I hope I posted this in the right place. I was thinking today, that since matter cannot be made, or removed from the universe, perhaps we are constantly expanding as well. Since the universe is constantly expanding, that must mean we must be expanding as well, since the universe cannot just make more matter as it expands. For all we know, we could be 10x bigger than we were yesterday, and never know it. This would explain black holes not being shaped as thought, but more of an hourglass, as matter goes in one end, and comes out the other in a different form. I know that Hawking has thought of that, but the first section is completely my idea. Please tell me what you think of this theory. Thanks.
