I understand pride in construction, but this might be a bit over the top

You also not a metric fan?😇

Doesn’t that mean that the data driven theory calculation was likely underestimating its uncertainties?

What problem gets solved by doing this?

It isn’t actually in any particular need of repair despite what you read on social media.

This is a lovely experiment and all, but didn’t the resolution to this puzzle come from the theory side? 🧪⚛️

Anomaly no more! “Muon g-2” puzzle resolved at last
When theory and experiment disagree, it could mean new physics. This time, they solved the muon g-2 puzzle, and saved the Standard Model.

🚨 Oh wow. Calling the side of the world where it's still dark. Look up!! Look up!! The mega sun burp has arrived 😮

Notes: Get far away from streetlights & look for a silvery shimmer in the sky. Prop your smartphone up on a wall to take a long exposure & reveal the colours. 🤩 🔭🧪

Aurora Forecast Bot from NOAA (UNOFFICIAL) @aurora.nws-bot.us · Jun 1

Aurora Forecast Update for 2025-06-01T07:04:01Z
Additional Details Here.

:Product: 3-Day Forecast
:Issued: 2025 Jun 01 0030 UTC
# Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center
#
A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 4 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Jun 01-Jun 03 2025 is 7.67 (NOAA Scale
G4).

NOAA Kp index breakdown Jun 01-Jun 03 2025

Jun 01 Jun 02 Jun 03
00-03UT 4.00 7.00 (G3) 5.33 (G1)
03-06UT 4.00 7.67 (G4) 5.67 (G2)
06-09UT 4.00 6.67 (G3) 5.00 (G1)
09-12UT 3.67 6.33 (G2) 4.67 (G1)
12-15UT 7.67 (G4) 6.00 (G2) 4.67 (G1)
15-18UT 7.67 (G4) 6.00 (G2) 4.33
18-21UT 7.33 (G3) 5.67 (G2) 4.67 (G1)
21-00UT 7.33 (G3) 5.33 (G1) 4.33

Rationale: By midday on 01 Jun, conditions are expected to increase
rapidly with the arrival of the expected CME from 31 May. G3-G4
(Strong-Severe) conditions are likely, with a chance for G5 (Extreme)
levels on 01-02 Jun. G1-G2 (Minor-Moderate) conditions are expected to
persist on 03 Jun.

B. NOAA Solar Radiation Activity Observation and Forecast

Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was
above S-scale storm level thresholds.

Solar Radiation Storm Forecast for Jun 01-Jun 03 2025

Jun 01 Jun 02 Jun 03
S1 or greater 75% 75% 75%

Rationale: S1 (Minor) or greater solar radiation storms are expected to
persist on 01-03 Jun.

C. NOAA Radio Blackout Activity and Forecast

Radio blackouts reaching the R2 levels were observed over the past 24
hours. The largest was at May 31 2025 0030 UTC.

Radio Blackout Forecast for Jun 01-Jun 03 2025

Jun 01 Jun 02 Jun 03
R1-R2 65% 65% 65%
R3 or greater 25% 25% 25%

Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely, with a
slight chance for R3 (Strong), over 01 Jun - 03 Jun due to the flare
potential from multiple complex regions on the Suns visible disk.

The attack on basic science in the USA is real:

The National Science Foundation just killed half of the Nobel prize winning LIGO experiments (essentially meaning: LIGO can no longer see where a gravitational wave comes from, just that it was there)
