Science deals with building a body of knowledge through evidence-based investigations and observations. It aims to explain phenomena based on the available evidence but does not aim to offer absolute proof. This is because scientific understanding is always evolving with new evidence and perspectives.
The Kelvin scale is used in the scientific study of gases and very cold temperatures. It is an absolute temperature scale where 0 K is considered absolute zero, the point at which all molecular motion ceases.
Gravity is considered a theory rather than a fact because it is a scientific explanation that has been extensively tested and supported by evidence, but it is still subject to refinement and further study. Theories in science are not considered absolute truths, but rather the best explanations based on current knowledge and evidence.
In science, proof refers to evidence or data that supports a hypothesis or theory. Proof is not absolute; rather it is a level of confidence based on the weight of evidence gathered through observations, experiments, and analysis. Scientific proof is always subject to revision or change based on new information or discoveries.
The unit of inferred absolute zero is in Kelvin (K). The Kelvin scale is based on absolute zero, which is the theoretical temperature at which all molecular motion ceases. It is commonly used in scientific measurements and calculations due to its direct relationship with the ideal gas law and other thermodynamic principles.

If my memory of third grade serves me, that would be a theory. Theories are based upon observations (e.g.: Observation: That guy's left side looks limp. Theory: He had a stroke) and are not absolute, as until it is tested and proven, there is no way to tell for certain if a theory is true or not.
Scientific knowledge is not absolute.
All scientific theories are basically just consensuses of postulates to guide scientific research in a search for evidentiary proof. Consequently no theory is absolute fact. In the case of the Big Bang theory we also have the problem that we are trying to figure out what happened billions of years in the past, long before any human beings were around to observe those events directly. We have lots of astronomical observations which are relevant to this theory, but it is possible to imagine more than one way to interpret those observations. That said, you should also know that the evidence for the Big Bang theory is quite strong, and no one working in the field of cosmology has any serious doubt about it. It is very well supported. But it is not absolute fact. Nothing in science is taken as being absolute. For absolute truth, you must turn to religion.
a French philosopher: Thomas Hobbes
The mean absolute percent prediction error (MAPE), .The summation ignores observations where yt = 0.
It is all doubtable, testable and open to disproof. This is the strength of the scientific method; it is a heuristic. It does not lead to absolute truth. There are some basic observations that are probably undeniable for all of time, but the more speculative or theoretical a scientific principle is, the more it is vulnerable to change or re-interpretation.
I believe not.
It means that the observations are all close to their mean value.
