Quite easly really, a brain is just a very complex computer after all. The main difference is the brains functionalty is in the hardware, where as current computers work via the software a higher level of abstraction. Aka rather performing millions of very simple instructions to acheave something, the brains actual structure determins an outcome by the way an impulce travels through it. Aka a neural net. Computers can and have been built useing this principle. Working like an increibdly simplifed version of the human brain. Once quantom computing comes in to full swing computer technology will easly suppas are own abilty. Humans are programed in some ways, by are instricts, response pattens, defined by are inital brain strcuture, that structure changes through are life (actual phyiscal changes in positions of nurons etc)
Computers will eventaly be able to do the same, thus obtaining concusness.
Plus time is real? its a direction, like up or down, back or forward. Its just one of many in are 11 D universe, we just cant perseave of interact with most of them
Thus flying? and the technolgy does exist to grow you a pair of wings (although prohibited due to religion/ethical issues) so if you only define flying under your own power as flying you can do that to.
Actually, we aren't flying, we're just riding in things that fly.
Cheeper still, hire a large catapult.
