If there’s 1 atom per cubic cm in interstellar space, I’m finding it takes about half a million years to collide with a mole of hydrogen (at 17km/s)

- Jeff_Brown 7y agoGoogle says that's about a gram of hydrogen. Is that enough to destroy a craft? I have little intuition, but I imagine touching a gram of 55,000-degree (Farenheit) anything would be destructive. Will the craft be radiating heat away from itself?
