Astronomy compels the soul to look upwards and leads us from this world to another.

Cosmology

Cosmology is the study of the origin, evolution, structure, dynamics, and ultimate fate of the universe as well as the natural laws that keep it in order. It also includes the study of the nature of the Universe on its very largest scales.

 

Cosmic Scale Factor
19th May 2009Cosmology
Cosmic Scale Factor is a function of time which represents the relative expansion of the universe. It relates the comoving distances for an expanding universe with the distances at a reference time arbitrarily taken to be the present.
Cosmic Microwave Background Radiation
19th May 2009Cosmology
The Cosmic Microwave Background Radiation (CMBR) or Cosmic Background Radiation (CBR) is the afterglow from the early universe and provides strong evidence for the theory of a hot Big Bang. This article looks at what the CBR is, how it was detected and why it is important for cosmology.
The Importance of CBR in Modern Cosmology
1st December 2008Cosmology
The Cosmic Background Radiation is the afterglow from the early universe and provides strong evidence for the theory of a Hot Big Bang. We take a look at what the CBR is, how it was detected and why it is important for cosmology.
Black Holes
16th November 2008Cosmology
A black hole is a region of space that has so much mass concentrated in a small area that there is no way for a nearby object to escape its gravitational pull.
The Nature of Light
5th October 2008Cosmology
Physically, light (including X-rays, ultraviolet, visible light, infrared, radio) is an electromagnetic wave and always appears in the form of finite quanta, photons. But what do these terms mean?
The Four Forces in the Universe
30th September 2008Cosmology
Despite the complexity of the universe, all matter is made up of a limited number of particles, and the way in which these particles interact with one another can be reduced to no more than four distinct interactions.
The Expansion of the Universe
28th September 2008Cosmology
Edwin Hubble made the observations in 1925 and was the first to prove that the universe is expanding. He proved that there is a direct relationship between the speeds of distant galaxies and their distances from Earth. This is now known as Hubble's Law.
The Physics Governing the Universe
22nd September 2008Cosmology
In this article, we will have a look at some of the important physics concepts needed to understand how the universe works.
