So it cannot be possible because the space among the clusters is mostly vacuum, isn't it? But is the structure on large scale similar to a net? Thanks for clearly answering.

But the intergalactic medium is isotropic on large scale, like the distribution of galaxies. And there are anyway anisotropies in the CMB, isn' t it?

No things to say?

Yes, but the sum of all the photons that arrive from everywhere to the intergalactic medium could warm it to the emission in the microwaves. Or not?

I refer to the radiation from intergalactic medium. A body at that temperature must have a black body spectrum, and it is a 3 K matter spectrum, like the dust among the galaxies. Is the dust emission quite powerful to emitt that radiation in the microwaves?

which are the differences of the spectra of H and He ionized?

I' ve read that the CMB could be emitted by intergalactic medium. What about it?

which are these evidence against his ideas gathered in the last few years?

What about the Arp' s theories? I' ve seen the photos of the Stephan's quintet. What about them? Seems that the quasars are near other objects that look to be nearer to us than the quasars.

In a condition of high pressure, how could vary the Helium emission spectrum? Is this spectrum modified from the pressure?

I heard that dark matter could be the CMB mass corresponding, but I am not satisfied from that. What about this?

Could we ionize He also if it has the biggest ionization energy?

I heard there are many alternative hypoteses for cosmological redshift, e g Fred Hoyle' s variation of mass and tired light. There are other ones? Thanks.

Where could I find the spectra of most elements on line? I would expecially the He 2 spectrum, the Be and the B ones. Where could I find it?

I would say a/b+x.
