Top 10 Greatest Empires In History

FREIKORPTRASHER JUNE 22, 2010

The definition of an empire is: when a single entity has supreme rule and power over a vast area of territory, which consists of peoples of different ethnicity and nationality. This list is based on the influence, longevity and power of the various empires, and, as you will see, it contains at least one or two entries that may strike some as controversial. My one requirement for this list is that the empire must have been ruled – for at least a majority of the time – by an emperor or king. This excludes modern so-called empires such as the United States and Soviet Union. The entries here are listed roughly by influence and size.

Ottoman Empire

At the height of its power (16th–17th century), the Ottoman Empire spanned three continents, controlling much of Southeastern Europe, Western Asia and North Africa. It contained 29 provinces and numerous vassal states, some of which were later absorbed into the empire, while others were granted various types of autonomy during the course of centuries. The empire was at the center of interactions between the Eastern and Western worlds for six centuries. With Constantinople as its capital city, and vast control of lands around the eastern Mediterranean during the reign of Suleiman the Magnificent (ruled 1520 to 1566), the Ottoman Empire was, in many respects, an Islamic successor to the Eastern Roman (Byzantine) Empire.

Umayyad Caliphate

The Umayyad Caliphate was the second of the four Islamic caliphates (systems of governance), established after the death of Mohammed. It was ruled by the Umayyad dynasty, whose name derives from Umayya ibn Abd Shams, the great-grandfather of the first Umayyad caliph. Although the Umayyad family originally came from the city of Mecca, Damascus was the capital of their Caliphate. Eventually, it would cover more than five million square miles, making it the largest empire the world had yet seen, and the fifth largest contiguous empire ever to exist. The Umayyads established the largest Arab-Muslim state in history. From the time of Mohammed until 1924, successive and contemporary caliphates were held by various dynasties – the last being the Ottoman Empire (above).

Persian Empire

or Achaemenid Empire

Babylonian, Akkadians, Assyrians, Sumerians, Hitites, Bactrians, Scythians, Parthians, Medes, Elamites, Egyptians, Ethiopians… Before the Romans, there were the Persians. They basically unified the whole of Central Asia which consisted of a lot of different cultures, kingdoms, empires and tribes. It was the largest empire in ancient history. At the height of its power, the empire encompassed approximately 8 million km2. The empire was forged by Cyrus the Great, and spanned three continents: Asia, Africa and Europe.

7

Byzantine Empire

The Byzantine Empire, or Eastern Roman Empire, was the Roman Empire during the Middle Ages, centered on the capital of Constantinople, and ruled by emperors in direct succession to the ancient Roman emperors. It was called the Roman Empire, and also Romania. During its existence, of over a thousand years, the Empire remained one of the most powerful economic, cultural and military forces in Europe, despite setbacks and territorial losses, especially during the Roman–Persian and Byzantine–Arab Wars. The Empire received a mortal blow in 1204 by the Fourth Crusade, when it was dissolved and divided into competing Byzantine Greek and Latin realms. Despite the eventual recovery of Constantinople and re-establishment of the Empire in 1261, under the Palaiologan emperors, successive civil wars in the fourteenth century further sapped the Empire’s strength.

Han Dynasty

During the Chinese period of warring states, the whole of China was embroiled in a civil war as the different kingdoms within it battled it out with each other in the quest for supremacy. In the end, the Qin State won, and gobbled up the whole of China, with 40 million people under it’s control. The Qin Dynasty didn’t last long, and soon it went to the Han, which eventually controlled China for close to 400 years. The period of the Han Dynasty is considered a golden age in Chinese history in terms of scientific achievement, technological advance, economic, cultural and political stability. Even to this day, most Chinese people refer to themselves as the Han people. Today, the “Han people” is considered the largest single ethnic group in the world.

I have never believed in the Big Bang Theory, it never seemed to make sense to me. It always seemed obviously wrong and flawed.

Now I am not sure where I got the idea described below, it could have been an article I read a long time ago, or the endless Science Fiction Novels I read as a child and youth but the below idea and article closely aligns with what I think about the Universe. I also believe that time has no beginning and no end and human intelligence is incapable of fully comprehending this....

(ISM) -- Our universe may exist inside a black hole. This may sound strange, but it could actually be the best explanation of how the universe began, and what we observe today. It's a theory that has been explored over the past few decades by a small group of physicists including myself.

Successful as it is, there are notable unsolved questions with the standard big bang theory, which suggests that the universe began as a seemingly impossible "singularity," an infinitely small point containing an infinitely high concentration of matter, expanding in size to what we observe today. The theory of inflation, a super-fast expansion of space proposed in recent decades, fills in many important details, such as why slight lumps in the concentration of matter in the early universe coalesced into large celestial bodies such as galaxies and clusters of galaxies.

