The acceleration of the expansion of the universe places limits on future developments in technology according to two US cosmologists. Lawrence Krauss and Glenn Starkman of Case Western Reserve University have shown that the acceleration could put a fundamental limit on the total amout of information that can be stored and processed in the future (arXiv.org/abs/astro-ph/0404510). They also calculate that Moore’s Law will remain valid for no more than 600 years — although workers in the semiconductor industry are more pessimistic and think that the famous law will break down in the next decade or two.
It is well known that the amount of information that can be processed and stored in any device is ultimately limited by the laws of quantum mechanics. However, Krauss and Starkman have shown that the nature of the universe itself also places limits on computation because it is not possible to transmit or receive information beyond the so-called global event-horizon in an accelerating universe.
