I love the fact that we can actually *use* gravitational lensing to see things in space even more distant than our telecopes can, almost as far out as the edge of the observable universe. (i.e. before things are too far for light to have reached us yet at all.)
And find surprises, like this early, early galaxy that looks like it had already started rotating 13.3 billion years ago.

Stumbled on this again after seeing it a long time ago:
Photo-realistic renderings of Earth as it might have appeared from space during various prehistoric eras, with different continental arrangements, climate and vegetation (or lack thereof, as in the case of pre-multicellular-life Rodinia).

New round of #introductions for all the new people joining the Fediverse!
Hi, I’m Kelson (he/him), a computer programmer in the Los Angeles area. I talk about all kinds of things here: #scifi/#fantasy, #books, actual #science, #tech, #history, #linguistics, random day-to-day stuff, etc.
I also post photos – mostly cityscapes/landscapes, nature, random interesting stuff I’ve spotted IRL – on Pixelfed (@KelsonV) and more “serious” photos on photog.social (@kelsonv)
Article by Phil Plait explaining the science behind the Event Horizon Telescope’s ground-breaking image of the supermassive black hole in M87 – the world’s first-ever actual image of the event horizon (or, more precisely, silhouette) of a black hole.
Birdsite thread by @AstroKatie on how the image was produced and why the ring looks the way it does, plus simulations of different viewing angles.

I stumbled on a reference to this story recently. Just as fascinating this time as when I first read it.
TL;DR: Apparitions & anxiety in a lab are traced to infrasound from a fan producing a standing wave resonating at the frequency of the human eye. Vic Tandy went on to investigate whether the same waves were present in at least some sites with haunted reputations.
He died in 2005. I couldn’t find much follow-up research in a quick search.

Apparently tomatoes have inactive genes for producing capsaicin, so scientists are trying to use CRISPR to activate the genes & create a spicy tomato, figuring it’ll be easier to grow than peppers.
So I noticed Mastodon’s been trending again & figured I’d take another look. I don’t need another time sink, but I figured it might be worth jumping in this time. Now to replicate just the good parts of that other network…
I should probably figure out what I want to talk about here before I try to figure out who to follow, huh? I mean, I’ll probably end up cross-posting photos & blogging (yes, I still blog), but other than that, do I want to talk about…tech? politics? comics? sci-fi/fantasy? I don’t think anyone I know IRL is here, so it’s a matter of topics for now.
Actually, what *is* the etiquette for cross-posting here?
So, the 5-7 interests meme (this feels like early 2000s LJ): #comics #scifi #space #computers #science #art #photography
Hmm, looks like I may want to check out wandering.shop for scifi/fantasy and photog.social for photography…
OK, so I’ve set up @firstname.lastname@example.org for photography posting. I’ll probably keep this one for other stuff.
The Burger Lab: Revisiting the Myth of the 12-Year-Old McDonald’s Burger That Just Won’t Rot (Testing Results!)
You know the stories about how McDonald’s burgers don’t rot, and therefore must not really be food? Someone did an actual controlled experiment on this to figure out why, and it turns out that it only works with the smallest, thinnest burgers, because they dry out before they start to decay. It’s burger jerky. Try it with a thicker McDonald’s burger, or put it in a plastic bag, and it’ll decay just like “real” food. Homemade burgers behave the same way.
There’s an old children’s joke that goes like this:
“Did you know the word gullible isn’t in the dictionary?”
Then when the other child goes to look it up, you laugh at them for believing you.
On the face of it, it’s a lesson in not believing everything you hear.
But when it comes down to it, the child who goes to look it up isn’t necessarily being gullible; he or she is doing research to confirm their expectations. Yes, gullible should be in there, but let’s make sure. Once you’ve seen a number of dictionaries that all have gullible in them, you can safely ignore the next person who claims that it’s missing, and insist that they put up their evidence.
The child who says, “Really?” and then goes around repeating it? He’s the one who needs a lesson in skepticism.
So the next time someone sends along a bizarre “fact,” especially one intended to spur you to action…dig a little deeper. Sometimes all it takes is two minutes of fact checking to save your credibility. You don’t want to get known as the guy who really did think gullible wasn’t in the dictionary…over and over and over again.
The post Gullible appeared first on K-Squared Ramblings.
I know this is supposed to be fake science, but that last panel makes a disturbing amount of sense.
