People may not be aware of the Big Freeze. It┬аis the theoretical end of┬аeverything. It is the stage at which the universe has stretched to having no leverage of┬аthermodynamic energy. In other words, it is the threshold at which the entire universe will cease to┬аmaintain┬аmotion. The entire universe will become┬аabsolute zero. It is the┬аcoldest┬аtemperature, where everything is at a standstill. In short, the Big Freeze is a period of infinite, everlasting, and┬аabsolutely quiet darkness. It will not repeat┬аfor another 100 trillion years or more. It has to be kept in mind┬аthat an actual perpetual motion machine would be capable of running for at least that long.
Many plans for perpetual motion machines may be seen online┬аthat claim to be functional. Looking at those designs, it is not illogical┬аto believe that some of them could (if properly designed) continue running. If someone wants to succeed, the impact would be massive. There is an infinite supply of energy. However, it┬аwould be more than that by way of┬аunrestricted energy. Perpetual motion devices governed by the Law of Perpetual Motion┬аare, unfortunately, unattainable related to the inherent physics of the universe.
