    The Earth is built to last. It is 4.5 billion years old. It has taken more devastating asteroid hits in its lifetime than you've had hot dinners, and it still orbits happily around the sun. But physics is a curious thing and it can harness devastating power -- enough even to destroy the world. Naked Science will analyze antimatter, black holes and even more amazing means of destruction -- and the havoc they could wreak on a planet. So strap in, buckle up, and enjoy the ride to doomsday.

    Millions of years ago, Venus and Earth cut similar figures. Roughly the same size and about the same distance from the sun, their respective evolutions could have followed similar paths. But today, Venus is a seething vision of Hell, its battery-acid atmosphere and incessant, hurricane-force winds masking a blistering volcanic surface. Some scientists wonder if it is a harbinger of whats in store for Earth. Thanks to the European Space Agency, Venus Express the most sophisticated satellite ever to visit the planet is orbiting Earths estranged twin, gathering the data we need to figure out why Venus went bad. Could our home planet be hurtling towards a similar fate? And could the hostile Venusian environment, now seemingly devoid of biologys most fundamental ingredient water yet harbour life?

Dubbed the Antikythera mechanism (for the location of the shipwreck from which it came), the device is considered the world's first computer, developed by the Greeks around the 1st century B.C. Scientists continue to marvel at its intricate system of gears which rival that of the most complex Swiss watch.
