To say anything would spoil it.
...there may be just enough matter to close the cosmos and to trap us forever in an oscillating universe. If the cosmos is closed there’s a strange, haunting, evocative possibility, one of the most exquisite conjectures in science or religion. It’s entirely undemonstrated, it may never be proved, but it’s stirring:
Our entire universe, to the farthest galaxy, we are told, is no more than a closed electron in a far grander universe we can never see. That universe is only an elementary particle in another still greater universe and so on forever. Also, every electron in our universe, it is claimed, is an entire miniature cosmos containing galaxies and stars and life and electrons. Every one of those electrons contains a still smaller universe, an infinite regression up and down.
From Cosmos, by Carl Sagan:
Even if the universe isn't closed, couldn't our universe/cosmos still be an elementary particle in a larger cosmos? Just a particle that would presumably appear to be decaying in that larger cosmos?From Cosmos, by Carl Sagan:
