universe
The universe refers to all the things that exist, whether visible, or invisible. The objects in the universe can be divided into two main groups, namely living things and non-living things. Some scientists believe that the Universe begins with a massive explosion that creates space, time, energy, and matter. In the Universe there are very large galaxies known as the Great Groups, which are made up of smaller galaxies. In smaller groups of galaxies than the Great Groups, where we are known as Local Groups. There are 30 galaxies including the Milky Way that have been identified, circulating around the center of the local Group. In each of the galaxies it is estimated that there are 100,000 million stars and typically each gypsy-shaped and slightly thick middle is like a plate with a diameter of 100,000 light-years. However there are circular galaxies, barred circles, ellips, non-uniform forms.
