Activity 3: Big bang, the origin and the expansion of the Universe

The Big Bang Theory:
The matter of the entire universe came from a very hot central point. Sooner or later, the center point began to cool ... 15 million years ago

Back then, these atoms were united by gravity. This region exploded and the matter extended by all the territory
universe

In the first second after the universe, the surrounding temperature was about 10 billion degrees Fahrenheit (5.5 billion degrees Celsius).

The cosmos contained a wide range of fundamental particles, such as neutrons, electrons, and protons. These vanished or merged as the universe cooled.

Activity 2: Astronomer's timeline

Activity 1: Famous Astronomers

Name:	Albert Einstein	Tycho Brahe	Isaac Newton	Harlow Shapley	Johannes Kepler
Date of birth:	March 14, 1879,	December 14, 1546,	January 4, 1643	November 2, 1885,	December 27, 1571
Main thinking:	I never came upon any of my discoveries through the process of rational thinking.	Proposed a theory of the solar system, which contained elements of both the Earth-centred Ptolemaic system and the Sun-centred Copernican system.	That gravity was the force of attraction between two objects, such as an apple and the earth.	Shapley used RR Lyrae stars to estimate the size of the Milky Way Galaxy and the Sun's position within it by using parallax.	The ways by which men arrive at knowledge of the celestial things are hardly less wonderful than the nature of these things themselves.
