Protip galaxies making neon are old. JWST sees an old galaxy making it it's over

Date: November 15th, 2025 6:06 PM Author: swashbuckling meetinghouse It already found a old galaxy making neon in 2022. It's over (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434021) |

Date: November 15th, 2025 6:59 PM Author: gold hyperactive piazza wtf are you splitting hairs for? the first stars were created as part of galaxy formation. the hypothetical population 3 stars were likely already creating neon and exploding before galaxies fully formed because pop 3 stars are thought to be mostly enormous stars that blew up extremely quickly (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434140) |

Date: November 15th, 2025 7:07 PM Author: gold hyperactive piazza you know neon has been around since not long after the big bang. we can even ignore galaxies. Neon has existed since only 10-20 million years after the big bang when the first hypergiants exploded. talk straight instead of fucking around with your word games (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434161) |

Date: November 15th, 2025 7:10 PM Author: swashbuckling meetinghouse Oh now you're going to tell me when the big bang happened. By all means please tell me the age of the universe (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434174) |

Date: November 15th, 2025 7:23 PM Author: appetizing shrine Didn't Weinberg cover that, or was it superseded by the dark matter drama? (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434209) |

Date: November 15th, 2025 7:38 PM Author: swashbuckling meetinghouse Just give me the age already. Someone please (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434244) |
|
Date: November 15th, 2025 7:43 PM Author: appetizing shrine If you're looking for a number, 10^10 years.
What you should be asking is how people arrive at these estimates, then enjoy getting sidetracked by more meaningful stuff like the Weyl curvature hypothesis. |

Date: November 15th, 2025 8:07 PM Author: swashbuckling meetinghouse Maybe I should start more threads about the heliosphere and how it fucked up our measurements of CMBR for 40 years (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434336) |
|
Date: November 15th, 2025 8:12 PM Author: appetizing shrine A big part of physics (and math) is being comfortable with variables. Nobody really cares about the exact age of the universe. Same with an exact half-life of the proton.
What's wrong with today's current estimates, and what difference would further refinement make or mean? |
|
Date: November 15th, 2025 8:15 PM Author: swashbuckling meetinghouse People got PhDs doing this shit in the 70s,80s, and 90s. They measured what they thought was cosmic microwave BACKGROUND radiation. Voyager didn't enter the heliosphere until 2012 after the all the Nobel prizes got awarded, and no one has wanted to call flame on all that research that got done before 2012.
Now they are claiming the heliosphere has a tail, because it it's spherical they're fuct |

Date: November 15th, 2025 8:23 PM Author: appetizing shrine Science advances with new data & measurement techniques.
Nobody threw classical mechanics or E&M out the window because of QM. |
|
Date: November 15th, 2025 8:25 PM Author: swashbuckling meetinghouse All I'm saying is if the galaxies are making neon, they are not baby galaxies. That's a fully grown adult galaxy. Anyone claiming they found baby galaxies better not find neon (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434366) |

|
Date: November 15th, 2025 8:12 PM Author: swashbuckling meetinghouse PS now that Voyager 1 has spent over a decade traversing an enormous wall of plasma that engulfs our solar system, why would you think you can measure faint traces of 14 billion year-old radiation through it?
If you couldn't measure the plasma how could you control for it?
How many Nobel prizes will get cancelled if it turns out people in the 1990s were only measuring the heliosphere? |

Date: November 15th, 2025 8:17 PM Author: appetizing shrine Astronomy is kinda passe, bro. Can you do more HEP poasting? CERN & Fermilab are way more interesting than the George Webb Telescope. (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434355) |
|
Date: November 15th, 2025 8:20 PM Author: swashbuckling meetinghouse What's CERN even doing now? We got (and still seem to get) more interesting studies out of Fermilab. Seems like they are one step away from using CERN to make household cleaning products and ditching the "research" altogether (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434360) |
|
Date: November 15th, 2025 8:27 PM Author: appetizing shrine They're doing lots of stuff that's above my head.
They have some stuff that's relatable to laypeople, like https://home.cern/news/news/physics/first-observation-single-top-quark-production-w-and-z-bosons but most stuff is measurement-related.
They really need to release a follow-up to the CERN rap to get people interested again. |

Date: November 15th, 2025 8:30 PM Author: swashbuckling meetinghouse Yeah somehow someone found money to pay the electric bill to research particle physics again. I think this may the last gasp. Did you see the news reports when "muon wobble" got announced? Total fraud (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434372) |
|
Date: November 15th, 2025 8:36 PM Author: appetizing shrine HEP is the frontier of science. It's a shame most people don't understand the significance.
I imagine Dalton & Maxwell faced similar criticism in their day. |
|
Date: November 15th, 2025 8:42 PM Author: swashbuckling meetinghouse Muon wobble was literally a new dimension. That's what they said .It's funny to think about what the ontological implications would be even if that turned out to be true (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434415) |
|
Date: November 15th, 2025 8:50 PM Author: appetizing shrine What is a dimension, and how many do you think exist? (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434448) |
|
Date: November 15th, 2025 9:03 PM Author: swashbuckling meetinghouse "dimension" is just a fancy way of saying it's a matrix. And it's impossible to estimate how many potentially exist. Availability bias causes us to assign high importance to whatever we can detect right now. Like right now it's gravity waves (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434501) |
|
Date: November 15th, 2025 9:25 PM Author: appetizing shrine Can you think of any reasons why detecting (confirming) gravity waves may be of high import?
Aside: I named my two newest rabbits after Thorne & Wheeler. If you don't have that book, you really should get it. |

Date: November 15th, 2025 9:27 PM Author: swashbuckling meetinghouse It's a neat trick, like building a new kind of go kart or something. "No one ever did this before" (http://www.autoadmit.com/thread.php?thread_id=5798577&forum_id=2:#49434549) |
