The second force that'll hit the Roadster is radiation. "Anything with plastic or rubber will degrade because of cosmic ray radiation, energy from cosmic rays floating around in space that tends to disrupt chemical bonds," Narita says. Radiation is really tough on carbon bonds, like those present in plastics and rubber. "The metal structure itself should be fine and last for hundreds of thousands of years." Turner adds that the plastic and rubber bits of the car, like the wheels and the seats, will get worn down and mottled in a few years, and eventually be shredded by that radiation.
