No, it's a Kodiak on 'roids.

It is unlikely to the point where it can be considered a non-zero chance happening. In other words, it's more likely for it to have been found by a Neanderthal with the holes already in it than to have had the holes accidentally placed correctly to function as an instrument.

It does not track. Your example is excellent; dolphins have bigger brains than humans but they use most of that for echolocation. Neanderthals had smaller frontal lobes and larger occipital portions.

Actual beaver tails are quite tasty.

Thanks to carcinization, you might yet.

Project Hope Hubris?

Edit - I'm so happy a few people understood this reference.

The subs and carriers have nuclear power plants aboard to generate electricity. While that power is used for propulsion, it's not the same thing as a nuclear engine. A nuclear rocket engine operates on the same principles but rather than using the heated water to turn a turbine, the water is directed through a nozzle to create thrust.

Nuclear powered and nuclear propulsion are two very different things.

That's what asteroid mining is for.

Waterbeds too.

The overall percentage was roughly 40 in 2019. It's likely increased since then. Reddit specifically? Probably about that same 40%. Have a look at the usernames and you may see a pattern to a large number of them. Those are the likely bots.

Have a look at the usernames on reddit or twitter and it becomes fairly obvious which ones are bots. They all have a particular style to the names.

Redditor for 11 days. Totally legit account. /s

The red dwarf companion is Proxima, IIRC. Alpha Centauri A and B are yellow and orange stars, right?

Hooray for mustard!

I flew over the crater in the pic 3 days ago. It was awesome.

That's why a Niven Ring is a better idea, unless you're talking about the original concept of a Dyson sphere.
