Alright, so, black holes right?

Most people have probably seen this astOUNDING image of the black hole at the center of the M87 galaxy - the first real picture of a black hole.

It may look like a blurry orange donut, but you gotta understand, this was and still is a hugely impressive achievement. At a black hole's event horizon, the escape velocity (or the speed at which something has to travel to escape the body's gravitational pull) is faster than the speed of light. By definition a black hole cannot be directly observed. Imaging the shadow of M87* required using eight ground-based radio telescopes all over the world, working together as an interferometer - or as though they were one single telescope the size of the entire planet.

So that's fucking cool in its own right, but how did we know that black holes existed before 2019 when we could actually "see" one? How do we detect something that reflects no light when we DON'T have a simulated telescope the size of Earth? The answer is gravity.

We think that most large galaxies have supermassive black holes at their centers, left over from their chaotic infancies when hundreds of thousands of early stars collided and then collapsed, and then kept colliding. To give you an idea of what we mean by "supermassive", the black hole at the center of the Milky Way, Sagittarius A* (pronounced "A-star"), is about 4 million times the mass of our sun. And that's SMALL.

So while black holes aren't the horrible all-consuming reality-guzzling unmakers of creation that science fiction likes to paint them as - we aren't in any danger whatsoever from Sagittarius A*, now or ever - they CAN get big enough to really throw things around. So we looked for objects moving under the influence of . . . nothing.

This gif is a years-long timelapse of stars orbiting something in a seemingly-empty region of space the center of the Milky Way, the approximate location marked with a red plus sign.

That something is Sag A*. It's an invisible behemoth, made of the extraordinarily dense remains of the birth of our galaxy, juggling entire solar systems the way Jupiter flings asteroids. And for so long, we couldn't even see it.

This shit makes me go fucking crazy. Imagine what else is out there that we don't understand just because we don't have the tools to even know it exists! Not just in space, in any field of scientific study!

It wasn't until the 1990s that we started realizing trees talk to each other, and now we know there's fungal mycelium networks that connect trees across entire continents. Just THIS YEAR we discovered an entirely new ecosystem underneath the hydrothermal vents in the deepest parts of the ocean floor. For most of human history, the existence of planets around other stars was highly debated, and now we've confirmed over 5 thousand of them. We even know what some of their atmospheres are made of!

There's a saying that "the more you know, the more you know you'll never know", and I feel like there's never been a time in history when that's been more true. And it's almost comforting, y'know? The universe is so vast, it feels correct that we shouldn't be able to understand all of its intricacies.

Reality is stranger than fiction, and the reality is there's stuff out there that we don't even have the words to begin to describe. Until we do! And our reward is even more questions!

Kenshi Yonezu and his music is as close as we can get to the handwriting of God.

I mean look at this guy-

I love all of his songs, there isn't a single one that I hate or dislike. I could talk about this man all day.

And for those wondering why I'm suddenly sharing this thought at 3:46am, it's because I'm listening to this song on repeat at the moment:

"M87" by Kenshi Yonezu✨✨

Okay that's all.✨

#Kenshi Yonezu #m87 #jpop ベスト #He is the musician you need and the musician we all deserve✨✨ #I can give over 20 facts about this man✨ #His new song “Tsuki wo Miteita- Moon gazing” will be coming out soon as the official theme song for the latest part the F.F. Video game✨ #he's really cool #Like *slams fist on table multiple times* ✨so cool✨ #Youtube

El seguimiento de la radiogalaxia M87 confirma el giro de un agujero negro

La cercana radiogalaxia M87, situada a 55 millones de años luz de la Tierra y que alberga un agujero negro 6.500 millones de veces más masivo que el Sol, exhibe un chorro oscilante que oscila hacia arriba y hacia abajo con una amplitud de unos 10 grados, lo que confirma la existencia del agujero negro. girar. El estudio, dirigido por el investigador chino Dr. Cui Yuzhu y publicado en Nature el…

Sharper Look at M87 Black Hole

The iconic image of the supermassive black hole at the center of M87—sometimes referred to as the “fuzzy, orange donut”—has gotten its first official makeover with the help of machine learning. The new image further exposes a central region that is larger and darker, surrounded by the bright accreting gas shaped like a “skinny donut.” The team used the data obtained by the Event Horizon Telescope (EHT) collaboration in 2017 and achieved, for the first time, the full resolution of the array.

M87 // Rolf Olsen

M87, also called Virgo A, is an extremely radio-loud galaxy, meaning it emits a lot of light in the radio. The source of this radio? Likely a supermassive black hole at its core!

This black hole, called M87* (M87-star), is about 6 billion times the mass of the Sun and has a size of about 120 AU, or about 3 times the distance between the Sun and Pluto!

M87* was the first black hole to ever be directly imaged, a task accomplished with the Event Horizon Telescope (EHT) in 2019. This telescope works by combining the light-gathering power from several radio telescope across the world, effectively making a telescope as large as the Earth itself!

The black hole is currently swallowing up material and has a ring of highly ionized gas around it (shown in orange in the inset). Sometimes the black hole "burps" and emits a jet of matter. This jet currently measures about 5,000 light years long moving at about 85% the speed of light.

O4.I2.2O2E

In che modo dimostro il mio amore?

Partendo dal fatto che ho capito che sono incline all' accudimento, prima questo tratto era uno dei principali motivi delle mie relazioni, tossiche.

Non tutte ovviamente.

Banalmente, volevo curare tutti perché nessuno ha mai curato me.

E voglio ancora farlo, sia chiaro.

Semplicemente adesso riesco a mettere dei limiti al male che gli altri possono farmi mentre io li curo. Non sempre, ma ci provo almeno.

E quindi il mio modo di amare qual è?

Credo sia rendere felice il tuo bimbo interiore, quello che da piccolo magari non ha avuto tutto, o che comunque, anche se ha avuto tutto, hai lasciato un po' indietro adesso.

Ecco, non voglio che lo lasci indietro.

Ed ora lasciando andare un po' il flusso, è un caos. Un caos perché sto abbastanza okay.

Pensieri non troppo positivi ma neanche troppo tristi ed opprimenti come qualche tempo fa.

È sempre un "và e vieni" sia chiaro.

Una montagna russa di merda e tristezza e vuoto e angoscia ed implosioni.

M87.

Ora però è un po' meglio, non vedo una via di uscita ancora valida, ma cerco di costruirla.

Continuando il flusso, mi fai un effetto che mi piace, ma che non dovrebbe esserci.

Continuando il flusso, domani vado a Roma, un'altra bella carbonara mi aspetta.

Passo più tempo li che in casa.

Davvero dico.

Se calcoliamo le ore da sveglio che passo in casa è così.

Ho sonno, vorrei dormire un po' decentemente, con qualcuno che si incastra tra i miei spazi.

E magari sognarla per poi ritrovarmela accanto.
