I believe that our universe is infinite in time. And one of our destinies is to create our own universes that are infinite in time.
Moreover, according to some strange logic, nested universes can be bigger on the inside than on the outside.
Suppose we want to create a smart-contract-universe with the ability to infinitely nest nested universes within it.
The number of elementary particles in the Universe ($10^{80}$) is greater than the number of bits in the memory of a single EVM smart contract ($3 \times 10^{79}$) by only about three times. This means that in our strange logic, our smart-contract-universe is only three times smaller than real reality.
However, inside a single smart contract (let's call it level zero), there can be references to the nested addresses of level-one smart-contract-universes. As a result, in our strange logic, the memory of our smart contract grows by a factor of $2^{160}$, which means our blockchain universe becomes larger than our reality by a factor of $4.38 \times 10^{47}$ (that is four hundred thirty-eight septillion) times.
And if level-one contracts start making their own nested universes — level 2, 3, and so on to infinity — then eventually we get nested multiverses of infinite size.
Of course, skeptics and pessimists will say that this is only potential memory, and if you try to fill all of it, there won't be enough atoms in the universe.
But I would reply to that by saying that our universe is very strange too. Due to the quantum nature of matter, the observer effect, and various other theories, I can similarly say that not all atoms of our universe actually take up space on an... external hard drive, let's call it that. Modern fundamental physics says precisely this: our reality works exactly like sparse storage and lazy evaluation.
It is entirely possible that we too do not have access to all the memory and computations of the universe. This is probably one of the explanations for the Fermi paradox. Perhaps we are generally in an isolated flask, and everything telescopes see is a hologram on an outer sphere.
There are games, like No Man's Sky, where the cosmos is huge. But I haven't seen a game yet where space is not just big, but infinite. And blockchain will give this idea reliability — nobody would want to build something infinite on a centralized server.
This thought, that we can create internal universes that are bigger on the inside than on the outside, inspires me deeply!
Later on, we can think about who is going to pay for this whole infinite banquet and how to compress data inside to make it cheaper, but that's not for today.