But these theories leave major questions unresolved. For example: What started the big bang? What caused inflation to end? What is the source of the mysterious dark energy that is apparently causing the universe to speed up its expansion?

The idea that our universe is entirely contained within a black hole provides answers to these problems and many more. It eliminates the notion of physically impossible singularities in our universe. And it draws upon two central theories in physics.

The first is general relativity, the modern theory of gravity. It describes the universe at the largest scales. Any event in the universe occurs as a point in space and time, or spacetime. A massive object such as the Sun distorts or "curves" spacetime, like a bowling ball sitting on a canvas. The Sun's gravitational dent alters the motion of Earth and the other planets orbiting it. The sun's pull of the planets appears to us as the force of gravity.

The second is quantum mechanics, which describes the universe at the smallest scales, such as the level of the atom. However, quantum mechanics and general relativity are currently separate theories; physicists have been striving to combine the two successfully into a single theory of "quantum gravity" to adequately describe important phenomena, including the behavior of subatomic particles in black holes.

A 1960s adaptation of general relativity, called the Einstein-Cartan-Sciama-Kibble theory of gravity, takes into account effects from quantum mechanics. It not only provides a step towards quantum gravity but also leads to an alternative picture of the universe. This variation of general relativity incorporates an important quantum property known as spin. Particles such as atoms and electrons possess spin, or the internal angular momentum that is analogous to a skater spinning on ice.

In this picture, spins in particles interact with spacetime and endow it with a property called "torsion." To understand torsion, imagine spacetime not as a two-dimensional canvas, but as a flexible, one-dimensional rod. Bending the rod corresponds to curving spacetime, and twisting the rod corresponds to spacetime torsion. If a rod is thin, you can bend it, but it's hard to see if it's twisted or not.

Spacetime torsion would only be significant, let alone noticeable, in the early universe or in black holes. In these extreme environments, spacetime torsion would manifest itself as a repulsive force that counters the attractive gravitational force coming from spacetime curvature. As in the standard version of general relativity, very massive stars end up collapsing into black holes: regions of space from which nothing, not even light, can escape.

Here is how torsion would play out in the beginning moments of our universe. Initially, the gravitational attraction from curved space would overcome torsion's repulsive forces, serving to collapse matter into smaller regions of space. But eventually torsion would become very strong and prevent matter from compressing into a point of infinite density; matter would reach a state of extremely large but finite density. As energy can be converted into mass, the immensely high gravitational energy in this extremely dense state would cause an intense production of particles, greatly increasing the mass inside the black hole.

The increasing numbers of particles with spin would result in higher levels of spacetime torsion. The repulsive torsion would stop the collapse and would create a "big bounce" like a compressed beach ball that snaps outward. The rapid recoil after such a big bounce could be what has led to our expanding universe. The result of this recoil matches observations of the universe's shape, geometry, and distribution of mass.

In turn, the torsion mechanism suggests an astonishing scenario: every black hole would produce a new, baby universe inside. If that is true, then the first matter in our universe came from somewhere else. So our own universe could be the interior of a black hole existing in another universe. Just as we cannot see what is going on inside black holes in the cosmos, any observers in the parent universe could not see what is going on in ours.

The motion of matter through the black hole's boundary, called an "event horizon," would only happen in one direction, providing a direction of time that we perceive as moving forward. The arrow of time in our universe would therefore be inherited, through torsion, from the parent universe.

Torsion could also explain the observed imbalance between matter and antimatter in the universe. Because of torsion, matter would decay into familiar electrons and quarks, and antimatter would decay into "dark matter," a mysterious invisible form of matter that appears to account for a majority of matter in the universe.

Finally, torsion could be the source of "dark energy," a mysterious form of energy that permeates all of space and increases the rate of expansion of the universe. Geometry with torsion naturally produces a "cosmological constant," a sort of added-on outward force which is the simplest way to explain dark energy. Thus, the observed accelerating expansion of the universe may end up being the strongest evidence for torsion.

Torsion therefore provides a theoretical foundation for a scenario in which the interior of every black hole becomes a new universe. It also appears as a remedy to several major problems of current theory of gravity and cosmology. Physicists still need to combine the Einstein-Cartan-Sciama-Kibble theory fully with quantum mechanics into a quantum theory of gravity. While resolving some major questions, it raises new ones of its own. For example, what do we know about the parent universe and the black hole inside which our own universe resides? How many layers of parent universes would we have? How can we test that our universe lives in a black hole?

The last question can potentially be investigated: since all stars and thus black holes rotate, our universe would have inherited the parent black hole’s axis of rotation as a "preferred direction." There is some recently reported evidence from surveys of over 15,000 galaxies that in one hemisphere of the universe more spiral galaxies are "left-handed", or rotating clockwise, while in the other hemisphere more are "right-handed", or rotating counterclockwise. In any case, I believe that including torsion in geometry of spacetime is a right step towards a successful theory of cosmology.
