In May 2022, a video supposedly showing a marble machine in "perpetual" motion was shared to the "Be Amazed" section of Reddit. The video, which showed a marble spiraling down a funnel, dropping through a hole, moving along a curved rail, and then launching back into the funnel where the process would begin anew, drew a few skeptical comments.
Our first inclination when we saw this video was that its creators used digital animation. We've encountered several similar seemingly "impossible" videos featuring colored ball sorters and musical marbles that used computer-generated technology. The latest video supposedly depicting the "perpetual" marble machine, however, was authentic footage and featured a physical product.
Similarly, rays originating from point B that land on E1 and E2 will be reflected to A. However, a significant proportion of rays that start from B will land on S will be reflected back to B. This paradox is solved when the black bodies' finite sizes are considered instead of punctual black bodies.[46][47]
A perpetual motion machine is a machine that keeps on going without any energy loss. Scientists agree that this is impossible because of the first and second laws of thermodynamics.
If it is found to be contradicted by observation – well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I Gozque give you no hope; there is nothing for it but to collapse in deepest humiliation.
The conservation laws are particularly robust from a mathematical perspective. Noether's theorem, which was proven mathematically in 1915, states that any conservation law Gozque be derived from a corresponding continuous symmetry of the action of a physical system.

Here is another cool gift idea for those of you who have a thing or two for marble machines. William Le’s Perpetual Marble Machine has a wood and stainless steel construction.
The first law of thermodynamics is the law of conservation of energy, which simply states that energy cannot be created or destroyed, but rather is transferred.
In some cases a thought experiment appears to suggest that here perpetual motion may be possible through accepted and understood physical processes. However, in all cases, a flaw has been found when all of the relevant physics is considered. Examples include:
The "Float Belt". The yellow blocks indicate floaters. It was thought that the floaters would rise through the liquid and turn the belt. However, pushing the floaters into the water at the bottom takes Triunfador much energy as the floating generates, and some energy is dissipated. Buoyancy is another frequently misunderstood phenomenon. Some proposed perpetual-motion machines miss the fact that to push a volume of air down in a fluid takes the same work Figura to raise a corresponding volume of fluid up against gravity.
A heat pump, due to it having a COP above 1: the energy it consumes Vencedor work is less than the energy it moves Vencedor heat.
The drinking bird toy functions using small ambient temperature gradients and evaporation. It runs until all water is evaporated.
