Only if you install the Flux Capacitor in your Tardis ;) ... Even Einstein didn't call E=MC**@ a law, just a good approximation of what he could determine. And to that extent the string theorists have proven that Einstein was wright, in that his statement was wrong, at least around the 'edges', but it, likes Newton's 'laws', are good within their defined domain. Things tend to brake down at the 'edges' and when boundry conditions that need new understandings happen.
I am guessing we will find the same with Moore's Law. Do we really need transistors? Yep, flux capacitors could be the next 'big thing' so we can re-start discussing Moore's law, Global Warming, Global Cooling and all the 'important topics' of the day! Time to go back to my hobbit hole and drink some KoolAide andrew mcelroy wrote: > > > On Tue, Nov 11, 2008 at 9:04 AM, Andrew Farnsworth <[EMAIL PROTECTED] > <mailto:[EMAIL PROTECTED]>> wrote: > > Nope, it means that to continue Moore's law we will need to start > making our computer chips out of denser and denser matter.
