I have to ask, comparatively to what? I think I understand what you mean, but I do not believe that the totality of the universe exists. The universe exists only in our mind as a unity, as a thing. The idea “Totality of Mass” is a construct, it requires a human mind. Any supposed totality is a product of our will to understand, which one could interpret as our will to power. So the larger the totality that rolls out of our computers, the more reason we have to pat each other on the back and exchange compliments for our creative efforts.
Outside of our efforts to understand in this way, who knows if such a thing as te universe even exists at all? If it does, it certainly would exist in a as vastly different shape, or number of shapes than what we are able to imagine. Have we evolved to comprehend the whole we are part of? That would be a very fortunate circumstance, and very strange. But it’s possible. Still, such a whole would only be what we can conceive of. I see no possibility for any of our notions of totality to pertain to an objectively existing limit.
In terms of objective relation (size, quantity), it may be exiting to see the numbers we can come up with. But we cannot possibly so more than interpret limits into what our senses equip us to interpret. Since it is a matter of interpretation and nothing besides, the only way in which these notions we come up with are relevant to us, is in how they affect us.
That is why I’ve aways admire the space-program, and why I hope that man will attempt to set foot on Mars, and on the moons of the gas-giants beyond. It is such an inspired activity. Useless perhaps (although some interesting resources have been located on Mars) but only the miser cares first about utility.
