The Fundamental Principles of Existence and the Origin of Physical Laws
In this essay the ontological structure of reality is explored. The question
of reducibility of biology to physics is considered in the context of their
ultimate principles. It is shown that biology is an ontologically autonomous
science and is based on its own, independent ultimate principle that is
independent from that of physics. In the next step it is shown that
self-consciousness represents a separate realm with its own, ontologically
autonomous, ultimate principle. Understanding that reality is based on ultimate
principles, a new possibility arises to interpret the origin of physical laws.Comment: 20 page
Metastable and stable equilibrium states of stellar electron-nuclear plasmas
By minimizing free energy density, we show that the stellar core of a
hydrogen burning star is not in a global thermodynamical equilibrium unless
density, temperature, mass and composition assume given values. The core (as
the solar interior) may be viewed more appropriately as a metastable state with
very long lifetime. Slightly non-extensive distribution function could be the
natural distribution for a weakly non-ideal plasma like a stellar core and
represents a more appropriate approximation to this system than a Maxwellian
distribution, without affecting bulk properties of stars.Comment: 14 pages, to appear in Phys. Lett.
The Fundamental Biological Activity of the Universe
If everything is in permanent change, can the Universe itself be fundamentally passive? Answering this question requires a clear concept of ‘activity.’ The nature of ‘action’ is a central and unsolved philosophical problem. Actions play a crucial role in the way we conceive of ourselves, life and the Universe, and the value we put on these. In four decades of research on solar activity, we found that activity is not a mere occurrence but a genuine activity of the Sun, initiated globally by the Sun using quantum processes as tools that generates suitable primary mass flows locally in the solar core that are capable of producing a working dynamo. We argue that solar activity is initiated by biological causes given by the fundamental principle of biology. This universal activity is the basis of our life instinct and of logic too
Multi-timescale Solar Cycles and the Possible Implications
Based on analysis of the annual averaged relative sunspot number (ASN) during
1700 -- 2009, 3 kinds of solar cycles are confirmed: the well-known 11-yr cycle
(Schwabe cycle), 103-yr secular cycle (numbered as G1, G2, G3, and G4,
respectively since 1700); and 51.5-yr Cycle. From similarities, an
extrapolation of forthcoming solar cycles is made, and found that the solar
cycle 24 will be a relative long and weak Schwabe cycle, which may reach to its
apex around 2012-2014 in the vale between G3 and G4. Additionally, most Schwabe
cycles are asymmetric with rapidly rising-phases and slowly decay-phases. The
comparisons between ASN and the annual flare numbers with different GOES
classes (C-class, M-class, X-class, and super-flare, here super-flare is
defined as X10.0) and the annal averaged radio flux at frequency of 2.84
GHz indicate that solar flares have a tendency: the more powerful of the flare,
the later it takes place after the onset of the Schwabe cycle, and most
powerful flares take place in the decay phase of Schwabe cycle. Some
discussions on the origin of solar cycles are presented.Comment: 8 pages, 4 figure
Dynamism in the solar core
Recent results of a mixed shell model heated asymmetrically by transient
increases in nuclear burning indicate the transient generation of small hot
spots inside the Sun somewhere between 0.1 and 0.2 solar radii. These hot
bubbles are followed by a nonlinear differential equation system with finite
amplitude non-homologous perturbations which is solved in a solar model. Our
results show the possibility of a direct connection between the dynamic
phenomena of the solar core and the atmospheric activity. Namely, an initial
heating about DQ_0 ~ 10^{31}-10^{37} ergs can be enough for a bubble to reach
the outer convective zone. Our calculations show that a hot bubble can arrive
into subphotospheric regions with DQ_final ~ 10^{28} - 10^{34} ergs with a high
speed, up to 10 km s-1, approaching the local sound speed. We point out that
the developing sonic boom transforms the shock front into accelerated particle
beam injected upwards into the top of loop carried out by the hot bubble above
its forefront traveling from the solar interior. As a result, a new perspective
arises to explain flare energetics. We show that the particle beams generated
by energetic deep-origin hot bubbles in the subphotospheric layers have masses,
energies, and chemical compositions in the observed range of solar
chromospheric and coronal flares. It is shown how the emergence of a hot bubble
into subphotospheric regions offers a natural mechanism that can generate both
the eruption leading to the flare and the observed coronal magnetic topology
for reconnection. We show a list of long-standing problems of solar physics
that our model explains. We present some predictions for observations, some of
which are planned to be realized in the near future.Comment: 44 pages, 20 figure
The Solar Cycle: A new prediction technique based on logarithmic values
A new prediction technique based on logarithmic values is proposed to predict
the maximum amplitude (Rm) of a solar cycle from the preceding minimum aa
geomagnetic index (aamin). The correlation between lnRm and lnaamin (r = 0.92)
is slightly stronger than that between Rm and aamin (r = 0.90). From this
method, cycle 24 is predicted to have a peak size of Rm (24) = 81.7(1\pm13.2%).
If the suggested error in aa (3 nT) before 1957 is corrected, the correlation
coefficient between Rm and aamin (r = 0.94) will be slightly higher, and the
peak of cycle 24 is predicted much lower, Rm(24) = 52.5\pm13.1. Therefore, the
prediction of Rm based on the relationship between Rm and aamin depends greatly
on the accurate measurement of aa.Comment: 6 pages, 3 figures, Accepted for publication in Astrophysics & Space
