Marcus du Sautoy: Faster Than the Speed of Light?

Professor Marcus du Sautoy explores claims that scientists at CERN have detected particles which seem to travel faster than the speed of light

In September 2011, an international group of scientists has made an astonishing claim – they have detected particles that seemed to travel faster than the speed of light. It was a claim that contradicted more than a hundred years of scientific orthodoxy. Suddenly there was talk of all kinds of bizarre concepts, from time travel to parallel universes.

So what is going on? Has Einstein‘s famous theory of relativity finally met its match? Will we one day … Ler mais

Horizon: How Big is the Universe?

This episode follows the cosmologists who are creating the most ambitious map in history - a map of everything in existence

It is one of the most baffling questions that scientists can ask: how big is the universe that we live in?

Horizon follows the cosmologists who are creating the most ambitious map in history, a map of everything in existence. And it is stranger than anyone had imagined, a universe without end that stretches far beyond what the eye can ever see.

And, if the latest research proves true, our universe may just be the start of something even bigger. … Ler mais

The Path to Nuclear Fission: The Story of Lise Meitner and Otto Hahn

A portrait of the life and times of two remarkable scientists and their extraordinary collaboration

The story of two close friends who discovered nuclear fission is told in great detail within the context of both World Wars. This video is as much about role of scientists in political events, social responsibility, and discrimination against women and Jews, as it is about the science, though the science is clearly explained. Archival film footage and photographs are extensively and effectively used throughout the production.
Most fascinating are the contrasting life choices made by these two scientists. They … Ler mais

The Ultimate Formula

For over a century, physicists have searched for a blueprint of the universe in the form of a single mathematical formula

The great mysteries of the universe have long fascinated humankind, and for physicists, the answer to everything lies in the “ultimate formula”. Throughout history, scientists like Newton and Einstein have believed that all natural phenomena can be explained by a single formula. And now, with the discovery of the Higgs boson, the ultimate formula is almost within our grasp. Exploring the frontier of human knowledge, we look at the story of the brilliant physicists and their indefatigable efforts to … Ler mais

Living in a Parallel Universe

Parallel universes have haunted science fiction for decades, but a surprising number of top scientists believe they are real

In many cases, reality is weirder than any science fiction fantasy. Parallel universes have haunted novels and movies for decades and at the beginning of the 21st century in the labs and minds of theoretical physicists, parallel universes are being seriously explored as never before. Long since scientists believe that there is far more to the cosmos than we can currently detect. Particularly, quantum mechanics has made it very hard for them to ignore the idea of parallel universes.

Horizon: Parallel Universes

The documentary has to do with parallel universes, string theory, M theory, supergravity, and other theoretical physics concepts

Everything you’re about to read here seems impossible and insane, beyond science fiction. Yet it’s all true.

Scientists now believe there may really be a parallel universe – in fact, there may be an infinite number of parallel universes, and we just happen to live in one of them. These other universes contain space, time and strange forms of exotic matter. Some of them may even contain you, in a slightly different form. Astonishingly, scientists believe that these parallel universes … Ler mais
