Great to see Andrea Getz on here as she was part of the team that proved Sag A star was a supermassive black hole.

Does the black hole spin. if it does how would it spin

watching this, I have a few questions : 1_Does the star give away some of its light to the black hole when it comes to nearest point?, 2_How could they measure the space curve of the star getting close to the black hole as shown in the animation?

That black hole is camera shy, we just need to be a bit more patient :p

yey updates :) Personally id love the black holes to be doughnut formed.

Observing the behaviour of massive objects that close in towards a very small point in space, reveals black holes and their pulling power.The bright ring you see, is light slowly spinning towards the dark dense, abyss. Thus leading light to it's eventual demise, and making the mass ever more dense....Scary stuff.

5:53 are you kidding me? Actually light never crosses event horizon, as we know the light's behaviour it finds an easy way to travel, means light turns it's way when dense or less dense environment comes(diamond, water). So what happens in here is when the light reaches near the event horizon it turns it way to the side and goes with the edge, never goes inside the black hole. This is the reason of gravity lensing.

Great sir you are my favourite one.👍🏻🇵🇰

Thank you scientists 😘😘😘😘

These are theoretical models and there are more than one of them. Each has it's own uniqiue properties and possible elements for what the event horizon MAY look like. The models exist so when we do have an image of the EH, we'll be able to compare what we've observed with one of the models which will then give us insight into what physics are actually at play.

They did it!!

See the video by Veritasium which explains that. Basically light orbits around the BH pretty much like a satellite orbits around the Earth. So at the right distance, it simply goes around it and then comes back to us, so the bh is surrounded by a very weird halo of light.

Is there any kind of electromagnetic attraction at all (from a super-massive black hole)?

@lancetschirhart7676

Black holes do technically have a charge, but no - nothing that would have an effect on a macroscopic scale. It's all gravity, bent spacetime.

well, it seems fairly obvious that by now that these two separate teams have discovered evidence for new physics beyond GR. Very exciting decade ahead in astrophysics.

this a re-up? i rememeber the beginning of this from another WSF video. edir: ok this is definitely a re-up but im assuming its a re-up because the date from the event horizon telescope is almost figured out? buddy said the first part of 2019 it could be ready and we are in the first part of 2019 lol

The press conference the image is apparently going to be released at is at 9am EST today. Figured I'd throw that out there in case someone wanted to watch it live.

I think you're about 25,000 years too late

But time cannot be seen. What time have to do with a black hole? I understand time when it comes to distance in space

How do you observe a black hole? With a good heaping of skepticism. Several immediate thoughts come new image (4/10/19)to mind: 1. Shouldn't a black hole produce an accretion disk? 2, If that IS a blurred accretion disk, shouldn't the emission be strongest on the inside edge of the accretion disk? 3. Shouldn't a black hole accretion disk be homogeneous? Some pretty large lumps there. What I'm seeing is a plasma torus. not an accretion disk. And if it is a plasma torus, surrounding a black hole, shouldn't the torus be brighter and hotter on the inside edge that faces the black hole? It is not.

You observe it by watching me

Mr Shep said, that the distance to that specific black hole they are studying is approx 25000 LY, and they send radio signal to that BH etc… does that mean that the radio waves needs 25000 LY to reach that BH and same amount of time to get back… is that realistic ?!!

@DavodAta

@@rwbmal I understand that LY is unit of distance, if you send radio waves/signals to a target (black hole) that located at "25000 LY" from you it will take 25000 years until your signal arrives there (we assume that the radio signals travels at light speed) and same amount of time to get back. My life time is not enough to see the result :-)

Nice pic deer

The only issue I had with his whole speech is that the interviewer seemed to almost insult Einstein for his disbelief in black holes. Black holes are a very difficult thing to grasp. He acted as if Einstein not believing in them made everything else he did small. He says, yea he was smart but he didn't believe black holes existed, did he? Maybe not, but when is the last time you changed the entire scientific communities understanding of life as we know it sir?

I guess it's a cogent way to put that we're gonna watch another Nolan movie in a few years!!

The 'black hole picture' is an artistic rendering of compiled data. They used only data that conformed to their biases. They do the same with all dating methods - if a physical thing is expected to be millions of years old and it dates to only thousands of years old, they discard the results and say it can't be dated.

What I have questions about is the difference between Mass and Matter? Also where does gravity fit in to that?

OK, I was wrong.

I have an idea why universe expands for accelerating rate. So first, There is no boundary between universe and emptiness. Universe is mountain of matter on empty space, black energy is kinetic energy from big bang and that energy which is accelerating it, is simply energy of vacuum. When you have a vacuum, and you break the walls around it, matter rushes onto it fast. That's the black energy type 2. Type 1 is the kinetic energy from the big bang. Those 2 together make up the calculated amount of black energy in the universe. Emptiness around Universe is perfect vacuum, Universe is not, there is around 2-3 atoms on every 1 square km. Matter rushes onto the more empty space what is emptiness around Universe. You can imagine like when you have full bucket of water and you are standing on a flat surface. You pour that water onto the floor fast, it rushes in every direction from the center point where you poured it. That same thing is happening with the Universe. Big bang was that pour of water.

@3:57 The star would also go dark if it no longer produced the spectrum of visible light. What if the power it generated from in it's core to just outside its surface was so massive that the black hole produces a spectrum of light we are not able to see with the unaided eye? The energy it produced would be so intense, like the energy the microwave produces is beyond visible light, we wouldn't be able to see. Even an X-ray machine produces a wavelength of light we cannot see. Same thing goes for radio, it is a spectrum of light that we cannot see. The reason why the star is black then would not have anything to do with gravity or mass but because of the spectrum of light it produced was beyond what we are able to see.
