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?
So I'm one of the people who is going to turn those pictures into conclusions about dark matter and dark energy.
So it's another statistical bridge, but because the volume and complexity of the data is so great, the statistics now has to be augmented by machine learning and very advanced AI techniques.
Absolutely.
It is a really nice way to think about it.
And thank you for making this connection.
Yes, that's right.
One of the missions is to find all the near-Earth asteroids and map their orbits so that we might be able to have an early warning of any potential collision.
When they were taking those first light pictures, Jim, that you said you found on the web, just 10 hours of observations just to get some beauty shots, they found 2,000 asteroids that had never been mapped before.
None so far heading towards Earth.
You can see them jiggling around on the sky.
And to me, this was just amazing because you feel that the solar system is just alive.
This still gives me goosebumps.
I think it'll be a complete bonanza.
