Right here behind us is where they're
building the proto-DUNE detector which
is a miniaturized prototype for a giant
mega science experiment that's going to
be built in the United States.
It's all about understanding why we're here,
how we got here, how the universe
has developed and potentially how it will develop in the future.
We know about the Big Bang and inflation
and how the universe came to be,  but in that
evolution from from time zero to today
there are certain questions which are still open.
What makes me love them is that
they are so abundant and so elusive.
They are so well defined that if you make a good detector where you can see them interacting
they give you spectacular signatures which are like, it's nice, it's clean,
it's a physicists dream.
It's really the first
time that a neutrino experiment goes to
this size, in terms of the collaboration also, because neutrino experiments have
always been smaller in terms of collaborators.
It's something no-one ever tried to achieve before.
So what they are doing is they build the models here,
they test them. They get all the kinks
out and then they scale up the
technology to 20 or 30 times as large.
The reason why particle physics and a lot of space science is
called "big science" is because you really
have to think ahead
plan, do a lot of development.  Do a lot of de-risking so that you know what you make works.
