I went to Best Buy's website and found a 75" LG TV. The box height is 43.89 inches. A typical household door height is about 80 inches. That's plenty of clearance so I guess I don't understand the question? Are there TVs much bigger than 75"?

Saying that something offers hearing protection is a claim that it has been tested and shown to be effective at protecting the user's ears. Most earbud/headphone makers won't make such a claim because testing is expensive and anyway, that's not what the product is for. It's for listening to media. What is to prevent a user from cranking the music volume up too loud, damaging their hearing, and suing the device manufacturer because they claimed it was hearing "protection"?

Most public libraries by now should participate in interlibrary programs that give them access to just about anything, as long as you're willing to spend a few days waiting. At least in more populous states. You'll definitely need a library card though.

Some research articles are free, and others are behind paywalls. Why? Because it costs money to operate. If you see a research paper you'd like to read that's behind a paywall, any public or university library should be able to get you a copy, because most of them have subscriptions.

Earth has a much more active surface than the moon. Plate tectonics constantly recycles crust by burying it and making new crust, weather erodes crust, etc. Granted, this is a slow process, but it took the moon billions of years to look how it does today, because those processes don't operate there. So there is virtually nothing to erase those craters.

The Guardian article has more information: "Sharon Highsmith said her family connected with a clinical laboratory scientist and amateur genealogist named Lisa Jo Schiele to help them with interpreting the key DNA results and mining publicly available records to locate Melissa."

FWIW, local TV news web articles are a terrible source. If you have any interest at all in the thing being covered, Google a few keywords and find a better article.

Years ago I read somewhere that green lights have a fair amount of blue mixed in to give the colorblind a better chance of distinguishing them. Anyway, full colorblindness, as in only seeing in black and white, is very rare. Most colorblind people can function just fine.
