Well, it could be worse. It could be a device that causes the nuclear force that keeps atoms apart to 'disappear' and causes the atoms to merge into one giant sphere of energy and heat that presumably reaches 5 billion degrees C and can damage solar systems lightyears away because it imitates the creation of the universe.
Only on a much, much smaller scale.
There was a website I read where it pretty much said that 'if there is advanced alien life out there, then it's likely that their technology has reached the point where trying to figure out the fundamental principles behind them would be considered lethal', and used the example of a victorian engineer/scientist trying to figure out how a working, active nuclear powerplant works by taking it apart, only for him to accidently cause a meltdown when he removes the cooling rods.
....I sometimes wonder....exactly how are people supposed to work out the difference between 'alien moblie phone' and 'alien remote detonator' when even now we use moblie phones to trigger bombs?
Oh! New idea for a weapon that Revy can research for SCIENCE!!!
Hypernova Bomb: A device that breaks down one of the most important electromagnetic forces in the universe, causing all matter within it's radius to collapse in on itself, triggering a Hypernova (which is a large scale supernova event).
For the time when everything in a ten lightyear radius must die, burn them away in a cloud of superheated gas, rated at 5 billion degrees C at it's center.
Accept no subsitutes.
