Now assume you are duplicated in universe X and universe Y, in both of which which you have an identical mental state. However, in universe X you have a red car, and in universe Y you have a blue car. When this memory surfaces, you identify which universe you are in. Before the memory of the color of your car surfaced, your mental state was identical and it could be said that your consciousness supervened on both of them. > But then when the yellowness or redness of my toothbrush enters my > consciousness my mind splits into different universes (the many-minds > interpretation of QM?).

Nothing happens to you between now and the next minute (your consciousness continues through that time) 2. 30 seconds from now, you will be blown to pieces, but then nanobots will repair you perfectly such that you don't even notice (your consciousness continues) 3. You will be blown to pieces, but then nanobots repair you perfectly (only this time using different matter) you don't notice and your consciousness continues. 4. You will be blow to pieces but then recreated at another location in the exact configuration that you were before you were blown up (From your perspective your surroundings suddenly and inexplicably changed) 5. You are blown up and then two copies of you are created, one in your present location and another in a second location. You now cannot be sure which one you will be. For some short period of time you can be said to be both of them (until different sensory data is processed and the minds diverge). 6. You are not blown up, but a second duplicate of you is created elsewhere (as before, your mind can be said to inhabit both of them, until the mental state diverges) These are just the same basic examples from Bruno's UDA. Was there a particular step in the UDA that you disagreed with?
