So this is not the new idea.

What is the new idea?

And your friend thought this was not being considered? The observable universe has a radius of about 46 billion light-years. 46 > 13.8

We’ve known this for quite some time.

How much time? when was it first published?

It was figured using the Hubble Constant, which he published in 1929 but was based on earlier maths and observations by lots of other luminaries of the time.

That's not correct, Edwin Hubble calculated 280 Million Lightyears.

The 94 Billion (diameter) is since 2006 (with my, ehm my friends explanation). However I do have a CNN news article about it being 156 Billion Light-years across. this was May 24 2004.

I have a forum post with this explanation from May 22 2004. I mean the explanation like above, no calculations, I can't do that. We aren't even sure about Hubble's constant so it is hard to calculate.

I said his law is used to calculate the radius. Over time our data has improved, and so has the calculation.

A FAQ I saw that showed the observable size was dated 2005, but the knowledge dates back to the 1990s. Prior to that the error bars on the expansion rate and age weren’t conclusive, but the possibility that the size was larger goes back to the 1950s-60s when decent estimates of Hubble’s constant were made and the CMB temperature was measured

Well ok then, I posted my idea here, let us see what happens.
