If we look at the human body and go down the scale we find cell, molecules, atoms, sub-atomic particles and pure energy. Everywhere in the universe, material objects are composed of atoms of the same types found here on Earth. Is the Universe Made of Math? However, the elements that we are familiar with are just part of the story. They are in the Universe. The universe is composed almost completely of dark energy, dark matter, and ordinary matter. 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. Atoms are a small part of our universe. Both theory and observations indicate that the Universe contains huge amounts of dark matter; no one knows what it’s made … 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. 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. We aren't made of hydrogen! All of life is made from a portion of this 4.6%. Yes, universe has atoms. 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 amounts of hydrogen, helium, and lithium that are made depend on what these other particles might be. But it is just not made up of atoms. also exist on planets around other stars. Approximately half of this percentage still eluded detection. If these results are correct, an unknown 75% of the Universe has been identified. How was the Universe made? Hot gas mainly: 'Cosmic web' of filaments makes up the space between galaxies. We don't even know how big the Universe is! The physical universe is defined as all of space and time (collectively referred to as spacetime) and their contents. Matter known as ordinary, which makes up everything we know, corresponds to only 5% of the Universe. During the Big Bang, all of the space, time, matter, and energy in the Universe was created. The only chemical elements created at the beginning of our universe were hydrogen, helium and lithium, the three lightest atoms in the periodic table. When astronomers consider what it's made of, they can point most directly to the billions of galaxies it contains. Estimates of the age of the Universe depend upon what it is made of. The atoms around you have existed for billions of years -- and most originated in the flaming, gaseous core of a star. Normal baryonic matter, the stuff most physicists study, makes up about 5% of the Universe. In a way, it is not so much the visible things that define the Universe, but rather the void around them. Existing space and ground-based telescopes have made substantial progress in studying the subsequent evolution of galaxies. 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. The biggest stars are in it. These protons, neutrons and electrons are bound together to form atom. The elements essential to life on earth (carbon, oxygen, hydrogen, nitrogen, etc.) Even the smallest things on Earth are part of the Universe. Instead of a Universe made up of 73% dark energy, the best post-Planck estimate puts it at just 68-to-69%. What is the universe made of? [Excerpt] In this excerpt from his new book, Our Mathematical Universe, M.I.T. This book aims to be as simple as possible, but not at the risk of inaccuracy or dumbing-down. Humans are made of the stuff that everything else is made of in the universe. The universe is hiding something. 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." What is the universe made of? You are in the Universe. [Directed by Pew36 Animation Studios, narrated by Dennis Wildfogel]. The Universe is a big, open place. 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. Baryonic matter, the ‘ordinary’ matter that we can encounter and see, accounts for just 5% of the total. They are very small. It aims to explain the basic structure of the universe, our place in it, and some of its core, basic workings. 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. (credit: modification of work by NASA/WMAP Science Team) Starting in the 1970s, astronomers began collecting evidence that made them suspect there was more to the universe than meets the eye. 96 percent — is invisible and, so far, undetectable 's made of, they can point directly.
