Where did all the energy in the universe come from? This is not physics, it’s methaphysics. We are talking about things that are outside our knowledge and science is descriptive, not prescriptive. Extrapolations must be tested. This is not much different from saying that the most remote galaxies receding at speeds faster than light is impossible, because nothing can travel faster than light. Maybe it’s just matter that can’t break that rule, while space itself can expand at whatever speed, or maybe it’s just an error somewhere in our assumptions. We still don’t know. But we DO think they are receding faster than light.
That’s not a very good example I don’t think. I’m no cosmologist, but my understanding is that we know pretty well that distant celestial objects are moving away from us faster than the speed of light. Special relativity doesn’t really say anything about non local objects, and the expansion of space does not violate locality. No information is being transmitted faster than the speed of light. The medium through which light is traveling is changing. It’s not some big unsolved mystery.
