It’s official: neutrinos can’t beat speed of light

Physicists at the CERN laboratory have put the final nail in the coffin for the idea that neutrinos can travel faster than the speed of light. They also confirmed that the groundbreaking results from 2011 can be blamed on faulty equipment.

Back in September 2011, a team of particle physicists detected neutrinos moving faster than the speed of light as they travelled from CERN to the Gran Sasso lab. They smashed the universal speed limit by 60 nanoseconds — a result that was constant, even after 15,000 repetitions of the process.

The results seem to run counter to century’s worth of physics and would overturn Einsten’s special theory of relativity if true. As such, CERN called for more experiments to double-check the findings.

When faced with the need for more of something, one possible solution is expansion. This could take many forms but one simple way is extending it to be greater in size, such as adding the dining room table leaves to fit more people around the Thanksgiving table. Samtec’s...

Given that the industry is beginning to reach the limits of what can physically and economically be achieved through further shrinkage of process geometries, reducing feature size and increasing transistor counts is no longer achieving the same result it once did. Instead the...
