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.
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?
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.
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.
