstein’s final gravity field tensor equations
restore the generalized Newtonian principle of no
action without a reaction. The equations show
how unified mass-energy curves spacetime.
36. Action-Reaction and Time
The quantum wave-particle duality is the same as
mind-matter duality. Bohr was already aware of
this.
The particle is approximated as a test particle in
orthodox quantum theory. It is acted upon by the
wave, but does not back-react on the wave - not
so in post-quantum theory.
The wave acts on the particle in the present both
from the past and the future.
The particle back-reacts on the wave in the
present both from the past and the future.
The former is memory. The latter is precognition.
37. Action-Reaction Explains Consciousness
Quantum theory as taught today is in the same position
that special relativity was before Einstein’s 1915
explanation of real gravity as spacetime curvature from the
direct back-reaction of the mass-energy spacetime acts
on.
The entangled quantum information fields pilot the motion
of matter in a much weirder nonlocal-retrocausal way than
does the spacetime continuum, but without direct-back-
reaction of matter on them in orthodox quantum theory that
works only for the less complex lifeless functions of matter.
Quantum information pilot fields are intrinsically mental.
Direct back-reaction of matter on its pilot field excites a
conscious experience in that pilot field. That is the basic
hypothesis that allows naturally conscious AI in androids
and in many other material environments including
perhaps the surfaces of black holes and our future dark
energy cosmological event horizon that literally may be the
world hologram “brain” of Hawking’s “Mind of God.” A crazy
idea - is it crazy enough to be true?
“The aim of this paper is to construct a version of Bohm’s model that also includes the
existence of backwards-in-time influences in addition to the usual forwards causation.
The motivation for this extension is to the need in the existing model for a
preferred reference frame. As is well known, Bohm’s explanation for the nonlocality of
Bell’s theorem necessarily involves instantaneous changes being produced at space-like
separations, in conflict with the “spirit” of special relativity even though these changes
are not directly observable. While this mechanism is quite adequate from a purely
empirical perspective, the overwhelming experimental success of special relativity
(together with the theory’s natural attractiveness), makes one reluctant to abandon it even
at a “hidden” level. There are, of course, trade-offs to be made in formulating an
alternative model and it is ultimately a matter of taste as to which is preferred. However,
constructing an explicit example of a causally symmetric formalism allows the pros and
cons of each version to be compared and highlights the consequences of imposing such
symmetry1. In particular, in addition to providing a natural explanation for Bell
nonlocality, the new model allows us to define and work with a mathematical description
in 3-dimensional space, rather than configuration space, even in the correlated many particle
case”

Early life[edit]
Sedgwick was born in Stockbridge, Massachusetts, the second of five children born to Henry Dwight Sedgwick II (1824–1903) and Henrietta Ellery Sedgwick (1829–1899). On his paternal grandmother's side, he was part of the New England Dwight family.[1] His paternal grandfather was Theodore Sedgwick. He had an older sister, Jane Minot (1859-1918), and three younger brothers, Theodore (1863–1951), Alexander "Aleck" (1867–1929) and Ellery Sedgwick.[2]
Career[edit]
Sedgwick graduated from Harvard University in 1882, and studied law in Boston until 1884 when he was admitted to the bar. He practiced law in New York City from 1885 to 1898. He was elected to the National Institute of Arts and Letters, and was elected in 1893 as a member of the American Academy of Arts and Letters, whose members were chosen from the National Institute; they have since become one entity. He also was a member of the American Academy of Arts and Sciences (Boston) and the Massachusetts Historical Society.
He later became an author and wrote several historical biographies on Isaac Thomas Hecker, Henry of Navarre, Alfred de Musset, and Marcus Aurelius.
Personal life[edit]
Marriages and children[edit]
On November 8, 1895, Sedgwick married Sarah May Minturn, daughter of Robert Bowne Minturn, Jr. (part owner of the Flying Cloud clipper ship) and Susanna (née Shaw) Minturn (Susanna was the sister of Colonel Robert Gould Shaw) at St. George's Protestant Episcopal Church in New York City.[3] The couple had four children: Henry Dwight "Halla" IV (1896–1914), Edith Minturn (1901–1901), Robert Minturn (1899–1976), and Francis Minturn Sedgwick (1904–1967). Their only daughter, Edith, died the day after her birth. Their eldest son Henry IV (known as Halla) died of pneumonia at the age of 17.[4] Sarah May Minturn died of a stroke in 1919.[5]
On May 18, 1953, Sedgwick married Gabriella May Ladd in Newtown Township, Pennsylvania.[6] She was the daughter of Dr. Maynard Ladd and sculptress Anna Coleman Ladd.[7] Ladd, who was 46 years Sedgwick's junior, had never been married nor did she remarry after Sedgwick's death.[8]
Relatives and friends[edit]
Sedgwick's paternal granddaughter was Edith Minturn "Edie" Sedgwick, the daughter of his youngest son Francis and his wife Alice Delano de Forest. Alice was the daughter of Henry deForest. During the 1960s, Edie Sedgwick starred in many of Andy Warhol's short films.
He is also a paternal great-grandfather to actress Kyra Sedgwick, whose father is Henry Dwight Sedgwick V. Henry V is the son of Sedgwick's second oldest son Robert and his first wife Helen Peabody (1890–1948), daughter of Endicott Peabody.
Sedgwick was a friend to Leavitt Hunt, son of Vermont Congressman Jonathan Hunt (Vermont Representative) and, like Sedgwick, also a Harvard Law School-educated New York attorney. Hunt was also a photographer and brother of Boston painter William Morris Hunt and architect Richard Morris Hunt. Sedgwick and Leavitt Hunt frequently corresponded.[2]
Death[edit]
On January 5, 1957, Sedgwick died at Pittsfield General Hospital in Pittsfield, Massachusetts at the age of 95.[9] His funeral was held on January 8 at St. Paul's Episcopal Church in Boston.[10]
Sedgwick and his first wife, Sarah Minturn Sedgwick, are buried in the Sedgwick Pie in Stockbridge Cemetery, Stockbridge, Massachusetts. His second wife, Gabriella, was also buried in the Pie upon her death in 1972.

