It may be like a black hole, which is a singularity sincegravity in a black hole becomes boundless.
Others like Stephen Hawking say "time" did not exist and was only born with the universe. Hence the universe does not have an origin story. Time did not exist before the creation of the universe.
There is currently no theoretical model that explains the earliest moments of the universe's existence (during the Planck time). This is because we lack a testable theory of quantum gravity. Still, some researchers in string theory, M theory, and loop quantum cosmology have some ideas.
There are certain myths that also propose how the universe was created: for example creation myths in the Bible, the Dào Dé Jīng, and other genesis stories. These usually involve
The Eridu Genesis, written on Sumerian tablets, is one of the oldest creation myths. The universe was created from a sea (Abzu). In Greek mythology, Zeus created the universe from chaos.
Cosmology studies the universe in general. You can still study the universe without thinking about its origin, which is what cosmonogy studies specifically.
History of Russia
The history of Russia begins with the East Slavs, Turkic, and the Finno-Ugric peoples. Parts of Southern Russia around the Black sea were settled by Greeks and Romans until about the 3rd century. Huns and Turkic tribes invaded the regions around the Black sea until the 10th century. Eastern Slavs then immigrated to the region. Vikings created the Kievan Rus. In the 13th century, Mongols conquered the region and created the Golden Horde. The Mongols ruled until the 15th century. The tsardom of Russia and Russian empire were then created. Poland-Lithuania invaded Moscow, but Russia eventually drove them out. Russia expanded more west and east into Siberia. Napoleon tried to invade Russia during the winter but failed. Russia fought against Germany in WW1. In 1917, the October Revolution happened, and the communists led by Lenin created the Soviet Union. In WW2, Hitler also failed to invade Russia. Russia occupied East Germany, Poland, and most of East Europe during the Cold War. It became a big rival of the United States. In the 1990s, the Union ended, with things like the Yugoslavia revolution, and became modern Russia. In 2014 Russia annexed Crimea from the Ukraine and faced sanctions from US and others because of it.
In the 8th century BCE, Greek merchants migrated to Tanais and Phanagoria. The Bosporan Kingdom (a Greek kingdom) became part of the Roman Empire. In the 2nd century AD Germanic Goths migrated to the Black Sea. In the 3rd and 4th centuries AD, the Gothic Oium existed in Southern Russia until it was conquered by Huns.
Between the 3rd and 6th centuries AD, the Bosporan Kingdom was also invaded by Eastern nomads like the Huns and Turkish Avars.
A Turkic people, the Khazars, conquered the lower Volga basin steppes between the Caspian and Black Seas up to the 8th century. They were known for their laws, tolerance, and cosmopolitanism. The Khazars traded with the Baltic and the Muslim Abbasid empire centered in Baghdad. They were important allies of the Byzantine Empire, and helped win wars against Arab Caliphates. In the 8th century, the Khazars became Jewish.
Some of the ancestors of the modern Russians were the Slavic tribes. They came from the forests of the Pripet Marshes. The Early East Slavs gradually settled Western Russia by moving from Kiev towards present-day Suzdal and Murom and then from Polotsk towards Novgorod and Rostov.
From the 7th century onwards, East Slavs were the majority of Western Russia. They mixed slowly and peacefully with the native Finno-Ugric tribes, such as the Merya, the Muromians, and the Meshchera.
The Cyrillic alphabet, invented in modern Bulgaria in the 9th century, also spread during this period.
Vikings or Varangians did piracy and trade throughout Northern Europe. In the mid-9th century, they conquered the eastern Baltic to the Black and Caspian Seas. A Varangian named Rurik became ruler of Novgorod in about 860, before they moved south and conquered Kiev, which had been previously belonged to the Turkic Khazars. Rurik's son Igor and Igor's son Sviatoslav then conquered the East Slavic tribes, destroyed the Khazar khaganate, and fought wars against Byzantium and Persia.
Thus, Rus' was born in the 9th century along the Dnieper River valley. The Kievan Rus' controlled the trade for furs, wax, and slaves between Scandinavia and the Byzantine Empire along the Volkhov and Dnieper Rivers.
Near the 11th century, the Norse ruling class mixed with the Eastern Slavs. The Slavs absorbed Greek Christian influences when trying to loot Constantinople. Svyatoslav I claimed victory in one such campaign; he also defeated the Khazars on the Volga. The Byzantine Empire was declining but would influence Russia culturally.
For example through the Byzantine, the Kievan Rus' introduced the Slavic variant of the Eastern Orthodox Christianity. They became Christian in 988.
Then Yaroslav the Wise wrote some laws.
By the 11th century, Yaroslav the Wise helped improve the economy and literature. The Russian language was not that influenced by Greek and Latin. Church Slavonic was used directly in liturgy instead.
A nomadic Turkic people, the Kipchaks (or Cumans), replaced earlier Pechenegs in the south steppe at the end of the 11th century. They founded a nomadic state along the Black Sea (Desht-e-Kipchak). The Kipchaks and Kievs fought.
The Rus were conquered by the Mongol Golden Horde in the 13th century. Kiev was destroyed. Halych-Volhynia would eventually be absorbed into the Polish–Lithuanian Commonwealth, while the Mongol-dominated Vladimir-Suzdal and independent Novgorod Republic became the basis for modern Russia.
In 1223, the disunited southern princes faced a Mongol raiding party at the Kalka River and were soundly defeated. In 1237–1238 the Mongols burnt down the city of Vladimir (4 February 1238) and other major cities of northeast Russia, defeated the Russians at the Sit' River, and then moved west to conquer Poland and Hungary. By then they had conquered most of Russia.
The Mongols destroyed the cities. Some like Kiev and Vladimir never recovered. The new cities of Moscow, Tver and Nizhny Novgorod began to compete for hegemony in the Mongol-dominated Russia. The Golden Horde was established in the 14th century. Mongol domination of the Russia, along with demands of tribute from Russian princes, continued until about 1480.
After the fall of the Turkic Khazars in the 10th century, the Volga were conquered by the Volga Bulgaria, part of Greater Bulgaria. In the 10th century the Turks converted to Islam and traded with the Middle East and Central Asia. After the Mongol invasions of the 1230s, Volga Bulgaria was annexed by the Golden Horde. Its population evolved into the modern Chuvashes and Kazan Tatars.
The Mongols controlled Russia and Volga Bulgaria from their western capital at Sarai, one of the largest cities of the medieval world. Russian princes had to pay tribute to the Mongols of the Golden Horde, commonly called Tatars. The Russian Orthodox Church even experienced a revival under the Metropolitan Alexis and Sergius of Radonezh.
The Mongols influenced Russian military tactics and transportation. Under Mongol occupation, Russia developed its postal road network, census, fiscal system, and military organization.
Daniil Aleksandrovich founded Moscow (Muscovy). They were first a vassal to the Mongols and Tatars.
The Mongol rulers gave them the title of Grand Prince of Moscow and made them collect tribute from the Russian principalities. Moscow became the center of the Russian Orthodox Church.
In the 15th century, the princes of Moscow continued to consolidate Russian land to increase their population and wealth. The most successful one was Ivan III, who laid the foundations for the Russian nation. Ivan competed with the Grand Duchy of Lithuania for control over the upper Dnieper and Oka River basins.
