     What is the importance of antimatter?
     As is known, I don't understand physics.
     The front page of wikipedia links to new results in antimatter
     related to antihydrogen.

     What is the importance of antimatter not counting nukes?

   Amongst other things, there's a line of research that suggests that
   it's also helpful in treating cancer

   In theory, it could also be used as a fuel in space travel - whether
   that's ever going to be doable is something else - the idea being that
   an annihilation is pure energy, so if you can direct it, you may be
   able to travel quite efficiently.
   I don't think there'd be a use in Nukes (as we know them).
   Theoretically you could build a similar weapon, but there'd be a huge
   cost in acquiring and storing the AM, especially once placed into a
   weapon. Nukes tend to fail-safe, whereas a failure in an AM weapon
   would almost certainly result in detonation.

     Why antimatter is accepted by the standard model in physics, but
     anti-time and anti-space appear to be considered cranky topic?

   I guess it depends on what you mean by anti-time and anti-space. But in
   either case, there's a thread of people doing a far better job than I
   could of explaining here

     Could it be currently we don't have measuring devices and enough
     precision to detect anti-time and anti-space and the imaginary (in
     the
     complex sense) stuff from the square root of negative real in the
     Lorentz transformations, closely related to relativity?
