(…) systematic fractional temperature uncertainty of 0.006, corresponding to 2 K at room temperature (…)
Ok, yes : 0.006 x 298 Kelvin ≈ 2 Kelvin
… i am disappointed that such an expensive and large device producers such a useless uncertainty range.

Galactic spiral arms
we can see animations of stars and spiral arms of galaxies (not what i expected to see)
i still haven’t read “The Three-Body Problem” science fiction novel written by Chinese author Liu Cixin ! (thought i read good reviews about it)
TLDR ; Physicists cannot exactly explain x-ray 10% amplitude oscillations at periods from 400s to 1000 s, observed from the surrounding of a black hole, despite some hypothesis including that a white dwarf would be orbiting it at aprox 50% light speed.
Humanity did not limit its population to a sustainable level. Only a small minority acted differently. Collectively we are still as dumb as 50 years ago. So, we will continue toward the collapse until it’s conclusion.
After the collapse the world will be very different and the population will be way below 1 billion … I bet, maybe, a few million people.
Big hydrogen bombs :
… a study from 1963 suggested that, if detonated 28 miles (45 kilometers) above the surface of the Earth, a 10,000-megaton weapon could set fires over an area 500 miles (800 kilometers) in diameter.
“Can LLMs Think ?” YES “Like Us ?” NO … not right now anyway.
Key point :
“Some planetary systems manage to keep their resonance patterns, and TRAPPIST-1 is one of those systems.”
i like that you were looking for a mechanism to avoid thermal death of the universe.
As for my inspiration : since many years I have read about discrepancies between standard model (including the big Bang) versus observations and I came to believe (with many confirmations as the year goes by) that our current cosmology is incomplete or wrong.
Maybe I don’t follow correctly but what you say would imply that 1 billion years after the big bang (if it was the origin of the universe) there would be no ordinary main sequence Stars left … (?)
that was a nice read for me including historical popularity of different programming language here :

“The team thinks the most likely source is the annihilation of electrons and their antimatter counterparts, positrons.”
… blue shifted and mostly monochromatic.
i wish you have a “biscuit” with that hydrothermal coffee 😋
taken downtown you mean ?
Usually putting together metal and water you get metal-oxide and hydrogen gas.
m + H2O → mO + H2
What they discover is a unusual zone where they have both oxygen (dissolved) and metal. So, i guess they have the reverse process :
mxOy + energy → (x)m + (y/2)O2
They should measure electrical field intensity in the water near the sea floor to evaluate electrical current going through the sea floor from the ocean.
This article was motivating for me by highlighting how much research, learning and cogitation are more important than typing programs.
Oops ! That article citation mixed them up … the comoving is the 33.8 one here … while the light travel distance is the 13.5.
There are three proper distances worth keeping straight in one’s mind: Today’s (comoving) distance, the distance when the light set out, and the distance the light itself traveled.

Hi, do you know you just posted two copies of this in !science (@ lemmy . world ) community ?
