Yes, it obviously is, since people use it and you have heard of it.
It is used to prove some of the statements used in Einstein's The general Theory of relativity
Special relativity General relativity Photons as real entities, not just mathematical curiosities Heat capacity of low temperature solids Answer to the question, "Why is the sky blue?"
As real as any scientific theory. Cell theory, the theory of gravity, germ theory of disease, quantum theory and the theory of relativity are all theories that are well supported by the evidence and explain the phenomenon we observe in nature. The theory of evolution by natural selection is no longer " Darwin's theory ", but has been strengthened and added to in the 151 tears since Darwin and Wallace first proposed evolutionary theory.
Albert Einstein is not a pseudonym; it is his real name.
"Theory" in the "Theory of Evolution" phrase (and in any other similar phrase, like "theory of relativity") means that evolution is just something we suppose explains how world works, until we find a better way to explain things..."Theory" actually refers to the inherent inability of human to know the 'real' reality - or even if such 'real' reality exists (as the world of ideas of Plato).
Special theory of relativity: 1.The laws of physics are same for all observers in uniform motion relative to one another. 2. The speed of light is same ... Later Einstein proposed General relativity.

The universe was formed long time ago. Answer The Big Bang theory has estimates of about 13.7 billion years ago for the time of origin of the Universe. In other words, time (or Real time, if you distinguish between Real and Imaginary time - see Stephen Hawking's A Brief History of Time) began 13.7 billion years ago. In accord with General Relativity, space-time began 13.7 billion years ago. The beginning was a hot, dense, tiny singularity which expanded with explosive speed.
A doctrine, or scheme of things, which terminates in speculation or contemplation, without a view to practice; hypothesis; speculation., An exposition of the general or abstract principles of any science; as, the theory of music., The science, as distinguished from the art; as, the theory and practice of medicine., The philosophical explanation of phenomena, either physical or moral; as, Lavoisier's theory of combustion; Adam Smith's theory of moral sentiments.
Vulcanwas a small planet proposed to exist in an orbit between Mercury and the Sun. In an attempt to explain peculiarities of Mercury's orbit, in the 19th-century French mathematician Urbain Jean Joseph Le Verrier hypothesized that they were the result of another planet, which he named Vulcan. No such planet was ever found, and Mercury's orbit has now been explained by Albert Einstein's theory of general relativity
Chromosomes are not a theory they are real structures visable under the microscope.
