Bashar ( bashar.org ) channeled by Darryl Anka these last 30-odd years, answered the question,
"Is there more than one Universe ?", thus:-
"More than you have numbers to count !"
The next question was,
"Do these other Universes have the same laws of Physics that we have ?"
Came the response,
"No, but we are not going to go into that, as the whole subject is exquisitely complex and you are not equipped to understand any part of it at this time.
However, there are 5 Laws that pertain to all Universes, everywhere and everywhen. Would you like to hear about those ?"
Needless to say, the answer was enthusiastically in the affirmative !
"Very well, here they are:-
Law No. 1 - You Exist (Eternally, - not much you can do about that !)
Law No. 2 - The One is the All and the All are the One (Unity Consciousness)
Law No. 3 - It is always Here and Now (Never not - have you noticed ?)
Law No. 4 - What you focus upon increases (Law of Attraction)
Law No. 5 - Everything changes, except the previous four Laws (Expansion)"
