Probing Nuclear Forces at Extreme Conditions*

We discuss the possibility of investigation of the dynamics of the nuclear core at high energy and luminosity

experiments at Jefferson Lab. Main emphasize is given to the exploration of deep-inelastic

scattering from nuclei at x>1 and  probing non-nucleonic component in the deuteron wave function at

very large internal momenta.  In addition to the dynamics of the nuclear core we discuss also the

possibility of probing irreducible three-nucleon forces at high momenta and their relevance to

the existence of supermassive neutron stars.
