Cosmology and astrophysics are different but closely related disciplines. Cosmology deals specifically with the study of the origin of the universe, and the ongoing dynamics of the universe's development or evolution. In some respects then, cosmology may be considered somewhat of an overarching or parent discipline to astrophysics.
Astrophysics deals more specifically with the origin, classification and development of stars, which are part of the larger universe.
After the event in which our universe began, popularly called the "Big Bang", most scientists believe that space expanded rapidly, providing a place for the mass of the early universe to expand into. The universe cooled as it expanded, though it took some time before the early universe cooled down enough for atomic nuclei to form (big bang nucleogenesis). The initial mixture of atoms, mostly hydrogen and helium, provided the matter for the first or primordial stars.
So we see how cosmology precedes, chronologically at least, astrophysics, and is a necessary part of the knowledge of astrophysics.
Today astrophysicists and cosmologists study the expanding universe and the stars in it to see how they interact, and so the sciences of cosmology and astrophysics remain closely related and interact with each other.
So while it is not really possible to separate them completely, astronomy and astrophysics remain distinct sciences, but the knowledge of each one is necessary to inform the other.
What else can I help you with?
You want to know about the future of the universe you should study?
cosmology, which deals with the origin, evolution, and eventual fate of the universe. By studying topics such as dark energy, dark matter, and the expansion rate of the universe, cosmologists can make predictions about its future, including scenarios like the "Big Freeze" or the "Big Rip."
What is the scientific study of the universe?
Cosmology or astronomy are the scientific studies of the universe. Cosmology, is the study of the origin, evolution, and eventual fate of the universe. Astronomy is the study of celestial objects, the physics, chemistry, and evolution of such objects, and phenomena that originate outside the atmosphere of Earth.
Is the number of stars in the Milky Way Galaxy evidence in support of Big Bang Cosmology?
no the no. of stars in the milky way is not the evidence in support of the big bang cosmology.
What is the perfect cosmological theory?
There is no consensus on the perfect cosmological theory. The search for a theory that accurately describes the origin and evolution of the universe is an ongoing pursuit in astrophysics and cosmology. Theories such as the Big Bang theory and inflationary theory have provided significant insights, but there is still much that remains unknown.
What is the difference between big and large?
There is no difference; they are synonyms.
