Accelerating a macroscopic object like the ISS to the speeds of protons at the LHC would require an immense amount of energy, approximately 6 x 10^21 J/kg. This translates to about 10 times the annual global energy consumption for each kilogram of mass. The ISS, weighing over 400,000 kg, would thus require energy on an unprecedented scale. The challenge lies in the fact that elementary particles can be easily accelerated due to their significant charge-to-weight ratio, a principle that does not apply to larger objects like the ISS. Achieving such speeds would be extraordinarily difficult, highlighting the limitations of current technology in accelerating large masses to relativistic speeds.
