(This is the kind of stuff I google all the time.) Welcome to the Antimatter Calculator! A calculator that shows just how far away you need to be to survive an antimatter explosion. In order to use this, simply select the system you want to use (meteoric or imperial) and press space. Then, type the mass you want to explode and press enter. Then you'll know the answer to this really weird and dumb question. If you are actually interested in the weird stuff I google and want to see more, Tell me in the comments and I might make more weird things like this. https://www.youtube.com/watch?v=e6OLj2sbYb8
