We can understand by nothing as the absence and nonexistence of some object. The term is used to cover the empirical need to represent the absence of something, because scientifically "nothing" does not exist. The origin of the word comes from the Latin res nata which means thing born , with which we can see that the term has been transversed from its conception.
In the common sense, the word is used to refer to the absence of some object at a certain time and place. For thousands of years, philosophers and theologians have tried to define nothingness or nonexistence, even daring to affirm that nothingness is a thing. In ancient Greece the concept arose with the denial of being, and the fact that you cannot speak of nothing, as there is nothing.
In science the term does not exist because everything in the cosmos can be represented, including emptiness, although in space absolute emptiness is very difficult to find, since in what is believed to be "empty space" there are usually garbage space to electromagnetic fields, no matter how tiny.
Physically it is almost impossible to find an area in the space-time dimension that does not contain things, since gravitational fields cannot be blocked, and if the determined region does not have an absolute temperature, it means that there are particles in that space, because any temperature greater than 0 absolute generates electromagnetic radiation.
In his time, Isaac Newton tried to prove nothingness, which he confused with a vacuum and determined it as "a massless medium" and even came to think of a hypothetical substance that occupied the vacuum, the ether theory, but Years later it was shown that the vacuum is something much more complicated, since in his time, Newton did not have the knowledge to demonstrate that in empty space there were gravitational fields, light waves and radiation, to name a few cases.
In mathematics, nothing can be represented as a null or neutral value, such as 0 in addition, 1 in multiplication, the identity matrix in multiple matrices, among others.
