But that wasn't the only problem. Vast, swirling¹ clouds of dust and gas prevent visible light from the centre of our galaxy² from reaching us, making what lies beyond hidden from view. 

 

It's like putting a blanket over the thing you are trying to look at. It's putting a thick fog around that. So there is only certain wavelengths³ of light that can penetrate⁴ through that. 

 

Without the means to see through that dust, the black hole that theory suggests it should reside at the centre of our Milky⁵ Way would remain nothing more than a bold but unproven idea. 

 

With the quest to find the black hole seemingly blocked, there was nevertheless one glimmer⁶ of hope. Now at least astronomers⁷ had some sort of notion where one should be hiding. To tackle the problem, what would be needed was a new generation of telescopes and that would take a new generation of astronomers. 

 

We were just at the point where we had the technology to address that question. And so in some sense it was I had the right hammer and I was looking for the right nail.
