Those grooves remind me of something I saw underwater in the Cayman islands.
The grooves were formed by rocks being pushed back and forth by the waves.
I wonder if there is enough gravity from Mars to move rocks on the moons surface.

Re: APOD capture application for Linux backgrounds?
Does anyone know if a script has been written to set the background for Linux desktops? In particular I am interested in KDE/SuSE. This may not be exactly what you are used to. I cycle my background every hour and a lot of the images I use are from APOD. This script does not come with a GUI or drag...

I'm trying to hold back from posting links. Bad habit Links a bad habit? Links are fine with me. I even read a few that you posted. I just finished probing Google with the key words 'black hold fluid' and I see that my memory has failed me again. Some scientists believe that the material of a black...

Hello DanEspen Hi. A Black Hole is an ultra dense plasma matter object. As I said, I'm not a physicist. I used the term 'rigid'. Plasma sort implies something like a gas, but the 'stuff' in a black hole is under enormous pressure. Surely whatever form that matter takes, it's locked together in the ...

NGC 4696: Energy from a Black Hole
I've seen this news item, but I'm not sure I understand this efficiency. Are they trying to say that there is just as much matter/energy coming out as is falling in? If so, that seems to contradict the idea that nothing can escape a black hole. (Yes, I'm not a physicist.) I've read about black hole ...
