Faster than light neutrinos? More like faulty wiring

You can shelf your designs for a warp drive engine (for now) and put the DeLorean back in the garage; it turns out neutrinos may not have broken any cosmic speed limits after all.

Quantum speed limits are not actually quantum

Quantum mechanics has fundamental speed limits—upper bounds on the rate at which quantum systems can evolve. However, two groups working independently have published papers showing for the first time that quantum speed ...

Quantum effects lead to more powerful battery charging

(Phys.org)—Physicists have theoretically shown that, when multiple nanoscale batteries are coupled together, they can be charged faster than if each battery was charged individually. The improvement arises from collective ...

Energy researchers break the catalytic speed limit

A team of researchers from the University of Minnesota and University of Massachusetts Amherst has discovered new technology that can speed up chemical reactions 10,000 times faster than the current reaction rate limit. These ...

Traffic jams follow explosive pattern, says researcher (w/Video)

(PhysOrg.com) -- Picture this next time you're stuck in traffic: Thousands of wildebeests loping across the Serengeti Plain when suddenly a few spooked animals turn the orderly migration into a sea of locked horns, U-turns, ...

Five things to consider before speed limiters are added to cars

The recent announcement that EU rules for fitting speed limiters to new cars from 2022 will be adopted by the UK was welcomed by many, including the European Transport Safety Council, as a move that will save lives. However, ...

Speed limit

A road speed limit is the maximum speed allowed by law for road vehicles. Speed limits are commonly set and enforced by the legislative bodies of nations or provincial governments, such as countries within the world.

The first maximum speed limit was the 10 miles per hour (16 km/h) limit introduced in the United Kingdom in 1861.

The Isle of Man is the only place in the world that does not have a general speed limit. In Germany, over 50% of the autobahn system remains free from speed limits.

Currently, the highest posted speed limit in the world is 140 kilometres per hour (87 mph) on Polish motorways , although a variable speed limit up to 160 kilometres per hour (99 mph) was permitted experimentally on a stretch of Austrian motorway in June 2006.
