Cosmology
Cosmology - the study of the beginnings, formation, and
evolution of our Universe - is currently in a badly confused state. At
the moment, scientists don't know what makes up 99% of the Universe.
This,
needless to say, is a rather embarrassing situation. Although much of
what
is visible 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. References to this `Dark Matter' have
been
circulating the popular science presses for over a decade now, and even
found its way into a really bad episode of the X-files. What is it,
really?
How do we know that it's there? How do we `see' it if it's `dark'?
Here,
I'll try to answer those questions, and explain what my research is
about.
I hope that this will be educational and fun; Java applets will be used
so that you can see what I'm talking about, and I'll do my best to
avoid
unneccesary jargon
