When did Ganymede get its present shape?
According
to
Darwinists, ”a
massive collision billions of years ago may have dramatically reoriented Ganymede, Jupiter’s largest moon”.
But they have not known
which meteor hit Ganymede, so its just a series of Darwinian tales.
”Naoyuki gata at Kobe University, Japan, and his colleagues
studied Ganymede’s extensive furrow system, a series of concentric troughs
believed to be remnants of the largest impact structure in the outer solarsystem.”
The centre of the
furrow system aligns closely with Ganymede’s tidal axis – the imaginary line
running tales to Jupiter from the centre of the moon’s side that
always faces its planet. This led the researchers to suggest that the impact
that formed the furrows caused a significant redistribution of mass that
reoriented the moon.
Through
simulations, the researchers determined that the impactor responsible probably
had a diameter of about 150 kilometres – significantly larger than the one
that caused the extinction of the dinosaurs on Earth, which is estimated to
have had a diameter of about 10 kilometres.
Andrew Dombard at the University of Illinois Chicago says that
if an asteroid like that hit Earth, “it would be a global sterilising event, a
bad day”.
Upon impact, this
asteroid would have breached Ganymede’s icy crust into the liquid oceans below,
creating a transient crater and hurling vast amounts of material across the
moon’s surface.”
