Einstein said the universe is infinitely finite, with a boundary. Can this be explained?
That's fascinating. Can you tell me more about how this theory has been supported or challenged by scientific evidence?
There is actually a lot of debate among scientists about the validity of the closed universe concept. Some researchers believe that the concept is still a plausible explanation for the structure of the universe, while others have found evidence that suggests the universe may be open or even flat.
