BBC-Doku: Wonders of the Universe – Episode 4 – “Messengers”

Hier nun wie angekündigt die letzte Episode der großartigen BBC Doku-Reihe “Wonders of the Universe” mit Brian Cox, der uns im großen Finale auf die lange Reise des Lichtes mitnimmt, dem Leuchten der Geburt unseres Universums auf die Spur geht und den Quantenfluktuationen die unser Leben ermöglicht haben, sowie dem Sinnesorgan das uns all diese Erkenntnisse erst ermöglicht hat.

In the last episode of Professor Brian Cox’s epic journey across the universe, he travels from the fossils of the Burgess Shale to the sands of the oldest desert in the world to show how light holds the key to our understanding of the whole universe, including our own deepest origins.

To understand how light holds the key to the story of the universe, you first have to understand its peculiar properties. Brian considers how the properties of light that lend colour to desert sands and the spectrum of a rainbow can lead to profound insights into the history and evolution of our universe.

Finally, with some of the world’s most fascinating fossils in hand, Brian considers how but for an apparently obscure moment in the early evolutionary history of life, all the secrets of light may have remained hidden. Because although the universe is bathed in light that carries extraordinary amounts of information about where we come from, it would have remained invisible without a crucial evolutionary development that allowed us to see. Only because of that development can we now observe, capture and contemplate the incredible wonders of the universe that we inhabit.

BBC-Doku: Wonders of the Universe – Episode 3 – “Falling”

Gestern lief die dritte Episode der fantastischen Doku-Reihe “Wonders of the Universe” mit Brian Cox, die heute jemand ins Netz geladen und zum Ende dieser Folge einen wahrhaft Sagan’schen Moment erlebt, wenn Prof. Cox darüber spricht wie Gravitation und die Einstein’sche Relativitästheorie die wahre Schönheit der Wissenschaft offenbaren.

In the third episode, Professor Brian Cox takes on the story of the force that sculpts the entire universe – gravity.

Gravity seems so familiar, and yet it is one of the strangest and most surprising forces in the universe. Starting with a zero gravity flight, Brian experiences the feeling of total weightlessness, and considers how much of an effect gravity has had on the world around us.

But gravity also acts over much greater distances. It is the great orchestrator of the cosmos. It dictates our orbit around the sun, our relationship with the other planets in our solar system, and even the way in which our solar system orbits our galaxy.

Yet the paradox of gravity is that it is actually a relatively weak force. Brian takes a face distorting trip in a centrifuge to explain how it is that gravity achieves its great power, before looking at the role it plays in one of the most extraordinary phenomena in the universe – a neutron star. Although it is just a few kilometres across, it is so dense that its gravity is 100, 000 million times as strong as on Earth.

Over the centuries our quest to understand gravity has allowed us to understand some of the true wonders of the universe, and Brian reveals that it is scientists’ continuing search for answers that inspires his own sense of wonder.

BBC-Doku: Wonders of the Universe – Episode 2 – “Stardust”

Nach etwas längerem Warten ist endlich die zweite Episode der BBC-Dokureihe Wonders of the Universe im Netz aufgetaucht. Dieses mal berichtet uns Brian Cox von der Entstehung der Elemente, den verschiedenen Lebenszyklen von Sonnen, wie es wohl aussehen könnte, wenn Beteigeuze demnächst als Supernova explodiert und warum wir aus den Überresten von toten Sternen bestehen.

In the second stop in his exploration of the wonders of the universe, Professor Brian Cox goes in search of humanity’s very essence to answer the biggest questions of all: what are we? And where do we come from? This film is the story of matter – the stuff of which we are all made.

Brian reveals how our origins are entwined with the life cycle of the stars. But he begins his journey here on Earth. In Nepal, he observes a Hindu cremation. Hindu philosophy is based on an eternal cycle of creation and destruction, where the physical elements of the body are recycled on to the next stage. Brian draws a parallel with the life cycle of the stars that led to our own creation.

Next, he explains how the Earth’s resources have been recycled through the ages. How every atom that makes up everything we see, was at some time a part of something else. Our world is made up of just 92 elements, and these same 92 elements are found throughout the entire universe. We are part of the universe because we are made of the same stuff as the universe.

Eine tolle Folge, die zumindest bei mir, wieder jede Menge Lust auf Chemie und Sternebeobachten gemacht hat. Seht es euch an solange es noch online ist. Hier noch Episode 1, welche ich vor einer Woche verbloggt hatte.

BBC-Doku: Wonders of the Universe – Episode 1 – “Destiny”

Gestern feierte die erste Episode “Destiny” der BBC-Doku Wonders of the Universe über die Zeit mit Ausnahmephysiker Brian Cox noch Premiere und heute hat sie schon jemand bei Youtube hochgeladen. Hier mal die Synopsis der Episode:

Having explored the wonders of the solar system, Professor Brian Cox steps boldly on to an even bigger stage – the universe.

Who are we? Where do we come from? For thousands of years humanity has turned to religion and myth for answers to these enduring questions. But in this series, Brian presents a different set of answers – answers provided by science.

In this episode, Brian seeks to understand the nature of time and its role in creating both the universe and ourselves. From an extraordinary calendar built into the landscape of Peru to the beaches of Costa Rica, Brian explores the cycles of time which define our experience of life on Earth. But even the most epic cycles of life can’t begin to compare to the vast expanse of cosmic time.

For instance, just as the Earth orbits the Sun, the solar system orbits the entire Milky Way galaxy. This orbit takes a staggering 250 million years to complete.

Ultimately, Brian discovers that time is not characterised by repetition but by irreversible change. From the relentless march of a glacier, to the decay of an old mining town, the ravaging effects of time are all around us. The vast universe is subject to these same laws of change. As we look out to the cosmos, we can see the story of its evolution unfold, from the death of the first stars to the birth of the youngest. This journey from birth to death will ultimately lead to the destruction not just of our planet, but also the entire universe, and with it the end of time itself.

Yet without this inevitable destruction, the universe would be without what is perhaps the greatest wonder of all; the brief moment in time in which life can exist.

Doku-Trailer: Wonders of the Universe

Oh stark! Die BBC hat sich wieder Brian Cox ins Boot geholt um mit ihm zusammen nach Wonders of the Solar System eine weitere Serie über unser Universum und seine Mysterien zu drehen. Sendestart von Wonders of the Universe ist heute abend auf BBC. Mal sehen, vielleicht haben wir ja Glück und die Folgen tauchen wieder mit etwas Verzögerung im Netz auf. Der Trailer sieht schon mal exzellent aus.
