For mankind's very first time travel experiment, the identical twins Eric (a paleontologist) and Sean (a physicist) are sent on a sort of oscillating path through time, spending short periods in eras that are each exponentially farther into the future or past than the last; thus, when Eric is at a point 5 x 107 minutes into the future, Sean is at a point 5 x 107 minutes into the past; next, Sean will be 5 x 108 minutes into the past and Eric 5 x 108 minutes into the future; and so on. Why this bananas need for temporal symmetry? It's never properly explained, but there's a stab at it: Sean had brought home a pile of theoretical papers about it. Explaining how the phase-linkage coupling of a minute black hole, identical to those that are found all over interstellar space, and its mathematical opposite, a "white hole," created an incredibly powerful force that ripped right through the fabric of space-time -- and how that force could be contained and controlled, like a bomb in a basket, so that it could be used as a transit tube for making two-way movements in time. (p136) Children, do not use phrases like "phase-linkage coupling of a minute black hole" when the teacher's around. It will only cause misunderstanding and get you into trouble. But there are other dumbnesses in what it pains me to say is a pretty dumb book. The reason identical twins have been chosen for the experiment is that the two "packages" involved must be of exactly the same mass, right down to the milligram, to maintain the symmetry; otherwise everything will go bang. The very obvious fact seems to have occurred to Silverberg, after setting this up, that it's just as difficult to get the weights of adult identical twins exactly the same as it would be for any other two adults, and there's a certain amount of panicky fudging over the issue. It's lucky one of them didn't have to take a pee during their temporal adventure -- very lucky indeed, as arch-boffin experimenter Dr Ludwig explains in that typically dispassionate way scientists have: He looked ready to explode. "The past is fluid! The future is yet unborn! Anything can be changed! Anything! Who knows what will befall the entire history of the world, if anything happens to you? Who knows?" (p159) So don't so much as sneeze, d'you hear, or you'll change your body mass and screw up the symmetry and everything will go kerfluie and then you'll be sorry. Even a fart could be risky. Another thing that irritated me was that, as the twins go on bigger and bigger hops through time, their arrival points move laterally across the face of the planet, yet they always emerge standing on solid ground -- even if that solid ground is at the bottom of a mesa or in a subterranean maze of tunnels. What stops them from emerging into a new epoch in midair? Or in the middle of the ocean? It's obviously a logical dilemma faced by many other time travel novels, and most of the time we don't think about it; but here, because of the unexplained (and in plot terms surely unnecessary) geographical slippage in the twins' arrival sites, it becomes particularly glaring. And Eric meets aliens. They are a particularly daring imaginative creation: They were cone-shaped beings eight or nine feet high, with brilliant orange eyes the size of platters and rubbery blue bodies. Clusters of scarlet tentacles dangled like nests of snakes from their shoulders. They walked in an odd gliding, lurching way on suction pads that make a peculiar slurping sound as they clamped down and pulled free again. (pp195-6) It's difficult not to find oneself musing that, if the employment situation becomes grim in the aliens biz, this lot could always get jobs with The Muppet Show. Silverberg has always been one of science fiction's more intelligent practitioners. It's difficult to conceive why he should be writing such stuff. Maybe it was a flat-fee commission and his heart wasn't in it. Or something. sin reseñas | añadir una reseña

OK, it's not even much of an idea (the logical holes are obvious, as with most time-travel fiction.)
But there's no story. They do the experiment, it happens.
That's it. No plot, no tension, not even much character generation. No disasters occur, no revelations about the past or future are gleaned. So why read this book? ( )
