Parallel Worlds

The book I read to research this post was Do Parallel Worlds Really Exist? by Shan Gao which is a good book but a bit complex and which I bought from kindle. This book contains many complex equations, but the gihist of the book is that there must be an infinite number of parallel worlds which means there is an infinite number of you and me's. This also means there is an infinite number of dimensions and types of matter. We already know of matter and antimatter. There is a story that if someone jumped in a time machine and went in time to when his grandfather was a boy and shot him dead. You might wonder how that could happen and for many years almost everyone thought time travel must be impossible for that very reason. Nowadays they think time travel will eventually be acheived but that you will travel into a parallel world. Also it would be impossible to travel to a time prior to the date the time machine was built. Which is why we don't see too many time travellers in the 21st century. I'll also tell you a theory that a psychic called Bernard had which was that when a star has a nova or supernova, that the pressure and heat are so great that a new universe is formed in another dimension. I think he's probably right. When you think of it time is influenced by gravity and the velocity of something. It's worth thinking about.
