Altering a Structure Without Changing Its Chemicasl Composition

[Pranav Nair]

My question is that can we use properties of quantum mechanics and thermodynamics to alter size of a non biological object such that properties like its density,optical activity, conductance etc remains same...
For instance we know that cooling down a substance considerably reduces its size and vice versa but if we could somehow do this process at subatomic level using quantum mechanics it could be possible to decrease or increase the size of an object as whole...

No, quantum mechanics itself doesn't allow us to do such a thing.

No, quantum mechanics itself doesn't allow us to do such a thing.

That means we cannot alter the size of subatomic particles further in any method as it would be instantly converted to energy,...am i going right? however thank you for your answer...

No. It means we cannot alter the size of subatomic particles because that is inherently impossible. It has nothing to do with anything being converted to energy.

Since this is well beyond mainstream science I'm afraid I'm going to have to lock this thread.
