This document gives a brief insight into the possibility of time travel but not in the sense that most would expect. It looks at the big bang, which is theorised to have formed the expanding cosmos and at the same time looks at the cause of the big bang set in the dim distant future. It also reviews the spectral red shift and its erroneous use for measuring vast distance and direction and meets conjecture on the even level of cosmic radiation in the cosmos.

A telescope can help us in studying far-away matter of the vast space out there in our universe. Hubble telescope is one such gigantic telescope that offers us a look at diverse parts of the universe aside from ours. Telescopes are essentially of the reflecting and refracting types and the magnification make far off objects visible.

The Telescope turns 400 years old this year and in four century period astronomers and telescope makers have been continually making larger and larger telescopes in order to peer deeper and deeper into the mysteries of the universe. There are currently quite a few enormous instruments in use and there are several next generation telescopes being developed that will dwarf anything currently in use. This article takes a look at some of these magnificent monsters of astronomy.
