Maybe people who are more knowledgeable than me can help me with something that's been bugging me:
If there are multiple spatial dimensions beyond what we can see, why does it look to us like conservation of energy is obeyed?
I mean, we can't measure kinetic energy of things moving along axes we can't observe, so when a form of energy we can observe (say kinetic energy of movement along an axis we can see) is converted or redirected into kinetic energy we can't measure, it would appear to us that the energy is just being lost.
So what gives? Why do we have physicists saying both that conservation of energy is obeyed in our three spatial dimensions AND that other spatial dimensions exist that we can't see?
