Wecome Erik, welcome wildespace, At least wildespace, you tried to explain it for us.
However in spite of what you say I feel that the Cs are similar and to illustrate this, I have placed them side-by-side. Bearing in mind the different
perspectives and angles, I think they are pretty similar and definitely a 'C'
The two Cs above compared side-by-side, similar size
and now with yours wildespace as a further comparison...
Not really the same eh?
But it certaily illustrates your point how yours is not similar to the others.
Yes, they could be a bubble, but I doubt it. Yours might be a bubble - perhaps. If it were a bubble, that inplies a hollow centre which would not be
filled with rock as this one is, and would leave a definate hollow in the rock,
I do not see how a rock formed by molten magma would capture the 'bubble' as the cooling process takes years and is not instant. If it was as a result
of magma being thrown into water/liquid, then there would be other signs in the rock not just one c/bubble. I think this is a bit of a stretch to come
up with an explanation on your part.
These Cs look as if they have been cut into the rock. Maybe they are a Martian character or symbol?
They do look pretty similar in my opinion, and if we have two, there should be more somewhere but perhaps you could point us to more obvious and
similar examples of molten rock bubbles caught in a freeze-frame both on Earth and on Mars or the Moon. Besides, I thought the Moon was not volcanic,
or are we going with the hair-on-the-copier explanation with that one?
