no, common hallucinogenic tropes are just remnants of our evolved collective unconscious; not any proto-communications from other dimensions. i am plenty familiar with them and other characters, and their lessons always seemed terrestrial, subconsciously familiar.

"No", eh? Well I've talked to them a bit too and I think there's somebody there.

What did they say?

There's zero consensus, but there's enough evidence that congress decided to include some interesting legislation in the latest NDAA https://douglasjohnson.ghost.io/uap-related-provisions-of-th...

The "interesting legislation" is more likely to find Cold War-style fuckery of the sort that led to the "red mercury" hoax and other intentional misdirection, and the amplification of conspiracy theories by adversaries than it is to find aliens.

You should at least read the link and the history of how the legislation came to be before judging.

Question for people up to date with modern biochemistry: if there were extraterrestrial microbes on Earth right now, with totally unique chemical origins unrelated to proteins, nucleic acids, saccharides, etc., how likely would we be to notice them? And which analytic method would find them first? Is there a systemic search for this kind of crazy stuff, and where are the review papers for them? I don't know the keywo…

Very, very unlikely like astronomically so. Most microorganisms are so small they're practically transparent so we have to exploit biochemistry to "stain" them - hence why you'll often hear of bacteria classified as either Gram positive or negative, because of the Gram stain. If the biochemistry is unique or even slightly different i.e. right handed chirality, we'd basically have zero of our usual tools at our dispos…

> There's already a whole world of terrestrial microbes that we expect or even know for certain to exist but can't culture, let alone stain, which means we can't really study them.

That sounds pretty cool for a hobbyist to potentially spend time on. Anything you could recommend to look at, for following up on this unknown stuff?

> (when they really, really love one another) can mix and meld to form a new organism that can replicate itself in turn I know it's a bit tongue-in-cheek but I kinda wish they'd go with something more realistic that also explains our perspective, something like "when two organisms feel compelled to have sex". Even in humans it's a big stretch to say that deep love is a prerequisite and I think adds some harmful perso…

It’s a reference to some old fashioned language used in older sex education materials.

We didn't even know about Megaviruses[0] until 2010. [0] https://en.wikipedia.org/wiki/Megavirus

Or Pandoraviruses[1] in 2013.

Also TIL giant viruses have their own Stargates[2].

"V'Ger": https://youtu.be/kHUZCVl28lg

V’Ger wasn’t built by humanity it was built around a fictional Voyager spacecraft, who built it was never disclosed by the common fandom theory is that this might have been the progenitor idea to what eventually became the Borg in TNG.

Hmm, Memory Alpha does confirm your facts. I never realized that the remainder of V'Ger had been "constructed" by someone else. I had just assumed that it had ... spontaneously grown and developed out of the Voyager VI core built by humans.

Where did this backstory come from? Certainly it was not treated in the original theatrical cut, where Kirk only finds its true nature toward the very end. I certainly don't remember anyone being able to trace the history of V'Ger with any certainty beyond finding its original inscriptions.

I've always found the framework we use to search for extraterrestrial life to be too based on our own experience. It could take countless forms, most of which we could never recognize or understand, and might be present everywhere without us knowing. I'm glad that more of the science community is pushing to broaden our horizons.

Counterpoint: Alien life will probably look very similar to life on earth. If you look at evolution then countless species have evolved into something crab-like: https://www.youtube.com/watch?v=wvfR3XLXPvw Turns out that their form is pretty good for survival. While biology can take on a myriad of forms, the competitive nature of life will weed out a lot of them. And since the rules for biochemistry are the same acro…

> Turns out that their form is pretty good for survival

Their form is pretty good for survival on Earth, we don't know if they're good forms for survival elsewhere or in general.

Funny how both UFO and Angel/Devil sightings went down just as ubiquitous personal video recording devices became commonplace...

Been too long since we've had a nice grainy photo of bigfoot.

Just yesterday I was wondering why — with the ubiquity of surveillance, phones, and body cams — we haven’t yet seen footage of good cops intervening to stop people like Tyre Nichols from being beaten to death.
