Icy snowball comet theory takes another hit - the "impossible" dunes of Comet 67P

The comet 67P has provided an avalanche of astonishing discoveries that may puzzle scientists for years to come. And one problem that will simply not go away is the seemingly impossible dunes, or dune-like ripples at the comet's neck. At its first observation, the feature drew virtual gasps of disbelief from scientists and science media. More recent, close-up images of the "impossible" dunes have only deepened the mystery. How does the electric universe explaining this baffling feature?

Comment: The only thing more astonishing is how desperately mainstream science clings to its original conceptions about comet composition, despite all the evidence coming in from Rosetta and other comet probes. What is behind their apparent refusal to give any credence to the Electric Universe theory, even though it provides simple, elegant explanations for cometary observations?
