How the Universe Works - National Geographic The Universe part 4 - Space Discovery Documentary

Our Solar System, and all other star systems, form from a collapsing nebula. Often called stellar nurseries, nebulae are the birthplace of stars. They are made up of mostly hydrogen but also contain other matter like gases, dust, ice and rock. The gravity of the nebula pulls this matter into the centre, and the nebula experiences a gravitational collapse. If the compression raises the core temperature enough to reach thermonuclear fusion, the centre mass generates a protostar. This process takes about 10 million years.

Approximately 4.5 billion years ago, gravity pulled a cloud of dust and gas together to form our solar system. While scientists aren't certain of the exact nature of the process, observations of young stellar systems combined with computer simulations have allowed them to develop three models of what could have happened so many years ago.

How The Universe Works? Journey Through The Universe - FullHD Documentary

The Universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. While the spatial size of the entire Universe is unknown, it is possible to measure the size of the observable universe, which is currently estimated to be 93 billion light years in diameter. In various multiverse hypotheses, a universe is one of many causally disconnected constituent parts of a larger multiverse, which itself comprises all of space and time and its contents.

The earliest scientific models of the Universe were developed by ancient Greek and Indian philosophers and were geocentric, placing Earth at the center of the Universe. Over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the center of the Solar System. In developing the law of universal gravitation, Isaac Newton built upon Copernicus' work as well as observations by Tycho Brahe and Johannes Kepler's laws of planetary motion.

Further observational improvements led to the realization that the Sun is one of hundreds of billions of stars in the Milky Way, which is one of at least hundreds of billions of galaxies in the Universe. Many of the stars in our galaxy have planets. At the largest scale galaxies are distributed uniformly and the same in all directions, meaning that the Universe has neither an edge nor a center. At smaller scales, galaxies are distributed in clusters and superclusters which form immense filaments and voids in space, creating a vast foam-like structure. Discoveries in the early 20th century have suggested that the Universe had a beginning and that space has been expanding since then, and is currently still expanding at an increasing rate.

The Big Bang theory is the prevailing cosmological description of the development of the Universe. Under this theory, space and time emerged together 13.799±0.021 billion years ago and the energy and matter initially present have become less dense as the Universe expanded. After an initial accelerated expansion called the inflationary epoch at around 10−32 seconds, and the separation of the four known fundamental forces, the Universe gradually cooled and continued to expand, allowing the first subatomic particles and simple atoms to form. Dark matter gradually gathered forming a foam-like structure of filaments and voids under the influence of gravity. Giant clouds of hydrogen and helium were gradually drawn to the places where dark matter was most dense, forming the first galaxies, stars, and everything else seen today. It is possible to see objects that are now further away than 13.799 billion light-years because space itself has expanded, and it is still expanding today. This means that objects which are now up to 46.5 billion light-years away can still be seen in their distant past, because in the past when their light was emitted, they were much closer to the Earth.

From studying the movement of galaxies, it has been discovered that the universe contains much more matter than is accounted for by visible objects; stars, galaxies, nebulas and interstellar gas. This unseen matter is known as dark matter[18] (dark means that there is a wide range of strong indirect evidence that it exists, but we have not yet detected it directly). The ΛCDM model is the most widely accepted model of our universe. It suggests that about 69.2%±1.2% [2015] of the mass and energy in the universe is a cosmological constant (or, in extensions to ΛCDM, other forms of dark energy such as a scalar field) which is responsible for the current expansion of space, and about 25.8%±1.1% [2015] is dark matter. Ordinary (baryonic) matter is therefore only 4.9% [2015] of the physical universe. Stars, planets, and visible gas clouds only form about 6% of ordinary matter, or about 0.3% of the entire universe.

There are many competing hypotheses about the ultimate fate of the universe and about what, if anything, preceded the Big Bang, while other physicists and philosophers refuse to speculate, doubting that information about prior states will ever be accessible. Some physicists have suggested various multiverse hypotheses, in which our universe might be one among many universes that likewise exist.

How the Universe Works - Black holes - Space Discovery Documentary

The idea of an object in space so massive and dense that light could not escape it has been around for centuries. Most famously, black holes were predicted by Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core. If the core's mass is more than about three times the mass of the Sun, the equations showed, the force of gravity overwhelms all other forces and produces a black hole.

