Like Effect

[foodchain]

So the universe is growing if I understand things. Well maybe space would be a better word? I read up on stuff like hubble and they find the idea that the universe is accelerating because C is always constant in a vacuum right or in space at least until a medium is contacted if I have my understanding correct. We can also gauge the age of the universe to say 13.7 billions years right? Yet the age compared to the speed of light is what shows the acceleration or growth of space via things like redshift correct?

 

I just don’t understand something. Spacetime is to warp via GR which is gravity right. So does this impact the growth at all? IS this acceleration due to effects like false vacuum states possibly? I mean could such be remotely visible via warping effects? I am just wondering because if space can accelerate or move faster then light would this have any impact on light such as how its bended by the warping of spacetime itself? Could this partly be the effect supposed by dark matter and or energy?

I'm not quite sure what you mean, but I shall attempt to clarrify some points.

 

The universe is expanding, and this expansion is accelerating.

 

This expansion is not limited to speeds less than the speed of light.

 

We know the universe is expanding because the light from the majority of galaxies is shifted to show they are moving away from us.

 

Mass curves space time which causes gravity. The gravity of everything inside the universe was believed until relatively recently to probably be decelerating the universe, but it is not, this is due to some reason we don't understand labelled dark energy.

 

Yes I can see how it would have an effect, but I am not well enough versed in astrophysics or general relativity to really answer that with anything other than my own speculation...
