Our knowledge of the universe comes from looking at it in various ways — different wavelengths of light, neutrinos, cosmic rays, and hopefully some day gravitational radiation. But how do we know that we are seeing everything there is? How could we determine whether there were substances in the universe not directly visible in our telescopes?
Is the universe bursting at the seams? Or is nature somehow fooling us?
The astronomers whose data revealed this accelerating universe have been awarded the Nobel Prize for Physics.
And yet, since 1998, when the discovery was first announced, scientists have struggled to come to grips with a mysterious presence that now appears to control the future of the cosmos: dark energy.
What is exactly universe? The universe is commonly defined as the totality of everything that exists,including all physical matter and energy, the planets, stars, galaxies, and the contents of intergalactic space,although this usage may differ with the context. The term universe may be used in slightly different contextual senses, denoting such concepts as the cosmos, the world, or nature.
Observations of earlier stages in the development of the universe, which can be seen at great distances, suggest that the universe has been governed by the same physical laws and constants throughout most of its extent and history.Our universe, the galaxies, solar system, planet Earth — land, sea, air, life — where did they come from? Astronomer Edwin Hubble believes our universe once was very tiny. Take a journey through space and time to discover how the universe was born.
Explores one of the deepest mysteries about the origin of our universe. According to standard theory, the early moments of the universe were marked by the explosive contact between subatomic particles of opposite charge. Featuring short interviews with Masaki Hori, Tokyo University and Jeffrey Hangst, Aarhus University.
Scientists are now focusing their most powerful technologies on an effort to figure out exactly what happened. Our understanding of cosmic history hangs on the question: how did matter as we know it survive? And what happened to its birth twin, its opposite, a mysterious substance known as antimatter?
A crew of astronauts is making its way to a launch pad at the Kennedy Space Center in Florida. Little noticed in the publicity surrounding the close of this storied program is the cargo bolted into Endeavor’s hold. It’s a science instrument that some hope will become one of the most important scientific contributions of human space flight.
With the help of a hammer-wielding scientist, Jennifer Aniston and a general anaesthetic, Professor Marcus du Sautoy goes in search of answers to one of science’s greatest mysteries: how do we know who we are? While the thoughts that make us feel as though we know ourselves are easy to experience, they are notoriously difficult to explain. So, in order to find out where they come from, Marcus subjects himself to a series of probing experiments.
Very interesting documentary describing the evolution of everything.
This film is a part of TROM documentary. In this episode you will see Reality of everything. From the Big Bang until today.
Evolution of Organisms.
Evolution in organisms occurs through changes in heritable traits – particular characteristics of an organism. In humans, for example, eye color is an inherited characteristic and an individual might inherit the “brown-eye trait” from one of their parents. Inherited traits are controlled by genes and the complete set of genes within an organism’s genome is called its genotype.
The TROM documentary is trying to present, in a simplistic way, the world in which we, human beings, live. The world discovered so far, not some idea or personal choice. Moreover we tried to present alternative solutions to current problems and took into account the future, which promises to be more than interesting.
An informative documentary, perhaps shocking and disturbing to many, depending on how you digest the information.

Meet the scientific prophets who claim we are on the verge of creating a new type of human – a human v2.0. It’s predicted that by 2029 computer intelligence will equal the power of the human brain. Some believe this will revolutionise humanity – we will be able to download our minds to computers extending our lives indefinitely. Others fear this will lead to oblivion by giving rise to destructive ultra intelligent machines. One thing they all agree on is that the coming of this moment – and whatever it brings – is inevitable.
“Where did we come from?” with host Neil DeGrasse Tyson explores the origin of our solar system and the start of life itself, how head lice figure in human evolution, and more. Journey back in time to the birth of our solar system to examine whether the key to our planet’s existence might have been the explosive shock wave of an ancient supernova. Meet a chemist who has yielded a new kind of “recipe” for natural processes to assemble and create the building blocks of life. And see how the head louse, a creepy critter that’s been sucking our blood for millions of years, is offering clues about our evolution. Finally, meet neuroscientist André Fenton, who is looking into erasing painful memories with an injection.
Comparing the reality of space travel to science fiction, revealing the truth behind common myths and misconceptions about the universe and exploring the mysteries that remain unsolved. Narrated by Erik Thompson
Why are you more likely to have a heart attack at eight o’clock in the morning or crash your car on the motorway at two o’clock in the afternoon? Can taking your medication at the right time of day really save your life? And have you ever wondered why teenagers will not get out of bed in the morning?
The answers to these questions lie in the secret world of the biological clock.