Scientists can't directly observe black holes with telescopes that detect x-rays, light, or other forms of electromagnetic radiation. We can, however, infer the presence of black holes and study them by detecting their effect on other matter nearby. If a black hole passes through a cloud of interstellar matter, for example, it will draw matter inward in a process known as accretion. A similar process can occur if a normal star passes close to a black hole. In this case, the black hole can tear the star apart as it pulls it toward itself. As the attracted matter accelerates and heats up, it emits x-rays that radiate into space. Recent discoveries offer some tantalizing evidence that black holes have a dramatic influence on the neighborhoods around them - emitting powerful gamma ray bursts, devouring nearby stars, and spurring the growth of new stars in some areas while stalling it in others.

Living Universe | Journey To Another Stars - Documentary 4K

The Earth is Not Alone:
LIVING UNIVERSE is an interstellar adventure that seeks to answer the most profound question of all: are we alone? Based on the latest scientific knowledge, we will take a journey to a planet beyond our solar system in search of life.

We ask the world's leading space scientists what we might find if we travel to a neighboring star system. Recent breakthroughs have proven that every star we see in the sky is orbited by at least one planet, many similar to our own Earth. How do we get to these exoplanets? Once there, what will we find? And what will it mean for humanity when we discover we are not alone?

Our speculative journey through space is set a hundred years in the future - when we have the technology to journey well beyond our solar system. On this first expedition, our star ship Aurora will be piloted not by astronauts, but by the artificial intelligence (A.I.) we call Artemis. We imagine how Artemis travels through space, on its 25-year journey, at one fifth of the speed of light. Its objective is Minerva B, a planet much like our own, with an atmosphere, temperature and liquid water that appears a likely candidate to contain life.

With spectacular special effects we will reach and explore a new planet as we seek to answer the most profound question of all: are we alone in the universe? Our guides on this journey are narrator Dr Karl Kruszelnicki and as the voice of our AI, Artemis, real-life astrophysicist, Professor Tamara Davis.

Inspired and informed by our rapidly developing knowledge of far-off worlds, our best scientists - including NASA engineers, astrophysicists and astronomers - we will discover that this amazing journey is not only possible, it is inevitable. To venture into distant space is our destiny.

LIVING UNIVERSE captures a pivotal moment in the human story. A film full of insight and inspiration certain to thrill anyone who dreams of distant worlds, or have ever wondered why are we here?

Have you ever wondered that someone like you, sitting less than a mile away, in some other universe, exists? The possibility in itself seems frightening as well as astonishing.

From breaking news and intriguing historical documentaries to conspiracy theories, classified NASA files and UFO's. We provide you with material that the government doesn't want you to see. The Insomnia team comes up with a promise. To keep up with the same, the team now brings to us a documentary that aims to change your perspective Of another existence, of another possibility, as today, the scientists now believe there may really be the presence of a parallel universe - and in fact, also believe that there may be an infinite number of parallel universes, and where we live today just happens to be only one of them and many of these other parallel universes come with different laws of physics as well.

These other universes that we are talking about not only contain space, time and strange forms of exotic matter but to surprise you, Some of them may even contain you, only maybe in a slightly different form. The thought itself is quite intriguing and scary on the same hand. The basis of this theory is as we know it the idea that parallel universes are constantly spinning off from reality that we humans know of. Though generally ignored at the time, that theory has gone on to become not just a popular topic of study among respected physicists, but the inspiration for such popular films, television shows, and books as Star Trek and The Golden Compass. according to the sources.

The video soon progresses into the Wilkinson Microwave Anisotropy Probe (WMAP), that is now changing everything, as some say that the remarkable images reveal the true shape of the universe through baby pictures of the same from the time when it was 4 hundred thousand years old, looking so back in time, when there wasn't even the formation of galaxies yet. The WMAP is catching the very first signs of creation as it is officially tagged with measuring radiation that is left over from Big Bang. And now scientists have devised an experiment to find the overall true shape of the universe. The WMAP hence shows that the universe is flat. From here arises the possibility of more mind boggling parallel universe that are of the level-2 type and is made up of giant cosmic soap bubbles that float in hyperspace. Each of these bubbles within it has a whole universe. Now, the question that arises is that - Do we all live in a giant cosmic bubble?
