The Arrow of Time and other mysteries...
Why the arrow of Time points from the past to the future is a mystery that disturb the peace of mind of all scientists trying to understand Time. So also the cause of the low entropy at the beginning. However, the Dynamic Present can deliver a natural and simple explanation on both accounts.

Explaining why time seem to flow from the past to the
future and why the physical laws, in spite of their
symmetric and reversible character, still prefer to unfold
in the same direction is a big problem for the physicists
trying to understand time.
However, the Dynamic Present can offer a simple and quite
natural explanation for this behavior:
As I have explained elsewhere, "Time" only exists in our
mind. It is just the way our brain interpret the never
ending stream of dynamic alterations to the continuously
re-arranging "now" of the Dynamic Present.
It would not be very controversial to suggest that our mind
get a sense of direction due to this, but it does not
explain why the laws of physics would insist on joining the
same flow. That has a different explanation which also will
help us understand why entropy manifest itself the way it
does.
For a glimpse of this mechanism we need to go back to the
Big Bang event.
Whatever it was that made the Big Bang come about, the
immediate result was that the fabric of the universe began
to oscillate in a pulsating mode. These pulses take place in
the form of rapid volume alterations about a mean volume.
Our "now", the present moment, is one full cycle of
oscillation about this mean volume. The next "now" is the
next full cycle of oscillation and so on.
The amplitude of these oscillations would have been large
just after the Big Bang but then have begun to settle. As
they settle, their amplitude goes down, which show up as an
expansion of our universe because the amplitude of the
oscillations is also the standard meter unit in this our
frame of reference.
When the Big Bang event took place it served to "reset" any
previous oscillations that may have existed in the fabric of
the universe. This "reset" is what brings about the initial,
low entropy. As our standard meter then begin to shrink when
the amplitude of the oscillations drop, its smaller size
will enable entropy to find more space where to do its
thing.
However, this still does not explain why the laws of physics
have decided to unfold in the same direction.
The symmetric and reversible character of the physical laws
is due to the likewise symmetric character of the
oscillations, and the reason those laws unfold in the
direction of the flow is because the oscillations are
pulsating volume vise.
They do that because during each oscillation they alter in
volume between large and small size as a result of the
elastic stress induced by the Big Bang into the fabric of
space.
An object will then have more space where to move about
during the half-cycle going from small volume to large
volume then it would during the other half of the
oscillation when less space is available.
It is therefore easier for entropy to rise during the half
cycle when the volume is going from small to large, thus
introducing an "arrow of time" which is actually just
pointing in the direction of least resistance.
Explaining where Time's Arrow and the low entropy came from
is one thing the Dynamic Present can help scientists with,
another is to provide quantum field theory with a natural
time/space lattice for the lattice gauge theories in order
to one day, perhaps, arrive at a "unified" quantum field
theory that would not need to be re-normalized and would be
valid for all particles and forces of the standard model.
Since I know nothing of the mathematics involved, pursuing
this idea must be left to the experts.
Finally, in order to be considered scientific a new theory
or hypothesis must make predictions that can be falsified.
It should also offer some progress regarding the
understanding of the processes on hand.
I suggest the Dynamic Present meet these criteria.
Not only does it explain the chain of relations between most
of the remaining mysteries of our universe, including the
cause of quantum physics, without having to resort to any
"explanations" of the type Jim Baggott refers to as
"Fairytale Physics" in his book "Farewell to Reality".
It also actually makes at least one prediction that could
(in principle) be falsified:
According to the mechanics of the Dynamic Present,
gravitation will be zero at larger distances from the
gravitating body in question where the stretch in the
surrounding fabric of space, which is due to the body's
resonance with the universal Big Bang oscillations, is less
then one Planck length.
That is... less then 16.162^10-36m....
I rest my case for now but will happily respond to eventual comments and questions.
