Multiple Worlds Interpretation. One need not accept this interpretation as reality to recognize that some of the ideas are relevant to the abortion debate. There need only be one world and to me, it is mind blowing to think of how the universe turns out if just one little thing goes a different direction. Personally, it was the presentation of MWI that caused me to rethink my stance on abortion. Where I was once torn between two less than ideal scenarios, I became convinced that robbing a person of his or her potential future by force was unequivocally morally wrong. Furthermore, I determined that the loss of future experiences is the main reason murder itself is morally wrong and that it has nothing to do with the cognitive abilities or previous experiences of the victim. Truly, the murderer only takes away his victim's potential future. And this is why the act is so detestable. Aborting a pregnancy is exactly the same as murder under this perspective. Remember that I am not endorsing MWI as a correct interpretation. In fact, I find it to be pure fantasy and baseless speculation. But MWI institutes many concepts that are known to be fact and it is these which I have used to explain my stance on abortion and murder in the previous paragraph. MWI is one of the most basic things you will ever learn about in physics, especially if you never receive any formal education, so very little knowledge of physics is required for this. Look it up if you are lost. I suspect most Liberals here are familiar with it, since they like to pretend they know science.
