A wire network that learns, wave-like dark matter, Mars's core & more science news from this week. 

And the telephone rang, nearly everyone happy 😊

You are not wrong, not only is it the news but it makes me happy not depressed

The newsest news

Only news I care about

This lady is the most unlikely youtuber, and it makes my day evertime I see her 😂❤❤😂

both equally important

I keep hearing rumors about Dark Matter being based on Newtonian physics applied at a Relativistic scale (measuring the mass of galaxies/the universe) where some Brazilian paper made it almost entirely disappear by using a Relativistic model.

Invisible things can still interact with matter. How does Dark Matter interact with our Universe?

@@anarchisttechsupport6644 I dunno, that description makes pretty close to zero sense to me. The way to measure mass distribution in a galaxy cluster is to figure out a model that replicates the effect of gravitational lensing through that cluster. That model is based on general relativity (gravitational lenses come from general relativity). I don't see where you'd use Newtonian physics there, nor what you'd want with relativistic effects. Maybe you mean the galaxy rotation thing? But again, it's unclear to me how relativistic effects would help in that context. General relativity is our current theory of gravity, and until you're looking at gravity strong enough to create frame dragging, I don't know of any gravity effects you could reasonably call relativistic. Maybe there's something I don't know, but I thought I understood at least the basics reasonably well. Now if you're talking about theories that try to explain this stuff with "modified gravity", all bets are off, because you're essentially inventing your own formulas at that stage, with - as far as I can tell - the only idea that it has to reproduce the galaxy rotation thing. I haven't heard if anyone managed to explain lensing effects through a cluster that way. Or maybe the idea is modified gravity for galaxies and dark matter for more irregular effects like those lensing effects? Sounds a bit arbitrary to me.

Aa the Architect said about Dark Matter: "Your life is the sum of a remainder of an unbalanced equation inherent to the programming of physics."

@@mitch_the_-itch 'Dark Matter' is supposed to interact gravitationally with the universe but, as deGrasse Tyson pointed out, 'Dark Matter' should be called 'Dark Gravity', since a discrepancy in observed apparent gravitational force from what is predicted by present physics is thus far the only measurable evidence we have for the existence of any such thing as 'Dark Matter'. 'Dark Matter' got proposed as an explanation for that discrepancy. The data never lies but between the data and the interpretation falls the shadow.

Future is so bright, i gotta wear shades!

Hear, hear!

That was brilliant 🤣

@@TheSuszarka Outch!

Aww, came for this, beat me to it. Clever joke indeed.

nah, thats the Elves, obviously

Or the hyperloop. That's why she immediately asked Elon.

She reached 500K a year ago.

@@baileescott401 yeah i think i subscribed in like 2021 or something and idk just didnt notice ig

yes I'm not sure what happened there

@@SabineHossenfelder perhaps a brand new music video for the millionth?

@@SabineHossenfelder I know what happened: you're good, and you kept up your high standards and finally people started to notice

Maybe he was just working on a sponsor contract with Sabine

I have seen this. Excellent!

Do tree roots form a network though? To me it looks more like an upside down tree structure that doesn’t have links between parallel nodes.

The shortest distances between points.

Creating connections between things is simply how things work when you boil everything down.

A brave mind

Also it has an effect on the phosphate retention (as I have learnt from a TED talk). Quite important considering the discussion around 'peak phosphorus'

Its no Theory its Fact. But talking trees? ahh what? 80% of all Plant Life HAS to have Fungal counterpart or else it will die. As most plants cannot Fix Nitrogen. Fungi just naturally form "networks" its what they do. The networks are the Fungus Body essentially. We call these Hyphae. This strand filament looking things that are quite similar looking to a Brain. Now do they respond to pressures and react spreading out Nutrients and other stuff? Yes. Talking? Meh. You get a Cut. Swelling Occurs. Your body singled other areas to bring in stuff to help. That is what is happening. Weird Analogy but this Evolution Strategy, using each Piece or "End" or your body to relay information well to the whole. Instead of relying on the Whole's Features for that information. Is exactly like how Napoleon won so many battles. He created smaller Cores and gave them more leverage to act on information. Which is far more efficient. We also do that to a smaller extent. You foot tells your brain it hurts.

You're keeping me up.
