It's possible, but it would require a dynamic I am not familiar with.

In order to answer this, I went and looked up the law, just to make certain that I remembered the integral correctly. The answer is that given only the formula of the law, that cannot be answered. In a closed system, the derivative dS/dt, also sometimes notated as a S with a dot over it, is greater or equal to zero, which means it could not be reversed. It must either increase with time or increase to a maximum. However, the law itself does not provide enough information about the Universe itself to answer that question, given only the law.
I would note that a scientific law is not a theory, but a rule of thumb that works in most circumstances. One complaint about the second law is its lack of specificity. It is important to remember that heat and temperature refer to average events, which implies a sufficient quantity of particles to act on one another. The law does not describe the scales at which it will and will not operate. It also does not consider the impact of other forces of nature. Only temperature and heat exist within the law itself. As such, there is a presumption of equilibrium in the other forces, or they are well defined in the closed system.
It is important to remember that heat is the energy transfer from one body to another due to a difference in temperature, while temperature itself may be thought of as the average energy in a system, at least those are decent approximate definitions. Entropy is defined as their ratio. It is impossible on a macro scale for the law to be wrong, if the system has well defined temperatures.
It also does not deal with stochastic variation where the disturbance term is in expectations equal to zero. You could have a local reversal that will in turn eventually reverse itself so that in expectation the loss of entropy averages out over time. This is a deterministic integral.

Stephen Hawking thought so. He came up with some ridiculous theory that time reversed when the Universe began contracting. Hawking was proved to be incorrect mathematically.
Theoretically the answer is yes, reverse of time and entropy is possible. In the currently accepted model of the Universe entropy cannot reverse under any foreseeable conditions.
PS: Very good, yes, in an open system entropy can be reversed. The universe exists and is in motion and therefore must be either intermittently or constantly open.

There are some theories. One is a heat temperature dying, wherein entropy finally wins out over each and every ingredient. there is likewise an amazing Crunch, wherein the universe collapses on itself returned. additionally, the massive Rip thought, the optimal modern of them, is predicated on the on the prompt have been given right here upon dark skill. it somewhat is my properly-loved and is anticipated to wreck the universe in 20 billion years mutually as no longer even atoms are able to withstanding the enhance of section, which in accordance to this thought is accelerating exponentially.

No.
If you consider a small system. I can very easily clean my room thus decreasing the entropy of my room. But in cleaning my room I expend energy (which creates more gaseous molecules) and interfere with all the dust, bunnies, and air in my room. So overall no.

How the heck would I know? It's interesting though that this "law" is based on linear, mechanical processes. Its application to random processes is not very clear, especially in biological processes. Seems to me that "life" can transcend thermodynamics, though it cannot permanently evade it.
Peace to you.

It could if we had an open universe that received energy from some external source. It only applies to closed systems.

Only locally.
It may also be decreased in a collapsing universe, but we don't have one available to test.

The thought is that if the Universe collapses back in on itself it would do just that.
It is also possible if there is an input of energy from outside.

Only in an open system such as life.
