Have I sufficiently fried everyone's brains?

I AM ABOUT TO RUIN YOUR DAY:; HUMANS DON'T KNOW IF THE LAWS OF EXISTENCE ARE TRULY FUNDAMENTAL BECAUSE WE DON'T KNOW HOW THEY CAME TO BE LAWS IN THE FIRST PLACE. THEREFORE, THERE IS NOTHING, TO OUR KNOWLEDGE, STOPPING GRAVITY FROM CEASING TO EXIST OR ENERGY FROM BEING CREATED/DESTROYED; I DISCUSSED THIS AT LENGTH WITH A FRIEND ON A SCHOOL TRIP WHEN WE HAD NOTHING BETTER TO DO ON THE BUS
