The Red Square & Rectangle nebulae, SN1987A, SN2006gy, η Carinae and their
ilk.
How does a reality without
supersymmetry, tachyons and imaginary time look,
feel, taste and sound, please?

The models of GR4 and
quantised SU(10 & 11) are on very much finer
scale, they are capable to explain the image below…
The Red Square nebula
(30.8 seconds of arc per side of image above) may be embedded in a 1 light
year-sized nebula that puts it ~400 light years from here*. Peter Tuthill and James Lloyd** have started to describe the
detailed structure…

The Red Rectangle nebula
has rungs at approximately 300 year intervals for the past 1.4 thousand years.
… and
now we have comparisons between η Carinae and SN 2006gy to make…
Chandra,
APOD 10th May
2007 SN2006gy::

Carinae’s 1843-born, lobes of nickel, weighing-in at 40 Solar masses (~1032
kg) as they looked on
The remaining 100, or so,
solar-mass object located centrally here could convert all its matter to a
single gamma photon (stretching Einstein’s Special theory of 1905 to its
limits). As a result, 1.8 x1048 joules (J) of energy would be
released (Nathan
Smith et al, have 1051
ergs = 1044 joules released at SN2006gy). By
comparison, Sol converts enough material to energy in its fusion reactor core
to source ~1031 J. The Chandrasekhar limit
of electron degeneracy is within the central pixel and is estimated to be a few
solar masses. (Gulp! I’ll have to get a move-on with regard to event-timing…)
Sol outputs 1365 ± 1 Watt
per metre squared of its surface. That surface occupies a colander-like hole in
Earthly space-time. Earth’s distance to Sol is ~ 1.5x1011 metres (about
100 million miles). The reported distance to the Carina nebula by parallax
methods* is 2.7 kpc (7500 ± 500 light years, ~1020
metres).
Double the separation,
quarter the apparent source intensity: increase it by a factor of 109
and the intensity drops by a factor 1018. Hence, 1048/ 1018
~ 1030 and of the order 1/10th Solar output will arrive
here in an instant of time measured in Planck units of proper time.
Without such an impulse, a
‘second moon’ will appear to shine for a few years, or so, from a point source(?!) in the southern hemisphere sky. Latitudes below
60 south will see it 24/7, weather permitting. (Updated
Do any of the current GCM’s include such chaotic variability (e.g. Figure 1) in
their ‘radiative forcings’?
The
luminous intensity of η Car. Is about to follow that seen at SN2006gy (T+350
days since pop).

P.S. How do I calculate if
shelter inside this bean would be sufficient, please?
Conclusion: It probably
won’t.

However,
Brian C. Thomas, Adrian L. Melott,
Brian D. Fields, and Barbara J. Anthony-Twarog
see no threat from η Carinae if there’s no grb.

Joule (SI, J) of energy = 107
(ten million) ergs. On Earth, 1 J is the energy required to move 1 kilogramme
through a distance of 1 metre without friction.
So, when temperatures
approach Planck-scale, T~1032 K :: http://en.wikipedia.org/wiki/Planck_units,
gamma-photon pair-production :: γ -> e- e+ H,
where H is the total recoil energy (Hamiltonian) of this interaction :: leads
to the instantaneous creation of a spherical-lens-like, Ricci tensor driven
shell of visible material*. I mean, it’s like a fairground trick with mirrors:
it looks a lot bigger than it is.
* For an example in darker
material, see HST’s latest view of such a lens ::

a more remote galaxy ::

Pulsar models work with a 1032 kilogramme binary system spinning at
gigahertz, say?
Joseph Ndururi,
20053, Thesis on gravitomagnetism. ‘Masse
current’, dm/dt. This model takes some of the energy
of interaction of 2 (or more) gravitational fields and emits it as a ‘masse
current’ perpendicular to the rotation plane. It is achieved by an addition to
For
η Carinae, this current helps but, by how
much….?
Also, regarding quantum
gravity theory (e.g. Ian Consterdine, 20044), the emissions from
sn2006gy shed more light.
Theory: c à c f(E)
Predicts:
The highest energy
photons, emitted at sn2006gy arrived at Chandra some time after lower energy
photons (created in near-co-located space-time around the burst) arrived at
Spitzer. Comparisons between the light curves of other supernovae and sn2006gy
are more than illuminating.
