Expansion of the ether?

Hello everyone. After I ask this question, I wonder if anyone could point me to some sites that get in depth with my question. As I don’t have too much knowledge on the subject.

I have heard and read that the universe is expanding. And that scientist come to this conclusion because the light from the stars are in the red spectrum. But, what if the stars are stationary (relative to us) and it’s really the ether that is expanding and that is whats distorting the light waves to make us believe time is measured in distance.

I’m really new to all this, and am finally trying to look beyond the horizen. Thank you for taking the time to read this post. Have a good one.
