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