Default What was the width of the visible sound-horizon at the birth of the CMB ?

I read:

[ Planck_Surveyor ] will lead to more accurate estimates of
the distance to the last scattering surface
and of the size of the sound-horizon at last scattering.

What are the current estimates ?

Whats this, something Professor Relf (B.Wiki) doesn't know?

Hi T_Puddleduck, I read:

the distance to the last scattering surface
and of the size of the sound-horizon at last scattering.
www.RSSD.ESA.INT/SA/PLANCK/docs/Bluebook-ESA-SCI(2005)1_V2.pdf

and I asked: What are the current estimates ?

and you asked: What's this, something Professor Relf (B.Wiki) doesn't know ?

No, it's something that wasn't in your text books, hence you don't know it.

Jeff, You really are a complete moron. Stop trying to play with the big
boys. You've been spnaked already. Why should I educate you anymore
when it is obvious you don't know the basics.

Please post your physics qualifications ... You may include any high
school projects if you wish.

My Honours degree laughs in your face.

Anyone can do a google search and see how you fail to understand basic
cosmology, you maroon......

Still think 380,000 years is the WIDTH of the universe ?

http://groups.google.com/group/sci.p...4f1673f7d98696

Here's a clue. Ask any cosmologist - they'd laugh at your stupidity.

Ha.

Remind me again how _any_ of your crackpot theories work. Do you still get
your rats pregnant? Have you explained how five spatial dimensions can exist
given the evidence for three? (Etc.)

I'll give you a clue.

I've already told you it before.

Remember the anisotropies - well we discussed the first peak. Its
directly related to the horizon problem... in fact, the difference
between the anisotropies we see and the distance we expect is one of
the main tenets of inflation.

Default The width of the visible universe has _Nothing_ to do with it's age.

Hi T_Puddleduck, You _Claim_ to know:

1. The width of the visible sound-horizon at the birth of the CMB.

2. The Comoving_Distance from earth to the birth of the CMB.

Yet I've seen no numbers from you other than this bizarreness:


Google.COM/group/sci.astro/msg/7edd934e13cb2c37

The width of the visible universe has _Nothing_ to do with it's age.
I already know that the universe is now 1,088 times cooler,
and so 1,088 times wider.
But, at the birth of the CMB, the cosmic horizon was near zero,
because that was the first visible light.
