What is the difference between space and universe? It seems to be a very difficult question to answer and even understand the difference between them. Space is considered to be wider as compared to the universe. There have been many people who have expressed their thoughts on space and universe. The universe is believed to have born with a big bang which is referred to as a dense point. It just cannot be counted as to how old our universe is. The universe has been expanding gradually and this expansion is faster even than the speed of light. The universe has almost doubled in its size and is 100 times bigger now than what is was before. This burst of expansion is called as inflation. After the inflation the universe grew at a slower rate. This led to the expansion in the space. As a matter of fact the universe began to cool and matter was formed.
The universe is filled with a number of objects which are named as photons, electrons, protons, neutrons and anti-electrons. The universe was very hot. This heat resulted in breaking smashed atoms with huge forces. These broken pieces scattered all around the universe. They became dense just like the fog. It took more than three lakh years for the matter to cool down and atoms to form. There was a new form of energy discovered known as dark energy which characterized the universe. The universe began to slow down gradually when the dark energy was discovered. This phenomenon gave birth to the solar system. Then there were stars, galaxies and many other objects discovered in the space.
Space and universe is a very wide and interesting concept to study. There are many heavenly bodies that our universe comprises of. One can go on and on exploring them and learning. The National Aeronautics and Space Administration has been exploring such bodies and launching new programs.
