Eta Carinae
→Possible effects on Earth: removed portion that said a GRB would have to be within a few lightyears to have any significant effects on earth. Common understanding is a GRB could cause a mass extinction from as many as thousands or tens of thousands of lightyears away.

Cotahuasi Canyon
Unreasonable to compare to Grand Canyon, whose depths are equivalent to the depth eroded by the river. Here, there is some depth eroded by the river, but the canyon "rim" elevation is taking from the top of an adjacent mountain peak.

Stellar collision
→Stellar collisions and the Solar System: removed reference to gamma ray bursts. No mainstream models suggest mergers/collisions are a likely source of GRBs. The reference that mentioned this is from 2000, before magnetars and kilonova were identified as short GRB progenitors, and hypernova were identified as longer duration GRBs. Neutron star collisions are dealt with in a separate section and cause short GRBs that wouldn't likely wipe out life on earth unless much, much closer.

Dry cleaning
It said wet only refers to water. Reworded it to exclude this statement. All dictionary entries specifically include other liquids, and the reference cited also says it nowhere. There are likely more accurate ways to explain the name needing to be added here.

Intestinal permeability
→Clinical significance: looked at the sources, and then their sources. They used children who were older than the typical onset age of autism. This means that there is blindspot, in that it assumes that the cause of autism remains with the person their whole life. In contrast, there is no definitive evidence that this is the case. It is important to consider two possibliities--that the cause occurs at onset and may resolve, or it necessarily remains with the person throughout childhood.

Entropic gravity
deleted over-exaggeration that said an object would fall for 36 hr at the equivalent gravity. 12 trillionths x 36 hours implies an object normally takes about 1.5 millionths of a second to fall one meter, which is way, way too fast.

Event Horizon Telescope
→Messier 87*: deleted line about the brighest part being closest to observer. Explanation is inadequate or at least not thorough enough. My understanding is that due to gravitational lensing, the image will always show a ring, from any perspective sufficiently far from the black hole. I could be wrong, but then again, the previous statement was uncited.
