What is a multiverse theory

This is the modern era of science and technology. We can do anything from it. We have discovered a lot of the things from the science. So the burning issue or the topic is on multiverse theory. According to which it says that the universe is infinite and we don't know its actual size. In this universe it is supposed that there are many universe. According to Albert Einstein have considered this space as a fabric, and this is a kind to where we are living. There are considered to be many universe that forms many layers from the top of the earth at its end. In the same way according to the inflation theory the universe started from a small point and from there it then begins to expand at a constant rate. The universe that we see today has originated from a small point. For this we can take a example of a balloon if we put the two dot on the balloon and expand it then the dot will go more further and further away.
        Many scientist claims for the reality or the existence for the multiverse theory. It says that the earth is not alone but it too has many more members. Whereas it is written as the hypothetical theories having infinite possibilities. It too has some of the evidence to make believe on it. The anomalies on the cosmic background radiation is the first evidence that proves that the other universe might have given pull to the earth. Whereas the more technical satellite prove no any gravitational pull by other universe so it speaks on the impossibility of multiverse theory. However all those facts also today the most of the scientist are giving their excellence effort for the finding of the parallel universe. The parallel universe might not be only hypothetical because it was also accepted by most of the scientist of the past. If this is prove to be possible then in another world we can find the similar kind of us.
     So hope this topic will soon bring a fruitful result for the future.
