Second law of thermodynamics in relation to "Universe"?

My understanding is that the empty space in our Universe is energy since entropy dictates presence of matter everywhere without empty regions but since ours has so much vacuum it can only be looked at as a form of "order" where matter is accumulated on one side and empty space on another(gas in a container that does not fill the whole container), therefore potential energy since the total amount of entropy in the Universe increases with any real process but since there is so much space(as a matter of fact the rate of expansion of the universe is faster than the rate of increase in entropy) and it is unfilled it can only be regarded as potential energy or counter-entropy energy , where finally, there is only matter and energy in the Universe and nothing else(antimatter is form of matter). Thus the 2nd law of thermodynamics is actually false if you consider the "Universe" since the rate of expansion of our Universe is greater than the rate of entropy increase since we see more vacuum by seeing galaxies and planetoids move farther apart from each other without increasing in size in return. Therefore with each real process the total entropy of the Universe decreases and approaches zero, thus second law of thermodynamics is wrong and should be rephrased, an experiment to prove this would be an empty container in space behind Earth in relation to the Sun, since the sun will increase the temperature of the container, the experiment would consist of several empty containers floating in vacuum of space and fairly distant from each other with a few molecules causing a spontaneous increase in temperature within the container after the lowest temperature plateau is reached due to cooling in space, however time dilation should be taken into account. The reason is because the expansion of vacuum will push matter outward since vacuum is energy and several free floating gas particles will not be restricted by intermolecular forces as much as those that make up the container. Afterall, its not the entropy that increases with each real irreversible process, its the total (energy + matter) as time moves forward
