Where does a cup of coffee come from? In this film, it’s not Starbucks, it’s stars busting. We go right back to the beginning of time to show where the ingredients in your cup of coffee were born.

The main ingredient is hydrogen; it makes up most of the water in your cup. And that formed in the big bang. How it got from there, into your cappuccino is one of the most dramatic stories in science. It has taken thousands of scientists to track its trail. We follow it through stars and galaxies, exploding supernovae, and giant clouds of gas to show just how it reached your cup.

But that isn’t the end of the story. For where it goes in the future, depends on the fate of the universe. Will it carry on expanding for ever, or tear itself apart?

Every other Wednesday we present a new video, so join us to see the truth laid bare...

How did the Earth evolve to support life.

Our planet now supports a huge diversity of living creatures requiring very special conditions, but what was the series of events that brought this unique set of conditions together? What did it take to make a world that would support human life? Naked Science takes an imaginary ‘human’ time traveller on a journey back to the moment of formation of our solar system. We meet the scientists who are carrying out their own detective work, uncovering the clues around the world today into what our planet was like 4 and a half billion years ago.

Our journey begins with the astonishing story of how a giant cloud of interstellar dust and gas collapsed to form the sun and planets. We discover that the intense heat of the early Earth created a molten iron core. This generated a magnetic shield around our planet that protects us, to this day, from the sun’s deadliest particles.

Many of the features we take for granted on our living planet were forged in the most violent event in our planet’s history. Early in its life, the Earth collided with another planet. Planetary Scientist Robin Canup has modelled the impact using supercomputers. She reveals that the resulting fireball was so energetic it melted the Earth and created the moon. This dramatic impact gave us our tides and seasons.

We wouldn’t have life today without water. But where our water came from is a mystery that has long puzzled scientists. At a NASA research laboratory, Michael Zolensky studies a recently discovered meteorite that supports the view that water came from space.

For the first half of its history the Earth had an atmosphere of methane and carbon dioxide we would find impossible to breathe. One clue as to how the earth acquired its oxygen can be found in Australia. Shark Bay in Western Australia is home to strange bacterial mounds called stromatolites. The bacteria in these objects are pumping out oxygen. A few hundred miles away geologist Martin Van Kranendonk shows us a fossil stromatolite, the world’s oldest fossil. The evidence suggests that these strange objects are responsible for creating the air we breathe.

Naked Science - Moon Mysteries

Subscribe to Naked Science -

Every other Wednesday we present a new video, so join us to see the truth laid bare...

The moon is far more than just a beautiful object in the night sky.

Ever since its creation 4.5 billion years ago the moon has been edging away from Earth into space. Throughout its journey, it has influenced our planet in different ways. But one things clear, without it life would never have emerged on Earth.

4.5 billion years ago the moon forms when another planet slams into the early Earth. The impact knocks our planet “off-balance” onto an axis of 23 degrees, which we still rotate around today. This is what gives us our seasons. Without it we would have no summers, springs, winters or falls.

4 billion years ago the solar system endures the most violent meteorite bombardment in its history, the Lunar Cataclysm. The Earth, being 50 times bigger than the moon, exerts a massive gravitational pull on incoming space debris. Because the moon is still so close to Earth it too gets hit. 99% of all craters on the lunar surface visible today are a result of this bombardment.

3 billion years ago the Earth has water and oceans. Because the moon is far closer its gravitational pull is far stronger on the Earth. The tides it creates are thousands of feet high and smash hundreds of miles inland every day. Scientists believe that these tides feed the Primordial Soup with the minerals required to start life. Without them only the most basic microbes would be on Earth today.

Today the moon has the same gravitational pull as a mosquito landing on your head, yet some people still believe it can influence our planet in bizarre ways.

The San Francisco Police Department tell us how crime appears to soar during a full moon. But the scientific data suggests otherwise, studies show no correlation between the Full Moon and violence. Naked Science investigates.

Scientific research into the moon is allowing some scientists to predict when natural disasters will strike. Some researchers believe that when the sun and moon align and pull together on the Earth they can trigger both earthquakes and volcanic eruptions.

