what is the universe made of
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 … (credit: modification of work by NASA/WMAP Science Team) 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. If we look at the human body and go down the scale we find cell, molecules, atoms, sub-atomic particles and pure energy. During the Big Bang, all of the space, time, matter, and energy in the Universe was created. In fact, it is hiding a lot. We don't even know how big the Universe is! The amounts of hydrogen, helium, and lithium that are made depend on what these other particles might be. What Is The Universe Made Of? But what about the other 95 percent? The Universe is all of time and space and its contents. The universe is composed almost completely of dark energy, dark matter, and ordinary matter. These protons, neutrons and electrons are bound together to form atom. 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. [Directed by Pew36 Animation Studios, narrated by Dennis Wildfogel]. Baryonic matter, the ‘ordinary’ matter that we can encounter and see, accounts for just 5% of the total. Both theory and observations indicate that the Universe contains huge amounts of dark matter; no one knows what it’s made … What is the universe made of? How was the Universe made? Dennis Wildfogel tells the captivating tale of these atoms' long journeys from the Big Bang to the molecules they form today. The conventional answer is "Composition. The vast majority of the universe is invisible and, so far, undetectable. Matter known as ordinary corresponds to only 5 percent of the Universe. The Universe is a big, open place. 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. The universe is hiding something. The atoms around you have existed for billions of years -- and most originated in the flaming, gaseous core of a star. April 18, 2017. This book aims to be as simple as possible, but not at the risk of inaccuracy or dumbing-down. Dennis Wildfogel tells the captivating tale of these atoms' long journeys from the Big Bang to the molecules they form today. Approximately half of this percentage still eluded detection. The universe is a vast and fascinating place. 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. Thus, our new inventory gives us a new age for the Universe: 13.4 +/- 1.6 Gyr. The only chemical elements created at the beginning of our universe were hydrogen, helium and lithium, the three lightest atoms in the periodic table. Starting in the 1970s, astronomers began collecting evidence that made them suspect there was more to the universe than meets the eye. Instead of a Universe made up of 73% dark energy, the best post-Planck estimate puts it at just 68-to-69%. In a way, it is not so much the visible things that define the Universe, but rather the void around them. Is the Universe Made of Math? Atoms are a small part of our universe. Estimates of the age of the Universe depend upon what it is made of. Yes, universe has atoms. The biggest stars are in it. However, the elements that we are familiar with are just part of the story. Matter known as ordinary, which makes up everything we know, corresponds to only 5% of the Universe. They are in the Universe. 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 physical universe is defined as all of space and time (collectively referred to as spacetime) and their contents. Humans are made of the stuff that everything else is made of in the universe. We aren't made of hydrogen! 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. Image to right: Amoebas live on Earth. 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.
