Black hole about to be imaged... oh er missis

Looks like a world network and a bit of computing power is about to capture Sgr A.

Reading this, it seems why all the hard drives are still expensive?

They have tracked the stars around sgr a. Sounds like a hell hole in more ways than one. Hopeful for some interesting info.

[jmorgan]

Think the strapped a load of backyard telescopes together and started to fin d planets. Collaborative seems to be the way to go.

[jmorgan]

Reading with interest. Fascinating stuff. I was aware of the bit about timing but that was probably from some science show.


Working on a roof once and there was a GPS receiver, wonder why the hell you need to know where the building is. Then it twigged, something needed clocking. At least that is what I put it down to.

Black, er

I expect there is a lot of activity as it feeds on stuff.

[jmorgan]

This is the bit I am not sure about. If I look at a black hole, I see the edge? That emanates a lot of energy and can be seen, we hope. However, if I look at the black hole from another point in a 34D universe, I see the edge and a lot of energy escaping. Why is the whole thing not lit up like a christmas tree or will all this be found out?

[jmorgan]

Same link I started with.

I think the artists impression, a ubiquitous one and simple, had me thinking about edges and how we see them from different points. What we see as an edge will be someone else looking on face on. We look on face on and someone else is seeing our face on as an edge.

Roll on April.


Re GPS. Thanks.

Just been watching this presentation by Prof Andy Fabian, he discovered black holes emit incredibly low frequency sound (54 octaves below middle C, with a frequency of 10 million years) which propagates interstellar gas and influences the surrounding galaxy:

On a typical piano your left arm would need to be 9m long to reach the note!

Interesting. They should be able to image something then.

Awaiting South Pole data. October is when they can get it
