Best Answer

The universe is the totality of intelligible, perceptible, and quantifiable reality that is the focus of human scientific research. It is a four-dimensional space-time continuum consisting of matter, energy, and forces. The universe consists of both inanimate matter (e.g. planets, stars, galaxies, asteroids, comets) and animate matter (e.g. plants, animals, humans, bacteria, fungi). The four fundamental forces in the universe are gravitation, electromagnetism, and the strong and weak nuclear forces.

OR: The universe is everything, or the universe is everything around here -- thus, some talk about other universes. Sometimes the other universes are separated by distance, sometimes by time, sometimes by other imaginary conditions. The universe of real numbers does not include the square root of negative one -- another use of the word universe.

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.


What language did people have to understand the universe?

They need a deep knowledge of astronomy, cosmology, physics, mathematics, chemistry.


What is the study of life in the universe?

You are probably going for the term cosmology, which is the study of the universe as it is now. This study includes all of the mass of the universe, but not in the sense of focusing on the study of individual things on the micro level. Cosmology can deals with theories of the development and possible end of the universe. The technical term for the study of the origins of the universe is cosmogony, although informally the term cosmology covers this as well.Answer:The universe is composed of matter and energy. Physics is the science of matter and energy and of interactions between the two, grouped in traditional fields such as acoustics, optics, mechanics, thermodynamics, and electromagnetism, as well as in modern extensions including atomic and nuclear physics, cryogenics, solid-state physics, particle physics, and plasma physics.


How is astronomy defined?

Astronomy is a branch of physics investigating celestial bodies and phenomena.


What should you have to do to be a cosmologist?

Study physics, mathematics, and astronomy in undergraduate college. Specialize in cosmology in graduate studies.

Should you choose Astronomy or Cosmology as a career?

Depends if you are interested in observing or theorising about the Universe. Astronomy requires a good knowledge of ALL sciences whereas cosmology requires a heavy knowledge of physics and all other sciences. Best to start with astronomy and move into cosmology, astrophysics, theoretical physics if you have the aptitude.

What kind of science is space?

astronomy is space exploration and cosmology it physics in space.


How can ''astronomy'' be defined?

According to the Oxford Dictionary, astronomy is defined a the branch of science that deals with celestial objects, space, and the physical universe as a whole. In other words, astronomy deals with all bodies in space (such as stars, planets, galaxies, etc.), and basically the entire universe. There are many different branches of astronomy such as astrophysics (deals with the physics of the universe) or planetary science (deals with our local Solar System).

What has the author D W Sciama written?

Dennis William Sciama was a British physicist known for his work in general relativity, astrophysics, and theoretical physics. Some of his important contributions include research on cosmology, black holes, and the thermodynamics of the universe. He also mentored a number of prominent physicists, including Stephen Hawking.


What makes up the walls of the universe?

If the universe has walls, we don't know anything about them yet, because we've never yet been able to see far enough to spot them. However, you should be aware that all of the best current work in astronomy, cosmology, physics, and also western religion I think, agrees that the universe doesn't have any walls.
