While watching an older show on disc sci I wondered at the fellow saying "..light always travels at the same speed. You turn on a flashlight at mach 3 or standing still, it still travels at the same speed" WRONG. doc
And another .. "you cannot travel at the speed of light. Your mass would increase to the point of infinity ..." More B.S.
In the first case, then why does doppler shift show up when viewing distant stars and galaxies?
Second, if that were true. the photons leaving the sun would instantly become black holes and we would not be talking about this.
I shall devulge the answer soon after I determine why it's okay for my friend to say he likes big girls, while it sounds bad because I prefer little girls. That is to say petite. pretty and hell, street legal too! stripes not included.
say what, Ed? LOL ...

In 1905, Albert Einstein postulated that the speed of light with respect to any inertial frame is independent of the motion of the light source, and explored the consequences of that postulate by deriving the special theory of relativity and showing that the parameter c had relevance outside of the context of light and electromagnetism.
he expressed these postulates as:
The Principle of Relativity – The laws by which the states of physical systems undergo change are not affected, whether these changes of state be referred to the one or the other of two systems in uniform translatory motion relative to each other.
The Principle of Invariant Light Speed – "light is always propagated in empty space with a definite velocity [speed] c which is independent of the state of motion of the emitting body." That is, light in vacuum propagates with the speed c (a fixed constant, independent of direction) in at least one system of inertial coordinates (the "stationary system"), regardless of the state of motion of the light source.

The derivation of special relativity depends not only on these two explicit postulates, but also on several tacit assumptions (made in almost all theories of physics), including the isotropy and homogeneity of space and the independence of measuring rods and clocks from their past history.

Readers digest version:

C exists only at the "Physics Store" in an ideal space/time universe.

We do this all the time when studying complex systems. Your mileage may vary.

Hi all.

Rotor--don't know what you're talking about. C is where it's always been--right there between B and D.

Oh yeah--it's in my alphabet soup bowl too....

Good morning ladies.

A little sun in my world today, not that it's warming anything up, but it's nice all the same.

Hi Rotor. 50 degrees today, 70 by Sunday. I could handle weather like that all winter.....

Afternoon to all. Sunny here too,after a frosty start to the day. Calling for 50/60 thru the weekend,lows at night to be around 40's.

By popular vote Rotor gets all the snow stuff.

Hey Rotor, I knew you would have something to say about that. True, physicists need a constant to work from, often times they invent one. Bubbles, string theories, parallel universes,etc.
Getting back to Einsteins theory, if light speed is constant, the formula doesn't play out. One cannot square the speed of light. Much less multiply a given mass by it then squaring it.
Might just be why they can't build stuff to find these things.

There ARE more important things in the world--like my new dress--do you like it?

You know, it's difficult to find formal evening wear in cammo.....
