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.

Thunderbolts of the Gods

In science one of the best markers for the accuracy of a model or theory is how well it predicts outcomes. This applies not only to future events but can also be applied to existing data. Below is a collection of predictions based on Electric Universe principles, which have been confirmed by observations and data. The link above provides a list of pending predictions.

Stephen Hawking: Master of the Universe (Part 1 of 10)

In his post as Lucasian Professor of Mathematics at Cambridge University, he counts Sir Isaac Newton (1642--1727) amongst his predecessors. And he was born 300 years to the day after the avant-garde astronomer, Galileo Galilei (1564--1642). Following a devastating diagnosis of motor neurone disease in 1963, Hawking was given two years to live. Yet 44 years later, he still hopes to solve the big problem of physics, that of unifying quantum mechanics and Einstein's theory of relativity. Doing so will produce a set of laws that will explain everything in the universe, including how it all began - a breakthrough aptly dubbed the 'Theory of Everything'. Hawking felt that he was on the brink of this breakthrough a long time ago. When he published his surprising best-seller 'A Brief History of Time' in 1988, he expressed a certainty that the Theory of Everything was imminent. However, twenty years later, it still eludes Hawking and the scientific community. Frustratingly, Hawking's condition is worsening. His only way of communicating now is through one cheek muscle. Will he find the theory before it is too late? This two-episode documentary from the UK's Channel 4 is both a portrait of Hawking and an attempt to explain his work to non-scientific types. It conveys the basics of quantum mechanics and the theory of relativity in an easy-to-understand manner and does very well to acquaint viewers with Hawking's extraordinary life and character. A thoroughly enjoyable, inspiring and enlightening series!

1of5_Cosmic Odyssey-Hubble Heritage

This is part 1 of a 5 part episode. To watch the full show go to my channel (Zuke696) then go to my Playlist, find the show then click Play All - Hubble's Heritage - In 1929, astronomer Edwin Hubble made one of the greatest discoveries in the history of science -- the expansion of the universe. To honor this king of cosmology, an orbiting observatory named the Hubble Space Telescope was launched in 1990 after years of research and delay. Hubble's Heritage takes a closer look at this instrument, from its beginning as a flawed engineering nightmare to its evolution, through corrective optics, into humanity's eyes on the universe. Viewers see some of the astonishing images captured by the Hubble Space Telescope through the years and learn of their significance to astronomers. Designers of the next generation of space telescopes explain the challenges that must be met before Hubble's successors can reveal more mysteries of the universe.

The Electric Universe Pt3 of 4

Pulsars and Comets in the electric universe/plasma cosmology model. See this publication for some more info on this interpretation of pulsars, published and peer reviewed in the journal of astrophysics and space science; http://adsabs.harvard.edu/abs/1995Ap&SS.227..229H A pulsar (pulsating star) is an astronomical object which produces a regular pulse of radio waves (electromagnetic radiation) which is conventionally thought to be due to a rotating neutron star. The Plasma Universe explains pulsars as a magnetospheric transmission line system. Also see this website for more information on electrical activity associated with comets and some other evidence supporting the electric model (with peer reviewed references); http://www.plasma-universe.com/index.php/Comet
