Cool. There has to be extra terrestrials, right? What if we are the only ones or what if we are the only advanced ones and the extraterrestrials are like the Neanderthals on their planets…
The Trappist system was added to universe sandbox 2
sheeeit, this fascinates me to no end, man… the possibility and all the questions… if “they” are over there on one or more of the worlds— like how far they have come along in terms of evolution and civilization, what technological feats have they accomplished, how far behind or ahead of human civilization they are… questions about their basic physiology, behavioral patterns, cultural norms, their method of transport and communication, life span, natural abilities, etc. etc. It would be such an incredible scientific discovery if we end up finding actual sophisticated life forms on one or more of these other worlds (or elsewhere)…and send one of those satellite-probes over to observe things more closely.
Of course that might be dangerous if an alien civilization happens to be at or beyond our level of development, and they notice…and misunderstand our little “camera” satellite to be a threat or sign of impending attack…naturally that doesn’t tend to work out so well for the side that’s not as technologically advanced.
*with a permanent night side and permanent day-side planet… that in itself is interesting… I’m assuming the living things of such a world would most likely live in the middle part where things are not too hot or too cold…and over the years the basic rule of life in such a world would be to never go too far in either direction towards day side or night side. If there were human-like beings on that kind of world, you could imagine there would be interesting mythic stories they’d tell as a “cautionary tale” to their children… or monsters and demons to explain away the reason why the people who travel too far into those “no-go zones” of the world end up never coming back.
There’s a novel and movie about that. The inhabitants on another planet are stuck in the dark ages.
I liked the movie. It’s a trip. Warning, it’s slow and kind of disgusting (in that people are unsanitary)
Or – just hear me out – send Ahnold to start the reactor.
Sorry PhD chemist here, that’s bs. On phone rn will expand when I get a chance
EDIT: OK, so it has been theorized many times the use of heavier analogues in biomolecules such as carbohydrates, proteins and DNA. In fact there was a major controversy not so long ago with a female prof publishing an article on Nature where she studied some algae on a lake that had incorporated Arsenic into some of its molecules instead of Phosphorous (crucial on most processes as phosphate is a sorta an energetic currency used in many metabolic reactions). In any case she extrapolated (on purpose many think - sorta like clickbait websites) that finding into something like “life forms based on arsenic (instead of phosphorous)”. There was a major backslash, she eventually retract the paper I think or something and got bashed by many of her peers.
The thing on both cases, using silicon instead of carbon to create dif biomolecules or using arsenic instead of phosphorous on molecules like DNA, is that it is completely unviable as supporting architecture for any organism under regular conditions. Both Si-Si and As-As bonds are labile as fuck, which means that they will dissociate with little effort. Moreover, silicon in particular is super oxophylic (likes oxygen) so any college student taking second year chemistry knows that with a trace of water around that Si-Si bond is gone. Si-C are a little different and are for the most part stable but still as you go down the periodic table on the p-block, the orbital overlap needed for a strong bonding interaction is decreased (because bigger atoms = bigger orbitals = less effective overlap) so carbon chains can be of any length without compromising any stability. There are many examples where nature has a slightly different replacement for a given enzyme/biomolecule but that only happens on conditions that force that. For example, on deep water tunicates, Vanadium is found as an electron shuttle instead of iron (which is the common metal on most higher living organisms). On methanobactin, a bacteria that catalyzes the conversion of methane into methanol (a holy grail in chemistry - like if we manage to get this working is like holy shit Nobel material no doubt), the lack of oxygen makes this process viable, in fact, the active site contains thiones, a motif very uncommon on biological systems (thiones are the sulfur equivalent of ketones, a double bond between oxygen and carbon).
tl;dr I’m not calling the research false, I’m just saying the way yahoo spins it is sensationalist (shocking I know)
To any of you who have taken Topology…well god damn

that someone grew the human trachea using stem cells amazes me.
Yeah, guess they did exist.
Also, we have living dinosaurs. Alligators, crocodiles, turtles, etc.
Birds and sharks, too.
Study: Drinking non-cow’s milk can actually stunt kids’ height
The Study focuses on Cows Milk vs Plant based beverages such as Rice, Almond or Soy Milk.
I am sure if your kids drank Goat, Sheep, Yak or Donkey milk, they should be fine.
Have any of the physicists here studied RiemannianGeometry? (Riemannian manifolds containing tangent spaces imbued with inner products)
Im doing research within this topic leading to complex geometry and I figured anyone who likes physics on the theoretical side would take a look at Riemannian Geometry for relativity.
