Only 4.6 percent of the universe is made from ordinary atoms, the other 95.4 … 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. If these results are correct, an unknown 75% of the Universe has been identified. We don't even know how big the Universe is! The universe is hiding something. Astrophysicists tell that universe is made up of atoms. [Excerpt] In this excerpt from his new book, Our Mathematical Universe, M.I.T. In fact, it is hiding a lot. The biggest stars are in it. But it is just not made up of atoms. Baryonic matter, the ‘ordinary’ matter that we can encounter and see, accounts for just 5% of the total. All of life is made from a portion of this 4.6%. The conventional answer is "Composition. [Directed by Pew36 Animation Studios, narrated by Dennis Wildfogel]. In Tegmark's view, everything in the universe — humans included — is part of a mathematical structure. Is the Universe Made of Math? Present day, we can say that Universe is made up of 72% Dark Energy, 23% Dark Matter, 4.6% Baryonic Matter. We aren't made of hydrogen! 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. What is the universe made of? Matter known as ordinary, which makes up everything we know, corresponds to only 5% of the Universe. Even the smallest things on Earth are part of the Universe. Matter known as ordinary corresponds to only 5 percent of the Universe. The atoms around you have existed for billions of years -- and most originated in the flaming, gaseous core of a star. The amounts of hydrogen, helium, and lithium that are made depend on what these other particles might be. The Earth, the sun, the stars, and everything we can see, only comprise five percent of the universe. What Is The Universe Made Of? Dennis Wildfogel tells the captivating tale of these atoms' long journeys from the Big Bang to the molecules they form today. 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." Approximately half of this percentage still eluded detection. (credit: modification of work by NASA/WMAP Science Team) Existing space and ground-based telescopes have made substantial progress in studying the subsequent evolution of galaxies. When astronomers consider what it's made of, they can point most directly to the billions of galaxies it contains. Thus, our new inventory gives us a new age for the Universe: 13.4 +/- 1.6 Gyr. But what about the other 95 percent? Estimates of the age of the Universe depend upon what it is made of. 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. The vast majority of the universe is invisible and, so far, undetectable. The Universe is all of time and space and its contents. Image to right: Amoebas live on Earth. How was the Universe made? These protons, neutrons and electrons are bound together to form atom. Dennis Wildfogel tells the captivating tale of these atoms' long journeys from the Big Bang to the molecules they form today. If we look at the human body and go down the scale we find cell, molecules, atoms, sub-atomic particles and pure energy. 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. Normal baryonic matter, the stuff most physicists study, makes up about 5% of the Universe. 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. Humans are made of the stuff that everything else is made of in the universe. also exist on planets around other stars. However, the elements that we are familiar with are just part of the story. The only chemical elements created at the beginning of our universe were hydrogen, helium and lithium, the three lightest atoms in the periodic table. What is the universe made of? 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. You are in the Universe. According to physicists universe is made up of protons neutrons and electrons. They are very small. April 18, 2017. [Directed by Pew36 Animation Studios, narrated by Dennis Wildfogel]. 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 … Almost all of the universe — 96 percent — is invisible stuff called dark matter and dark energy. Physicists and astrophysicists at Los Alamos are using supercomputers to simulate Big Bang nucleosynthesis and the early universe to unprecedented precision. Instead of a Universe made up of 73% dark energy, the best post-Planck estimate puts it at just 68-to-69%. 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. Figure 2. The Universe is a big, open place. The elements essential to life on earth (carbon, oxygen, hydrogen, nitrogen, etc.) The whole universe is made up of energy - and at this level everything is vibrating. The Universe consists of hydrogen (75 %), helium (24 %) and a tiny smattering of heavier elements (1 %). Scientists Respond All this week, we've been contemplating the great mysteries of the universe. It aims to explain the basic structure of the universe, our place in it, and some of its core, basic workings. Both theory and observations indicate that the Universe contains huge amounts of dark matter; no one knows what it’s made … Atoms are a small part of our universe. 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. During the Big Bang, all of the space, time, matter, and energy in the Universe was created. 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. The universe is made up of ordinary matter, dark matter and dark energy. Yes, universe has atoms. WMAP determined that about 4.6% of the mass and energy of the universe is contained in atoms (protons and neutrons). A curious combination of what scientists call dark matter and dark energy accounts for the remaining 95%. The universe is a vast and fascinating place. 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 physical universe is defined as all of space and time (collectively referred to as spacetime) and their contents. Things you can't see are in it, too. Everywhere in the universe, material objects are composed of atoms of the same types found here on Earth. They are in the Universe. This book aims to be as simple as possible, but not at the risk of inaccuracy or dumbing-down. In a way, it is not so much the visible things that define the Universe, but rather the void around them. Starting in the 1970s, astronomers began collecting evidence that made them suspect there was more to the universe than meets the eye. The fraction of the universe that we think is made of the same particles as astronomy students has been decreasing steadily.
