The current best fit model is a flat ΛCDM Big Bang model where the expansion of the Universe is accelerating, and the age of the Universe is 13.7 billion years. Back to top. What is the evidence for the Big Bang? The evidence for the Big Bang comes from many pieces of observational data that are consistent with the Big Bang. The darkness of the night sky - Olbers' paradox. Why do we think that the expansion of the Universe is accelerating? The evidence for an accelerating expansion comes from observations of the brightness of distant supernovae. What is quintessence? Quintessence, or the fifth essence, is a fifth element beyond the standard earth, air, fire and water of ancient chemistry. If the Universe is only 14 billion years old, why isn't the most distant object we can see 7 billion light years away? What is the redshift?
Cosmology SDSS-III Future - Science & Environment - Drake equation: How many alien civilizations exist? Are we alone? It is a question that has occupied mankind for centuries. Today, we live in an age of exploration, where robots on Mars and planet-hunting telescopes are beginning to allow us to edge closer to an answer. While we wait to establish contact, one technique we can use back on Earth is an equation that American astronomer Frank Drake formulated in the 1960s to calculate the number of detectable extraterrestrial civilizations may exist in the Milky Way galaxy. It is not a rigorous equation, offering a wide range of possible answers. Until ground-based observations, space telescopes and planet-roving robots uncover any tell-tale signs of life, what better way to speculate on how many intelligent alien civilizations may exist than to explore the universe with our interactive version of the equation.
The Massey Experience Welcome to The Massey Experience, an online exploration of the ideas, themes, theories and characters that form Neil Turok's 2012 Massey Lectures The Universe Within: From Quantum to Cosmos. The Massey Experience is an immersive, evolving companion to Neil's Massey Lectures which aired on CBC Radio's IDEAS in November 2012. The story is a journey from quantum to cosmos: where we've come from, where we're going and what we've learned along the way. Neil argues that we're on the cusp of yet another major transformation: a coming quantum revolution that will supplant our current digital age. It's the story of science and technology, but it is also the story of who we are: amazing creative humans. You can also explore the Massey Lectures by purchasing The Universe Within from House of Anansi Press. About Neil Turok Neil Turok is one of the world's leading physicists, and a renowned educational innovator. Turok was awarded the James Clerk Maxwell medal of the U.K.
