    Science expert Emerald Robinson explains what is the Cosmos.

    Emerald Robinson: Hi! My name is Emerald Robinson and in this What Is Video, we are going ask a question what is the Cosmos? To some, the Cosmos is synonym for the Universe. However, many scientists think that theyre important differences between the Cosmos and the Universe. The term Cosmos was first used by the Greek Mathematician and philosopher Pythagoras. To mean the order of the creation, the other disorder part he called Chaos, because of this emphasis on order physicist currently defined the Cosmos as everything that follow scientific law, such as the laws of motion or the laws of thermodynamics. According to the same definition the Cosmos is larger in scope than the Universe. Scientists believe the Universe began about 13.

    7 Billion years ago with the Big Bang. Therefore, science also assumes that will have an end. The Cosmos in contrast is infinite, i.

    e. it doesnt have a beginning worn end and that also means it's a term big enough to encompass things we are only starting to understand. For example; the Cosmos allows for the concept of the Multiverse, the theory that there are multiple universes. This is an area hot debate in the Physics commodity, but some Physicists think that there is evidence that shows there may be been more than one Big Bang and therefore, more than one Universe.

    Scientist who studied the Cosmos are called Cosmologist. This branch of physics tends to be theory based and relies on math to model and predict things we cant see. This sets it apart from Astronomy which depends on observations as evidence. For house the most famous definition of the Cosmos comes from Astronomer, Astrophysics and Author Carl Sagan, who said that the Cosmos is all there is, all there was, all there ever will be.