A new study found that this eerie quantum link can apply even to situations that resemble the larger, everyday world. Scientists entangled two pairs of vibrating particles separated in space, so that when one pair was forced to change its movement, the other pair did as well.
Using electric fields and lasers, the researchers herded the ions into separate pairs and then entangled their motion. Then they separated the pairs by 240 micrometers (millionths of a meter), which is actually quite a span for an atom. Even at this distance, when the researchers changed the motion of one pair — stopped or started the vibrations — the other responded immediately, stopping or starting in kind.
The experiment proved that this kind of everyday springy motion is entangle-able, and blurred the boundary between the quantum world and the regular macroscopic world we live in, where normal objects don't behave like that.
As for why this entanglement, or any entanglement, is possible, physicists aren't so sure.
"It’s a very difficult question," Jost told LiveScience. "I would just have to say that it stems from the laws and rules of quantum mechanics. There are a lot of people trying to understand what it means."
"We've entangled something that has never been entangled before, and it's the kind of physical, oscillating system you see in the classical world, just much smaller," said John Jost, a physics graduate student at the University of Colorado at Boulder, and a guest researcher at the National Institute of Standards and Technology. Jost and team describe their findings in the June 4 issue of the journal Nature.
Previous experiments have entangled the internal properties of particles, such as spin states, but this is the first time scientists have entangled the particles' pattern of motion.
The breakthrough could help researchers build quantum computers, which could theoretically make calculations much faster than existing technology.
"Apart from adding another toy to the quantum mechanic’s playground, this is an important tool for further developments in quantum-state engineering," wrote physicist Rainer Blatt of the Austrian Academy of Sciences in a separate essay in the June 4 issue of Nature. Blatt was not involved in the new study.
To achieve this feat of entanglement, Jost and colleagues set up two pairs of ions (atoms with one electron removed, so that they have a positive charge). Each pair included one beryllium and one magnesium ion, vibrating back and forth toward and away from each other as if they were connected by an invisible spring.

An artistic representation of two entangled mechanical oscillators made up of two pairs of trapped ions. The arrows denote the internal state of two of the ions. The mist between the two mechanical oscillators is used to represent the entanglement.
Scientists entangled two pairs of vibrating particles separated in space, so that when one pair was forced to change its movement, the other pair did as well.
Each pair included one beryllium and one magnesium ion, vibrating back and forth toward and away from each other as if they were connected by an invisible spring.
Using electric fields and lasers, the researchers herded the ions into separate pairs and then entangled their motion. Then they separated the pairs by 240 micrometers (millionths of a meter), which is actually quite a span for an atom. Even at this distance, when the researchers changed the motion of one pair — stopped or started the vibrations — the other responded immediately, stopping or starting in kind.
