It's a great, big universe out there. In this section of Khan Academy, you'll learn about the brain-bending vastness of time and space.Unit 1: Scale of the universeStars, black holes and galaxies
Most cosmologists come from a Physics or Maths background, completing an undergraduate degree in one of these subjects before continuing on to research at a
Can machine learning be used in cosmology?
In this white paper, we summarize current and ongoing developments relating to the application of machine learning within cosmology and provide a set of recommendations aimed at maximizing the scientific impact of these burgeoning tools over the coming decade through both technical development as well as the fostering of emerging communities.

Cosmology at A Glance
Cosmologyis the discipline of science that studies the origin and eventual fate of the universe.
It is most closely related to the specific fields of astronomy and astrophysics, though the last century has also brought cosmology closely in line with key insights from particle physics.
In other words, we reach a fascinating realization:

General Relativity and The Big Bang
Newton's cosmology dominated science until the early twentieth century when Albert Einstein developed his theory of general relativity, which redefined the scientific understanding of gravity.
In Einstein's new formulation, gravity was caused by the bending of 4-dimensional spacetime in response to the presence of a massive object, such as a planet.

History of Cosmology
The study of cosmology is probably one of the oldest forms of speculative inquiry into nature, and it began at some point in history when an ancient human looked toward the heavens, asked questions such as the following:.
1) How did we come to be here?.
2) What is happening in the night sky?.
3) Are we alone in the universe?.
4) What are those shiny th.

Mysteries of Modern Cosmology
Though cosmology has advanced much over the last century, there are still several open mysteries.
In fact, two of the central mysteries in modern physics are the dominant problems in cosmology and astrophysics:.
1) Dark Matter - Some galaxies are moving in a way that cannot be fully explained based on the amount of matter that is observed within the.

Origins of The Universe
It is worth noting that the big bang theory actually describes the way the universe has evolved since shortly after its creation, but cannot give any direct information about the actual origins of the universe.
This isn't to say that physics can tell us nothing about the origins of the universe.
When physicists explore the smallest scale of space, .

What makes cosmology different from other science?
However, there are two main issues that make the philosophy of cosmology unlike that of any other science.
The first is, The uniqueness of the Universe:
there exists only one universe so there is nothing else similar to compare it with and the idea of “Laws of the universe” hardly makes sense.
Han learning, or the Han school of classical philology, was an intellectual movement that reached its height in the middle of the Qing dynasty (1644–1912) in China.
The focus of the movement was to reject neo-Confucianism in order to return to a study of the original Confucian texts.
