Jupiter's rings may be so puny because of the planet's massive moons

The reference is very interesting and shows at least some of Jupiter's ring system must be very young in age compared to the age of the solar system based upon meteorite dating.

Reference, The Dynamical Viability of an Extended Jupiter Ring System,
https://arxiv.org/abs/2207.06434, 18-July-2022. "Planetary rings are often speculated as being a
relatively common attribute of giant planets, partly based on their prevalence within the Solar System.
However, their formation and sustainability remain a topic of open discussion, and the most massive
planet within our planetary system harbors a very modest ring system."

Paper cited, 12-pages, https://arxiv.org/pdf/2207.06434.pdf, “1. INTRODUCTION A distinctive common
feature of the giant planets within the Solar System is the presence of ring systems orbiting the planet.
Rings systems have been detected and studied extensively for each of Jupiter (Showalter et al. 1987;
Porco et al. 2003), Saturn (Pollack 1975; Porco et al. 2005), Uranus (Elliot et al. 1977; Tyler et al. 1986),
and Neptune (Lane et al. 1989; Showalter 2020)."

My observation. From the 12-page PDF report concerning conclusions, “Furthermore, we have shown
that the outer edge of the present ring system must be relatively young (< 10^7 years) in order to have
survived dynamical scattering processes.” My note. Jupiter’s smaller ring system compared to Saturn
appears young relative to the long age of the solar system (4.56 Gyr), at least some parts of the ring
system.

“5. CONCLUSIONS Planetary rings and moons are very important features of our Solar System, both in
their intrinsic geologic and dynamical properties, and as crucial signposts of planetary formation and
evolution. Understanding the complex interactions between moons and rings, and how these vary with
planetary mass, composition, Hill radius, and time, remains one of the most intricate research topics in
planetary science. The dynamical evolution of giant planet systems is one of the primary ways in which
tracing of rings systems and their ages may be undertaken. The results of our dynamical simulations
demonstrate that the presence of massive moons, especially systems that have migrated into resonance
traps as for the Galilean moons, can create significant dynamical constraints on ring systems comprised
of dense material. This indicates that, although Jupiter may have had intermittent periods of substantial
rings systems, their long-term sustainability may be severely truncated by the presence of the Galilean
moons and associated resonances. Ring material beyond the Roche limit that remain in stable orbits
may also experience eccentricity excitation that enhances moonlet coalescence. Furthermore, we have
shown that the outer edge of the present ring system must be relatively young (< 10^7 years) in order to
have survived dynamical scattering processes.”

I think this raises questions about the ages of all the ring systems found at Jupiter, Saturn, Uranus, and Neptune. Recent catastrophism could be on the way here in the solar system :)
