Since buying his Bellway property in Bedfordshire a year ago, he has found patches of damp or discoloured tiles, accretions of moss and mould growing in the loft space.

Rather, the brain’s immune response contributes to neuroinflammation and increased accretion of amyloid and tau, which in turn leads to neurodegeneration.

“This was intriguing, but without a way to obtain spectra of those stars, we could not really establish whether we were witnessing genuine accretion and the presence of disks, or just some artificial effects.”

Their answer to this state of affairs will be the steady, unremitting accretion and employment of power — defined predominantly in military terms — to serve narrowly defined national interests.

Eventually the entire accretion disk is torn in half, with the black hole first consuming the inner disc and then the outer one.
