Horizon looks at dark energy - the mysterious force that is unexpectedly causing the universe's expansion to speed up
The effects of dark energy were discovered in 1998, but physicists still don’t know what it is. Worse, its very existence calls into question Albert Einstein‘s general theory of relativity – the cornerstone of modern physics.
The hunt for the identity of dark energy is on. Experiments on earth and in space generate data that might provide a clue, but there are also hopes that another Einstein might emerge – someone who can write a new theory explaining the … Ler mais
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
A documentary produced in 1979 to celebrate the centenary of the birth of Albert Einstein
Based on Nigel Calder’s book Einstein’s Universe, this fascinating and rare film going by the same title has been re-mastered and digitally enhanced to bring Einstein fans a priceless experience. Narrated by the charismatic Peter Ustinov and hosted by Nigel Calder, the film was first broadcast on the centenary of Albert Einstein’s Birth; March 14th, 1979. Ustinov takes the viewer on a wonderful experience through the McDonald Observatory at the University of Texas-Austin where he is thoroughly enlightened … Ler mais

The story of the most elegant and powerful theory in science, Albert Einstein's general relativity. It takes us inside the head of Einstein to witness how his idea evolved.
The story of the most elegant and powerful theory in science – Albert Einstein’s general relativity.
When Einstein presented his formidable theory in November 1915, it turned our understanding of gravity, space and time completely on its head. Over the last 100 years, general relativity has enabled us to trace the origins of the universe to the Big Bang and to appreciate the enormous power of black holes.
To mark the 100th anniversary of general relativity, this film … Ler mais
A descoberta da Teoria da Relatividade Geral
O documentário, intitulado Einstein – Sinfonia Inacabada (Einstein’s Unfinished Symphony) assinala o ano em que se comemoraram os 50 anos da morte do cientista e o centenário da publicação da Teoria da Relatividade. As Nações Unidas (ONU) associaram-se às celebrações dessas duas efemérides, estabelecendo 2005 como o Ano Internacional da Física.
O filme documental esclarece sobre a descoberta da Teoria da Relatividade Geral e acompanha também, ficcionalmente, os últimos dois dias de vida do cientista, enquanto lutava por … Ler mais
A história da assombrosa vida pessoal e profissional de Albert Einstein
Este programa é um especial de duas horas no qual será narrada a história da assombrosa vida pessoal e profissional de Albert Einstein de uma forma única: enquadrada entre os dois eclipses solares que ocorreram em 1914 e em 1919.
Embora o trabalho mais importante de Albert Einstein tenha sido realizado em 1905, quando concebeu as suas teorias da relatividade e da relatividade especial, teriam que passar catorze anos antes dos seus princípios nada convencionais poderem ser demonstrados.
Até então, … Ler mais
Onze dimensões, universos paralelos, e um mundo feito de cordas. Não é ficção científica, é a teoria das cordas.
O Universo Elegante: Supercordas, Dimensões Ocultas e a Busca pela Teoria Final (título original: The Elegant Universe: Superstrings, Hidden Dimensions and the Quest for the Ultimate Theory) (ISBN 0-375-70811-1) é um livro do físico Brian Greene, publicado em 1999, que introduz à teoria das cordas fornecendo uma explicação em linguagem simples e não-técnica dessa teoria, bem como suas inconsistências.
Começando com uma breve consideração da física clássica, que se concentra nos grandes conflitos da física dessa época, Greene … Ler mais
