If you've been watching the news lately you've probably already heard that researchers at the European Nuclear Research Centre (CERN) claimed to have successfully trapped dozens of hydrogen 'antimatter' atoms.
Many Star Trek fans would be the first to point out that the engine of the Starship Enterprise is powered by antimatter... It has also been previously stated that a Mars trip could take only days or even hours with only a single kilogram of antimatter, oppose to the 6 month trip one-way with traditional propulsion. The only problem is, you guessed it, MONEY. According to a NASA spokesman, it would take $100 billion dollars to create one milligram of antimatter.
