I talked to Dr. Andres Plazas-Malagon about your question.

My name is Dr. Andres Plazas-Malagon.

I'm a project scientist at SLAC National Accelerator Laboratory, which is a government laboratory managed by Stanford University.

And I am an observational cosmology.

I'm currently working with the Vera C. Rubin Observatory.

That's a great question.

The first thing that I thought is like, wow, this person already knows that the universe is expanding.

And I just want to just highlight that for a moment because it's so weird.
