The Universe
Creation of the universe
_______________________
At the very beginning this universe was the power of hot and dense radiation.
At a fraction of a thousandth of a second, tiny radiation generates tiny energies that create two new energies that we know as hydrogen and helium.
This combines hydrogen and helium to form the first star.
The nuclear reaction inside the star produces some more energy, which is carbon and oxygen.
The combination of all these causes an explosion known as the "Big Bang".
The age of the universe
Our universe is about 13.6 billion years old. Isn't it weird?
The elements of the universe
We have different elements of the vast universe. Find out the names of some of those elements.
1) Sun: We see every morning because of this sun. Survive because of this sun. The circumference of the sun is 1.4 million kilometers !!!!
If you want to know more about the sun, watch the episode above.
2) Planets: We also have this earth among the planets. Our earth is nothing compared to the size of the universe. Apart from the earth, there are some other planets such as Mars, Mercury, Saturn, Venus etc.
3) Tara Mandal: The white stars that we see in the sky at night are a mixture of different gases. They glow brightly. Our sun is also a star.
4) Galaxies: They exist within the galaxy.
Strange information
At the very beginning of the creation of the universe, its temperature was 10 billion trillion trillion degrees. !!!!!!!!!!!!!
The first human feet were on the earth 1 million years ago after the creation of the earth.
Distance gauge
There are various ways to measure the distance of the universe. Find out below.
Kilometers / Miles: Kilometers or miles are used to measure near distances, such as the distance or circumference of the Earth, Chad, and the Sun.
Astronomical Unit: This measurement is used to measure the distance from planet to planet.
Light years: Light years are used to measure distances between different elements of a galaxy. One light year = 9.45 million million kilometers.

Some more information:
Everything we see in the sky is due to light. They have their own light. Others do not but because of the reflection of light they are seen to be burning which includes the moon, even the earth.
The speed of light is the highest. You will be surprised to hear that the speed of light is 1,6,26 miles per second.
The distance between the stars is still the same as before.
The longest distance of our galaxy from Earth is 13 billion light years away from Earth (one light year = 9.45 million million kilometers).
