why is the tallest building on earth less than half a mile high? why don't we have mountains as tall
as those on mars?
in the last of this year's christmas lectures, dr mark miodownik investigates the world of the very
big and very tall. he reveals that, at this scale, everything is governed by a battle with one of
the strangest forces in the universe - gravity.
with help from acrobats, levitation devices, spiders, birthday cake candles and even some sticky
goo, mark discovers how gravity can make solid rock behave like a liquid and investigates whether
one day it might be possible to build a structure from earth into space, taking us beyond the reach
of gravity without the use of rocket.
