The entropy of the universe increases because energy never flows uphill spontaneouslbecause
Energy always flows downhill, and this causes an increase of entropy.
Entropy is the spreading out of energy, and energy tends to spread out as much as possible.
It flows spontaneously from a hot (i.e. highly energetic) region to a cold (less energetic) region.
As a result, energy becomes evenly distributed across the two regions, and the temperature of the two regions becomes equal.
The same thing happens on a much larger scale. The Sun and every other star are radiating energy into the universe.
However, they can’t do it forever. Eventually the stars will cool down, and heat will have spread out so much that there won’t be warmer objects and cooler objects.
Everything will be the same very cold temperature.
Once everything is at the same temperature, there’s no reason for anything to change what it’s doing.
The universe will have run down completely, and the entropy of the universe will be as high as it is ever going to get.
