Earth was formed in how many days?
Earth was formed 4.5 billion years ago. How do we know this? From analyzes of ancient rocks on Earth and the Moon and the half-lives of uranium isotopes in them. This method is called radiometric dating.
How long did the earth take to form? It took 1 to 2 million years for the earth to take its initial form. Now how do we know this? Because Aql-e-Salim or Aql-e-Munir understands that unless you are present in the past, you cannot know about the past. We know about the past from radiometric dating, from the fundamental principles of the universe, and from mathematical models built from those principles and then from computer simulations. We cannot exist when the earth was being formed
: ow that you have an idea of the shapes and sizes of the people in your country, you will not be able to tell the age group of the people in this unknown city by their shapes and sizes. However, with repeated observation you will begin to get a better idea of how old a child is, what a young man looks like, what middle age is like, etc.
Just like that. Now see that the universe is your observatory where new stars are formed and come to an end every day, just as new people are born and die on earth every day.
: So by observing the stars in the universe you can determine their age, you can tell which star is in which part of its age. With some of his special signs. Just as you can tell the age of a child by looking at his milk teeth, or like when a person is approaching old age, you know that he is in the last part of his life by his sagging waist or white hair.
This is the case with the stars. Fusion takes place in stars. Stars shine differently during their "lifetimes" depending on their mass and size
Sometimes extremely bright (when new ones form, sometimes extremely dim when fusion stops, etc. etc.). This is exactly how we know when the sun was formed.
: When we came to know about the birth of the sun, we also came to know that the earth was also formed more or less at the same time when the sun was formed. That they are all part of the solar system.
Regarding the birth of the earth, we know that the earth is 4.5 billion years old from the presence of elements like uranium in the ancient rocks on the earth and the moon and the ratio of its different isotopes.
Now that we know all this, the question remains that how long did the earth take to form?
We know this by entering into computer models the fundamental principles of the universe (from the laws of gravity, from the motion of gases and rotation), how rocks in space bond together over time, and a giant planet or asteroid. or make the moon
: So when we make computer models and add the amount of matter (gases, dust, space rocks, etc.) in the early solar system, we see that it would have taken one to two million years for the Earth to form.
