Einstein's STOR states that if I was in an upward accelerating elevator I would not be able to tell if the weight I would be experiencing was due to acceleration or gravity from my frame of reference. This identical appearance idea work for expansion also?
It has been stated many times that the expansion of the universe is not as a result of an 'explosion' at the big bang but rather an expansion of space/time.
My question is how could you tell? Expansion and an explosive event are both theories, the former more accepted than the latter. How would the two look different? How can you prove JUST by observation that what you are looking at is one or the other since the results would look the same (I'm assuming)? Wouldn't the continuously increasing distance between objects occur in either case? Wouldn't the impression that every object is moving away from our vantage point be the same. Wouldn't the dots on the balloon analogy work in either case?
