The universe can be divided into the entire universe, which is potentially infinite in size, and the observable universe, which is finite and has a diameter of about 93 billion light years. The age of the universe is estimated to be between 10-20 billion years based on calculations from the Big Bang theory. While about 5% of the universe is made up of known substances like stars, planets, and gases, a vast majority - about 95% - consists of mysterious "dark matter" and "dark energy" about which little is understood.

What do you know about EGYPT ? (Dec.05,2012)Ahmad Usama
This document provides information about Egypt. It begins with the origin of Egypt's name and discusses the meaning of names like Kemet and Misr. It then covers Egypt's flag and its evolution over time. The document locates Egypt in Africa and provides a political map. Additional sections discuss Egypt's geography, climate, economy, and key features like the Nile River.
The document summarizes theories about the origin and evolution of the universe. It describes the widely accepted Big Bang theory, which proposes that the universe began in a hot, dense state and has been expanding ever since. It also briefly outlines alternative theories such as inflationary universe, stationary universe, and oscillating universe. Finally, it provides an overview of the major events and epochs in the development of the universe according to the Big Bang theory, from the initial singularity to the formation of stars and galaxies.
Ancient Egypt had a strong civilization that began around 3200 BC. The geography of Egypt, especially the flooding of the Nile River, supported the rise of Egyptian culture. Egyptians developed hieroglyphic writing, built pyramids and temples, practiced mummification, and had a society led by powerful pharaohs. Over time, foreign invaders like the Hyksos challenged Egyptian rule. The New Kingdom saw a revival of Egyptian power until internal struggles and outside pressures contributed to the decline of their empire, though Nubian kings later formed a Kush Empire influenced by Egyptian traditions.
The document is a summary of the planets and moons in our solar system. It provides details on each planet's orbit around the sun, distance from the sun, gravity, atmosphere and notable features. It also describes Earth's moon and its formation from asteroid impacts over time.
