Impressed with the results. Here’s hoping we’ll eventually get Sag A*.

What really blows my mind is the fact that it’s got a Schwarzchild radius of 40 billion km, which would put it well beyond many Kuiper Belt objects if it were placed where the Sun is.
This video supposedly shows SagA

I saw that yesterday, looks like they couldn't get the "top" of the black hole that well defined, hopefully with more radio telescopes built in ideal locations (for the Event Horizon Telescope project) around the world, better detectors and refining their data they can get a better picture of SagA.

I wonder if they will be able to obtain detailed Doppler information from the data? It would be pretty cool if they could directly observe frame dragging.

I wonder of they’ll put a radio telescope in orbit or on the moon that may be able to improve the resolution much better than just the diameter of the earth, which is what they did with the current setup.

Here’s an interesting Ted talk about the creator of the algorithm that helped to piece together the data of the picture:

It's a different black hole, but scientists have turned up a pretty effective demonstration of frame dragging:

One again, Einstein FTW.

It's amazing how well his theories are holding up after a century.

Some group is obviously seeking attention and PR, and people are taking the bait.
Looks like somebody was proven wrong.
