c constant right thinking how photons from Sun take 200,000 years to
reach Earth Trebert


*** Once they escape the grip of Sol, the trip takes
around 8 minutes.

Why would you assume they take a straight path out? They do not.

Leaving Sun's surface 8 minutes leaving Sun's core comes under Heisenberg Principle. That means most photonbs take 200,000 years,and they never slowed down. If photons slowed or bounced it would be big problem. Imperial thinkers just don't think. Go figure TreBerts

Lab at MIT in Cambridge used sodium at 3.7 k to slow photons to 3 mph. O Ya I know why they needed such cold to give this measurement. They just don;t think distance. They think onlt time. They don't get the picture.. Think man think. TreBert

Wouldn't it just make things a whole lot simpler to redefine the

kilometer as 1/300000 of c?

*** Just for doofi like you, AA, from my Lagoon to your dumpster,



The definition of the Meter and by extension, the KM:



http://physics.nist.gov/cuu/Units/meter.html



If you still don't get it, ask HardBlow ... he knows everything.



From you source:

"In turn, to further reduce the uncertainty, in 1983 the CGPM replaced this latter definition by the following definition:

The meter is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second."

You see, they should have just said, "1/300 000 000 of a second." Nice round number!
