If we create nanites that can attach themselves to and read/write to neurons we can do many things like connect brains to the internet, mind control/puppeteer people, connect everyone's brains together into a superbrain, create robot copies of people by mapping their nervous system (the soul is in the belly, so in order to actually *transfer* a person to a robot body you would have to do something like spray the belly with self-replicating flesh-eating synthetic cells). Also, and this is the less believable part, you may know about quantum entanglement, a process in which quantum particles can influence each other's motion across vast distances of space (and according to my hypothesis, time). The communication between these particles happens faster than light, which leads me to believe that it occurs through portals, that is, zero-distance gateways between otherwise distant points in space or time. It's proven that mothers can sometimes feel it when something happens to their kids from far away, and identical twins get sick at the same time even on opposite sides of the world. I've seen lots of evidence of *unconscious* (that is, not conscious, can't stress this enough) telepathic communication between humans and other species. This leads me to believe that everything can communicate via portals. So, to time- or space-travel, all you have to do is entangle an empty area of space (like putting your finger between two pages of a book) (space as in room, emptiness, nothing there) with another area of space, then use the very entanglement phenomenon to entangle with the portal, which should be able to be entangled with since this applies to every phenomenon in existence, and should be able to be manipulated by routing energy through other portals (through its key manipulation points like human nerves), then simply widen the portal so a person or vehicle or anything could pass through. If you create a simulation of total chaos (not randomness, because randomness is never
