Once again, scientists admit everything they had stated as (fact, scientific proof) about an object in the cosmos, was completely wrong.

[exDemMom]

I would say that it doesn’t sound like they had a theory, but instead had some hypotheses about how Mercury formed. They gathered empirical evidence; their hypotheses turned out to be incorrect. Now they must formulate new hypotheses.

This is how science works. The process of having to go back and rethink one’s original hypothesis in no way detracts from the reliability of the scientific method, as some posting in this thread seem to imply.

"Theorists need to go back to the drawing board on Mercury's formation,"

Nonsense. Everything previously known about Mercury is "settled science."

Mercury passes in front of the Sun.

Oh sure. Now they’re going to declassify Mercury as a planet and have to rewrite all the school textbooks

again....

How convenient for the textbook manufacturers.
