Question

what is parallel world ? parallel universe does it exist as shown in spider man into spider verse ?​

Answer 1

Parallel universe is a theory at present

It is believed that some billion light years away and inside some black holes there exists a universe which is similar to that of ours.

It is considered to be parallel because it reflects what happens here.

Since there is expected to be another universe multiverse theory is also proposed

Answer 2

Parallel universe (in multiverse) or parallel world are a hypothetical self co-existing contained reality which shows similar characteristics with our planet earth although different in fundamental activities (QUANTUM THEORY).... according to Stephen Hawking and Einstein... parallel universe does exist.....and there might be millions of planets just like earth in other universes...obviously no one can know about them and there is no solid proof about them.... but there is also no debate that it might not happen..... living in earth we often feel that there is no such other planet other than earth which has life in it...but we might be wrong in our way of thinking.. isn't it?..... According to Stephen Hawking one can reach parallel universe through black holes... although the statement remains a mystery and still unverified.....YOU CAN WATCH INFORMATIVE VEDIOS ON PARALLEL UNIVERSE IN THE FOLLOWING YOUTUBE CHANNELS:-

hope I cleared a part of your quest.....
