Aristotle explicitly taught that perpetual motion was only possible in the intersidereal field, so the idea is not new!
The first search for a perpetual motion machine (historically known) was made by the Hindu scholar Bhascara.
The idea was then taken up by the Arabs around 1200 before spreading to Europe ... until today!

Thermodynamics I understood but can you say that all that we tell you at 20 pm on tf1 is true or at least has not been manipulated?
Given the immense potential of unlimited energy, do you think that the government would have left such a golden egg hen aside?
In addition, no scientific research is unprecedented for a long time, it seems oddly that when we discover something, another researcher often on the other side of the world ends up discovering what is often well kept by the opposing team (example Bomb A and H).
Thermodynamics is much more than a simple relationship between a hot and cold source, it is also the engine of our universe and the guarantor of its proper functioning!
Can not we say one day that Einstein is deceived or at least did not understand everything?
It is clear that Einstein only explained a small part of reality, indeed, the theory of relativity is not compatible with the indeterminism of quantum physics, this does not validate pseudo- theories scientist.
We will soon (within 100-200 years?) Be able to explain almost everything in the universe, but paradoxically unable to explain the reason for this existence.
Etienne Klein said about it: "the theory of everything is not the theory of everything".
Does dark matter exist?
Opinions are divided, an increasing number of scientists believe that dark matter does not exist, and that it would be an error of interpretation of the current theoretical framework ... wait and see!
Does one really live in a universe in 3 dimensions or 4 over time?
Our current knowledge shows 4 dimensions (1 of time and 3 of space).
String theory nevertheless postulates the existence of dimensions wound at 10, see 26 dimensions!
Some scientists go further and believe that neither space nor time exists as such, but as a by-product of reality (idea very long defended in Hindu texts!)
In general it is the opposite, it is from practice that born the theory, nevertheless when we arrive at quantum dimensions it is necessary to have recourse to theories because it is no longer possible to be able to observe the nature of reality, this is also the case with subjects like black holes and the Big Bang.Why put the theory before practice.
