For years we've been trying to figure out how it all began, but have we finally figured out how everything came to be? + + + + + + + + Previous Episode: What Is Dark Matter’s Role In The Formation Of Galaxies?: youtu.be/vkMlH-6msfQ?list=PLwwOk5fvpuuLUsdHbX81DIAsiBqQrilX_ + + + + + + + + Sources: Brief History Of The Universe: www.astro.ucla.edu/~wright/BBhistory.html “The Planck time: 10-43 seconds. After this time gravity can be considered to be a classical background in which particles and fields evolve following quantum mechanics." What Is the Big Bang Theory?: www.space.com/25126-big-bang-theory.html “The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it talks about the universe as we know it starting with a small singularity, then inflating over the next 13.8 billion years to the cosmos that we know today." How Are Light And Heavy Elements Formed?: curious.astro.cornell.edu/about-us/84-the-universe/stars-and-star-clusters/nuclear-burning/402-how-are-light-and-heavy-elements-formed-advanced “The lightest elements (hydrogen, helium, deuterium, lithium) were produced in the Big Bang nucleosynthesis. According to the Big Bang theory, the temperatures in the early universe were so high that fusion reactions could take place." Planck Mission Brings Universe Into Sharp Focus: www.nasa.gov/home/hqnews/2013/mar/HQ_13-079_Planck_Mission.html “The Planck space mission has released the most accurate and detailed map ever made of the oldest light in the universe, revealing new information about its age, contents and origins." How the Big Bang Theory Works: science.howstuffworks.com/dictionary/astronomy-terms/big-bang-theory4.htm “Because of the limitations of the laws of science, we can't make any guesses about the instant the universe came into being. Instead, we can look at the period immediately following the creation of the universe." The Universe Is 13.82 Billion Years Old: www.slate.com/blogs/bad_astronomy/2013/03/21/age_of_the_universe_planck_results_show_universe_is_13_82_billion_years.html “The Universe is a wee bit older than we thought. Not only that, but turns out the ingredients are a little bit different, too. And not only that, but the way they’re mixed isn’t quite what we expected, either." The Big Bang: science.nasa.gov/astrophysics/focus-areas/what-powered-the-big-bang/ “Astronomers combine mathematical models with observations to develop workable theories of how the Universe came to be." First Light & Reionization: jwst.nasa.gov/firstlight.html “Why is a powerful infrared observatory key to seeing the first stars and galaxies that formed in the universe? Why do we even want to see the first stars and galaxies that formed?" Our Expanding Universe: Age, History & Other Facts: www.space.com/52-the-expanding-universe-from-the-big-bang-to-today.html “The universe was born with the Big Bang as an unimaginably hot, dense point. When the universe was just 10-34 of a second or so old — that is, a hundredth of a billionth of a trillionth of a trillionth of a second in age — it experienced an incredible burst of expansion known as inflation, in which space itself expanded faster than the speed of light." + + + + + + + + DNews Plus is built for enthusiastic science fans seeking out comprehensive conversations on the geeky topics they love.
