   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…

   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…

   Sufficiently small fluctuations can be treated as linear perturbations to a background cosmological model, governed by an evolution equation that follows from EFE. Yet as the fluctuations grow larger, linearized perturbation theory no longer applies. According to the SM, structure grows hierarchically with smaller length scales going non-linear first, and larger structures forming via later mergers. Models of evolution of structures at smaller length scales (e.g., the length scales of galaxies) include physics other than gravity, such as gas dynamics, to describe the collapsing clumps of matte…

   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…

   Although statistical evidence is not overwhelming, possible support for an approximately 35×106 yr periodicity in the crater record on Earth could indicate a nonrandom underlying enhancement of meteorite impacts at regular intervals. A proposed explanation in terms of tidal effects on Oort cloud comet perturbations as the Solar System passes through the galactic midplane is hampered by lack of an underlying cause for sufficiently enhanced gravitational effects over a sufficiently short time interval and by the time frame between such possible enhancements. We show that a smooth dark disk in th…

   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…

   Using galaxy evolutionary models in a hierarchical formation scenario, we predict the structure, dynamics and evolution of disk galaxies in a LCDM universe. Our models include star formation and hydrodynamics of the ISM. We find that the Tully-Fisher relation (TFR) in the I and H bands is an imprint of the mass-velocity relation of the cosmological dark halos. The scatter of the TFR originates mainly from the scatter in the dark halo structure and, to a minor extension, from the dispersion of the primordial spin parameter lambda. Our models allow us to explain why low and high surface brightne…

   Analysis of the Planck 2018 data set indicates that the statistical properties of the cosmic microwave background (CMB) temperature anisotropies are in excellent agreement with previous studies using the 2013 and 2015 data releases. In particular, they are consistent with the Gaussian predictions of the $Λ$CDM cosmological model, yet also confirm the presence of several so-called "anomalies" on large angular scales. The novelty of the current study, however, lies in being a first attempt at a comprehensive analysis of the statistics of the polarization signal over all angular scales, using eit…

   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…

    In 1925, Hubble settled the issue by proving that the Andromeda Nebula existed outside of the Milky Way. It, along with other distant nebulas, were renamed "galaxies." ♪ ♪ DE SWART: The whole notion of a "galaxy" started to become a thing only in the mid-1920s. People started immediately get interested in what these things are. NARRATOR: Especially Edwin Hubble. He began measuring the distance from Earth to various galaxies, and when he combined his work with that of other astronomers, he discovered something deeply mysterious. It had to do with the Doppler effect. (distorted pitch shifting) W…
