The beginning of a new chapter in how we understand the universe and the fundamental laws of physics.
Scientists are set to unveil the first ever direct image of a black hole later today.

This day, years in the making, is the product of the Event Horizon Telescope (EHT), which is a collaboration of several observatories around the world to form a radio telescope array as wide as Earth itself

What will the flat-earthers make of it?


A useful primer to help understand the image that we'll likely be seeing;

Interested to see.

im wondering what they will regard as a pic of a "black hole". Technically speaking, if you view a galaxy from the top, you are looking at a black hole, seeing all it is going to devour.

Don't photograph the damned thing!!! We will all get sucked into it via the camera!!

I CBF watching the whole thing. Can somebody summarize how one one gets a photo of something that sucks everything in - and therefore no radiation / light etc can be travelling toward the camera- no "photograph" is possible.

Ok , super simple answer.
You can't see the hole itself , all you see is a ring around it . The ring is light that swings around the hole that hasn't been sucked into it in our line of sight.
I finally seen the image , it's not that exciting . But it is how they thought it would look like , kinda .
So kiddies , that's why you should listen in maths class , so one day you can do this crazy sh,t !

Mark, we're not seeing the light that has passed the event horizon so you are correct.

What we are seeing is everything going on outside the event horizon - all the matter and radiation flying around before it gets sucked in.

If you want to know more about what an event horizon is, you need to do your own research as it's far to complex to explain here.

Hope that helps.

Yep and the first images of planets where fuzzy dots too...so be prepared for sharp images in the near future. Remember though, unlike planets in our solar system, in order to photograph the black hole we have to peer through the dense core of a galaxy with billions of stars and nebulae far away.

Question, should you focus about a hole or your life?

When I'm not sailing there seems to be a hole in my life.

Explaining how they get an "image". She spends a lot of time explaining the caution required to not have your filter being so tight that it gives you what you're expecting from noise. But it's a pretty tight filter.
