Why black holes put the squeeze on memory

By Justin Mullins

SO MUCH for Moore’s Law. In 1965, Gordon Moore, one of the founders of chip
maker Intel, predicted that the number of transistors that can be packed into
memory chips would keep on doubling every 18 months. While his law shows no sign
of being broken any time soon, a scientist has harnessed black hole physics to
show that computer memories cannot go on storing more and more information
forever—and that the ultimate storage limit is much closer than engineers
thought.

Jacob Bekenstein, a physicist at the Hebrew University of Jerusalem, says
that black holes are the perfect information-storage…
