It is often thought that teleporting matter, that is moving it some distance in zero amount of time, is impossible because of the velocity this would imply. What velocity would an object have if it went from one location to another in zero time? What would it's acceleration be?

When can a theory be modified if a new type of technology allows for new observations that raise new questions? a-immediately, while the questions about the theory are being asked b-after new hypotheses related to the theory are tested in experiments c-only after the new observations disprove all parts of the theory d-while scientists begin to think about how the theory could improve
