Hello everyone I have a question I am not sure where to ask and I am not even sure what it would or might be called to search for it on the internet. It's simple really and has to do with string theory and the multiverse. For string theory and many other equations to work it requires extra dimensions all of which are "smaller" Quantum physics deals solely it seems with the small, the micro ect. But are there dimensions which are larger? What would a dimension outside our macro be called and do we have any representations or equations to express what that might be? Why is the 5th dimension smaller than our 4D spacetime? Thanks.
