   > get this exactly right, forgive me. One place. Is you can have things that are incredibly massive and require energies that we've never gotten to. So we wouldn't see them because we haven't gotten to enough energy equivalents to the mass that we actually see the objects in the phenomenon. Another thing that can happen is, is that things can be so weakly coupled that we can barely detect them. Neutrinos are all but dark matter. They're very weakly coupled. They're not, the ones we see

   Despite their high relative abundance in our Universe, neutrinos are the least understood fundamental particles of nature. In fact, the quantum properties of neutrinos emitted in experimentally relevant sources are theoretically contested

   Dark matter is exactly such a particle. We believe there are dark matter particles in the universe. Most of the mass of the universe by energy is dark matter. We believe that there are probably millions or billions of dark matter particles flying through this room right now and we don't care because they go right through. They do not interact with us. To affect our everyday lives in any way, this new particle would have to interact substantially with the particles that we know are in us like electrons, protons, and neutrons. So imagine there's some new interaction. There's a new particle that …

   And particularly if you're looking at a source of neutrinos like the sun, the sun is unleashing on us a ton of other stuff. There are many other particles coming at us from outer space. Protons and gamma rays and electrons. All this stuff leaves signals and detectors and we need to find ways of shielding ourself from that other stuff so that we're looking at just the neutrinos. So in fact what we do is we go deep under ground. So some of the detectors are a 1,000 or 2,000, 3,000 up to 7,000 feet below ground and what that does it it tends to shield us from this flux of other stuff. So on the v…

   You would see this rather dramatic display of a ring of light hitting the walls and that's actual data from that experiment where they see different types of neutrinos either electron type neutrino or (inaudible) type neutrinos interacting in the water and you can see the pattern of light on the walls of the tank. This was an earlier experiment I just put it in there because it has a scuba diver in it and I thought it'd be funny (laughter) Actually, one of the things that was significant about our discoveries with neutrinos from the sun is that there's not nearly enough so we don't really worr…

   Now add up all the other stars in the universe-- there are a lot of neutrinos passing through you. Okay. Neutrinos are a big form of the energy release of any star or any super nova. A lot of the phenomena we see out in the universe are releasing neutrinos. They are also producing, if you noticed in this little set of reactions I produced --it's listed here-- the heavier elements. Some of the elements that we have left to us, are left over from literally the big bang. We have protons and neutrons and they form slightly heavier things. We get up to helium and lithium, left over from the big ban…

   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 is surrounded by these bulbous objects. They are called photo-multiplier tubes and when a scientist that is working on this experiment is looking for are flashes of light when a neutrino from the sun or other source comes and interacts with the water and creates the electromagnetic equivalent of a sonic boom so it's a light boom and you see flash of light produced in this water from a neutrino interaction. So the entire thing you can think of is a camera facing in looking at this water target. It doesn't by any stretch go down 6,000 feet. That's really darn deep. I think that's about the th…

   Is there any chance we find out what dark matter actually is in our lifetime? Well, I won't go through the whole rigomeroll again. Yeah, absolutely. I mean, there are detectors now capable of detecting for instance this particle called an axion that I mentioned in various windows and parameter space and sure they could be successful that that might be where this all ends up. Similar question. Do you think string theory will be proven experimentally someday? And how much time do you currently spend on string theory research? So two questions. Part one, will it be experimentally proven someday? …

    If you poke the Higs field, it starts vibrating and you see a little particle called the Higs Bzon. We first successfully did that in 2012. Big news. Uh in Geneva, the Large Hydron Collider, we discovered the Higs Bzon. There are other particles that exist that we know about, but they're just heavier cousins of these particles. So there's not only an electron, there's also a muon and a tow. There's not only an up quark, there's a charm quark and a top quark, etc. All those heavier particles, if you made one right here, it would decay away in an instant. It would make these particles. So the cl…
