  What would be the consequences in physics if an exception to conservation of energy were found?

I understand that the conservation laws are "foundational" in some sense, but I have not ever heard what would be implied by the discovery of an exception. I am a layman, so please explain in simple terms.

Thanks.

low level (popular) physics. Users with 500+ reputation may vote here to close.

We are 'allmost' facing this situation if we believe recent articles ( ie : reversal time and misc violations  IBM annouce. ). Be aware, it is just buzzy lexical claims about deviations at quantum scales ...

There are too much articles today to remark something. People instead of reading with an open scientific mind, look for articles compatible with their own beliefs and publications. Communicate or perish. ( buzzish or perish )

The study of the information diffusion is very interesting. It enriches the intuition about interactions and scales and shows links with plasma physics.

just chatting, ok ? :)

It is simple: if the energy of something is not conserved, then it changes. Take a body in an external time-dependent force, and you will see the body energy is not conserved. The body moves with accelerations here and there, etc. Another example from thermodynamycs: you heat or cool some system, whose energy is thus not conserved. It symply means the system is not "closed", but "open" to external influences.
