"When the COSMOS data was released in 2007, the team - led by Massey
- assumed these two factors were equivalent. Their analysis revealed
that gravitational tugs on light were stronger than anticipated, but
they put this down to a slightly higher concentration of ordinary and
dark matter in the survey's patch of sky than had been predicted."
"To look for potential deviations from general relativity, Bean
reanalysed the data and dropped the requirement that these two
components of gravity had to be equal. Instead the ratio of the two
was allowed to change in value. She found that between 8 and 11
billion years ago gravity's distortion of time appeared to be three
times as strong as its ability to curve space."
"Yet finding a deviation when the universe was less than half its
current age is odd - if general relativity had broken down at some
level, the signs should be most dramatic more recently, long after
the repulsive effect of dark energy overwhelmed the attractive powers
of gravity some 6 billion years ago."

What is happening appears to me to be the detection of partial
reverse gravitational lensing. I described reverse gravitational
lensing on page 25 here:

It is interesting that, when looking at a mirror matter star or
galaxy, we can look right through it - it is mainly invisible to us,
yet the light passing through it can be gravitationally lensed - in a
repulsive instead of attractive way. However, since black holes
create a halo of opposed gravitational charge matter, which can
condense into stars and then black holes, combined gravitational
lensing can occur in a single volume of space. The nature of such
lenses thus changes over very long time intervals.
