Most generally, someone who studies the universe is an astronomer. If you are thinking specifically about the ideas about how it all evolved, then you'd say a cosmologist.
A person who studies planets and galaxies is called an astronomer. Astronomers observe and analyze celestial bodies such as planets, stars, and galaxies to understand their composition, behavior, and evolution. They use telescopes and other instruments to gather data and make scientific discoveries about the universe.
a person that studies gems is called a gemologist.
A person who studies animals is called a zoologist.
A person who studies the earth is called a geologist.
A botanist is a person who studies plants.

A person who studies physics is known as a physicist. Physicists explore the fundamental principles governing the behavior of matter and energy in the universe, using mathematical models and experimental methods to understand and predict physical phenomena. They may specialize in various subfields such as astrophysics, quantum mechanics, or thermodynamics.
A person who studies sand is known as a psammologist.
A physicist is a person who studies physics. The study of Physics is the study of the motion and behavior of all known objects and energy in the universe. A physicist studies physics. Physics is the science of modelling the universe around us in an attempt to understand the universe, and to predict its behavior, by examining and manipulating the model. The term "Physicist" was coined by English philosopher, priest, and historian of science William Whewell in 1840, to denote a cultivator of physics. There are a variety of branches of physics from studies in sub-atomic particles to studies of the behavior of the material of the universe as a whole.
A person who studies space is called an astronomer. They observe and analyze celestial bodies such as planets, stars, and galaxies to better understand the universe.
A person who studies jewelry is known as a gemologist or a jewelry historian, depending on their focus.
A person who studies bird is a ornithologist
