Two
important lines of evidence that asteroids originated in an explosion
are the explosion signatures (described later in this article), and the rms
velocity among asteroids, which is as large as the laws of dynamics allow for
stable orbits. In other words, the asteroid belt is certainly the residual of a
larger population of bodies, many of which gravitationally escaped the solar
system or collided with the Sun or planets, leaving behind only the bodies with
the most stable orbits.

Two important lines of
evidence that meteoroids originated in an explosion are these: First, chondrules
(melt droplets) in meteorites are known to have been formed in a sudden heating
impulse, and some have reached temperatures right up to their vaporization
temperature despite the fact that vaporization temperatures vary over the range
1350-1800° C, depending on composition [[1]],
while other asteroids show exposure to a heavy neutron flux, sometimes with
blackening and shock [[2]]. And
secondly, the time meteoroids have been traveling in space exposed to cosmic
rays is relatively short, typically millions of years. Evidence of multiple
exposure-age patterns, as would happen from repeated break-ups, is generally
not seen.
Comets are so
strikingly similar to asteroids that no defining characteristic to distinguish
one from the other has yet been devised. See Figure
1. This is rather opposite to expectations of the solar nebula hypothesis,
because comets should have been formed in the cold outer solar system far from
the relatively warm main asteroid belt. But the exploded planet hypothesis
(eph) tells us that comets are just ordinary asteroids kept far from the Sun
for most of their lifetimes. This means most of their volatiles and orbiting
particles have never been boiled or blown away by solar radiation, so they
still retain considerable gas and dust.[3]
Another factoid is that a trace-back of orbits of “new” comets (that have not
mixed with the planets before) indicates statistically that comets probably
originated at a common place and time, 3.2 Mya. [[4]] But it should be noted that galactic
tidal forces (shearing forces from the gravity of the entire Milky Way Galaxy)
would eliminate any comets that get too far from the Sun, such as comets
originating from any bodies that exploded prior to 10 Mya. So only relatively
recent explosions can produce comets that could still be found anywhere in the
solar system today.
A major explosion would send a
blast wave through the solar system, blackening exposed airless surfaces in its
path. Most such solar system surfaces are indeed blackened, even for icy
satellites. But a few cases have such slow rotation that only a little
over half of the body gets blackened. Saturn’s moon Iapetus is one such case,
because its rotation period is nearly 80 days long – far longer than any other
natural (non-asteroidal) airless moon. Figure 2 shows a Cassini spacecraft
image of Iapetus. One side is icy bright; the other is coal black. The
difference in albedo is a factor of ~10.
The eph is able to predict
secondary properties of this albedo anomaly as well. The dark hemisphere shows
radial streaks along its edges, directed away from the core of the black
region. This shows that the material came from a distant source and had only
grazing impacts near the edges of the dark hemisphere.
Perhaps the most basic
explosion indicator is that, as an explosion occurs, all fragments of
significant mass will trap smaller nearby debris from the explosion into
satellite orbits. So explosions tend to form asteroids and comets with multiple
“nuclei” of all sizes. Collisions, by contrast, normally cannot produce
fragments in orbit because any such orbit must either escape or re-collide with
the surface. Moreover, if satellites are already orbiting a nucleus when a
collision occurs, those satellites will tend to escape into similar solar
orbits, creating an asteroid “family” (many of which are known to exist). The
eph’s 1978 predictions that both asteroid and comet satellites should be
numerous and commonplace [[5]] has been
confirmed in recent years. The first spacecraft finding (by Galileo) was
of moon Dactyl orbiting asteroid Ida in 1993. Other discoveries have led to the
conclusion that several percent of all asteroids have satellites large enough
to be discovered remotely. More recently, Hubble imagery found that Comet
Hale-Bopp has at least one, and possibly three or more, secondary nuclei. [[6]]
Of all the successful
predictions of the eph (and the absence of unsuccessful ones), probably the
most striking was the 1999 prediction of the correct time, place, and rates for
the two peaks of the Leonid meteor storm that November. This prediction success
continued in the following years and included outbursts in other meteor
streams. To date, eph-based predictions have continued to outperform those
based on all variants of mainstream models, especially for meteor rates. Over
100 additional lines of evidence related to the eph and the standard models it
would replace are summarized in [[7]].
