I had the pain, and pleasure, of taking and then (assistant) teaching thermodynamics at MIT.

One of the tidbits that always stuck with me was that astronomers have estimated that observable universe’s total entropy:

When you compare that value to the maximum possible entropy, i.e. the heat death of the universe, and then to the ridiculously low entropy state of the beginning of the universe, we are currently halfway along in that ‘timeline’.

It always brought to mind a grandfather clock; the clock stops when the weight hits the floor, and we are halfway there…
