121. Speed of light CAN be slowed

I have become aware from Einsteins equation that if we can show the speed of light to be 'slowable' then it has to affect our measure of time.

I think thats the last frontier to proving that the wotrld is not billions of years old, maybe not days, but more like the Genesis account.

So look what I found out!..........





Speed of light
From Wikipedia, the free encyclopedia
The speed of light in a vacuum is denoted by the letter c for constant or the Latin celeritas (speed). The speed of light through a transparent medium (that is, not in vacuum) is less than c; the ratio of c to this speed is called the refractive index of the medium.
In metric units, c is exactly 299,792,458 metres per second or 1,079,252,848.8 kilometres per hour. Converted to imperial units, it is approximately 186,282.397 miles per second, or 670,616,629.384 miles per hour. Note that this speed is a definition, not a measurement, since the fundamental SI unit of length, the metre, has been defined since 21 October 1983 in terms of the speed of light—one metre is the distance light travels in a vacuum in 1/299,792,458 of a second.


Researchers use super-cool goo to dramatically slow speed of light

BOSTON (CNN) -- The time-honored phrase "faster than the speed of light" might have to be reworked, thanks to the work of a Danish physicist.

By shooting a laser beam of light through a super-cooled glob of a kind of optical molasses, Lene Vestergaard Hau and her team at the Rowland Institute for Science in Cambridge, Massachusetts, were able to slow the speed of light down to just 38 miles per hour -- not even fast enough for the slow lane of a freeway.

By contrast, the normal speed of light in a vacuum is about 186,000 miles per second -- 20 million times as fast.

"I would probably not call it God-like, but I would probably say ... we are tampering with nature in a very peculiar, very bizarre way," Hau says.

The research, conducted at the Rowland Institute and Harvard University, was reported in Thursday's issue of the journal Nature.

The substance that slows the light, called Bose-Einstein condensate, is a microscopic glob of atoms slowed to almost absolute zero -- 459.67 degrees below zero Fahrenheit, the lowest temperature theoretically possible.

Researchers believe that it may be possible to slow the speed of light even further, by a factor of 1,000.

"A human could move faster than that" says Stanford University's Steve Harris, who participated in the project. "But a human couldn't move through a Bose-Einstein condensate, I'll tell you that."

Researchers believe learning how to slow light could eventually have a number of practical applications -- improving computers and communications devices, making television displays and laser light shows more vivid and creating better night-vision goggles.
