Cosmology today

Cosmology is the study of the beginnings, formation, and evolution of our Universe. In today’s context it is in a badly confused state. Right now, we have no idea as to what makes up 99% of the Universe. This, needless to say, is very embarrassing. Although much of what is visible (physical matter) in the Universe is becoming comprehensible, with great recent strides in understanding star formation, galactic structure, and spectacular events such as supernovae, it would appear that there is another component of the universe - possibly making up most of its mass - which we cannot see, and we do not understand; DARK MATTER.

This subject has been around for sometime. Lots of speculations and references. So much so that it has found its ways into the a crappy X-Files episode. We need to find the real answer to this dilemma. Or do we have to wait for another Einstein to come along?

What is it really? How do we know of its existence? And how do we know it is really ‘dark’? In the coming days, I do not have answers, but will try to come up with some thing that will be within the boundaries of physics and its laws as we know it at present. Please feel free to comment.
