Making time travel a reality....A year later, he read a 15 cent
illustrated redaction of H G Wells's classic novel The Time Machine,
which gave him the idea to build a device that would allow him to
return to 1955 and save his father's life. So far the story is
fabulous, painful and babyish, the stuff of Hollywood - but fast-
forward 47 years to June 2002, and the same Ronald Mallett, now
professor of theoretical physics at the University of Connecticut, is
delivering a paper in Washington to around 50 of the world's most
distinguished physicists at the International Association for
Relativistic Dynamics third biennial conference, in which he explains
how a machine involving a circuit of lasers could, in theory, send a
particle backwards in time.....It has long been known that Einstein's
relativity allows for certain forms of theoretical time
travel.....Mallett is still working on his prototype, which he
believes is capable of creating a closed loop in time. "As for
travelling into the past, I believe it will ultimately happen," he
says, but the tragedy he concedes is that he will never get to see his
father again even if his machine is ready by tomorrow: for it will
only allow him back as far as the moment when it was first switched
on. The question the reader must ask is how seriously this should be
taken. There can be no doubting the author's sincerity or the strength
of his convictions. Scientific objections to his theory may be found
on the internet but are not treated at any length in the book. As a
psychological portrait of a person irreparably damaged by the death of
a parent, and of a theoretical physicist anxious that he will never be
taken seriously because he is black, working on time machines and
driven by emotion, this book makes for absorbing reading."

So absorbing reading is guaranteed. People SHOULD buy Mallett's book -
in any event, their money will go to "a person irreparably damaged by
the death of a parent". There is compassion in Einstein zombie world.
