The question is, you know, how much light is out there and that's our primary thing is to say, you know, this is what we see. And we did a due diligence to try to explain what was there. The usual thing people do is they look at faint galaxies as you can see with the Hubble Space Telescope and other large telescopes. And you integrate that up and you say, well, this is what we see and these faint galaxies should provide such and such light. The most obvious thing is that galaxies, you know, that they're more galaxies of the other simple extrapolations because their properties change when they're small or something like that. It's starlight of one form and another just not where we think it is. And so one possibility is that JWST will see more galaxies than expected and you know, if it does, hopefully it's right on, we said they're totalists.
