Joseph Neal Sr: And thank YOU for your donation. It is most appreciated.

I have found that by insisting people not use obscenities or insults they are forced to think, and thus the quality of the comments on this webpage have improved considerably. In other words, I demand they act like civilized mature adults, and after a short grumpiness most find the rules actually benefit both them and everyone else.

Civilization. What a concept. We should all try it sometime.

Obscenities are similar but are adult bellows that fail to consider the content and counter such with well thought out counterpoint thus the obscenity which is the bellower” reaction “you mean I have to think now and actually write my reasoned counterpoint- bullocks!”

I figured that might be what it was. But it should be labelled that way in the video. (Not your problem, obviously.)
Also, I think that idea makes a materialistic assumption there are no “energy sources” in the Great Deep. The Old Ones are not forever content to be ignored. ;)

GWB: These deep underground observatories are for detecting neutrinos, which can pass through the Earth quite easily. By placing the neutrino detector deep underground you isolate it from other energy sources that could make detection difficult.

Like other commenters here I blame fairies.

Well, in the case of mines, you’d need to blame kobolds. Fairies are lazy and don’t like to get their hands (or wings) dirty. Kobolds do real work. :)

What are they observing 1,000m underground? Usually “observatories” are for looking at the stars. Kamioka Observatory looks like a contractor misread the blueprints and nobody questioned them on the cost overruns for digging a deep hole.

Noticed some inconsistency with negative numbers appearing. Weird.

All of that really cool.

Reminds me I watched a great movie on Amazon Prime called “Thirteen Lives” starring Viggo Mortensen and Colin Farrell and directed by Ron Howard about the 2018 rescue of the boys’ soccer team and their coach from a cave in Thailand.

“But is the O-14 really 49,000 feet deep? The short answer is no, because there is one little catch: directional drilling.”

“In terms of vertical depth, though, BP’s Tiber field in the Gulf of Mexico, drilled by the infamous Deepwater Horizon, became the location for the deepest oil well. The Tiber well’s depth – true vertical depth – was more than 35,000 feet.”

I suspect that abiotic oil is the result, as is “Fossil” fuel-based oil and gas is essentially the same thing.

Massive amounts of biological material being laid down over eons of time and driven down to depth through plate tectonics to where it is very deep and has been there for a long, long time. The earth has been biologically active for the last 3.5 billion years?

I found the video very interesting in how it gave perspective and scale to something that is difficult to visualize.
