I've been looking through this sub and some that are associated with it. I think I may have bleeding in my brain after reading some of those posts. Is there some story behind this or is it all nonsense? I'm so confused it hurts.

what property in substances cause light to speed up or slow down
How can light slow down then suddenly speed up. For example, if i send a beam of light through glass, it defracts at a certain angle and light slows down. Once it pass through the glass it speeds up. How does this occur? Shouldn't energy just be lost and not be regained?

why do businesses build skyscrapers in cities when it would be much cheaper to build their offices further out where land is cheaper?
I understand that in some places, space really is a limitation, but where in live in Perth, Australia for instance, it makes no sense to me why all these giant buildings are grouped together when it would be much more cost efficient to build wider, shorter buildings in cheaper areas.
