I always wondered about the stretching . If someone were to be pulled into a black hole , wouldn ' t the fabric of space time also be stretched , so there wouldn ' t be any noticeable difference between outsideinside from the person ' s perspective ? One very simple example that keeps coming to mind is in Futurama when Fry sits on the box containing their own universe and everything gets flatter . Since the universe is being flattened , would anything inside the universe be able to objectively notice that ? Kind of like how you can ' t directly perceive your distorted reflection through lab beakers without a mirror , technically you ' re being distorted but you can ' t tell . Is this anything like what happens with black holes ? I ' m a layman
