[Excerpt] In this excerpt from his new book, Our Mathematical Universe, M.I.T. Instead of a Universe made up of 73% dark energy, the best post-Planck estimate puts it at just 68-to-69%. Physicists and astrophysicists at Los Alamos are using supercomputers to simulate Big Bang nucleosynthesis and the early universe to unprecedented precision. Everywhere in the universe, material objects are composed of atoms of the same types found here on Earth. The elements essential to life on earth (carbon, oxygen, hydrogen, nitrogen, etc.) The Universe is a big, open place. The atoms around you have existed for billions of years -- and most originated in the flaming, gaseous core of a star. Dennis Wildfogel tells the captivating tale of these atoms' long journeys from the Big Bang to the molecules they form today. Even the smallest things on Earth are part of the Universe. If we look at the human body and go down the scale we find cell, molecules, atoms, sub-atomic particles and pure energy. The whole universe is made up of energy - and at this level everything is vibrating. WMAP determined that about 4.6% of the mass and energy of the universe is contained in atoms (protons and neutrons). In a way, it is not so much the visible things that define the Universe, but rather the void around them. Estimates of the age of the Universe depend upon what it is made of. The universe is hiding something. Such contents comprise all of energy in its various forms, including electromagnetic radiation and matter, and therefore planets, moons, stars, galaxies, and the contents of intergalactic space. Scientists Respond All this week, we've been contemplating the great mysteries of the universe. But it is just not made up of atoms. Starting in the 1970s, astronomers began collecting evidence that made them suspect there was more to the universe than meets the eye. In Tegmark's view, everything in the universe — humans included — is part of a mathematical structure. It is made of many millions of millions of stars and planets and enormous clouds of gas separated by a gigantic space.. Astronomers can use telescopes to look at very distant galaxies.This is how they see what the Universe looked like a long time ago. Almost all of the universe — 96 percent — is invisible stuff called dark matter and dark energy. The fraction of the universe that we think is made of the same particles as astronomy students has been decreasing steadily. In fact, it is hiding a lot. Existing space and ground-based telescopes have made substantial progress in studying the subsequent evolution of galaxies. During the Big Bang, all of the space, time, matter, and energy in the Universe was created. However, the elements that we are familiar with are just part of the story. The amounts of hydrogen, helium, and lithium that are made depend on what these other particles might be. TED Talk Subtitles and Transcript: The atoms around you have existed for billions of years -- and most originated in the flaming, gaseous core of a star. Only 4.6 percent of the universe is made from ordinary atoms, the other 95.4 … Approximately half of this percentage still eluded detection. If these results are correct, an unknown 75% of the Universe has been identified. Is the Universe Made of Math? This book aims to be as simple as possible, but not at the risk of inaccuracy or dumbing-down. also exist on planets around other stars. Matter known as ordinary corresponds to only 5 percent of the Universe. Hot gas mainly: 'Cosmic web' of filaments makes up the space between galaxies. The universe is composed almost completely of dark energy, dark matter, and ordinary matter. It aims to explain the basic structure of the universe, our place in it, and some of its core, basic workings. We don't even know how big the Universe is! The universe is made up of ordinary matter, dark matter and dark energy. [Directed by Pew36 Animation Studios, narrated by Dennis Wildfogel]. The Universe is all of time and space and its contents. What is the universe made of? A 2013 paper by MIT engineer Seth Lloyd builds the case for an intriguing spin on the concept: If space-time is made of quantum bits, the universe must be one giant quantum computer. Dennis Wildfogel tells the captivating tale of these atoms' long journeys from the Big Bang to the molecules they form today. The Universe Made Simple is a book that attempts to describe the universe to someone who knows little or nothing about it to start with. The Universe consists of hydrogen (75 %), helium (24 %) and a tiny smattering of heavier elements (1 %). When astronomers consider what it's made of, they can point most directly to the billions of galaxies it contains. Present day, we can say that Universe is made up of 72% Dark Energy, 23% Dark Matter, 4.6% Baryonic Matter. They are in the Universe. Both theory and observations indicate that the Universe contains huge amounts of dark matter; no one knows what it’s made … But what about the other 95 percent? They are very small. The universe is a vast and fascinating place. Yes, universe has atoms. Other contents are electromagnetic radiation (estimated to constitute from 0.005% to close to 0.01% of the total mass-energy of the universe) and antimatter." The physical universe is defined as all of space and time (collectively referred to as spacetime) and their contents. We aren't made of hydrogen! Humans are made of the stuff that everything else is made of in the universe. Astrophysicists tell that universe is made up of atoms. The biggest stars are in it. All of life is made from a portion of this 4.6%. Image to right: Amoebas live on Earth. According to physicists universe is made up of protons neutrons and electrons. Changing Estimates of the Content of the Universe: This diagram shows the changes in our understanding of the contents of the universe over the past three decades. (credit: modification of work by NASA/WMAP Science Team) What is the universe made of? Figure 2. Normal baryonic matter, the stuff most physicists study, makes up about 5% of the Universe. Baryonic matter, the ‘ordinary’ matter that we can encounter and see, accounts for just 5% of the total. The Earth, the sun, the stars, and everything we can see, only comprise five percent of the universe. You are in the Universe. Atoms are a small part of our universe. Cosmological and astrophysical observations indicate that most of the Universe is made up of invisible substances that do not emit electromagnetic radiation – that is, we cannot detect them directly through telescopes or similar instruments. The universe was then dark (except for this background radiation) until the first stars and galaxies began to form only a few hundred million years after the Big Bang. Things you can't see are in it, too. The only chemical elements created at the beginning of our universe were hydrogen, helium and lithium, the three lightest atoms in the periodic table. Thus, our new inventory gives us a new age for the Universe: 13.4 +/- 1.6 Gyr. The conventional answer is "Composition. The vast majority of the universe is invisible and, so far, undetectable. Most astronomers think that the Universe was formed during an event called the Big Bang - a giant explosion which occurred between 10 and 20 billion years ago. April 18, 2017. By studying the high-temperature and high-pressure environment of the early universe during BBN, we hope to better understand the particles present in the early universe … What Is The Universe Made Of? These protons, neutrons and electrons are bound together to form atom. [Directed by Pew36 Animation Studios, narrated by Dennis Wildfogel]. Matter known as ordinary, which makes up everything we know, corresponds to only 5% of the Universe. A curious combination of what scientists call dark matter and dark energy accounts for the remaining 95%. How was the Universe made?
