The edge of the observable universe is not because of that.
It is because space expands. Therefore everything goes away from everything else. Therefore, everything goes away from us. And the more space there is between us and that other thing, the more space expands, since there is more space. Therefore, things that are farther away from us, get away from us faster than everything else. Only if it is close enough to us that gravity is strong enough would that something not move away from us.
This creates a peculiar situation. Things that are far enough away from us, actually move away from us faster than the speed of light. This means that no photon ever emitted from this far away will ever reach us.
That is the edge of the observable universe. The distance at which a photon emitted in our direction will never reach us, since for every meter the photon travels, there is at least a meter of space "created" between us. Therefore it never progresses in moving towards us, in fact, it moves away from us even though it is traveling in our direction.
This is actually true though. Basically every country has done it.
If printing money results in enough value created, there is no inflation.
Of course, you have to create a lot of value per money printed, which no country has achieved. And that's where taxes come in and fill the gap.
Many of the "economic miracles" involved printing a lot of money. But since their value output increased so fast, (and again, taxes) they experienced little inflation.
It is theoretically possible to print money without taxes and not have inflation. That would be more than a miracle though. If you get even more efficient with money, even deflation would happen.
It's the same reasoning behind debt. Debt is "bad" because you have to pay more than what you were paid. But if you are smart with that money and create more money from it, you can pay back the debt (including interests) and get some extra money for yourself.
