The ultimate in alternative package holidays is possible. In ‘Two Ways to Build ATlme Machine’, John Gribbln, astrophysiclst and science writer reveals the perlect solution lor those who are sick ol the present- travel in the iourth dimension.

This is the subject oi Gribbin’s latest book, ‘The Cartoon History oi Time’, co-written and Illustrated by Kate Charlesworth, in which the Amazing Boliin Junior Chicken, and Alexis, the Quantum Cat explore iiie, the universe and (almost) everything, demonstrating that the laws oi physics allow us to travel through time both ways.

‘One way to travel to the luture,’ says Gribbln, ‘is to go on a long journey at a very high speed. When you return, many more years will have passed on

the most blzzare objects in the universe - a black hole. Black holes are thought to be ionned irom stars that become so big that their own weight overwhelms the normal lorces that atoms experience, so that they collapse and shrink to a point oi incredible density and a tiny volume. Such an object has a gravitational ileid that is so strong that it behaves like ‘cosmic quicksand’, sucking in everything that ventures too close, including light (which is why it is black). it also appears that close to a black hole, time slows down.

Black holes may also oiter the possibility oi time travel, both iorwards and back in time. Gribbin describes how regions ol past and luture can be created using two black holes. it has even been speculated that whenever you time travel you arrive in an alternate reality. There may be no unique history oi time.

Gribbin will also discuss the so-called ‘granny paradox’, the trick oi swapping time lor space, alternative realities and more. And he swears ‘on Einstein’s socks’ that every word is true. (Hazel Muir)

John Gribbon is at the Royal Scottish Museum 4 Apr, 4pm. Tickets £1 (50p) are available irom the Science Festival box oilice.
