One of the most peculiar aspects of certain UFO encounters is the apparent fragmentation or recombination of the objects.
Both of which go against our current understanding of the rules of physics.
A variety of theories are put out by UFO believers to account for the phenomena they claim to have experienced.
There's a hypothesis that the craft itself function like enormous Lego sets.
It's also possible that, just as our own booster rockets are meant to separate and be destroyed after a launch into space.
On the other hand, it doesn't necessarily account for how witnesses have seen UFOs split apart and reassemble.
