Infinity

The concept of Infinity is a subject that has no end. Something that is infinite is something that can continue in one direction forever. The concept of infinity is often seen in many subjects of arithmetic like Algebra and Physics. In astronomy, this is often seen in astro-physics. To the human mind, the universe is something that is infinite in terms of distance, mass, and the size of celestial bodies like galaxies. The universe itself is something that is thought up to be infinite since there is perhaps no boundaries to it.
