This page contains quick links to animations on this
site. Descriptions and credits are below. Links to animations are in the
box on the left.
(1) 2000/07/15: Correction of
MGS Face image for poor lighting and viewing perspective, by Mark Kelly
Appears in the paper "Proof
that the Cydonia Face on Mars is Artificial". Based in part on
image processing by Boris Starosta <http://www.starosta.com>
and Mark Carlotto <http://www.newfrontiersinscience.com/>.
If you do not already have a viewer for "mov" file
types (needed for the Face animation), you can download the free Apple
2000/07/15: Fission model for planet and moon formation by John Bejko.
Appears in the paper "The
Original Solar System".
(3) 2001/03/20: Improved fission model
animation by John Bejko, 3.1 MB download.
(4) 2003/09/17: A comparative demonstration of aberration and
propagation delay by Matthew Willson <firstname.lastname@example.org>, showing why any force propagating at any finite speed
must operate at an angle to the radial when the source mass and target
body have any relative transverse motion:
[caption for #4]: A source (circle) sends a projectile (arrow) to a target (box).
Source and target have a relative motion. A bright (5-pointed) and a faint
(4-pointed) star are in the background. Above: From the perspective of the
source’s frame, the projectile must lead the target (move toward the bright
star) so that both projectile and target arrive at the same place at the same
time. Below: From the perspective of the target’s frame, the projectile
approaches on a path moving toward the faint star. The difference in the angle
of the path between the two frames is “aberration”.
For #4, "swf" file type is "flash", for which free browser plug-ins are
also available. For example, click
(5) 2004/08/25: H. John Wood acquired an excellent 2-hour video of the 19 November
2002 Leonids storm. The image tube was pointed toward the radiant,
making most of the trails very short. Matthew Willson has extracted a
6-minute portion near the storm peak so that our web site visitors can
get a sense of what this rare spectacle was like. The video is sped up
by approximately a factor of three from real time. However, the field of
view covers only about 10% of the sky. So the video extract shows only
about 1/3 of the real-time meteor rates that an on-site observer might have seen under
ideal viewing conditions.
Caution: The file type
is "wmv" (for Windows Media Video), and the extract file size is 66 MB.
So as a practical matter, broadband internet access is required to
download and view this file. And be sure you have the free Windows Media
Player or some other software that can play videos of that file type, or
can transport the file to a Windows computer.

(6) 2006/03/31 (caption updated 2007/10/01): MPEG animation by Matthew Willson answering the common student
question, "What happens if the Sun suddenly ceases to exist?" The traditional
interpretation of general relativity says that can't happen because, at worst,
the Sun turns to energy, but energy continues to gravitate. But the new physical
interpretation of general relativity has no need to dodge the question. It gives
the answer in the animation, which opens with the Sun's gravitational potential
field represented by a dent in a
rubber sheet, and Earth orbiting the Sun. We also see light from a distant star
being bent by the Sun's potential field as it travels to Earth.
As Earth revolves, we pan down to view under the rubber sheet and see the
Sun itself that caused the dent in the rubber sheet, an analog for the
gravitational potential field. Suddenly, the Sun vanishes with a whoosh. Almost
instantly, Earth ceases to orbit and takes off on the linear path tangent to its
orbit when the Sun vanished, because the speed of propagation of gravitational
force is at least 20 billion times faster than the speed of light. In the meantime, a giant gravitational wave is set
off in the potential field (the rubber sheet) by the Sun's sudden absence. This
wave travels outward at the speed of light. It has no effect on Earth because
gravitational waves have no connection to ordinary gravitational force. But once the wave reaches
Earth's orbit, the light path of the star starts to unbend until the path is no
longer curved and coincides with its straight line path from the star.
So the answer is that all the planets would depart almost instantly in the directions they
happened to be headed. Then one by one, the planets would stop
reflecting sunlight and become invisible as the last rays (from the Sun before
it ceased to exist) reach each planet. The animation separates the
gravitational force effects from gravitational potential field effects.
The former propagate almost instantly, while the latter propagate at the speed
of light. Passing light rays (waves) from other stars are unaffected by
gravitational force, but are bent by refraction in the Sun's "curved"
gravitational potential field.
(7) Updated 2007/10/30: A video of the history of Mars as one of two twin moons of
a gas giant parent planet, and its subsequent alteration by the explosion of its parent
("Planet V") at 65 Mya
and by the explosion of its twin moon ("Body C" or "Bellona") at 3.2 Mya. Video shows graphically what is detailed in the
2007 March 15
Meta Research Bulletin issue. Available in full
screen (18 MB) or small screen (6 MB)
versions. (Both have voiceover and an updated sound track from the original posting.
The video now contains a brief reference to the accompanying K/T boundary mass
extinction event on Earth.)
