Cosmic Inflation and The Big Bang: What Scientists Aren't Telling You In this comprehensive video, we tackle the intricate relationship between theology and physics, focusing on the Big Bang Theory and its controversial origins. Proposed by a Catholic priest, the theory sought to merge the concept of creation ex nihilo with scientific thought. Over the years, it has faced numerous scientific hurdles, such as the Horizon problem, which led to the introduction of cosmic inflation—a hypothesis suggesting a brief period where the laws of physics did not apply. The James Webb Space Telescope's recent discoveries have added another layer of complexity, showing large, mature galaxies where we expected to find simple, young ones. We'll explore what these findings mean for both science and religion, offering a nuanced perspective on the creation of the universe.

Machine learning cosmic inflation by Ahana Kamerkar et al. on Tuesday 29 November We present a machine-learning approach, based on the genetic algorithms (GA), that can be used to reconstruct the inflationary potential directly from cosmological data. We create a pipeline consisting of the GA, a primordial code and a Boltzmann code used to calculate the theoretical predictions, and Cosmic Microwave Background (CMB) data. As a proof of concept, we apply our methodology to the Planck CMB data and explore the functional space of single-field inflationary potentials in a non-parametric, yet analytical way. We show that the algorithm easily improves upon the vanilla model of quadratic inflation and proposes slow-roll potentials better suited to the data, while we confirm the robustness of the Starobinsky inflation model (and other small-field models). Moreover, using unbinned CMB data, we perform a first concrete application of the GA by searching for oscillatory features in the potential in an agnostic way, and find very significant improvements upon the best featureless potentials, $Delta chi^2 < -20$. These encouraging preliminary results motivate the search for resonant features in the primordial power spectrum with a multimodal distribution of frequencies. We stress that our pipeline is modular and can easily be extended to other CMB data sets and inflationary scenarios, like multifield inflation or theories with higher-order derivatives. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.14142v1

The universe developed from a tiny speck (hypothetically containing the entirety of space) into something much, much bigger. Cosmic inflation explains how this occurred uniformly in spite of the rapidness of the process.

In the beginning was the Big Bang: an unimaginably hot fire almost fourteen billion years ago in which the first elements were forged. The physical theory of the hot nascent universe--the Big Bang--was one of the most consequential developments in twentieth-century science. And yet it leaves many questions unanswered: Why is the universe so big? Why is it so old? What is the origin of structure in the cosmos? In An Infinity of Worlds: Cosmic Inflation and the Beginning of the Universe (MIT Press, 2022), physicist Will Kinney explains a more recent theory that may hold the answers to these questions and even explain the ultimate origins of the universe: cosmic inflation, before the primordial fire of the Big Bang. Kinney argues that cosmic inflation is a transformational idea in cosmology, changing our picture of the basic structure of the cosmos and raising unavoidable questions about what we mean by a scientific theory. He explains that inflation is a remarkable unification of inner space and outer space, in which the physics of the very large (the cosmos) meets the physics of the very small (elementary particles and fields), closing in a full circle at the first moment of time. With quantum uncertainty its fundamental feature, this new picture of cosmic origins introduces the possibility that the origin of the universe was of a quantum nature. Kinney considers the consequences of eternal cosmic inflation. Can we come to terms with the possibility that our entire observable universe is one of infinitely many, forever hidden from our view?

What would it have been like to be an eyewitness to the Big Bang? In 2014, astronomers using the powerful BICEP2 telescope at the South Pole thought they'd glimpsed evidence of the period of cosmic inflation at the beginning of time. Millions around the world tuned in to the announcement, and Nobel whispers spread like wildfire. But had these scientists been deceived by a galactic mirage? In this popular-level talk, cosmologist Brian Keating tells the inside story of BICEP2's detection and the ensuing scientific drama. He provocatively argues that the Nobel Prize actually hampers scientific progress by encouraging speed and competition while punishing inclusivity, collaboration, and bold innovation.    Dr. Keating is s a cosmologist at the University of California San Diego and Principal Investigator of the Simons Observatory collaboration in Chile.  He is the author of a popular book, Losing the Nobel Prize: A Story of Cosmology, Ambition, and the Perils of Science's Highest Honor.This talk was recorded on Nov. 14, 2018.

How did it all begin? (And how will it all end?) How was our universe created - and how did we come to be? In today's episode, we'll answer these momentous questions using the monumental Big Bang theory: a theory not only describing the birth of our universe, but also its subsequent expansion and growth from a baby universe to the vast, expansive beauty we know it as today. So how did our universe go through puberty? Well, tune in today to find out!

Welcome back to another week and another episode. Today I thought we would break down the complicated and fascinating phenomenon known as cosmic inflation.

Today we’re going investigate the past — the most distant past imaginable: the Origin of the Universe. “How did the universe form” is such a profound question, that it informs everything we do today, and everything that will come next. My guest is James Bock. James is a Caltech Professor of Physics and NASA JPL Senior Research Scientist running experiments on what happened right after the Big Bang. As a leading cosmologist and astrophysicist, he and his team are at the forefront of understanding how the universe came to be. Today we explore how the universe formed, how such research is conducted, and why understanding the origins of the universe is important. More on James and his work at: http://cosmology.caltech.edu/ More at: https://www.MindAndMachine.io

Some recent detection of polarized light in the cosmic background radiation has been strong evidence for a particular theory about the origin of the universe called “cosmic inflation theory.” That’s pretty badass.

