The idea of a physical multiverse came later to modern science than it did to Hinduism. The concept that time is cyclical may sound strange to some, but it is true that it will happen over and over again. One hypothesis states that there is even the possibility of having the same Earth as ours and that the same events are happening there too, which means that you are experiencing this moment in another place, which may sound strange! But this is a possibility according to science and Vedic scriptures and even in other Universes, one could be living in the future or perhaps in the past.

For example, maybe you are experiencing a part of the Ramayan or Mahabharat or any other event from past history in some other universe at the same time as now. According to science, these possibilities may be there, but Hinduism believes that there is a multiverse in which things repeat themselves for ages and it is a cyclical and unstoppable process.
