Hubble Trouble with Hakeem Oluseyi

of the field are our particles, right? So there are the permanent ones and there are the virtual ones, right? So we measure the excitations as particles. As particles, right. Now here's what happens, though. They say, oh, there's this thing called a Higgs field. It's just there. It's just everywhere in space at all times. It's just there, right? Scalar field. No source.

And I'm like, in my mind, as a young scientist, I'm like, is that real? Then they discovered, they ring that damn field and create the particle. I'm like, wow. So now what can you do? Oh, inflation. Looks like Alan Guth creates inflation. Looks like the universe rapidly expanded. Oh, I know what I'll do. I'll create another scalar field. I call it the inflaton field.

So now you see some dynamics happening. You can just create a new field. So, but it sounds like you're pulling stuff out of your ass. It does. It does. But you're supposed to like use it to make predictions. So, you know, to test whether what came out of your ass is real.

I'll bring it to the next show. Oh, you remember the shit list from the 90s? No. Oh, it was like a joke, and it lived on the internet, the early internet, and it was like all these different types of shit. One of them was ghost shit. You felt it came out, you wiped, there's nothing on the toilet paper, there's nothing in the toilet, but you know what happened. Oh, wow, okay, okay.

So some people are doing that. They're saying maybe the universe's expansion rate hasn't just been what we think it is, as simple as we think it is.

Or each of those have to be adjusted. Well, there's an assumption within there as well that comes from the cosmological principle that the universe is isotropic and homogeneous. And now people are looking. If I look in that direction, I look in that direction, I look in that direction, is the expansion rate the same versus distance in every particular direction?

So, you know, that's why we have big surveys coming on like the Vera Rubin Telescope LSST because we typically have pencil beam surveys for the most part or surveys that don't go too deep.
