E is for Entropy
Entropy will get us all in the end. In general terms, the word refers to a decline from structure into uniformity. The process by which energy within a system evens out and its order diminishes. In cosmological terms, this means the tendency for creation to become formless and homogeneous: the so-called "heat death" of the universe.
Still, it won't happen for a while yet.
The word was actually only coined in the nineteenth century, formed from the Greek entropia, meaning a turning toward.
