The sun was now low beneath the horizon. Darkness spread rapidly. None of my selves could see anything beyond the tapering light of our headlamps on the hedge. I summoned them together. "Now," I said, "comes the season of making up our accounts. Now we have got to collect ourselves; we have got to be one self. Nothing is to be seen any more, except one wedge of road and bank which our lights repeat incessantly. We are perfectly provided for. We are warmly wrapped in a rug; we are protected from wind and rain. We are alone. Now is the time of reckoning. Now I, who preside over the company, am going to arrange in order the trophies which we have all brought in. Let me see; there was a great deal of beauty brought in to-day: farmhouses; cliffs standing out to sea; marbled fields; mottled fields; red feathered skies; all that. Also there was disappearance and the death of the individual. The vanishing road and the window lit for a second and then dark. And then there was the sudden dancing light, that was hung in the future. What we have made then to-day," I said, "is this: that beauty; death of the individual; and the future. Look, I will make a little figure for your satisfaction; here he comes. Does this little figure advancing through beauty, through death, to the economical, powerful and efficient future when houses will be cleansed by a puff of hot wind satisfy you? Look at him; there on my knee." We sat and looked at the figure we had made that day. Great sheer slabs of rock, tree tufted, surrounded him. He was for a second very, very solemn. Indeed it seemed as if the reality of things were displayed there on the rug. A violent thrill ran through us; as if a charge of electricity had entered in to us. We cried out together: "Yes, yes," as if affirming something, in a moment of recognition.
The oscillating universe theory—that the universe will end in a collapse or ' big crunch ' followed by another big bang, and so on—dates from 1930. Cosmologists such as professor Alexander Vilenkin from Tufts University  and Massachusetts Institute of Technology professor Max Tegmark suggest that if space is sufficiently large and uniform, or infinite as some theories suggest, and if quantum theory is true such that there is only a finite number of configurations within a finite volume possible, due to Heisenberg's uncertainty principle , then identical instances of the history of Earth's entire Hubble volume occur every so often, simply by chance . Tegmark calculates that our nearest so-called doppelgänger , is 10 10 115 meters away from us (a double exponential function larger than a googolplex ).    In principle, it would be impossible to scientifically verify an identical Hubble volume. However, it does follow as a fairly straightforward consequence from otherwise unrelated scientific observations and theories. Tegmark suggests that statistical analyses exploiting the anthropic principle provide an opportunity to test multiverse theories in some cases. Generally, science would consider a multiverse theory that posits neither a common point of causation, nor the possibility of interaction between universes, to be an ideal speculation. However, it is a fundamental assumption of cosmology that the universe continues to exist beyond the scope of the observable universe , and that the distribution of matter is everywhere the same at such a large scale (see cosmological principle ).
