Hungry Pet. For starters, the scientists recently told the New York Academy of Sciences, one of the black holes would have to be located. For example, a small, unaccountable gravitational tug on a spacecraft might be a good indication that one was near...
Once the black hole was positioned in a permanent orbit around the earth, its gravity could be tapped. From a distance of 100 yds. or so-far enough away to avoid being drawn into the black hole -an automatic firing mechanism on a spacecraft orbiting near by would aim tiny pellets of matter at it. Almost any material would do. As each pellet plunged toward the black hole, it would be squeezed and heated by the gravitational field to tremendously high temperatures, perhaps 100 million degrees...
...reaction that fires the sun or an H-bomb. Some of the material would be consumed by the black hole, but most of it would be explosively blown away as extremely hot electrified gases. By letting these gases pass through a magnetic field created by a generator aboard the spacecraft, a powerful electric current could be induced in wires rigged outside the craft...
There was also triumph for the space agency's latest unmanned spacecraft. Barely two years after a similar robot began the first detailed mapping of Mars, and only weeks after another peeked at giant Jupiter, a 1,108-lb. ship named Mariner 10 last week cruised by the earth's nearest neighbor, Venus. In the first clear pictures of the planet, Mariner's cameras showed great circular cloud formations, raising the possibility that Venus may have an atmospheric circulation something like the earth...
...reaching that understanding, for the brain is an organ of enormous complexity. While a sophisticated electronic computer can store and recall some 100 billion "bits" of information, for example, the capacity of the brain seems infinite. The computer can make out a payroll, compute the trajectory of a spacecraft or figure the odds against drawing a straight flush far faster than any human. But the computer is, after all, a machine, capable of doing only what its human builders tell...