In the future the moon will move so far from Earth that it will affect the fine balance of our planet, sending our climate tumbling out of control.

The History of Earth - How Our Planet Formed - Full Documentary HD

In the very beginning of earth's history, this planet was a giant, red hot, roiling, boiling sea of molten rock - a magma ocean. The heat had been generated by the repeated high speed collisions of much smaller bodies of space rocks that continually clumped together as they collided to form this planet. As the collisions tapered off the earth began to cool, forming a thin crust on its surface. As the cooling continued, water vapor began to escape and condense in the earth's early atmosphere. Clouds formed and storms raged, raining more and more water down on the primitive earth, cooling the surface further until it was flooded with water, forming the seas.

It is theorized that the true age of the earth is about 4.6 billion years old, formed at about the same time as the rest of our solar system. The oldest rocks geologists have been able to find are 3.9 billion years old. Using radiometric dating methods to determine the age of rocks means scientists have to rely on when the rock was initially formed (as in - when its internal minerals first cooled). In the infancy of our home planet the entire earth was molten rock - a magma ocean.

Since we can only measure as far back in time as we had solid rock on this planet, we are limited in how we can measure the real age of the earth. Due to the forces of plate tectonics, our planet is also a very dynamic one; new mountains forming, old ones wearing down, volcanoes melting and reshaping new crust. The continual changing and reshaping of the earth's surface that involves the melting down and reconstructing of old rock has pretty much eliminated most of the original rocks that came with earth when it was newly formed. So the age is a theoretical age.

When Did Life on Earth Begin?

Scientists are still trying to unravel one of the greatest mysteries of earth: When did life first appear and how did it happen? It is estimated that the first life forms on earth were primitive, one-celled creatures that appeared about 3 billion years ago. That's pretty much all there was for about the next two billion years. Then suddenly those single celled organisms began to evolve into multicellular organisms. Then an unprecedented profusion of life in incredibly complex forms began to fill the oceans. Some crawled from the seas and took residence on land, perhaps to escape predators in the ocean. A cascading chain of new and increasingly differentiated forms of life appeared all over the planet, only to be virtually annihilated by an unexplained mass extinction. It would be the first of several mass extinctions in Earth's history.

Scientists have been looking increasingly to space to explain these mass extinctions that have been happening almost like clockwork since the beginning of living time. Perhaps we've been getting periodically belted by more space rocks (ie. asteroids), or the collision of neutron stars happening too close for comfort? Each time a mass extinction occurred, life found a way to come back from the brink. Life has tenaciously clung to this small blue planet for the last three billion years. Scientists are finding new cues as to how life first began on earth in some really interesting places - the deep ocean.

Universe: Beyond the Millennium - Creation

Universe: Beyond the Millennium is a television series observing astronomical phenomena, research, and theories on the universe and its origins.

Narrated by John Hurt.

The documentary premiered in 1999 and presents an overview of the universe as humans understood it at that time, and how we think it will evolve in the next millennium. Using 3D computer generated graphics, the series features animated sequences that offer insight into the Big Bang theory and the anatomy of the sun.

Creation, for years scientists have speculated about the beginning of the universe. Some astronomers support the Big Bang theory while others purport the Steady State theory. Which one is correct? Telescopes that tune into natural heat radiation coming from space are helping scientists find answers to these and other questions.

One day our universe will cool and die, our only escape maybe to risk a flight into a different universe. Perhaps the greatest question facing the human race is to discover where we came from, and find out what is our ultimate fate. Every culture, every age, has asked that question and tried answering it.

Space Science Documentary - Naked Science - Alien Contact

Just for a moment, imagine a universe awash with life, where we humans are not the only intelligent beings around. What might these alien races look like? Could we communicate with them, or even recognise them as intelligent? And what would they make of our violent and dangerous species?

Might they take one look, and decide not to bother with such primitive beings? A planetary nursery filled with spiteful, galactic infants. On the other hand, in our imaginary scenario, they may enrich us with scientific knowledge beyond our imagination. Or could an encounter with aliens have a more destructive outcome? It could be a bad day for human kind.

