In physics matter is regarded as anything that has mass and occupies space. Matter can either be formed from particles of same or different kinds. Elements are those substances that are formed from particles of the same kinds, while compound are formed from particles of different kinds.
Compounds and elements are formed of smaller particles referred to as atoms which are regarded as the smallest particle of an element that cannot be spilt into smaller particles. An atom is mainly composed of a nucleus that consists of positive charges particles known as protons and neutral charges referred to as neutrons.
The nucleus is centrally located and is usually surrounded by a cloud of negatively charged particles known as electrons. The size of an atom is not well defined and is often measured in terms of the size of its diameter which is considered to be approximately 10-10 meters (Williamson, 2008).
Normally, the radius of observable universe is considered to be approximately 1028 centimeters. However, the size of the observable universe is not given in terms of the size of the radius of the observable radius. Instead its size is given in terms of the difference between the smallest and the biggest units.
The smallest possible unit in the observable universe is considered to be about 10-33 centimeters. Thus, the size of the observable universe is 1061 centimeters which is the distance between the smallest and the largest possible unit.
The Hubble Ultra- Deep Field is considered to be an image of a small region of space in constellation Fornax that is combined to Hubble Space Telescope data that was collected in the period between September 24, 2003 and January 16, 2004.
The image is regarded to be the deepest image of the universe that has ever been taken. The image reflects back to about 400 and 800 years back after the Big Bang. The Hubble Ultra- Deep Field is normally used to locate galaxies that existed during these eras.
The image was captured in a part of the sky that had “a low density of bright stars in the near-field” that made sure that the image formed had a better vision of dimmer as well as more distant objects (Kuhn, 2010) It is believed that the image has over 10,000 galaxies. In 2009 between August and September a more refined image was generated by using a more advanced Wide Field Camera.
The modification enabled the astronomers to identify a new list of prospective distant objects. Some of the objects spotted include southern-hemisphere constellation Fornax which is an image that is approximately 3 arc minutes across. The image is normally smaller than 1mm by 1mm squire of paper when it is held at a distant of one meter away.
A multiverse is considered to be a set of probable hypothetical universes that forms the physical reality. The diverse universes contained in a multiverse are regarded as parallel universes. It is noted that multiverses have greatly been hypothesized in physics, cosmology, fiction, philosophy, theology and more specifically in science, fiction and fantasy.
Multiverse hypothesis in physics is of the opinion that there are extra universes other than the ones that we are aware of. It also goes ahead to offer taxonomical data with regards to parallel universes which are structured in various levels (Kuhn, 2010). This notion has enabled many scientist come up with various theories that try to explain about multiverse.
