Astronomers Capture First Image of a Black Hole

The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, EHT researchers revealed that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow. The image reveals the black hole at the centre of Messier 87, a massive galaxy in the nearby Virgo galaxy cluster. This black hole resides 55 million light-years from Earth and has a mass 6.5 billion times that of the Sun. Supermassive black holes are relatively tiny astronomical objects — which has made them impossible to directly observe until now. As the size of a black hole’s event horizon is proportional to its mass, the more massive a black hole, the larger the shadow. Thanks to its enormous mass and relative proximity, M87’s black hole was predicted to be one of the largest viewable from Earth — making it a perfect target for the EHT.  The shadow of a black hole is the closest we can come to an image of the black hole itself, a completely dark object from which light cannot escape. The black hole’s boundary — the event horizon from which the EHT takes its name — is around 2.5 times smaller than the shadow it casts and measures just under 40 billion km across.

It doesn't take a long time after they get together for Geralt to realize what kind of power he has over Jaskier.

Jaskier: *is about to do something stupid that will probably get both of them injured or killed*

Geralt: *putting an arm over Jaskier’s waist* / *grabbing Jaskier’s hand and kissing it* / *stretching so his shirt rises, exposing his abs* / *giving Jaskier a suggestive look*

Jaskier: *totally forgets whatever he was about to do, focusing entirely on Geralt*

Ok so the thing about reading like books which are “predictable” is that I, a story enjoyer, go completely bonkers about it bc its like Enrichment in my Enclosure. A scene parallels another earlier scene between different characters thus serving to highlight the differences in their views and priorities???? A line makes me think “hmmm I bet that’s gonna be relevant later” ends up being relevant later????? I am a tiger chewing ice cubes out of a pumpkin. I’m so so happy. Please foreshadow more things. Throw the completely anticipateable plot beats at me like catnip mousies!!!!!

The next time I see one of those “millenials will be photographing the end of the world” posts I’m gonna scream because let me tell you, I just went through a natural disaster and Snapchat literally saved people’s lives. Thanks to snapchat I knew exactly what roads were flooded, what stores were open, what my HOUSE looked like (since I wasn’t there), and which shelters I could go to. People were snapping/tweeting asking to be rescued and THEY WERE. I didn’t get my news from the tv, I saw it in real time on social media and I will never not be grateful for that.

Okay before I share this please realize changes like this is VERY normal this early in production.

That being said it is now:

6x03: The Devil You Know

6x04: Animal Instincts

rather than:

6x03: Animal Instincts

6x04: Evil

'we live with the reminder every day, staring us in the face' was such a cruel line. Coming from a mother about her own son? It makes me sick every time. It deprives little Buck of all humanity, it reduces him to nothing but the constant reminder of a bad memory. It makes him look like some sort of imposter, a stranger that lives in your house and asks to be loved without having any right to. Some horror movie shit. 'Staring us in the face'? Like he's nothing but a body that stole her dead son's features and now keeps teasing her about it; whose only purpose would be to make sure she remembers she has to keep the bad version forever because she wasn't allowed to keep the good one. Demanding attention just so he can torture her with the memory. I do wonder if Buck was ever anything to them - both his parents - other than 'defective spare parts' and a bad, bad memory to look away from for as long as they could
