SCIENTISTS claim they have broken the ultimate speed barrier:
the speed of light. In research carried out in the United States,
particle physicists have shown that light pulses can be accelerated
to up to 300 times their normal velocity of 186,000 miles per second.
The implications, like the speed, are mind-boggling. On one
interpretation it means that light will arrive at its destination almost
before it has started its journey. In effect, it is leaping forward in

I have a question regarding the speed of light.Im not an expert just someone who is interested in physics. If as Einstein theorised, nothing can travel faster than the speed of light then how is the following possible.Is this just bogus information/site.
Another query i have is what speed does electricity travel at, doesnt it travel also at the speed of light.
Where does the speed of gravity fit into Einsteins special relativity.

Electricity "can" go as fast as light, but in the applications we use it in actualy moves rather slow.
This because your dealing with free electrons moving trough solid conductors that are alread filled with electrons.

You are all smarter than me about those speed of light things. But I'm wondering what if their discovery was due to the measuring equipment they were using. That sensitive electron microscope mentioned in the article, let's say the particle travel so fast from one point to the other before that microscope has time to flip to the next clock cycle, so the hardware get confused and report the light as arriving before it left? Just my unenlightened 2 cents.
