For the same reason that you already get excited whenever you do something spectacular. Just because someone else has done it - doesn’t matter if they look, talk, and act just like you, they’re separate entities - doesn’t diminish the accomplishment of YOU doing it.
For example, just a few weeks ago, my buddy got excited because he shot down a fly in midair with a rubber band. I can guarantee you that someone else in history has done this… does this mean he shouldn’t have gotten excited? Of course not… because HE has never done it before, and THAT’S what was so exciting to him.
The difference, JThunder, is that if certain fundamental physical constants were different, intelligent observers would not exist. Based on the mere fact that we are observers, we can conclude that the laws of physics must be such that observers can exist.
Thus, if there are multiple universes, every single observer in every universe will see that the universe is set up in a way that allows observers to exist. Therefore this idea can be used to genuinely and completely explain any fact necessary for observers to exist.
This is the use of the anthropic principle; specifically, the weak anthropic principle. This same reasoning does not apply to any more restricted case.
I’m not saying that infinite universes would eliminate emotional responses to events in the view of one observer. They wouldn’t (except for the universes where emotions don’t exist, I guess). But, getting excited over something would be completely pointless, when taken in the larger context of the ‘multi-infi-verse.’(After thinking about this a bit I realize that this is resting on the assumption that events in our universe actual posess some real value/meaning aside from what humans attach to them). To me, infinite universes would spit in the face of the human ego. However, I’m not sure if that’s a good or bad thing.
Yes, but that sort of viewpoint has the same scope as one that says everything we do is pointless because in a billion years we won’t even exist.
To me, ONE universe spits in the face of the human ego. Hell, a single GALAXY spits in the face of the human ego. We’re tiny, insignificant specks of useless nothing in the grand scheme of things… multiple universes would just make the scheme just a little bit grander.
