Title: Computers have speed limit as unbreakable as speed of light

A pair of physicists have shown that if processors continue to accelerate in accordance to Moore’s Law, we’ll hit the wall of faster processing in roughly 75 years.

In a recently published paper in the journal Physical Review Letters, Levitin and Toffoli present an equation for the minimum sliver of time it takes for a single computation to occur and establishes the speed limit for all possible computers.

Using their equation, Levitin and Toffoli calculated that, for every unit of energy, a perfect quantum computer spits out ten quadrillion more operations each second than today’s fastest processors, according to Inside Science.

There are objects that travel beyond the speed of light.

Processor fabrication using new technologies such as imprint lithography, graphene, and quantum computing will continue to yield faster and smaller chips. Nonetheless, those advanced techniques only stave off the absolute ceiling for speed, no matter how small the components get, according to physicists Lev Levitin and Tommaso Toffoli at Boston University in Massachusetts.

Nothing travels faster than the speed of light.

Unless you have a radical new theory of physics you'd like to reveal to us.  ::)

I am not going to worry about this as I will be in Heaven with the 100 Virgins Allah promised me:

I think I'll pass on the guys though as now its not my thing and 70 nubile young babes should keep me busy for a while and I may forget about anti virus things and taxes.

It's actually a myth- a mistranslation: he actually promised a bunch of grapes.

That's what the Infidels want you to believe.

A scientist has created a gadget that can make radio waves travel faster than light.

Yep, top speed of the original Enterprise was Warp 8 ( Which is 512 x The speed of Light)

Voyager goes up to 9.975. But it's still slower than the Borg. ;D

OK, some basic physics.

Neither the warp drive nor the hyperspace drive allow faster than light travel. They allow travel from point A to B at an apparent faster than light speed, but do so by either distorting or passing through the space time continuum.

Warp drive, as invented by Zefram Cochrane, relies on the creation of a displacement field (a warp bubble), allowing a space ship to travel through subspace at a speed which to travellers and observers alike seems to exceed the speed of light.

The speed of light is not really a speed limit at all- rather the point at which time stands absolutely still. (This of course makes travel at speeds near the speed of light awkward- as all the people you set out to see will be dead by the time you arrive, and all the people you left behind will be dead by the time you get back.) To travel faster than the speed of light would be to travel backward in time. The developers of the warp drive of course recognised this and at first called their drive the "time warp" drive, until this was remembered to be the name of a 20th dance routine. Rather than travelling faster than the speed of light, travellers in a warp drive spaceship are in fact travelling backward in time from a point in the future when they will be at point B (the place of course where they want to be), whilst retaining their incremental spatial distance from point A.

On the other hand, the hyperspace drive, as invented by USRobots, allows a spaceship to "jump" through the normal space time continuum to another point in space time.

Superman of course is merely a comic book character and not real.  ;)

I had a sneaking suspicion that you were a bit of a physicist FwF ;D

I dnt quite understand the "traveling back in time thingy" as that would be impossible?^^ ;D

Sorry but Im still a chemist, not a physicist^^ ;D(Im still in 3rd year HS who studies chem)

@+AdDicT+

Chemists work with reality Physicists work with theories that are only limited by their imagination and some are better than others.
