  A reply on Talk: Ramesh Raskar: Imaging at a trillion frames per second

  Sep 19 2012: To Kirk: Photons do not interact with one another. Furthermore the closing speed of two photon packets is precisely 2c but -- key point -- there is no way of transmitting information at a speed greater than c.
  To David: Einstein's formalism reconciles different versions of what happens to be mutually consistent (not inconsistent).

• A reply on Conversation: Have all "modern scientists" forgot that all these bogus "parallel universe" theories are still just unproven theories?

  Jan 16 2012: The concept of parallel universes is speculative. Your expression "the only possible way" is in fact not correct; that is not a necessary construct to understand quantum mechanics. Hence you are departing into an area of inquiry -- which is great -- but you are departing from a fallacy so you may want to revisit your point of origin.
  
  To the point of difficulty over quantum mechanics: The rules are different on those scales than on the scale of our ordinary experience. That's all we get. In particular we don't get the right to insist on different rules. To understand quantum mechanics you simply learn the rules and then go explore with them. But it is more productive to stick with explorative ideas that are testable.

  A comment on Conversation: Have all "modern scientists" forgot that all these bogus "parallel universe" theories are still just unproven theories?

  Jan 16 2012: Of course the computer you used to write your comment was designed and built using these unproven and preposterous theories but please note that they have nothing to do in a foundational sense with speculation over parallel universes. If you are interested in exploring this further I recommend the book _QED_.
