In a thought experiment from The Beginning of Infinity, the author introduces a universe traveling device. During a set interval, you hold the button you go from universe 1 to universe 2 for one minute then on to universe 3 for 30 seconds and so on until you release it and are taken back to universe 1. By the time two minutes is up, you will have traversed the infinite set of universes. If the instrument could take readings along the way, you have a way to measure infinity.
- If the universe is not infinite maybe this works because of non-trivial topology
- Using such a device you could jump to universality instantly because you could collect all information instantaneously

A universe that collapses to a single point due to baryon annihilation required to produce energy needed for colonization. The universe is not infinite and even though we observe the universe expansion accelerating, that doesn’t mean it will continue to accelerate forever. This is like the counterpoint of the Big Bang—the “Big Crunch”.
An experiment suggests that quantum processes (entanglement) might be used by brain functions which could explain memory performance and conscious awareness.
