In 1998 The Accelerating expansion of the Universe was discovered by two competing groups of scientists called the Supernova Cosmology Project and the High-Z Supernova Search Team that were led by Saul Perlmutter, Adam Reiss, and Brian Schmidt. And In 2011 they were awarded noble prizes in physics for their discovery of the accelerating expansion of the Universe. They did so by applying new technologies like computers and digital cameras to study and measure the spectrum and brightness of the light
Joel Garreau believes that we are moving towards a post-human future where humanity will no longer exist as we know it to. Just as Paul Virilio states that we are becoming the technology. The merging of people and technology will make how we understand what it means to be human no longer applying. There could still be “natural” people but there will also be “enhanced” people relying on the latest GRIN technology to augment their abilities. GRIN technology refers to genetic, robotic, information
The first way is that you accelerate away from a location that we will refer to as “at rest”, by accelerating back towards them you have effectively “skipped” a portion of time. This is due to spacetime being in balance so having such a large displacement of space means that time must move slower to balance that. Since the amount of time that has passed

The answer is about 14 billion years. The second method involves measuring the ages of the oldest star clusters. Globular star clusters orbiting our Milky
The universe is an unknown place. Most of it has not been explored. Some things are known, however. Scientists know a lot about things like the Big Bang and our Asteroid Belt. Some of the universe's natural phenomenons are yet to be discovered. This article will explain some of them and why they happen. In the year 1929, Edwin Hubble made a revolutionary discovery. He learned that the universe is expanding. He saw that the galaxies were each moving away from us. Edwin knew that for one instance of
from? When did space begin? Where does it end? These questions pushed Saul Perlmutter to a ground breaking discovery. Adam Riess and Brian Schmidt’s ambition led them to meet Perlmutter at the same conclusion. The universe’s rate of expansion is accelerating. It is being pushed apart by a mysterious dark energy. Zeeya Merali’s article “Confronting the Dark” follows Perlmutter, Schmidt, and Riess on their journey to discover dark energy. Throughout the article, we can apply of many of the basic ideas
the universe. Dark energy is the force that repels gravity which consists of about 70%. About 5% is the matter that we see today which includes stars and galaxies. Due to the fact that dark matter doesn’t interact with the electromagnetic force, dark matter doesn’t absorb, reflect or emit light. Dark energy doesn’t have local gravitational effects but it does affect the universe as a whole. The importance of dark matter and dark energy is that they make the majority of the mass in the universe. Dark
the show. This catchy and well known hit, consists of various, plausible, key facts describing the creation, formation and history of the universe. Is this theme song a reputable and reliable scientific source or is it just for a humorous, iconic and catchy appeal? The opening line of the song is a plausible and reliable scientific statement. “Our whole universe was in a hot dense state then nearly fourteen million years ago expansion started, wait! The Earth began to cool.” There is scientific evidence
research being conducted upon this unexplained force. Good Morning class, today my chosen topic is the term dark flow. Now dark flow is a basically a term used to explain astronomical observations, that appear to show certain areas of space accelerating and expanding at a rate that is abnormal in comparison to surrounding regions and the expectation of the acceleration rate that is formed from the basis of laws, rules and models. However,these observations have profound controversy in the scientific
there was an extra-ordinary event without which nothing would exist. It was the beginning of the universe. It was the time when a large amount of energy in an infinitely small space violently expanded and led to the creation of universe and everything else that we see around us today. It can perhaps be regarded as the greatest scientific achievement to understand the history and nature of how the universe came into being. There are various viewpoints on what happened before the Big Bang, however it
long-ago ancestors did, one can only get a small idea as to the size of the universe. A telescope allowed us to see further and expanded our understanding. Today's research goes even further, and greatly augments our knowledge of the universe. In fact, the universe is so big that no one knows exactly how big it is, because light simply cannot travel fast enough to illuminate it. Now, take that, our one infinitely big universe, and multiply it by infinity. Now, you have the idea of the multiverse, a
Introduction Gravity, the invisible force that pulls objects toward the ground, has existed long before Earth’s creation. Gravity, in various degrees, can be found on every moon, planet, solar system, galaxy, and universe, expanding into systems far beyond the reach of human awareness. The study of gravity can be documented as far back as around 300 BCE, during the time of Aristotle, with the theory that larger or heavier objects fall to the ground faster than smaller or lighter objects. Over
help us know how the universe began. These two are the mysteries of the universe; they compose about 90% of the universe. They are mysteries because we believe that they exist but we can’t see them or detect them. People question whether they manifest to be the same thing. Astronomers know very little about their constitution so they cannot assume they are related. Dark Energy is a mysterious force that drives the expansion of the universe. Astronomers states that the universe is expanding and the
The way in which we currently view the structure of the universe has been developed throughout centuries by various astronomers whose predictions and observations have all aided in the development of this model. Aristotle based his model of the universe on Pythagorean theory which described the Earth as a sphere. His claims of a round Earth were reinforced by three observations. The first of these was that all Earthly matter moved towards the centre of the Earth, and this would consequently produce
What is the concept of time travel exactly? Time travel is the action of travelling in time to the past or future. Even though, is it even possible to travel in time and how would you travel through time? Well, according to Einstein's theory of time, it is possible to travel through time by going faster than the speed of light (186282 miles per second). We humans know the goal that we need to reach to actually time travel but the technology that has been developed today is not advanced far enough
ever know for certain, how the universe ever came into existence. Cosmologists have uncovered multiple viable theories that explain the advent of the universe, but we assume that there can only be one. In 1927, Georges Lemaître suggested that the universe began at a moment in time and from there everything expanded exponentially outward from that single point. Lemaître’s model was only one of many developed that genuinely offered an explanation to how the universe was created. Lemaître’s model was
Darwin, Kelvin, Pauling, Hoyle, and Einstein. He chose these five because he understood that these are highly recognizable names, whose individual errors are all related through evolution. That is, through the evolution of life, earth, stars and the universe as a whole. Darwin discovered natural selection. This proclaims that all living beings did not arise, as they are, out of thin air. Each had adapted to their environment over time, allowing nature to choose those who were most fit for survival.
most part, agreed upon, but the implications of such travel is not so decided upon. Many different theorists have different views of what could happen and some go, as far as to say that if we did travel to the past, we would end up in a different universe that is a replica of this one. One of the most basic concepts is that of Dilation, a stretching of something. Some scientists believe that the main gateway to the past or future is a wormhole. Einstein’s general relativity theory explains about universal
something about Space. Now i sound over dramatic and outrageous with my “ we will die along with your dreams” attitude, but seriously black holes are really cool and pretty magnificent, as long as you don't underestimate the power they have over the universe and our galaxy as a we know it. Black holes are the remains after a large star dies in a supernova
