   I wanted to somehow ISRU the antimatter at Alpha Centuari by solar collectors,   
   so the antimatter lasers probably aren't gonna work because of the more   
   complex manufacturing required.    
      
   Also, can someone tell me if this is correct? I am trying to calculate   
   antimatter powered nuclear pulse and trying to convert joules to newtons.   
   Probably better to search it on Wikipedia   
      
   Because e = mc^2(yes, I know its not 100% efficient), mass = e/c^2. I think I   
   used 1 kiloton of tnt for e(4200000000000 joules). Substituting e/c^2 for m on   
   f=ma, we have f = (e/c^2)a, putting in 9.8m/s^2 for a because for some reason,   
   physicists use    
   earth's gravitic acceleration whenever they see an acceleration variable they   
   don't know what to do with. That's why Isp is measured in seconds. So, I have   
   0.00046 newtons.
