Outlines of an observational experiment.

The heliocentric orbital motion of the Earth contains an orbital
component which can be discerned by observations of the unique axial/
equatorial orientation of Uranus in its changes with respect to the
Sun.To isolate the Earth’s orbital component ,where a location turns
through 360 degrees with respect to the Sun in accordance with
Keplerian orbital motion,requires the use of the GPS system and a
satellite which maintains a fixed postion in accordance with the
orbital component.

The current observations of the orbital component are made from a
geostationary axial/equatorial perspective –

The orbital component is offset by 23 1/2 degrees from axial/
equatorial coordinates,the motion of the solar radiation/orbital
shadow boundary seen in that time lapse footage would be altered to a
isolated orbital perspective by having the orbital stationary
satellite follow a trajectory which deviates from a geostationary

The greatest difficulty is seperating axial and orbital motions/
orientations ,humans can only process one motion and orientation at a
time hence the impossibility of explaining variations in daylight/
darkness,the seasons,the unequal noon cycles using variable axial/
equatorial inclination.The inclusion of a new orbital component based
on changing orientation of a location with respect to the Sun over an
annual orbit is required all observed phenomena and replaces variable
axial inclination,it is also a gorgeous motion in itself, a matter of
straightening up the motion of the solar radiation/orbital shadow
boundary by shifting from a axial geostationary to an orbital
stationary perspective  and applying  the lessons learned from Uranus
to be applied to the Earth   –…

Giving geocentrists their due

I enjoyed the nascient attempts by Nicolas of Cusa to move away from
an immobile Earth by arguing from perspectives that would not be
unfamiliar to participants here,the translator’s commentaries are
accurate enough on page 32 to carry the point –

There has always been an element in astronomy where intutive
intelligence is in sync with the step by step approach prefered by the
‘scientific method’,one not favored over the other however developed
intutive intelligence is now rare.Participants may always hear of
Ockham’s razor applied to a scientific approach and  like the ideas of
Nicolas of Cusa ,these things are merely extensions of theological

As a Christian,there is that joyous experience in simple things and
likewise a different enjoyment in complex and intricate matters,a
person can run up and down the scale from simplicity to complexity
without ever having to promote simplicity against complexity and visa
versa.I see people here use geocentric perspectives and that is fine
in one sense but it does not appeal to those who look beyond mere
appearances,likewise the headache of heliocentric or higher structural
reasoning is not the only thing even if the structures and
motions,from the smallest to the largest,make existence possible.

In the absence of anything worthwhile in sci.astro.amateur,technical
or otherwise,perhaps it is good for participants to get a feel for why
there was no real problem with heliocentric reasoning until it became
political in the era of Galileo.

Astronomy books for 4th graders… any recommendations?

Astronomy books for 4th graders… any recommendations?

The young fellow I have in mind is sharp, no telescope,
and likes maps… So I’m planning to give him a copy of
Tirion and Skiff’s "Bright Star Atlas" and a Planisphere
(Lat 42° N) since that is his latitude. And my time now
and then.

What are your recommendations for inspiring reading at
this age?

radio range calculator

I just found this:

I was wondering about the default values there,
especially things like "Receive system noise temperature(antenna+LNA) K"
or "Required overall link carrier to noise ratio C/N dB" are they reasonable?

Stop being a lemming, read the 24 page ApolloMoonHoax.pdf

There’s no denying that Neil Armstrong is hiding from the public and
the media. We are supposed to believe that he is a shy, introverted

A more sensible explanation is that he is ashamed, and doesn’t want to

After Neil Armstrong, Michael Collins, and Buzz Aldrin returned from
the moon in 1969, they held a press conference to tell the world about
their incredible trip to the moon.

These three men just accomplished the most incredible feat the human
race has ever achieved. If you had been in their position, wouldn’t
you have been excited, proud of America, and happy to describe your
trip to the moon?

The facial and body expressions of the astronauts suggest that they
are suffering from extreme emotional stress.

Why would they appear to be so nervous and awkward? NASA wants us to
believe that all of the astronauts are extremely introverted. But
watch the first few minutes of their interview, and ask yourself, are
they really introverted? Or are they suffering stress because they are
lying about going to the moon?

Watch an excerpt from the painfully awkward press conference:

Where Does Light Come From?

Disregarding artificial light sources and light from other natural
sources in planetary systems (lightning, fires, volcanoes, e.g.), are
stars thought to be the ultimate source of all of the /visible/ light
in the Universe?



"Shake off all the fears of servile prejudices under which weak minds
are servilely crouched. Fix reason firmly in her seat, and call to her
tribunal every fact, every opinion. Question with boldness even the
existence of a god because, if there be one, he must more approve of
the homage of reason than that of blindfolded fear."

–Thomas Jefferson to his nephew

Space Telescope Public Lecture Series Webcast – February 5, 2008

           Hubble Space Telescope Public Lecture Series
                            at the
               Space Telescope Science Institute

Speaker:  Kate Brand, Space Telescope Science Institute

Topic:  Galaxies and Quasars over Cosmic Time

Date:  February 5, 2008

Time:  8 PM

Place:  Space Telescope Science Institute (STScI) Auditorium

Price:  Free admission and free parking

Phone:  410-338-4700


Everything we know about the universe outside our solar
system comes  from the analysis of light. While our eyes are
sensitive only to  optical light, telescopes can detect far
fainter light over a  much larger range of wavelengths.  For
nearby galaxies, the combination of optical and infrared
images provides new insight into their  inner workings.
Most, if not all, galaxies contain black holes with  masses
of more than a million times that of the Sun at their
centers.  Compelling evidence argues for the existence of a
massive black hole at the center of our own Milky Way
galaxy.  When matter  falls into these massive black holes,
the systems can shine more  brightly than the entire galaxy,
and are known as quasars. Using multi- wavelength
observations of quasars across much of the Universe’s
history, we can estimate how the super-massive black holes
in today’s  galaxies grew.

Lectures on a diverse selection of cosmic topics are held
the first Tuesday of every month at 8 PM in the STScI
Auditorium, located at 3700 San Martin Drive on the Homewood
campus of Johns Hopkins University. Admission is free and free
parking is available in the lot across the street.

This lecture will be webcast live. The recorded webcast will
also be available for viewing online the following day. To
view the webcast, you may need to download and install
software. See the web site listed below in advance for
