If black holes exist , then space-time can be compressed !
If the metric expansion of our universe is really happening then space -time can be stretched !
If the above statements are true, then space-time separations are actually variables, meaning that space time invariance shouldn't be true, but the speed of light being a constant for all observers regardless off their own velocity through space-time disproves that.
Where does the fact that the faster an observer traverses space-time the less time they will experience, fit into this seeming can of worms? I really would like to exchange notes on this topic , if anyone is interested in doing so.
