Red shifting of the light coming from the distant galaxies

 

What is red shifting the light coming from the distant galaxies? Since it was studied, we know that the more a galaxy is far from our own galaxy, the more its light is red shifted. But why?

 

 

To red shift light, what has to happen is, that the light is "now" covering more space in the same time, that "once" when it was emitted. We kind of know that for sure. But, how is it possible?

Today, we interpret that with the idea that the universe is expanding, which leads to the idea of a past Big Bang where everything started: space, time, energy and matter.

But, what if it was a wrong idea? Not a very wrong idea, but more a bad interpretation of a phenomenon that would be simpler than we thought?

 

 

Gravity is all around us, because of the mass of the Earth, the Sun, and our Galaxy. We can't escape it, it's a part of the point of view that we constitute. So when we look at distant objects, what happens is, that our own gravity field is transforming the image we get.

Gravity accelerates light and everything else coming to us, in a way that the more things arrive from a great distance, the more they are accelerated.

But, as you probably know, light can't speed up, its speed is an absolute constant in the universe, for any point of view. So, what's an accelerated light wave, if its speed can't change?

 

 

Well, it's a red shifted wave of light...
