   NARRATOR: Direct dark matter detection experiments go back to the 1980s. Xenon-based experiments, similar in design to LZ, to the 2000s. So far, all the experiments combined have detected nothing. But the process constantly narrows down what dark matter could possibly be. And currently, LZ has time on its side. The plan is to accrue a total of three years' worth of data. GHAG: Hopefully, there'll be a direct detection and we'll start to understand the nature of it. It could be that dark matter isn't a simple one-size-fits-all WIMP. It could be that there's multiple different types of dark matt…

   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 …

   I started graduate school in 1984 at Oxford where my son is starting in the fall which is fun. But I started graduate school in in 1984. The very first paper I wrote was a analysis of a potential dark matter candidate. It was sort of a straightforward research project for a beginning student. No one knows what the dark matter is. So make a guess, hypothesize a new kind of particle with new kinds of interactions to speak to the questioner's question and work out whether cosmologically enough of that stuff would still be around to supply the missing gravity that the astronomical observations req…

   Well, this debate, the multiverse universe debate. I see both sides assumed that all the laws of nature were fixed at the moment, the big bang and all the constants to a fixed one. As I've shown, the constants may vary. I discussed this in the science tradition, but also the laws don't have to be fixed if. The laws are like habits. They can evolve along with nature. They don't all have to be fixed at the moment. The Big Bang, the whole of this debate just dissolves away like the morning mist. If we have a view of the evolution of the habits of nature, then cosmologists have had to postulate da…

   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…

   This is a really hard problem. NARRATOR: There aren't many clues. Aside from its gravitational effect, dark matter appears to interact very little with normal matter, and can pass right through it. It also emits no electromagnetic radiation, no light. There are forms of matter that simply don't glow like stars do, but actually they're also not responding to light. So they are invisible, except through their gravitational force. It probably is something quite exotic. It isn't any of the ordinary stuff. NARRATOR: So who are the suspects for dark matter? There are the MACHOs; the Massive Compact …

   KÖNIG: The Hubble pictures tell us that the universe is the same everywhere. It's also a reminder that we are definitely not the center of the universe. NARRATOR: One of the most shocking discoveries of the last 50 years, was made in our own cosmic backyard. In 1998, astrophysicist Andrea Ghez and her team surprised the world when they revealed evidence of a super massive black hole at the center of our own Milky Way. GHEZ: From watching stars orbit the center of the galaxy, the mass that we infer is four million times the mass of the sun. That is the proof of a black hole. NARRATOR: Astronome…

    All chaotic energy states will either jump to a higher state, and stay there as long as the extra energy does, or it will ignore the extra force. When there isn't enough energy to maintain the element in this state, it drops to a specific lower state and sheds the excess energy. When this happens we see it as a burst of light which will be specific to each particular element. By examining the luminous evidence, astrophysicists can determine how much matter is shedding light. According to older theories all matter radiates light, and this could be used to determine how much matter was in Univer…