BICEP - gravitational waves and dust One of the biggest scientific claims of 2014 has received another set-back. In March this year, the BICEP2 research team claimed it had found a swirling pattern in the sky left by the rapid expansion of space just fractions of a second after the Big Bang. This announcement was quickly criticised by others, who thought the group had underestimated the confounding effects of dust in our own galaxy. And now, new analysis from the European Space Agency's Planck satellite suggests dust found in our own galaxy may have confounded what was thought to be a universal revelation. India's Mars satellite enters orbit India has successfully put a satellite into orbit around Mars, becoming the fourth nation or geo-bloc to do so. Following a few teething troubles with a planned engine burn shortly after launch on 5 November 2013, and a long journey, the Mangalyaan probe has started sending back images of the Red Planet. It is the first time a maiden voyage to Mars has entered orbit successfully and it is the cheapest mission to-date.

Astronomers have detected evidence of the young Universe’s formative growth spurt in the moments following the Big Bang. After more than a decade of observations and data analysis with a South Pole telescope called BICEP2, researchers detected distortions left in ancient light, the first direct evidence of the sudden and dramatic change that launched the Universe as we know it.

Last Monday, astronomers announced what has been described as "the biggest thing since dark energy" - detection of gravitational waves from the afterglow of the big bang. We got astronomer Dr. Alan Duffy from Swinburne University on to tell us what that means, and what it says about the very early stages of our Universe.

Cosmic Inflation and Gravity waves Scientists in the BICEP 2 Group say they've found the earliest rumbles of the Big Bang. Theory predicts how the universe first expanded. Now we have the first observation of the phenomenon behind it. The universe was kick-started by a so called 'inflation' - vigorous growth within a fraction of a second of the Big Bang going bang. To confirm inflation you need to detect ripples in the fabric of space called gravitational waves. And to find those, you need to look for twists and kinks in this stuff. The BICEP 2 radio telescope, at the South Pole, has been measuring the direction of twists of light from the Cosmic Microwave Background Radiation - which is a form of primordial light, a remnant of the Big Bang. The signals have been released that show distortions in that light that can only have been caused by gravitational waves. They could only be there if there was inflation. In other words, these observations have shored up one of the most important theories in cosmology. Gareth Mitchell discusses what this means with BBC Science Correspondent Jonathan Amos and Astronomer at UCL Dr. Hiranya Peiris.Photonic Radar As the search closes in on missing Malaysia Airlines flight MH 370, radar technology has been in the spotlight.

Professor David Stupples, a radar expert from City University, London, explain that this cheaper, more accurate technology could end up in your car.Show Us Your Instrument - Infrared camera Infrared cameras detect heat, and process this as a colourful image. Dominic McCafferty, from Glasgow University, uses this kit to study stress levels in birds. When an animal is stressed, blood is drawn away from its skin and routed to the essential organs. This 'fight or flight' reflex means the temperature of certain parts of the animal drops. The infrared camera measures this, providing a non-invasive way of testing an animal's stress level. Current projects include one to test chickens, aiming to improve their welfare.Water research When listener Dave Conway emailed in to ask about what research is being done on water, if any - we went straight to materials scientist Professor Mark Miodownik at UCL to find out.Taxidermy Is taxidermy a dying art?

May 18, 2011 Dr. Anthony Aguirre (University of California at Santa Cruz)  Our improving understanding of the cosmos points to an early epoch during which the universe expanded at a stupendous rate to create the vast amount of space we can observe. Cosmologists are now coming to believe that this “cosmic inflation” may do much more: in many versions, inflation goes on forever, generating not just our observable universe but also infinitely many such regions with similar or different properties, together forming a staggeringly complex and vast “multiverse”. Dr. Aguirre traces the genesis of this idea, explores some of its implications, and discusses how scientists are seeking ways to test this idea.

Originally broadcast in Feb 2011, my conversation with theoretical physicist Anthony Aguirre on the new, more complex picture of the universe that cosmologists have been sketching out in recent years. Anthony gave some of the clearest explanations I've heard of eternal inflation, the multiverse and why the Big Bang might not have been the beginning of everything.

How did the Universe begin? What made it expand from the size of a grapefruit to billions of lightyears across in a fraction of a second after the Big Bang? And why did it stop? And is ours the only Universe? We ask cosmologists Hiranya Peiris and Matt Johnson.

Transcript: In 1981, MIT physicist Alan Guth was looking for possible explanations for the smoothness and flatness of the universe when he came up with the idea of cosmic inflation. Inflationary cosmology is an adjustment to the standard big bang model wherein the universe went through a period of extremely rapid or exponential expansion at a time ten to the minus thirty-five to ten to the minus thirty-three seconds after the big bang; that’s a billion-billion-billion-billionth of a second after the big bang. In this tiny iota of time the universe expanded by forty orders of magnitude from smaller than an atomic nucleus to the size of about a grapefruit. The cause of inflation was the energy derived from a phase transition, such as that occurs when ice turns into water, which is associated with the unification of three of the fundamental forces of nature: the weak nuclear force, the strong nuclear force, and the electromagnetic force.

Cosmologist Anthony Aguirre discusses the new, more complicated view of the universe described by the latest theories. The universe may be bigger, older and far stranger than previously thought. We discuss multiverses, eternal inflation, space-time wormholes and more.
