Conservation is a LAW therefore true but I want to know why it happens what is the theory that explains it?
You mention conservation in general; there are several conservation laws, like conservation of energy, of linear momentum, of rotational momentum, of electrical charge, and others.
This is originally based on experience - for example, no cases are known where the linear momentum is violated.
However, these conservation laws (or many of them?) can be explained with Noether's Theorem. This is some very advanced math (for me, at least), but basically, it states that for every symmetry in nature, there is a corresponding conservation law. For example, the fact that the laws of physics are the same today as a year ago (they don't change over time) is related to the Law of Conservation of Energy; the Law of Conservation of Momentum is related to a symmetry with respect to position (the laws of nature are the same here as on the Moon), and the Law of Conservation of Rotational Momentum is related to a symmetry with respect to rotation (if you rotate an experimental apparatus, the results won't change).
What else can I help you with?
What explains why or how something happens?
it is a Theory! :)
Why a theory cannot become a law?
A theory and a law serve different purposes in science. A theory explains why something happens based on evidence and research, while a law describes a phenomenon or pattern observed in nature without necessarily explaining why it occurs. Therefore, a theory cannot "become" a law because they are fundamentally different in terms of their function and scope.
Does conservation of angular momentum disprove the big bang?
No, This assumes that the universe is a closed system, while this seems a reasonable hypothesis, the modern big bang theory actually states outright that the universe is not a closed system. Conservation of energy is also violated in the current model, the total energy of the universe is increasing.
What is the theory that explains how the continents move called?
The theory is Tectonics.
Why are Charles Darwins' ideas so important?
He proposed a theory that attempts to explain why and the fact of evolution works.It is, so far, the best and most accurate theory that adequately explains why evolution happens.
What is the difference between a theory and a principle?
A theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence. A principle is a fundamental truth or law that explains how a system works or how different variables interact. In essence, a theory explains why something happens, while a principle describes what is occurring.
What unites and explains a range of observation?
A theory unites and explains a range of observations.
What is the name of the theory that explains brown's observation?
The name of the theory that explains Brown's observation is the kinetic molecular theory of matter. This theory states that all matter is composed of particles (atoms or molecules) that are in constant motion, and explains the behavior of gases, including diffusion, pressure, and temperature.
