What is Big Bang?
The Big Bang happened 13.8 billion years ago today. The Big Bang was not an explosion, but it refers to the event of the beginning of the universe when the universe expanded rapidly and is still expanding. At the time of the Big Bang, the Earth was not connected to any object, nor was it later. Earth came into existence 4.6 billion years ago when our solar system and its other planets formed. At the beginning of the Earth, the length of the day was less than 12 hours because it rotated on its axis twice as fast as it does today. The earth was not formed in a week or days, but it took only 1 to 2 million years to form its initial form. When there was no life on early Earth, the Moon was closer to Earth. With time, the Moon moved away from the Earth and the Earth’s axial movement slowed down. Today, a day is approximately 24 hours long. Timekeeping and recording the length of the day began to be recorded by humans on Earth only a few hundred thousand years ago. The earliest form of the clock dates back to civilizations a few thousand years ago. Man started writing only five and a half thousand years ago. Many stories and legends of the past are only a few thousand years old. Science has increased human knowledge of the past, giving us a better understanding of the threats to human survival today. Human history and society is very interesting, read it to find out that life on earth is not as simple as you were told or told as a child.
