Professor Hawking is a world class Physicist, a master in his field but he can only debate on how he perceives the EU to impact his field.
Quite why funding for science would dry up if we left the EU or indeed the traffic of the highly qualified would cease on Brexit is beyond me, would there really be a new Iron Curtain between here and mainland Europe?
How on earth did the Industrial Revolution and the largest empire the world has ever seen occur without or before the EU?
Let me qualify abusive relationship if I may with a very real example.
Back in 2010, Britain was fined more than £150m by the EU for failing to display the European flag on a string of Brussels funded projects.
There are apparently very strict rules on how the EU flag must be plastered over any piece of infrastructure, funded in any way by the EU.
Let me put it another way, you pay me £1000 because I say you have to.
I then give you a £10 contribution back towards fixing your roof.
I then fine you an extra £5 because you didn’t show me enough gratitude.
