The Great Attractor is a purported gravitational attraction in intergalactic space and the apparent central gravitational point of the Laniakea Supercluster. This supercluster contains the Milky Way, as well as about 100,000 other galaxies.
Whatever this Great Attractor is, it is so powerful that it has a mass capable of pulling millions and millions of stars towards it. Our own galaxy is moving towards this anomaly at a whopping 1,342,162 miles per hour. If the Earth moved that fast around the Sun, our years would only be 18 days long.
The Great Attractor has actually been explained now, and it's not by a supermassive black hole. The Great Attractor was a gravitational anomaly, as an immense mass seemed to pull on the Milky Way.
the observed velocities implied a mass of 5 x 1016 solar masses, a huge supercluster. This became known as the Great Attractor ( GA) model.
The Great Attractor is thought to be at the gravitational center of the Laniakea supercluster—of which the Milky Way is but one galaxy of 100,000 others. One theory is that it's a confluence of dark energy. Another is that it might be caused by over-density, an area of dense mass with an intense gravitational pull.
The focal point of that movement is the Great Attractor, the product of billions of years of cosmic evolution. But we'll never reach our destination because, in a few billion years, the accelerating force of dark energy will tear the Universe apart.
The largest stars will die and give way to neutron stars and black holes. Stars like our own sun will become white dwarfs. Red dwarfs will lose their ability to continue fusion, turning into black dwarfs—a strange kind of non-radiating stellar object that does not yet exist in our comparatively young universe.
The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It's so wide that light takes about 10 billion years to move across the entire structure.
The term dark matter was coined in 1933 by Fritz Zwicky of the California Institute of Technology to describe the unseen matter that must dominate one feature of the universe—the Coma Galaxy Cluster.
Azrael, the Great Attractor, is one of the Eight Old High Ones. He is the 'Death of Universes': an entity of unthinkably enormous scope and size — so vast that entire nebulae of galaxies are merely the glint in his eye. His sheer size suggests that Azrael may, in fact, be the universe itself.
If dark energy remains unchanging, space will expand indefinitely while increasingly isolated stars will slowly fade away and go cold, a phenomenon referred to as Heat Death. And if dark energy keeps accelerating the expansion of the universe, space itself will eventually be torn apart in the Big Rip.
These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe. What's more, these GRBs could be killing our chances of ever discovering life on other planets.
Because space isn't curved they will never meet or drift away from each other. A flat universe could be infinite: imagine a 2D piece of paper that stretches out forever. But it could also be finite: imagine taking a piece of paper, making a cylinder and joining the ends to make a torus (doughnut) shape.
According to their estimates the universe is 13.7 billion years old with an uncertainty of 200 million years.
The galaxies in our neighborhood are also rushing at a speed of nearly 1,000 kilometers per second towards a structure called the Great Attractor, a region of space roughly 150 million light-years (one light year is about six trillion miles) away from us.
Therefore, our universe is called the cosmos.
HD 140283 had a higher than predicted oxygen-to-iron ratio and, since oxygen was not abundant in the universe for a few million years, it pointed again to a lower age for the star. As a result of all of this work, Bond and his collaborators estimated HD 140283's age to be 14.46 billion years.
The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.
Furthermore, it also says in the Bible that 'the earth was formless and empty'. This shows that the universe started from nothing which does not contradict with scientific theories and rule out the big bang thesis. Therefore, God is the cause of the universe because he created all of it and made it out of nothing.
Stars are expected to form normally for 1012 to 1014 (1–100 trillion) years, but eventually the supply of gas needed for star formation will be exhausted. As existing stars run out of fuel and cease to shine, the universe will slowly and inexorably grow darker.
Even though certain features of the universe seem to require the existence of a multiverse, nothing has been directly observed that suggests it actually exists. So far, the evidence supporting the idea of a multiverse is purely theoretical, and in some cases, philosophical.
The Boötes Void (/boʊˈoʊtiːz/ boh-OH-teez) (colloquially referred to as the Great Nothing) is an approximately spherical region of space found in the vicinity of the constellation Boötes, containing very few galaxies, hence its name. It is enormous, with a radius of 62 megaparsecs.
The Great Attractor was first discovered in the 1970s when astronomers made detailed maps of the Cosmic Microwave Background (the light left over from the early universe), and noticed that it was slightly (and "slightly" here means less than one one-hundredth of a degree Fahrenheit) warmer on one side of the Milky Way ...
In astrophysics, dark flow is a theoretical non-random component of the peculiar velocity of galaxy clusters. The actual measured velocity is the sum of the velocity predicted by Hubble's Law plus a possible small and unexplained (or dark) velocity flowing in a common direction.
