Soon the elements started to form, each on being created shortly after another. So then gravity showed up and started to do the job it was assigned to do. The gravity clumped them all up together and started creating planets, stars and many more piece of the universe. And soon humans came along with other living creatures.

# data[].attributes.body
Right after the big bang the universe had started forming. It was still very hot and dense though, so the cool down process had started and lasted for some time. Since it started to expand more it started to cool down as well. Then elements started to be created like protons, electrons and neutrons started to pop up. After that hydrogen was created with its one protons. Then thanks to the high energy and nuclear fusion, helium was created with 2 protons. And soon more kept getting created...

                                        Background About the Big Bang...

# data[].attributes.body
The Big Bang was the explosion or the reaction which started life and the universe. It was estimated to have been 13.8 billion years ago. It started causing our universe to start expanding further. The little dot that is quantified is said to have cause this massive explosion.

# data[].attributes.body
We don't really know what was there before the big bang, and it would be very hard to figure that out. For quantitative purposes we can say that everything in the whole universe was in a dot. Yes, a tiny little dot that is way smaller than the Earth etc. There is no way to prove that yet either.

A chemical change is when a element or product goes through a change which changes its properties or its chemical compounds change and it could also include changing it's form.

# data[].attributes.body
If something goes through a physical change, it most likely has to do with its appearance or its adjective like, height or mass or even shape.

There is always balance between the two sides. And after the fire burns not only the ashes are left but the oxygen as well that was used in the process which has now been turned into water vapor and carbon dioxide also counts, making both sides equal. And the molecule count among other things is the same as well.

# data[].attributes.body
Many other chemicals as well upon being combined keep the same molecule count. Based on this law there is always an iclibream of balance between the elements and there is no mass lost or created just like Einstein's famous discovery that said that there is no energy lost or created. There are the same amount of atoms too.

If there is a campfire, and there is 10 pounds of wood. The mass of that wood would be the same as the ash and oxygen (water vapor and carbon dioxide). In this way there is a balanced mass, and an equal one between the reactants and the products.

But the truth was that instead of the galaxies moving away from the Milky way itself, instead it was vice versa. The space that was between the Milky Way and galaxies was expanding sending the galaxies farther away from the Milky Way.

In the year 1925, the Astrophysicist Edwin Hubble made a discovery that the universe was expanding. And in 1929 declared his new findings and research. He said the galaxy's were moving farther away from each other.

If the universe was stationary there would be no reading. But in fact there is a reading which means the universe is actually not stationary and actually still expanding. And the radiation proves that the temperature is still there that had originated from the big bang.

On the date of May 20, 1664, Robert Wilson and Arno Penzias had measured the background radiation in the universe. using a microwave receiver. If the universe would be static, the measure would be 0 kelvins because there would be no heat between objects. But instead, the astrophysicists found themselves getting a reading of 3 kelvin.

The law of conservation of mass is the law that says that mass is neither created or destroyed by any chemical reaction, etc. And that the mass of elements in  chemical reactions has to equal the mass of the reactants and vice-versa.

# data[].attributes.body
The law that confirms that no mass of matter is lost in the universe in any reaction.
