   And so, yes, people have wondered about the possibility that maybe, just maybe, what happens is the following. In most of these other universes, the fundamental constants of nature in those realms are such that the kinds of structures necessary for living systems, uh stable planet, stable stars, certain biomolecules, at least life as we know it. They give rise to amino acids that give rise to the nucleotides of DNA and so forth. Maybe in the vast majority of those other universes, those structures can't form because the constants of nature are different, and with those particular values, you d…

   Even in this case, we don't know how long they will be compared to things in the past. So take Einstein and his special theory of relativity. There was a real puzzle that he faced which had to do with properties of light and its motion. He wrote down some mathematical ideas just out of his head and thinking about the data and the situation and very quickly those ideas could be tested. In the general theory of relativity 10 years later he writes down equations to try to gain some insight into problems to do with the force of gravity. Within four years you could test those predictions through th…

   And that would be a very beautiful resolution to all of this. We've yet to find anything like that equation. Would we have to rule out those possibilities? Because s such an equation would say that all of these trillions of other potential ways of organizing the universe actually can't obtain. Uh we just didn't realize it before. Would we have to show its impossibility in that sense to show that it didn't in fact exist? Or is there a world in which we can prove actually they are all definitely possible and yet we know that they don't exist? Sure, it could just be historical contingency. If we …

   Certainly if it was a a hydrogen molecule or something like that, well, that would be an enormously long time. Two places at one longer than the current age of the universe from the Big Bang to now. So, it's it's much longer than that. Whereas if you were looking at the an amoeba, I'd have to think about it, you see. I think for an amoeba I'm not sure. Certainly if you're if you're thinking about uh I mean, you're getting up to the scale where the collapse times can be very rapid. If you had a grain of sand, it would be a ridiculously small fraction of a second. So, it's very small. And if you…

   Now to the uh proverbial uh the implications of the dark energy changing is are astonishing if indeed it's true. There are many things that can happen. The cosmological constant can slowly change sort of asmtoically changing to some value. It could get bigger. It could get smaller, right? It changes. It's not going to be a constant. It won't be a constant, right? So, the dark energy term will evolve. Can't evolve. We parameterize it by these two terms, omega or wa. Those are both the equations of state which govern the existence and the the net effect of the scale factor on distance. How the s…

   You can collect evidence forever, any kind  of empirical evidence you could ever imagine. And   the idea of that not being enough to pin down  what the universe is like, that's something   that naturally pops up in theories of space and  time. So I don't think GR is special here. I think   you can prove a similar kind of theorem pretty  much in any space-time theory that's modeled on   a manifold with geometric structures on it.  So a Newtonian version of space-time physics,   you'd have similar results there. So I&nbsp…

   That's all pretty good. But if you then said to me, but in that theory you've made certain assumptions. Yes, you assume there's electrons, neutrinos, why those particles and not others. And that really comes down to the question that Einstein really asked in a way. Is there a unique universe that somehow is logically required to be and any deviation from that universe would somehow be logically inconsistent? Einstein said did God have any choice in creating the universe? Could God therefore, in other words, have created the universe differently? Or was God's choices fixed by some sort of maste…

   It’s the one feature of physics which you can cancel by free fall, and that feature is incompatible with the principle of superposition. And you can make a little argument to show that they're inconsistent with each other and to make them consistent with each other, you have to introduce this collapse of the wave function. It also gives you a measure of how much when you expect the collapse to take place. And it's not not a complicated problem, there's a formula I produced which was actually not original with me, because Lajos Diósi had already found this formula about two years earlier than I…

    This raises the question of how far we can rely on extrapolating a theory to a new domain. For example, despite its success in describing objects moving with low relative velocities in a weak gravitational field, where it is nearly indistinguishable from general relativity, Newtonian gravity does not apply to other regimes. How far, then, can we rely on a theory to extend our reach? The obstacles to making such reliable inferences reflect the specific details of particular domains of inquiry. Below we will focus on the obstacles to answering theoretical questions in cosmology due to the struct…
