Baggs
It appears to be the coordinating role this guy had that he's had to give up. He'll still be studying astrophysics and Cambridge is a big enough and well enough respected university to collaborate with astrophysical projects elsewhere. I'm sure it already does.
This might be a bit of a setback for some individuals but I doubt it matters that much in the long term.
With all due respect Baggs, you are displaying a complete lack of understanding about this.
It’s not a co-ordinating role, it’s not like he was sat there with a spreadsheet setting up meetings and taking notes. He was the project lead; which means conceiving of the idea, conceptualising what needs to be done, recognising which research groups around the world are likely to have a relevant input, negotiating with them, applying for funding and seeing the project through. He's not "studying" astrophysics, he's discovering for the first time how bits of the universe work. Not studying.
No matter how big and well respected Cambridge is, it’s the 21st century now and big science projects rely on collaboration. So if you are out of the loop, you don't stand on your own, you fall; and the leading groups around the world leave you out of the big projects. So Kwarteng's dopey little $6bn, should it even manifest, isn't nearly enough. We're out of it now. (Ask me how I know ).
As for it not mattering in the long term, no, I don't suppose it will matter to the people who think the professors at Cambridge are studying astrophysics. It'll matter to the economy, industry, education and employment of scientists though. But the Brexit defenders probably won’t notice. Why would they? Blue passports, eh?
And I'm afraid the Torygraph Science section isn't exactly a barometer of how important things are to science.
