The death star.

Out in deepest space lurks a force of almost unimaginable power. Explosions of extraordinary violence, are blasting through the Universe every day. If one ever struck our Solar System it would destroy our Sun and all the planets.

For years no one could work out what was causing these awesome explosions. Now scientists think they have identified the culprit. It's the most extreme object ever found in the Universe; they have christened it a 'hypernova'.

The nature of existence.

This is an "ex nihilo" derivation of existence as the geometric embodiment of a simple integer count. Possible mechanisms are given for the nuclear, weak, electromagnetic and gravitational interactions as well as cosmological observations.

Dark matter and dark energy are two of the most vexing problems in science today. Together they dominate the universe, comprising some 96 percent of all mass and energy. But nobody knows what either is.

Dark matter was invoked decades ago to explain why galaxies hold together. Given regular matter alone, galaxies might never have formed, and today they would fly apart. So there must be some unknown stuff that forms invisible clumps to act as gravitational glue.

Dark energy hit the scene in the late 1990s when astronomers discovered the universe is not just expanding, but racing out at an ever-faster pace. Some hidden force, a sort of anti-gravity, must be pushing galaxies apart from one another in this accelerated expansion.

David Deutsch: - What is our place in the cosmos?

In this rare (and delightfully engaging) public appearance, legendary physicist David Deutsch weaves a complex and captivating argument placing the study of physics at the center of our species' survival. Deutsch is author of "The Fabric of Reality" and the leading proponent of the multiverse intrepretation of quantum theory - the astounding idea that our universe is constantly spawning countless numbers of parallel worlds.

Immanuel Velikovsky - The bonds of the past.

Immanuel Velikovsky proposed in his 1950's book "Worlds in Collision" that many myths and traditions of ancient peoples and cultures are based on actual events: worldwide global catastrophes of a celestial origin, which had a profound effect on the lives, beliefs and writings of early mankind. He is best known as the author of a number of controversial books reinterpreting the events of ancient history, and in particular the US bestseller Worlds in Collision, published in 1950.

His books use comparative mythology and ancient literary sources (including the Bible) to argue that Earth has suffered catastrophic close-contacts with other planets (principally Venus and Mars) in ancient times. Velikovsky argued that electromagnetic effects play an important role in celestial mechanics.

This is a documentary about Immanuel Velikovsky's discoveries by Henry Zemel. First telecast on February 22, 1972 by the Canadian Broadcasting Corporation.

Cosmological origins: the universe, galaxies, and stars.

The March 13, 2007 Volunteer Enrichment Committee lecture at the Denver Museum of Nature & Science by Curator of Space Science Dr. Ka Chun Yu.

This lecture covers the 13.7 billion year history of the Universe, including topics on cosmology (relativity, the expansion of the universe, the aftermath of the Big Bang, inflation, the cosmic microwave background radiation, formation of the elements), and the evolution of the universe's contents afterwards (large structure formation, the evolution of galaxies, the roles of dark matter and dark energy). The talk ends with star formation covering molecular clouds.

The big question...

In this 20 min program narated by Stephen Hawking, we take look at the origin of the universe as is understood by modern science and largely thanks to Hawking's contribution to this field of research.

The big question - How did the universe begin?

The electric universe.

The Thunderbolts Project calls into question not only countless modern scientific assumptions, but also the billions of dollars of big-science government and corporate funding that continues to preserve and entrench questionable theories - elevating them to the status of doctrine - while systematically excluding legitimate alternatives that threaten the status-quo. Alternatives that may represent the future of science.

The Thunderbolts Project offers remarkably simple explanations for 'black holes', 'dark matter', the electric sun, comets that are NOT made of ice, planetary scarring and many other 'mysterious' phenomena.

It proposes that much of the currently observable phenomena of deep space can be intelligently explained by already known principles of electricity. High school students get it immediately. A doctorate in higher math is not required.

This extraordinary new theory also redefines ancient history, linking rock art images carved in basalt 5,000 years ago with identical images found only in Hubble photographs of deep space or in photographs of recently declassified high-energy plasma discharge experiments generated in a billion dollar lab.

Doppler effect & The Big Bang.

This lecture is part of a serie of 36 video lectures on Electricity and Magnetism, by Professor Walter Lewin, they were recorded on the MIT campus during the Spring of 2002. Prof. Lewin is well-known at MIT and beyond for his dynamic and engaging lecture style.

The Big Bang is a cosmological model of the universe that has become well supported by several independent observations. After Edwin Hubble discovered that galactic distances were generally proportional to their redshifts in 1929, this observation was taken to indicate that the universe is expanding.

Ironically, the term 'Big Bang' was first coined by Fred Hoyle in a derisory statement seeking to belittle the credibility of the theory that he did not believe to be true. However, the discovery of the cosmic microwave background in 1964 was taken as almost undeniable support for the Big Bang.

Analysis of the spectrum of light from distant galaxies reveals a shift towards longer wavelengths (Doppler effect) proportional to each galaxy's distance in a relationship described by Hubble's law, which is taken to indicate that the universe is undergoing a continuous expansion.

Super massive black holes.

A super massive black hole is a black hole with a mass in the range of hundreds of thousands to tens of billions of solar masses. It is currently thought that most, if not all galaxies, including the Milky Way, contain a super massive black hole at their galactic center.
