Real Universe and Observed Universe

[alpha2cen]

We observe the Universe through the telescope everyday. Is the scenery a mixed past Universe?

How do we know current Universe or Universe change?

 

model

Real Universe: beginning -------very old past-------old past ------------ past------------near past -------present -----------------------future

Physical lag : light speed, distance, time, Universe movement, location

Obtained Universe scenery : Mixed Universe (very very old, very old, past) scenery is obtained.

The scenery figure appears differently from the current figure depending on the location of the objects in the Universe.

 

To understand real Universe behavior, we must transform obtained Universe scene into real Universe one by using an inverse physical lag function.

Obtained Universe scene ----> transforming by inverse physical lag function -----> Real Universe scene

 

The real Universe, we would like to know, may be current Universe, past Universe, Universe history, etc.

Well if the big bang theory is correct then we can look at CMBR and cosmological blueshift to see the new universe, while cosmological redshifted light shows us the older universe.

That is an ideal thought. The information we could know is limited. We even do not know even old past about far away star. But, we might dimly estimate the present Universe by using Universe model and obtained data. It would be a 3d map, which contains Universe model.

While there are individual cosmological objects that demonstrate a blueshift with respect to our solar system/galaxy, there is no "cosmological blueshift" in the CMBR - that would imply we live in a contracting universe, and the available evidence indicates that is not the case.

I thought their was blueshifted light but it was only in a line of our closest galaxies?

Andromeda is blueshifted because it's approaching us. Is that what you mean?

[too-open-minded]

Theirs Andromeda and some other known galaxies we see blueshifted, yes. Their all in our local cluster and pretty much in a line coming from the direction of CMBR, I think lol?

Considering the CMBR is everywhere around us, there is no line from the direction of the CMBR. And while we do see, as I said, certain blueshifted objects, these are the exception, not the rule.

CMRR has a blue shift or a redshift, too.

I don't know if you meant to link something else, but what I got from that link specific to the CMBR is this:

 

The standard interpretation of this temperature variation is a simple velocity redshift and blueshift due to motion relative to the CMB...

 

Which seems to me to indicate that the CMB is the reference against which the motion is being measured. Is my understanding incorrect?

 

That being said, I agree that things can appear blueshifted in reference to the CMBR, or in reference to our observational position here on Earth, but things are not coming at us on a line from the CMBR. The CMBR is the background of the observable universe - it doesn't exist at some fixed point in the sky that you could draw a line to and say "It came from that way."

CMBR is a microwave. So, it's figure is affected by observer's the moving speed and direction.
