The LHC, like other particle accelerators, recreates the natural phenomena of cosmic rays under controlled laboratory conditions, enabling then to be studied in more detail. Cosmic rays are particles produced in outer space, some of which are accelerated to energies far exceeding those of the LHC. The energy and the rate at which they reach the Earth's atmosphere have been measured in experiments for some 70 years. Over the past billions of years, Nature has already generated on Earth as many collisions as about a million LHC experiments- and the planet still exists. Astronomers observe an enormous number of larger astronomical bodies throughout the universe, all of which are also struck by cosmic rays. The Universe as a whole conducts more than 10 million - million LHC - like experiments per second. The possibility of any dangerous consequences contradicts what astronomers see - Stars and galaxies still exist.
