then how could radio waves from then still be heard?

Because the radio waves kept going until the reached the end of the Universe , and then bounced back. They kept bouncing back and forth between the original 'center' of the Universe (where they hit each other and rebound) and the end of the Universe, which is hard like a turtle's shell.

That is how they will be able to still 'receive' the radio waves, even though they are very, very weak by now. That's why it takes such a big radio-telescope.

Huh? It's all one big giant ball and we're on the inside? What happens when solar systems start crashing into the "wall"?

I thought it was because the Universe is finite, isotropic and expanding, at least according to current theory. The radiation from the big bang is trapped in the finite Universe, as the Universe expands their wavelength increases and they are absorbed by interactions with dust and gas and become increasingly faint.

This array is only planned to be the largest radio telescope, as measured by aperture, not baseline or resolution. It is not the largest telescope in the world yet. It's an interesting instrument. I wonder if the Caliph of Europe will find it to be an infidel perversion and dismantle it, as the Caliph of Egypt did to the library at Alexandria.
