Slide 3:

Formation of the Universe

Slide 5:

Is all of time and space and its content. It includes planets, moons, minor planets, stars, galaxies and all matter and energy. What is Universe?

Slide 6:

The earliest scientific models of the universe where develop by Ancient Greek and Indian Philosophers.

Slide 7:

Over the centuries more precise astronomical observation led by

Slide 8:

Nicolaus Copernicus (1473-1543) to develop the heliocentric model with the sun at center of the solar system.

Slide 10:

Isaac Newton (1643-1727) in developing the law of universal gravitation .

Slide 12:

Johannes Kepler (1571-1630) Law of planetary motion .

Slide 15:

The Big Bang Theory states that the  universe  was  formed  about 14 billion years ago as the result of a giant explosion of very dense and hot matter.

Slide 16:

The first scientist to come up with the idea of a 'big bang' was the astrophysicist

Slide 17:

Friedrich Franz Friedmann

Slide 20:

According to the Boshongo people of central Africa, in the beginning, there was only darkness, water, and the great god Bumba . One day Bumba , in pain from a stomach ache, vomited up the sun. The sun dried up some of the water, leaving land. Still in pain, Bumba vomited up the moon, the stars, and then some animals. The leopard, the crocodile, the turtle, and finally, man.

Slide 22:

However in 1915, Einstein introduced his revolutionary General Theory of Relativity. In this, space and time were no longer Absolute, no longer a fixed background to events. Instead, they were dynamical quantities that were shaped by the matter and energy in the universe.

Slide 24:

Steady State theory, as galaxies moved apart, the idea was that new galaxies would form from matter that was supposed to be continually being created throughout space. The universe would have existed for ever and would have looked the same at all times.

Slide 27:

Scientists believe that the  solar system  was  formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust.

Slide 28:

The formation of the  Solar System  began 4.6  billion  years ago with the  gravitational collapse  of a small part of a giant molecular cloud .

Slide 29:

This model, known as the  nebular hypothesis , was first developed in the 18th century by  Emanuel Swedenborg ,  Immanuel Kant , and  Pierre-Simon Laplace .

Slide 31:

Emanuel Swedenborg was a Swedish scientist, philosopher, theologian, revelator, and mystic.

Slide 32:

Immanuel Kant was a German philosopher who is considered the central figure of modern philosophy.

Slide 33:

Pierre-Simon, marquis de Laplace was an influential French scholar whose work was important to the development of mathematics, statistics, physics, and astronomy
