Hubble Deep Field: The Most Imp. Image Ever Taken (Redux)

This is the latest incarnation of the HDF video. The narration has been edited to include research from a paper in Physical Review Letters (2004) which puts the size of the universe at 46.5 billion light years, not 78 billion as I originally stated. In the video narration, I round that value up to 47 billion light years.

The Universe is a strange place

About the Lecture Perhaps the universe is not so much strange as brimming with lovely paradox. The search for such beauty seems to lie at the heart of Frank Wilczek’s work. Twentieth century physics, from Einstein through Wilczek’s own Nobel Prize-winning efforts, involves demonstrating the existence of a topsy-turvy reality: for instance, that such sub-atomic particles as quarks and gluons, which have little or no mass, “orchestrate themselves into not just protons and neutrons but you and me,” according to Wilczek. “How is it possible to construct heavy objects out of objects that weigh nothing?,” he asks. Only by “creating mass out of pure energy.” These particles are essentially “excitations in otherwise empty space.” Says Wilczek: “That suggests something …beautiful and poetic: the masses of particles are not like, or similar to or metaphorically suggested by—they are the tones or frequencies of vibration patterns in dynamical voids.” The theory of quarks and gluons and the strong interaction accounts quantitatively for “the mass of protons, neutrons and ultimately you and me and everything around us.” But physics has not yet squared away all aspects of the universe. Wilzcek says that “in cosmology, we meet our match, and don’t know what’s going on.” This is because scientists can’t account for much of the mass in the cosmos. 70% of this mass is in “dark energy,” which is pushing the universe apart. Wilczek hopes that explanations for the dark stuff will emerge through improving equations, unifying theories of different interactions and extending their symmetries. “Beautifying equations leads not to ugly consequences but beautiful surprises,” he concludes.

Universe 114 Beyond Big Bang 47 Galileo

The History Channel Australia & New Zealand The Universe : 1/14 Beyond The Big Bang : 4/7 Galileo Learn about Galileo's bold moves of challenging the church with his theories of the universe. --- It all began inside a violent, blinding explosion that threw everything into chaos. Ever since, our greatest thinkers have peered into that chaos in search of order, logic & the answers to where we began. As earlier generations learned to decipher the cosmic clues of how we came to be, we stepped from revelation to revelation; epiphany to epiphany. Aristotle told us the world was round. Ptolemy conceived of a system of planets, stars & sun. Copernicus placed the sun at the center of this system. Galileo confirmed it. Newton explained what held it all together. Einstein offered insight into what fueled it. Hubble proposed it started with a "Big Bang". Our search for answers has shaped how we have evolved as thinking creatures. The Big Bang is the history of why & how we think about who & what we are. We'll contemplate how various cultures believe the world began & how it will all end...& what comes after. & for the first time, we'll be able to see what it might have all looked like, sitting in God's front row seats. Using unprecedented cutting edge animation, The Big Bang will recreate that amazing moment when everything started. With interviews from the world's leading physicists, engineers & historians we will employ every storytelling tool to make complex & confusing ideas clear, exciting & dramatic. Recreations, visual metaphors & first-person accounts will explain concepts like: the formation of galaxies, the existence of other dimensions & the idea of a parallel universe. The Big Bang will pose one of history's greatest questions, Where do we begin? --- http://www.thehistorychannel.com.au

Carl Sagan - 'A Glorious Dawn' ft Stephen Hawking (Cosmos Remixed)

My own musical tribute to two great men of science. Carl Sagan and his cosmologist companion Stephen Hawking present: A Glorious Dawn - Cosmos remixed. Almost all samples and footage taken from Carl Sagan's Cosmos and Stephen Hawking's Universe series. RIP Dr. Sagan, you will be missed!! Please, click HQ to watch in better quality. Go here to download the track: http://www.symphonyofscience.com And here for another scientist remix: http://www.youtube.com/watch?v=XGK84Poeynk And my website for more original music: http://www.colorpulsemusic.com/ Enjoy!! -John boswelj3@gmail.com Lyrics: [Sagan] If you wish to make an apple pie from scratch You must first invent the universe Space is filled with a network of wormholes You might emerge somewhere else in space Some when-else in time The sky calls to us If we do not destroy ourselves We will one day venture to the stars A still more glorious dawn awaits Not a sunrise, but a galaxy rise A morning filled with 400 billion suns The rising of the milky way The Cosmos is full beyond measure of elegant truths Of exquisite interrelationships Of the awesome machinery of nature I believe our future depends powerfully On how well we understand this cosmos In which we float like a mote of dust In the morning sky But the brain does much more than just recollect It inter-compares, it synthesizes, it analyzes it generates abstractions The simplest thought like the concept of the number one Has an elaborate logical underpinning The brain has its own language For testing the structure and consistency of the world [Hawking] For thousands of years People have wondered about the universe Did it stretch out forever Or was there a limit From the big bang to black holes From dark matter to a possible big crunch Our image of the universe today Is full of strange sounding ideas [Sagan} How lucky we are to live in this time The first moment in human history When we are in fact visiting other worlds The surface of the earth is the shore of the cosmic ocean Recently we've waded a little way out And the water seems inviting --------------------------------------- Watch Cosmos for free on Hulu: http://www.hulu.com/cosmos Carl Sagan's Mii Character #(for Wii): 6774-1898-8986

Stephen Hawking - We must colonize space in order to survive

Note: I edited this video, here is the full 10mins. Stephen Hawking: Asking big questions about the universe http://www.youtube.com/watch?v=xjBIsp8mS-c http://www.ted.com In keeping with the theme of TED2008, professor Stephen Hawking asks some Big Questions about our universe -- How did the universe begin? How did life begin? Are we alone? -- and discusses how we might go about answering them. PLEASE SUBSCRIBE TO: http://www.youtube.com/user/TEDtalksDirector "Since, in the long run, every planetary civilization will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring--not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive... If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds." Carl Sagan, Pale Blue Dot, 1994 "We need the stars... We need purpose! We need the image the Destiny [to take root among the stars] gives us of ourselves as a purposeful, growing species. We need to become the adult species that the Destiny can help us become! If we're to be anything other than smooth dinosaurs who evolve, specialize and die, we need the stars.... When we have no difficult, long-term purpose to strive toward, we fight each other. We destroy ourselves. We have these chaotic, apocalyptic periods of murderous craziness." Octavia Butler, Parable of the Talents, 1998 "I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars." Stephen Hawking, interview with Daily Telegraph, 2001 "The dinosaurs became extinct because they didn't have a space program. And if we become extinct because we don't have a space program, it'll serve us right!" Larry Niven, quoted by Arthur Clarke in interview at space.com, 2001 "In time, [a Martian] colony would grow to the point of being self- sustaining. When this stage was reached, humanity would have a precious insurance policy against catastrophe at home. During the next millennium there is a significant chance that civilization on Earth will be destroyed by an asteroid, a killer plague or a global war. A Martian colony could keep the flame of civilization and culture alive until Earth could be reverse- colonized from Mars." Paul Davies, The New York Times, 2004 "We must turn our guns away from each other and outwards, to defend the Earth, creating a global and in space network of sensors and telescopes to find asteroids that could destroy our planet and create the systems to stop them. It makes no sense to dream great dreams while waiting to be hit by a train." Buzz Aldrin and Rick Tumlinson, Ad Astra Online, 2006
