Mamy wakacje, a wiec nieco wakacyjny temat zlezaly juz rok:

Einstein predicted that particles and information can't travel faster than
the speed of light - but phenomenon like radio waves? That's a different
story, said Singleton, a Los Alamos National Laboratory Fellow.
Singleton has created a gadget that abuses radio waves so severely that they
finally give in and travel faster than light.
The polarization synchrotron combines the waves with a rapidly spinning
magnetic field, and the result could explain why pulsars - which are
super-dense spinning stars that are a subclass of neutron stars - emit such
powerful signals, a phenomenon that has baffled many scientists, Singleton
said.
"Pulsars are rapidly rotating neutron stars that emit radio waves in pulses,
but what we don't know is why these pulses are so bright or why they travel
such long distances," Singleton said. "What we think is these are
transmitting the same way our machine does."
And beyond explaining what has been a bit of a mystery to the astronomical
community, Singleton's discovery could have wide-ranging technological
impacts in areas such as medicine and communications, he said.
[...]
One possible use for the resulting speedy radio waves - which are packed
into a very powerful wave the size of a pencil point - could be the creation
of a new generation of cell phones that communicate directly to satellites,
rather than transmitting through relay towers as they now do.

The Department of Energy has given them a three-year,
$3 million grant to work on the project.

Trzy lata od 2008 to 2011 - poczekamy wiec na komorki komunikujace sie
falami e-m biegnacymi szybciej od swiatla :) i wytlumaczenie jasnosci
pulsarow ... i zaprzeczenie ekspansji Wszechswiata :)
BTW, czy ktos czytal szerzej o tym eksperymencie z Los Alamos?
P.S.
Uprzedzajac pytania. Singleton ma kwalifikacje naukowe. To nie
paranaukowiec.
"Singleton holds doctoral and master's degrees in physics from Oxford
University in the United Kingdom."
