It’s amazing! To think - they’ve advanced as far as atomic energy, and yet - they’re unfamiliar with the galaxy's most common all-purpose weapon! 
History
A Universal Beam Blaster is a type of multi-purpose weapon that can produce different forms of energy.[1] It is capable of blasting objects into nothingness, and then using magnetic forces to reconstruct them near-perfectly.[2] It could also emit "black light" used to blind opponents,[1] and extinguish fire.[3]
Originally Captain Marvel carried his Uni-Beam as a pistol, but he later modified it into a wristband as it was easier to carry while in his human identity.[2]
