Rapid galaxy merging in early universe VS acceleration of expansion

In today's post, Andrew Yee announces a recent survey of galaxies
in the early universe, showing that mergers were the main action of
the day, as opposed to the current universe. He then notes the
surprising cessation of this heavy merger period as follows:

The results further show that massive galaxies did not form rapidly,
within a few million years after the Big Bang, or form gradually over an
extended period of time. In a surprising finding, almost all of this
merger activity occurs over a very short period of time, from the birth
of the universe to about six billion years ago.

Dr Conselice added: "Perhaps the most amazing thing about these results
is that massive galaxy formation is largely over when the universe is
half its current age. This means that all this merging activity was
somehow curtailed by an unknown process." ..."

I notice that this 'curtailment' of heavy mergers coincides roughly
with
most peoples' current estimate of the ONSET of the acceleration of the
expansion of the universe.

Can there be a causal connection here or is it mere coincidence?

There's a simple connection...
The Big Programmers didn't like all the mess in the Big Simulation due to
heavy galaxies mergers.
So some days ago (in their time scale) the Chief Architect put the variable
values:
Logical Accelerated_Expansion = True
Number Accelerated_Speed = Very_High

Great and easy job, the Big Simulated universe become very quiet and the
Sims (us) could develop their strange civilization.

Of course you can have some doubt, but do you think, for example, that,
these days, politics in Italy has something real?
It's clearly a Simulation Joke... :-)
