WELCOME
EVERYONE KNOWS THAT nothing can travel faster
than light. Yet this month’s big movie
Interstellar
depicts a way of doing just that. If you could fly a
spacecraft into a wormhole, suggests the film, you
could take a shortcut through space and time. On
p36, Stuart Clark examines wormholes and other
ways we could exceed the cosmic speed limit.
I’d love to visit the past to see living dinosaurs. I’ve
seen fossils in the Natural History Museum, but what
did they look like in the flesh? Strange as it may seem,
the answer may be ‘feathered’. Author John Pickrell investigates on p61.
Millions of years after dinosaurs, humans learned to use tools. And around
17,000 years ago, some of our ancestors used these tools to paint on the
walls of Lascaux caves in France. Now, modern technology is preserving
the past by creating a precise replica. Find out how it was done on p79.
Back in the Stone Age, animals had yet to be tamed – and if you own a cat,
you’ll know it still has a wild side. Dr John Bradshaw, presenter of a new
BBC TV series, finds out just how wild your feline can be on p51.
Elsewhere we look at robot swarms (p54), ask whether screens are bad
for you (p45) and journey to the heart of a human cell (p94). Enjoy the issue!
