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 - https://horizon-magazine.eu/article/antimatter-and-gamma-rays-help-steer-cancer-killing-machines_en.html 

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 - http://www.scienceforums.net/topic/51224-anti-space/

 
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?
