The experiment is like a radio receiver.
We have to tune it and find the right frequency, but we don't know what the frequency is.
Yes.
So we need to tune into it.
Yeah, yeah.
Give us a chance.
This is the biggest digital camera ever built.
Each image is 3.2 billion pixels.
The first images are just astonishing.
So not only are they super high resolution, but the depth is very great so that you can see much, much further into the universe.
So when you look at pictures of galaxies, for example, they look super crisp, but you can also see the force.
faint outskirts of these galaxies where gas is accumulating, which is going to feed into future generations of stars that we couldn't see before.
And also because it is a time lapse, you can see exploding stars in the universe.
We are going to use these images to map dark matter across half the sky and about halfway into the lifetime of the universe.
We can't see dark matter, but the presence of dark matter bends light when they encounter concentrations of matter.
So this causes tiny, tiny distortions in the shapes of galaxies.
which we can map.
So if you have billions of galaxies, you can back out the intrinsic shapes of the galaxies and extract the very, very faint dark matter signal and use that to map out how structure is evolving over the course of the universe's history.
So that's what we plan to do.
What is your role then on the project?