But relax, it's just make believe, it could never happen, could it? A mysterious crash in Roswell, New Mexico during the 1940s convinced many that our planet is being visited by space aliens. Crop circles in Britain have only added fuel to the fire. Few scientists doubt that life indeed exists elsewhere, but some believe we're more likely to make contact via radio waves. Join the search for extra-terrestrials and hear from scientists who think we are on the verge of making contact.

The Origin of The Universe - Space Documentary

Groundbreaking physicist Stephen Hawking left us one last shimmering piece of brilliance before he died: his final paper, detailing his last theory on the origin of the Universe, co-authored with Thomas Hertog from KU Leuven.

The paper, published in the Journal of High Energy Physics in May, puts forward that the Universe is far less complex than current multiverse theories suggest.

It's based around a concept called eternal inflation, first introduced in 1979 and published in 1981.

After the Big Bang, the Universe experienced a period of exponential inflation. Then it slowed down, and the energy converted into matter and radiation.

However, according to the theory of eternal inflation, some bubbles of space stopped inflating or slowed on a stopping trajectory, creating a small fractal dead-end of static space.

Meanwhile, in other bubbles of space, because of quantum effects, inflation never stops - leading to an infinite number of multiverses.

Everything we see in our observable Universe, according to this theory, is contained in just one of these bubbles - in which inflation has stopped, allowing for the formation of stars and galaxies.

The usual theory of eternal inflation predicts that globally our universe is like an infinite fractal, with a mosaic of different pocket universes, separated by an inflating ocean, Hawking explained.

The local laws of physics and chemistry can differ from one pocket universe to another, which together would form a multiverse. But I have never been a fan of the multiverse. If the scale of different universes in the multiverse is large or infinite the theory can't be tested.

Even one of the original architects of the eternal inflation model has disavowed it in recent years.

Paul Steinhardt, physicist at Princeton University, has gone on record saying that the theory took the problem it was meant to solve - to make the Universe, well, universally consistent with our observations - and just shifted it onto a new model.

Hawking and Hertog are now saying that the eternal inflation model is wrong. This is because Einstein's theory of general relativity breaks down on quantum scales.

The problem with the usual account of eternal inflation is that it assumes an existing background universe that evolves according to Einstein's theory of general relativity and treats the quantum effects as small fluctuations around this, Hertog explained.

However, the dynamics of eternal inflation wipes out the separation between classical and quantum physics. As a consequence, Einstein's theory breaks down in eternal inflation.

Hawking's last theory is based on string theory, one of the frameworks that attempts to reconcile general relativity with quantum theory by replacing the point-like particles in particle physics with tiny, vibrating one-dimensional strings.

In string theory, the holographic principle proposes that a volume of space can be described on a lower-dimensional boundary; so the universe is like a hologram, in which physical reality in 3D spaces can be mathematically reduced to 2D projections on their surfaces.

The researchers developed a variation of the holographic principle that projects the time dimension in eternal inflation, which allowed them to describe the concept without having to rely on general relativity.

This then allowed them to mathematically reduce eternal inflation to a timeless state on a spatial surface at the beginning of the Universe - a hologram of eternal inflation.

When we trace the evolution of our universe backwards in time, at some point we arrive at the threshold of eternal inflation, where our familiar notion of time ceases to have any meaning, said Hertog.

In 1983, Hawking and another researcher, physicist James Hartle, proposed what is known as the 'no boundary theory' or the 'Hartle-Hawking state'. They proposed that, prior to the Big Bang, there was space, but no time. So the Universe, when it began, expanded from a single point, but doesn't have a boundary.

According to the new theory, the early Universe did have a boundary, and that's allowed Hawking and Hertog to derive more reliable predictions about the structure of the Universe.

We predict that our universe, on the largest scales, is reasonably smooth and globally finite. So it is not a fractal structure, Hawking said.

It's a result that doesn't disprove multiverses, but reduces them to a much smaller range - which means that multiverse theory may be easier to test in the future, if the work can be replicated and confirmed by other physicists.

Hertog plans to test it by looking for gravitational waves that could have been generated by eternal inflation.

These waves are too large to be detected by LIGO, but future gravitational wave interferometers such as space-based LISA, and future studies of the cosmic microwave background, may reveal them.
