So according to you guys the universe is consistent forever as our visible universe? does the universe have any type of shape? The 'wit' you use to make your answers more ridicule for some of this 'empirical knowledge', raleigh scattering and this, it would create quite the lark!

Do you think anyone here actually said anything like that?
If you do, please quote it because I'd like to know what it is you misunderstood.

That's not a sentence.
What did you think it meant?

I'm not sure what you mean by that question.

does the universe have any type of shape?

It seems to be flat, if you'd consider that a shape: https://www.astronomy.com/science/what-shape-is-the-universe/

What is that image meant to show us?

It's an image of galaxy's with red shift. I notice that they seem to be glowing red. I've had to much to think already. I'll take a shot at it later.

Maybe they just are red.
That picture does not tell us anything.

What causes gravitational blueshift?
Energy is transferred to the light wave when the light wave propagates towards the gravitational body, resulting in that hv and v increase, i.e. blueshift. Energy is transferred from the light wave when the light wave propagates from the gravitational body, resulting in that hv and v decrease, i.e. redshift

This answer is out there but not a single juxtaposition of the idea of the sky being blue.

[trevorjohnson32 (OP)]

What we now call gravitational redshift was first proposed by Einstein from his thoughts in the development of general relativity. Einstein predicted that the wavelength of light coming from atoms in a strong gravitational field will lengthen as it escapes the gravitational force.

Because it's not the reason why the sky is blue.

So the light entering a gravity is blueshifted, there's plenty who would argue yes. What makes you believe the light entering earth from above would NOT experience this blue shift?

[Kryptid]

Blue shift doesn't literally mean that it makes the light blue.

[paul cotter]

As I have said previously if earth's gravity was sufficient to shift part of the light from the sun to blue then why is it not all blue? The op appears to be immune to reason.

We know how much the earth's gravitational field changes the wavelength of em radiation.
https://en.wikipedia.org/wiki/Pound%E2%80%93Rebka_experiment
And the effect is tiny. About 1 part in 1000000000000000
It's almost impossible to measure.
So it can't be responsible for anything as obvious as the colour of the sky.
Also, we know how gravity affects different wavelengths and teh blue of the sky doesn't have the right spectrum to be due to blue shifting.

Why are you still flogging this dead horse?
Are you not clever enough to understand the logic involved?

None of those answers proved anything, they look like whimsical thoughtless responses. I do like Paul's a little though.

Actually Ralley burger cheese racing is what causes the sky to turn orange at sunset. It's when the giant ball of cheese in the sky starts leaking. It goes along with the raleigh thing

It's almost as if you are simply ignoring them instead of understanding them.

they look like whimsical thoughtless responses.

So you think that blue shift literally means that light turns blue?

You think that a gravitational blue shift factor of "about 1 part in 1,000,000,000,000,000" can be detected by the human eye? By the way, here is an example of just how tiny that factor is. A red photon has a wavelength ranging from 620 to 750 nanometers: https://scied.ucar.edu/image/wavelength-blue-and-red-light-image#:~:text=Red%20light%20has%20longer%20waves,around%20620%20to%20750%20nm.

That would be a change in wavelength of 6.2 to 7.5 x 10^-13 nanometers. So that would be a decrease from 750 nanometers to 749.9999999999999 nanometers or 620 nanometers to 619.9999999999999 nanometers. Now why don't we compare that with the blue shift factor caused by movement (the Doppler effect)? https://keisan.casio.com/exec/system/1258042695

A 750 nanometer photon emitted by an object travelling at 8 kilometers per hour is blue shifted towards an observe to 749.9999995 nanometers. That is a larger change in wavelength than what the Earth's gravity provides. Now let me ask you, does a person look noticeably bluer when they jog towards you? If the answer is no (and I know that it is), then the sky isn't going to look bluer due to gravitational blue shift either.

Why are you still trolling? I cannot understand what's so hard about acting like a mature adult. Consider this strike two. Three strikes and you're gone for good this time.

They didn't prove anything to you and they look whimsical to you, because you don't understand them.
We know why the sky is blue.
We know that it is impossible for it to be gravitational blue shifting.

If you can find a reputable source that says the sky is blue because of gravitational blue shift, then let us know.
Otherwise stop wasting bandwidth and time.

Is the sky black on the moon because there is no atmosphere to create Raleigh scattering?
