If its being absorbed and reemitted than it is going slower. Because of the nitrogen, hydrogen, and oxygen gases that make up 99 percent of earths atmosphere than the process of absorption and emmision is always. Those gases and process arent changing so light is consistenly slower on earth.

In explanation of what seems to be my constant work error. G is the universal constant but g (gravitational acceleration on earth) is a constant tht never changes in earths atmosphere. So all the matter of fact individuals out there I was still right in my example. Guess I will have to be more literal

Obviously u didnt read the whole section cause i argued for light being a constant and explained why. Now ask any physicist, light on earth travels a bit slower than light in space.

You r absolutely right in light being a universal constant, but just as gravity is a universal constant it deviates depending on its enviroment. Like for instant the gravity on earth is 9.80 meter per second sqr and gravity outside of earth is 6.673 times ten to the negative 11th. They are both constants in thier field of use. So the same principles apply to light. In the vacume of space its such and such speed and in the atmosphere of earth its slightly slower. Now the effect of the speed of light on earths atmosphere is so tiny tht it will not affect any experimentation or any mathematical calculations if you use the 186000 miles per sec number. It takes sohisticated instruments to calculate the difference and the difference really does not effect anything. Also the slight deceleration of light on earth is still faster than anything in the universe and nothing comes close. Also it being a constant means its not gonna fluctuate in its enviroment its gonna stay the same speed.

Anything before the big bang and the point of singularity can not quite franky be explained. Because the mathematics of general relativity break down, and obviously you can not do an experiment, but from what we do know about the big bang and singularity points there are some very credible ideas. For one since space-time started at big bang then its logical to view time at a stand still before the big bang. All the laws of thermodynamics and special relativity do not exist because time as a whole does not exist in essence nothing is moving not even the smallest subatomic particle, but also there never was anything to move to begin with. To conclude imagine the area before the big bang to be an infinite abyss of darkness.

The speed of light has always been known to slow down depending on its gravitational enviroment. The speed of light is slower on the earth, albeit it very very small rate of deceleration, than if it were moving through a deep void in space. Also think of a black hole event horizon, once anything including light crosses that god forsaken line nothing can escape and time itself is slowed down. So one can only speculate that light itself is slowed tremendously inside the black hole.
