A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...
Thermodynamic spontaneity—whether a reaction can go—can be measured by changes in either of two parameters: entropy or free energy.
If you start with a very specific state, for example a box full of balls that are sorted exactly by colour, then if you shake the box a little, a higher entropy mixed state will develop over time.
