Man will kill himself in space when his space ship has unlimited energy.
Space being so big he will want to go faster and faster. At 94% of "C"
he has killed himself. Going through space can be very boring,and he
might forget to look at his gravity meter. His space ship is closing in
on a microscopic blackhole. It is the size of a proton,but has the
weight(inertia) of a large mountain. He knows all this,and still let it
happen. It is Murphy"s law. Bert
