Astronomers may have spotted a distant alien moon being born (New Scientist). Leah Crane cannot think outside the box. A dust disk is observed around a planet. It must be evolving into an exomoon!
We may be watching the birth of a moon for the first time. Astronomers have spotted a disc of debris around a distant planet called PDS 70 c, and it is massive enough that the young exoplanet might be in the process of forming exomoons.
These expectations flow directly from the myth of progress. Astronomers are not watching a moon form, because the dust disk is a single frame in a movie. How do they know the disk is not disintegrating? Maybe a pre-existing moon is breaking up.
When a new stellar system is forming, the planets coalesce out of a cloud of debris called a circumstellar disc. Then, the planets can suck gas and dust from that cloud to form their own circumplanetary discs, which feed the planets’ growth and provide the material for moons to form.
But if astronomers cannot build planets from dust disks without extreme hurdles, how can they expect dust disks around planets to form moons? Remember the problems with planet formation theories:
- Start Over: The Evolution of Planets Is All Wrong (5 July 2014): Core Accretion Theory faces innumerable problems.
- Planets Defy Bottom-Up Assembly (15 Aug 2015): Building blocks of lie make imaginary planets as well as life.
- Planet Origin Theories Contradict Physics (28 June 2018): Despite major problems, astronomers cling to accretion theory.
- Exoplanets Are Young, Too (22 Dec 2018): Disk instability theory tries to account for a contradiction to core accretion theory.
- Energized Dust Bunnies Make Planets? (12 Dec 2019): Trying to overcome an obstacle in theory, a shocking new idea fails.
- Star Warts: Planets Rebel Against Theory (5 Aug 2020): Rebel armies of anomalies battle against the empire.
Additionally, astronomers have been pushed to believe that planet formation must be rapid to keep from a “death spiral” into the star caused by drag in the dust disk. Observations of gas giants close to stars (i.e., the “hot Jupiters”) have forced them to give up on a slow-and-gradual Darwinian view of progressive formation of planets and moons.
Astronomers are in no position, therefore, to gloss over the
difficulties of getting from a disc of dust bunnies to a moon or a
planet. Theory does not make it so. Believing that an exomoon is forming
from dust because one believes that planets and moons form from dust
illustrates a case of circular reasoning." CEH
