How would they possibly know?
Because observations like this keep coming
'Welease Wosetta!'Rossim said:In the standard model of jets being sublimating gas streams the most dense portion of the jet must be at the surface and dissipate farther out. However, in the following image of 67P I'm seeing more of a sprite pattern in the jet with the densest part a bit away from the surface.
67P from Rosetta: http://www.esa.int/var/esa/storage/...-1-eng-GB/Comet_on_6_February_2015_NavCam.jpg
A sprite for comparison:

This could be a direct falsifying observation since sublimation requires a smooth gradient as the source is expelled. Hopefully some quality data is returned from the 6km fly-by.
As I say in the last line ...
The best is yet to come as 67P becomes more active electrically
Just wait a few months Ziggurat. I wonder what your excuse will be then ?
