Ok it's not stalking or shooting related but have a look at the ballistics of this...
It just shows how important the velocity squared part of the e = 1/2 mvsquared formula is.
The "projectile" clocks 363 megajoules, equivalent to a 400 tonFrench TGV train doing 150kph.
Check out the other equivalents too.
I remember when they were about to fire it up for the first time and one scientist was asked, "is there any possibility of opening a black hole here". He replied, "no of course not".
Another scientist said in an interview, "it's really exciting, we don't really know what will happen".
What I'd like to know is... what happens if all that energy goes wrong?.
I'm just glad the uk isn't being used as a "backstop".
