We introduced you to many #Genuinerockstars in 2022 and in 2023 we will bring you many more!
On this last #FossilFriday before Christmas I'd like to give you all something to watch!
The first #GenuineRockstar of the year was @WryCritic, a brilliant palaeontologists and illustrator who introduced us to a new #Pterosaur from #IsleofSkye

#FossilFriday
The second pair of #GenuineRockstars of the year were @azerkle and @chrisjunium who explained the aftermath of the impact that killed the dinosaur by studying sulfur that got into the #Stratosphere

What are gravitational waves?
#Einstein predicted in 1916.
It took almost a century to realize that.
He was "way ahead of his time".
When a gravitational wave passes through objects will elongate and shrink alternatively.

#Gravity #GravitationalWave 1/n

But #GravitationalWaves are tiny so does the elongation and shrinking.

So scientists build an "L" shaped tunnel and sending laser from the middle point to both the edges and back continuously.

The length of the L shaped tunnel is 2.5 miles each side.

#gravity 2/n
The idea is when #gravitationalwaves pass through the L shape tunnel, one side will shrink and the other side will elongate bcoz they are diagonally opposite to each other.

The instrument is so sensitive that it can measure a change in length as small as 1/1000 of a proton. 3/n

#Breaking #Stars #Galaxies #Thread

Today, @RRI_Bangalore (in pic) said in a first-of-its-kind work, using data from an Indian telescope, scientists have determined properties of radio luminous galaxies formed just 200-mn yrs after #BigBang — a period known as #CosmicDawn. 1/n
Pointing out that telescopes, both ground and space-based, are aiming to capture faint signals from the depths of the cosmos to better the understanding of our Universe, RRI said they used the Shaped Antenna measurement of the background RAdio Spectrum-3 (#SARAS3) telescope. 2/n
For the study, SARAS-3, indigenously designed and built at RRI, was deployed over Dandiganahalli Lake and Sharavathi backwaters, located in Karnataka, in early 2020 (see pic). 3/n

EKPYROSIS
2012portal.blogspot.com/2022/03/ekpyro…

Toplet bombs are still the main reason why the Light forces can not intervene directly in the situation on the surface of the planet. Image
The Light forces are now clearing the quantum and subquantum anomaly on the higher mental plane with maximum possible speed and as soon as that is done, they will start clearing the subquantum anomaly on the physical plane, which is the riskiest part of the whole operation.
The most critical timeframe is between now and April 24th.
Accidentally or not so accidentally the cutoff date of April 24th coincides with the end of Kala Sarpa Dosha, a very challenging period in Vedic Jyotish astrology, which ends on April 22:

.@NASAHubble telescope captured a stunning photo of the distant spiral galaxy named 'Eye of the Serpent'

A spiral galaxy nicknamed "Eye of the Serpent" is 35 million light-years from #Earth. The Hubble Space Telescope recently snapped a photo of the #galaxy, which is about half the width of the #MilkyWay and has a supermassive black hole at its center.

@NASA @NASAHubble @esa
Its distinct arms, where stars and gas are compressed, create the illusion of an eye — which is why astronomers call it the "Eye of the Serpent."

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.

businessinsider.in/science/news/a…
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.

@godless_mom Heaven is just a fairy story for those afraid of the LIGHT
#TheoreticalPhysicists prefer to believe in the heavenly fairy tales they can concoct themselves.

@godless_mom Of course #atheists don’t believe in #BigLegoism. That would be stupid.
They believe in #BigBangism which is their mindless substitute for the Designer and Creator of the phenomenally interactive “table” of atomic elements found on Earth — but not in any star.
@godless_mom The #FlatUniverse didn't always fart new #MultiVerses out of its #BlackHoles until #atheist "theoretical physicists" like #NeildeGrasseTyson, who believe in #MythMath, said so.
#FlatEarth #FlatulentEarth
@godless_mom Believe it or not, the micro-moment of the #BigLegoism self-creation of the #LegoUniverse was captured on video.
#Atheists aren’t allowed to believe this because they are only allowed to believe in #BigBangism, which wasn’t captured on #YouTube video.

(1/5) I'm excited about a new paper that I've written with @GordanKrnjaic and Sam McDermott. It combines some of my favorite things: black holes, dark matter, and the Hubble tension.
arxiv.org/abs/1905.01301
#blackholes #cosmology #darkmatter #Hubble
(2/5) If even a small number of black holes were created around the time of inflation, their relative abundance would grow as the universe expands, making it quite plausible that the energy density of the early universe was once dominated by black holes.
(3/5) If these black holes were small, they would quickly Hawking evaporate. Unlike most other particle production mechanisms, this generates all kinds of particles, no matter how feebly interacting -- a promising way to generate dark matter and dark radiation.

The Event Horizon Telescope will be announcing its results at 6.30 pm IST on 10th April. The @ehtelescope is trying to image the shadow of the supermassive black hole at the centre for our Milky Way, so this is going to be big news indeed! This is a thread on the #EHTBlackHole
You can watch the press conference live at nsf.gov/news/special_r… and
. Press note on #EHTBlackHole at nsf.gov/news/news_summ… & eso.org/public/announc…. Why are we all excited about this? What will the @ehtelescope announce? How can we image a black hole?
Will they show us a blurry image of #EHTBlackHole where we can't make out anything, like xkcd.com/2133/, or something that will make us gasp in awe, like bbc.com/news/science-e…? Follow this thread to figure out the why, how and what ...
