Every possible outcome occurs, so while I may have chosen alternative A, in another of the many worlds I have chosen B. Every possible choice has to be made, so the universe creates as many of 'me' as necessary to fulfill all paths.<br /><br />On the bright side, everyone is immortal in the many worlds. People don't just die, they die for a reason. So as long as there is an alternative where it is possible you don't die, there is a 'you' to fulfill that branch. <br />Larry Lennhoffhttps://www.blogger.com/profile/06578073969473815180noreply@blogger.comtag:blogger.com,1999:blog-36951752.post-62590741632368835972019-07-18T10:27:57.254-04:002019-07-18T10:27:57.254-04:00Here's my Ode that I might have earlier posted...Here's my Ode that I might have earlier posted in a comment at this Blog:<br /><br />***<br /><br />MULTI-VERSES ON MULTIVERSES<br /> <br />There is no edge to our universe<br />As it expands, continues in infinity.<br />But what if there is a curse<br />Of multiverses with interstellar diversity?<br /><br />Each with its own “Big Bang” birth<br />Of differing magnitudes,<br />With planets like our own earth<br />Peopled with conflicting attitudes.<br /><br />Might they all function universally<br />Or each taking its own course<br />Competitively, independently<br />Each with its own forms of force?<br /><br />Universe versus universe,<br />With their own clashing gravities,<br />Or forces even worse,<br />Like Spaceballs* banalities.<br /><br /> April 3, 2015<br /><br />*For variation, substitute “Star Drek”.<br /><br />***<br /><br />When it comes to infinity, I am pi-eyed.

Without this assumption, it is possible for a single choice to affect the entire infinite universe at once, which breaks these ideas.)<br /><br />If I assume finite time then I think there's a relatively simple solution to the infinite universe utility maximization problem.<br /><br />For any choice, the highest utility action in the universe is the one that:<br /><br />Define a finite set of the universe such that:<br /><br />1.) All utility effects of the choice are included in that finite portion of the infinite universe.<br />2.) All areas of the infinite universe outside that finite portion are unaffected by the choice.<br /><br />Given that set, the highest utility choice is the one that maximizes utility within that finite portion of the universe, since the remainder of the universe is unaffected.<br /><br />This has the added bonus of being basically what we mean when we say maximizing utility, since at some point the scope of a choice is beyond our ability to measure, and thus we usually discount those effects.<br /><br />Getting back to infinite time:<br />Infinite time creates a problem because with infinite time, it's possible that some choice has an infinite effect on utility. This brings in a larger problem, but I think we can use a similar trick. I'll also assume that utility has a time component, and thus can be integrated over time. There may be other ways to measure a time-based utility, but I will use integration.<br /><br />Given that utility over time is integrable, then I would define the highest utility choice in an infinite universe as:<br />The highest utility choice in an infinite universe with infinite time is the choice such that for some time t, the integral of all utility effects of that choice over time between when the choice is made and all finite times greater than or equal to t, the net utility effect over the previously defined finite portion of the universe affected is greatest.<br /><br />Now, it's possible that some choices will have a sinusoidal effect on utility over time, such that there is no such time t after which one choice is always better. In this case it may not be possible to define a "best" choice in a utilitarian way in even a finite universe that has infinite time. This is why I consider infinite time to be so much bigger of a problem than infinite space.Greghttps://www.blogger.com/profile/13863666766346294969noreply@blogger.com
