no,infact there have been many debates on the subject.according to Einstein,speed of light changes with gravity

There's no way to know if it has always been constant, but there isn't any reason to suspectit hasn't been. We've had high precision measurements for about 40 years, and it hasn't budged by any measurable amount in that time period. Creationists often use measurements dating back to the 1800s to 'prove' the speed of light has been decaying.
First off, those measurements were absolute crap, and should only be regarded as estimates rather than real measurements. Second, even for people who don't understand the concept of measurement accuracy, those measurements do not show a trend, and certainly not the exponential trend creationists claim.
If there was a measureable change over the last 150 years, there would also have been a measureable change over the past 40 years.

Yes That is the speed in vacuum.
The light bends ( the direction change) due to gravity . But do not change the speed.
I want to see any of your experimental data based on which you propose this?
Because you have an Internet and computer don't insult the bright minds in the world. If you are a creationist your best bet will be hide behind the "Faith" defense.

at first, the length of the cost is the observer who sees the cost of the spacecraft being only below the cost of sunshine (i.e., on the launch internet site), no one on that spacecraft. He additionally sees the spacecraft recent technique somewhat extreme mass, length and time dilation. So, while he sees the intrepid astronaut hop on his bike, he sees that throughout the time of very sluggish action, and the cost he sees, one hundred eighty mph or which you will desire to the astronaut, is only a tiny fraction of the 10mph required to interrupt the SoL. So, no, the observer sees only a motorcyclist making a bare develop over the spacecraft itself. Worse, it is going to become an excellent smaller fraction the faster the spacecraft is going, and the faster the bike is going, it procedures the cost of sunshine by using an incrementally declining share of the the rest velocity required.

The speed of light is 300,000,000 mts/src in vaccum. It is less in other transparent medium say glass etc

No in the late 70's the government reduced it in order to conserve energy.

its only that speed in a vacuum... in air its a little bit slower

nah, when light was young it was alot faster, in its old age, light has slowed down
