Answer: The universe (Latin: universus) is all of space and time[a] and their contents,[10] including planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the prevailing cosmological description of the development of the universe. According to this theory, space and time emerged together 13.787±0.020 billion years ago,[11] and the universe has been expanding ever since the Big Bang. While the spatial size of the entire universe is unknown,[3] it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.
The earliest cosmological models of the universe were developed by ancient Greek and Indian philosophers and were geocentric, placing Earth at the center.[12][13] Over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the center of the Solar System. In developing the law of universal gravitation, Isaac Newton built upon Copernicus's work as well as Johannes Kepler's laws of planetary motion and observations by Tycho Brahe.
Further observational improvements led to the realization that the Sun is one of a few hundred billion stars in the Milky Way, which is one of a few hundred billion galaxies in the universe. Many of the stars in a galaxy have planets. At the largest scale, galaxies are distributed uniformly and the same in all directions, meaning that the universe has neither an edge nor a center. At smaller scales, galaxies are distributed in clusters and superclusters which form immense filaments and voids in space, creating a vast foam-like structure.[14] Discoveries in the early 20th century have suggested that the universe had a beginning and that space has been expanding since then[15] at an increasing rate.[16]
According to the Big Bang theory, the energy and matter initially present have become less dense as the universe expanded. After an initial accelerated expansion called the inflationary epoch at around 10−32 seconds, and the separation of the four known fundamental forces, the universe gradually cooled and continued to expand, allowing the first subatomic particles and simple atoms to form. Dark matter gradually gathered, forming a foam-like structure of filaments and voids under the influence of gravity. Giant clouds of hydrogen and helium were gradually drawn to the places where dark matter was most dense, forming the first galaxies, stars, and everything else seen today.
From studying the movement of galaxies, it has been discovered that the universe contains much more matter than is accounted for by visible objects; stars, galaxies, nebulas and interstellar gas. This unseen matter is known as dark matter[17] (dark means that there is a wide range of strong indirect evidence that it exists, but we have not yet detected it directly). The ΛCDM model is the most widely accepted model of the universe. It suggests that about 69.2%±1.2% [2015] of the mass and energy in the universe is a cosmological constant (or, in extensions to ΛCDM, other forms of dark energy, such as a scalar field) which is responsible for the current expansion of space, and about 25.8%±1.1% [2015] is dark matter.[18] Ordinary ('baryonic') matter is therefore only 4.84%±0.1% [2015] of the physical universe.[18] Stars, planets, and visible gas clouds only form about 6% of the ordinary matter.[19]
There are many competing hypotheses about the ultimate fate of the universe and about what, if anything, preceded the Big Bang, while other physicists and philosophers refuse to speculate, doubting that information about prior states will ever be accessible. Some physicists have suggested various multiverse hypotheses, in which our universe might be one among many universes that likewise exist.[3][20][21]

What i a major difficulty that tate legilator face in meeting the demand many American place on their tate government?
Answers
The Constitution cannot be amended by the State Legislature. A significant challenge that state legislators face in fulfilling the demands that many Americans place on their state government is that a significant portion of the Constitution can be amended by the Parliament.
The purpose of Congress is to represent the will of the people by passing laws that affect everyone's daily lives. Its duties include providing funds for government operations and initiatives, holding hearings to educate lawmakers, and supervising the executive branch.
The legislature's authority is constrained by the constitution itself. A state's legislature is not allowed to exercise any authority that is not explicitly granted by the constitution.
Laws are created by the legislative branch, but the President, who is part of the executive branch, has the power to veto them.

before the seventeenth century, why was southern africa such an important trading hub for europeans?
Answers
It was about halfway between Europe and Asia because of this southern Africa such an important trading hub for Europeans.
In the economic history of precolonial Africa, trade between European and African states very recently emerged. African kings and traders had already established trading ties with the Mediterranean, western Asia, and the Indian Ocean area before the European explorers arrived in the fifteenth century. Local interactions between nearby populations on a continent integrate within a larger framework of long-distance trade.
Therefore, the traders from Britain, France, Portugal, and the Netherlands found a well-established trading populace governed by shrewd and experienced local rulers throughout the Atlantic coast of Africa. In order to keep commodities and protect their trade rights from outside intrusion, European businesses swiftly established commercial relationships with these indigenous authorities and built fortified "factories," or warehouses, on coastal locations. From modern-day Senegal to Angola, independent Portuguese traders known as lançados established themselves along the continent's rivers and coasts. There, they assimilated into African culture and acted as middlemen between European and African traders.

Which statement best describes free Black people before the Civil War?
A. Most free Black people lived in southern cities.
B. Free Black people formed vibrant communities in urban centers.
C. Free Black people were protected from kidnappings by legal documents that showed their status as free.
Answers
Answer:
Free blacks in the antebellum period—those years from the formation of the Union until the Civil War—were quite outspoken about the injustice of slavery. Their ability to express themselves, however, was determined by whether they lived in the North or the South. Free Southern blacks continued to live under the shadow of slavery, unable to travel or assemble as freely as those in the North. It was also more difficult for them to organize and sustain churches, schools, or fraternal orders such as the Masons. Although their lives were circumscribed by numerous discriminatory laws even in the colonial period, freed African Americans, especially in the North, were active participants in American society. Black men enlisted as soldiers and fought in the American Revolution and the War of 1812. Some owned land, homes, businesses, and paid taxes. In some Northern cities, for brief periods of time, black property owners voted. A very small number of free blacks owned slaves. The slaves that most free blacks purchased were relatives whom they later manumitted. A few free blacks also owned slave holding plantations in Louisiana, Virginia, and South Carolina. Free African American Christians founded their own churches which became the hub of the economic, social, and intellectual lives of blacks in many areas of the fledgling nation. Blacks were also outspoken in print. Freedom's Journal, the first black-owned newspaper, appeared in 1827. This paper and other early writings by blacks fueled the attack against slavery and racist conceptions about the intellectual inferiority of African Americans. African Americans also engaged in achieving freedom for others, which was a complex and dangerous undertaking. Enslaved blacks and their white sympathizers planned secret flight strategies and escape routes for runaways to make their way to freedom. Although it was neither subterranean nor a mechanized means of travel, this network of routes and hiding places was known as the “underground railroad.” Some free blacks were active “conductors” on the underground railroad while others simply harbored runaways in their homes. Free people of color like Richard Allen, Frederick Douglass, Sojourner Truth, David Walker, and Prince Hall earned national reputations for themselves by writing, speaking, organizing, and agitating on behalf of their enslaved compatriots. Thousands of freed blacks, with the aid of interested whites, returned to Africa with the aid of the American Colonization Society and colonized what eventually became Liberia. While some African Americans chose this option, the vast majority felt themselves to be Americans and focused their efforts on achieving equality within the United States.
