Having we gone faster than light?

Or is it just an illusion?

The researchers observed that single photons that completely penetrated the stack passed through in about 12.84 femtoseconds. If the team added an additional single layer of low refractive index material to the stack at the end the photon took an additional 3.52 femtoseconds to pass through the stack.

However, if the team added a single high refractive index layer to the end of the stack the single photons were able to pass through the entire stack in 5.34 femtoseconds. With the photon passing through the stack in 5.34 femtoseconds the photon appears to travel at faster than light speeds.

  In my opinion, no, the word "appears" is a big clue.  Plus, it required going through a refractive layer to achieve such speed. The interference between the waves altered the tests too.

Most importantly, the low amount of photos being able to make such speeds made it statistically irrelevant. More studies will be needed.

Updates for 1/19

Hope everyone had a great new year's.  As for the experiments, I will not be doing the analog computer as I have moved to Platteville to attend for school and did not bring the DMM.  The memory module might be done later as well as any op-amp circuits since I will need to purchase the necessary short circuits.

One project I will run will be more of a case study of the importance of education and the BSME from my time at Jorgensen Conveyors...this should be far more simple as it will only require simulations be run in Inventor
