Scientists have studied the moon's surface for decades to help piece together its complex geological and evolutionary history. Evidence from the lunar maria (dark, flat areas on the moon filled with solidified lava) suggested that the moon experienced significant compression in its distant past. Researchers suspected that large, arching ridges on the moon's near side were formed by contractions that occurred billions of years ago—concluding that the moon's maria has remained dormant ever since.

    What an exciting study. The TL;DR:

    GEOlogy is the study of the earth and how it changes over time. At a high level the Earth is sustained by the geodynamo - electromagnetic fluid movement in the core and mantle that sustains mantle convection and plate tectonics. The Moon doesn’t have any of that, so geological processes on the Moon is of intense study. In this paper they found pretty good evidence of contractional tectonics - the surface wrinkling from the Moon shrinking and changes in orbit - effecting all sides of the Moon in the form of scarps which induce moonquakes. This has implications for mapping the surface for future exploratory missions and long-term habitation (don’t want to have a colony in a seismically unstable place).

    My brain is broken. I read it as “geopolitically dead”. Had a chuckle. Had a realization. Now I have made myself sad.

    Sweet, my mother will refuse any science related to it. Unironically her fat ass will support GLP-1s.

            GLP-1 (Glucagon-Like Polypeptide) is a relatively new type drug which promotes insulin release (prompting its use for treating diabetics) and suppresses appetite (prompting use as a weight loss drug). It’s received a lot of attention recently as a result. I believe the purpose of the comment was to highlight that their mother would distrust science unless it actively helps them.

              Thank you I appreciate the in depth response, I hadn’t heard about GLPs and it’s an exciting drug. I think I’m still just not understanding how his mom is the kind of person who understands the nuances of stellar geology and thinks it’s bullshit but also understands the nuances of advancing pharmaceuticals and supports it. So,

              Huh? (even louder)

                Not OP, so can’t be certain, but I think what they were saying was a lot simpler. I don’t think their mother would even attempt to understand stellar geology or pharmaceuticals, and instead has a blanket distrust of science except when it suits herself.

                Geologic activity on the moon doesn’t seem like a particularly objectionable issue (most people would probably regard it with apathy), but then again there are people who think the Earth is flat and vehemently oppose the science which very clearly shows the opposite. I do understand your confusion as the comment likely isn’t relevant to this paper. OP would probably have made this comment or similar on any number of posts about science news and their comment is probably not influenced by the details of the discovery, simply that a discovery was made.
