Universe

Universe is the full collection of everything including stars(stars are ball of hot gases on outer space),star systems( a structure which is a collection of stars, possibly even a galaxy),galaxies( a similar structure like star system but(possibly larger) and our galaxy is called Milky Way and our neighboring galaxy is Andromeda ),solar systems( a structure which is a collection of planets which are cold ball of solid matter, unlike stars, which are hot ball of gas matter),planets(as said before are cold ball of soild matter),local groups( a group of galaxies, which is about 30 to more in number),superclusters( a larger groups of galaxies and even local groups of galaxies, about 100,000 - more in numbers possibly),clusters(a larger but smaller than supercluster group of galaxies about less than hundreds of thousands in numbers),matter and energy ( matter means everything touchable and seeable in the universe and is also defines to solid, liquid and gas and is made up of atoms and energy means the capability of working or doing something but in a wide range of forms and also has a wide range of form including chemical,etc.),life( things that are living and is moving and is the state of living and if something has life it means it is living and/or has the probability and the nesscary things needed for a living thing to live),all of space and time and the observable universe which we can estimate and observe and has being known to have about 2,000,000,000,000 or 2 trillion galaxies according to recent studies on 2016  and is 93,000,000,000 or 93 billion light years  in size and 10,000,000,000,000,000,000 or 10 quintillion stars in number and over trillions of planets and lots of solar systems and star systems and hundreds of millions  of if not billions of local groups,clusters and superclusters. And would possibly change one day at any year in the future
