Es la época de oro para la #RelatividadGeneral. Esperamos pacientemente el avance tecnológico para poder contrastar nuestros modelos con datos observacionales. Durante décadas buscamos soluciones exactas, hicimos aproximaciones y por fin #LIGO despertó…
Un colaboración de 80 institutos observó durante 5años el centro de nuestra galaxia y pudo reconstruir la imagen del hueco negro supermasivo de nuestro vecindario galáctico Otra vez la #RelatividadGeneral salió airosa con las simulaciones y observaciones
Desde la Estación Espacial Internacional (ese proyecto colaborativo que ahora Rusia amenaza con abandonar la colaboración por la guerra) un maravilloso instrumento mira estrellas de neutrones por delante y por detrás explorando de qué están compuestas

#Espace - Les bonnes raisons d'y aller
🌿À l'heure de la #COP26, pourquoi dépenser de l'énergie et des finances pour aller dans l'espace. #Thread de quelques éléments de réponses du côté optimiste de la force 🤞

1. Pour trouver notre place dans l'#univers, #explorer, #rêver.
Historiquement, l'observation des étoiles a interrogé, fait rêver. Domaine des dieux, sphère céleste, on étudie le ciel nocturne et l'évolution de soleil en journée qui rythme les vies.

🔭Les #philosophes déblayant les principes de la mécanique céleste posent les bases de l'#astronomie moderne, s'égarant parfois dans des interprétations erronées. Les briques sont posées et ainsi naîtra les #science, #physique, #astrologie, ...

This week FC1 (Filter Cavity [mirror] #1) was installed in the @LIGOWA's new HAM7 vacuum chamber for the new @LIGO A+ Filter Cavity.
FC1 is a triple suspension mirror. This work was also installed in @LIGOWA's NEW "Mega Cleanroom"!
#GravitationalWaves #LIGO @NSF #NSF
Here the HAM7 #vacuum chamber is partially opened up. The FC1 suspension is shyly hiding inside it's protective cover as TJ (Lead Operator), Travis Sadecki (Operations Specialist), & Rahul Kumar (Suspension [SUS] Detector Engineer) prepare for installation.
FC1 Uncovered!
This @LIGO Triple Suspension currently has a "dummy weight" suspended at the bottom, this "dummy" will be replaced with its mirror next! TJ is in this photo.

Thread: This phrase should be sculpted on the #ECB building and both #EU and national parliament. However, it's only partially correct. @jeuasommenulle @nglinsman @dlacalle_IA @bondstrategist @bondstrategist @AlessandroPonz4 @jeuasommenulle @DiMartinoBooth
First, it must be said clearly that while Economist use math, it's a humanistic discipline and not a "science" when taken as a whole, no matter how much you stuff the syllabus with difficult scientific courses.(/)
Anyone involved in the Banking regulation, while quite probably won't admit it under physical torture, would admit that the more "improved" according to "innovation" it got the more difficult it has been to ward off the system from collapsing.(/)

2017 > La naissance de l’astronomie multi-messager via @APC_Laboratory #LaMethSci
S Antier > l'astronomie multimessager n'est pas toute jeune. Il y a eu un vrai essor en 2017 mais en 1987, il y a eu aussi un événement important concernant ce domaine #LaMethSci
MA Bizouard > on sait que les sources qu'on essaie d'observer vont émettre plusieurs messagers #LaMethSci

A collision in #space revealed a #blackhole that physicists thought could never exist. The observatory that detected it cracked a 100-year-old mystery posed by #Einstein.…
Seven billion years ago, two black holes crashed into each other and merged into one enormous #blackhole with the mass of 142 suns.
The collision reverberated through space and time, and these ripples — a phenomenon called gravitational waves first predicted by #AlbertEinstein — traveled 16.5 billion light-years through the universe, reaching #Earth in May 2019.

Ever dreamed about 3D-printing your very own laser lab? Now you can! Print yours today and start exploring core ideas of special relativity, general relativity and quantum physics:
Think piezo speakers are no good? There’s no better way to displace a mirror on a nanometre scale. 😊 Grab your 3D-printed laser lab and start measuring signals like those you’d find in gravitational-wave detectors. #LIGO The 3D-printed laser lab co...
#DidYouKnow lasers are colour-tuned to excite atoms produced at ISOLDE, CERN’s radioactive beam facility. The lasers remove an electron from the atom, turning it into an ion. This is the role of the element-selective ion source called RILIS: The RILIS setup with lots o...

THREAD - How about a bunch of blog posts on #Space and #Astronomy? Yes, I have more than you can imagine - especially since these are really just #physics topics. Hold on - because this is going to be a bit large.
2/ Here is an answer to my fav astronomy question EVER - "What would the phases of the moon look like if the moon was a cube?"…
3/ The great thing about the cube moon question is that it really tests if students understand phases of the moon rather than just recalling factual stuff. Here is my python model of a cube and spherical moon

1. Modest attempt to summarize PhD thesis in 10 tweets. It presented a theoretical, observational & astrophysical perspective on black holes
2. Thesis had 3 parts (10 Ch.): #NumericalRelativity (Einstein on supercomputers), blackhole search in #LIGO & #GravitationalWave universe👇🏻
3. #NumericalRelativity simulation gives us EXACT spacetime physics when 2 black holes collide. It takes 50k hours on fastest supercomputers
