No.

The first law of thermodynamics implies that the energy of the universe is finite. As a consequence the specific heat of a substance - defined as H/m where H is enthalpy and m is mass. Either H would have to be infinite or m would have to be zero. If m is zero, then the ratio is meaningless because you don't have anything to assign the enthalpy to. H = U+PV. For H to be infinite either U (internal energy) has to be infinite - but we've already established that the 1st law says total energy of the universe is finite, so that's not the case - or PV is infinite. You aren't going to get P (pressure) to be infinite so V would have to be infinite, i.e. zero density - again, if density is zero, there is effectively nothing there. Since we've eliminated all possibilities for any of the necessary terms to be infinite, specific heat cannot be infinite.
