Hubble Ultra Deep Field - Horizon Zoom

What's really in a tiny, "empty" fraction of our sky? Looking back approximately 13 billion years (between 0.4 and 0.8 billion years after the Big Bang), the Hubble Ultra Deep Field gives us a glimpse into the early universe, as well as a sense of the universe's mind-bending size.

I couldn't find a video on YouTube that truly gave a sense of just how small a section of sky the HDF comes from, so I made my own.

this so fascinating... think that is just a small part of what you can see on the entire sky and on the other side ...

I would be so alone and scared out there, but at the same time so happy and in awe

I'm not completely sure you get the full implications of this. Unless I'm wrong, this is how I understand it. The Hubble deep field is pointed at a patch of sky with more or less a whole lot of nothing in it. Therefore, it's going further in distance than we've seen before, or at least seen clearly. Therefore, it's also going further back in time since it's so far away. Therefore, it's from a time when the universe was more densely packed together than now. If anyone knows about this stuff and I'm wrong, please correct me.

The Cosmic Background Radiation Ambient Noise map shows us the density of galaxies when we observe the universe from the earth. There more galaxies in red spots and less in the dark areas.

the noise is not the left over of big bang, but the collective noise of galaxies. see Hubble's UItra Deep Field. When James Webb telescope is ready, we can find a black spot in Hubble's UItra Deep Field to have long long exposure picture, what we will have is Webb's UItra Deep Field, repeating Hubble's UItra Deep Field patent.

The big bang is very suspicious, to me, the redshift is caused dark matter and dark energy, not by galaxies moving away from each other. If the universe were expanding faster and faster, galaxies would move away from each other, at one point, galaxies would stop collations. But the collations happened, are happening, and will happen for ever.

The arms of a galaxy indicate how many collations that galaxy has gone through. No arm means original galaxy. The arms and sub-arms numbers (N-1) tell us how many collations that galaxy experienced. Two arms, one collation. Two main arms, one of them with a minor sub arm, three collations; formed by one galaxy and one galaxy had prior minor collation. The galaxy can't grow infinitely, when the mass go beyond certain amount, the core will explode.

The universe is isotropic. To the people live at the end of James Webb telescope can ever reach, think that we are as old as we thought they are.
