Haha, no you didn't. You give a different camera view. A view that didn't have the lower part of the building in shot. Duh. That's all you needed to type. Keep denying, keep evading. I'm positive you don't actually know what refraction is or what the hell is being refracted and why! The building shows a wave in perfect sync with the penthouse collapse. It's game over folks. Demolition, (for no apparent reason!) disproven.
