And no life is around to witness it, does the universe exist?
Matter is anything that has mass and takes up space. It is the physical substance that makes up the universe and everything in it.
The exact amount of matter in the universe is unknown, but it is estimated to be around 5% of the total energy content of the universe. The remaining 95% is believed to be made up of dark matter and dark energy.
Matter is formed through the process of nucleosynthesis, which occurs during the early stages of the universe's evolution. This involves the fusion of atoms to create heavier elements, such as hydrogen and helium.
According to the law of conservation of mass, matter cannot be created or destroyed, only transformed into different forms. This means that the amount of matter in the universe remains constant, even though it may change in appearance or composition.
There are four known states of matter: solid, liquid, gas, and plasma. In addition, there are also various forms of matter, such as dark matter, which has not yet been directly observed but is believed to make up a significant portion of the universe's matter content.
