Well, even in basalt surfaces in lava tube caves, which are a by product of volcanic activity, we find these walls totally covered, in many cases, by these beautiful, glistening silver walls, or shiny pink or shiny red or shiny gold.

Dark matter potential wells are still collapsing, forming the first cores of galaxies, and clusters of galaxies.

And, we can also see where the galaxies are.

Redhead, redhead.

And every time there's a galaxy at its location there's a galaxy and if we know anything about the galaxy, which we do, because there's a redshift measurement and everything, you put in the type of galaxy and the color, so this is the real representation.

By mid 1990s there was a good catalog of infrared selected galaxies from the all sky survey by IRAS satellite.

And here is an example.

Baby. Baby.

Gerard de Vaucouleur in particular, noticed what we now call the local supercluster and more and more galaxy redshift surveys were conducted.

What bank?

Bank?

Gold, silver...

That produced fairly unbiased set of galaxies that enabled astronomers to go deep into the zone of avoidance.

Clusters are now known UNKNOWN of maybe 1 and a half or so, and there are hints of cluster like structures to much higher that you see it. . But this is one of the most distant clusters proper that we know.

When going by their initial success, the Center for Astrophysics conducted a second generation of redshift survey which compiled the redshifts of about 25,000 galaxies.

That is as far as comoving coordinates are concerned, but, what if the object is fixed in proper coordinates, say like a galaxy?

The net effect of that is that the filament looks thinner in the radio direction than it really is.

Start differentiating into effector and memory cells.

Red. Ok, how about Green, no no!

large supercluster, but it is the one in which we belong.

And nowadays, the way this is done is the galaxy map on the sky, projected density map of the sky is smoothed and Algorithm of some sort is used to identify the other densities.

Red eye, baby. Still the red eye.

I'm in banking. In banking? How'd you get into that?

If you add up two multiples of three you always get another multiple of three( which is the sort of fact you use everday in math class)

So in part of this negotiation process

Let's call this Bank A.

And let's say that Bank A

BANK OF VENICE...

Yes. Banking section.

Which bank?

It's a bank.

The Coral Galaxy!

Huh?

That's a lot in common.
