2. (At around 59:00 in the Video) It appears that cosmic radiation is pointed towards us in a way that would appear different if we moved away from
our solar system. In particular cosmic radiation seems to be in the same plane as our solar system -- aligned with our orbit around the sun. It seems
impossible. but they explain it well.
There are papers that attempt to explain this.
Some of the possibilities explored by This Paper
is about local effects -- namely that the known
foreground microwave radiation in our our solar system was not properly subtracted from the results, and thus appear as part of the CMP. A similar
potential explanation in this paper is that there is still un
known local microwave foreground radiation that had not been subtracted from the
data, and is thus included in the background radiation data.
3. (At around 53:00 in the Video) it appears that galaxies exist in concentric rings around our galaxy, and if we moved off of our galaxy to
some other point, it would look different to us. If that is true, then it is very hard to explain how that would be unless our galaxy (at least) was
at the center of the universe.
It's true that our local cluster of galaxies does have a structure that may not be seen from other perspectives. However, the observable universe is
vast, and many many such structures exist around other local groupings of other galaxies. However, if we were to move 10 Billion LY across the
universe near another of these local clusters of galaxies, we would see other localized structures unique to those clusters.
5. A secondary point that I really latched on to was the concept of living in a "Fine Tuned" universe -- where if even one small constant was
off (gravitational constant, speed of light, etc.) things would completely fall apart. There is an incredible precision to the universe that is not
explainable. Why is everything in the universe tuned for life on our planet?
Well, it seems lore likely that life is fine-tuned to the universe in which that life was able to exist in the first place. I mean, how could the
universe give birth to a type of life that could NOT possibly exist under the laws of physics in that universe?
We are able to say the universe is fine-tuned for life, because we ("we" being the general type of life in this universe) were the type of life that
COULD arise in this universe, given the parameter of the universe.
In another potential set-up of physical laws in a universe, perhaps matter would organize itself very very different -- for example, let's say that
neutrons and protons would interact differently, causing an unimaginable type of thing analogous to the atoms in our universe, but not the same as our
atoms. Or something something other than what we call the strong nuclear force holding atoms together. There might still be something analogous to
the strong nuclear force, but it might be unimaginably different...
...A universe such as that would be a place in which we (again, "we" being the general type of life that CAN exist in this universe) could not
given the laws of physics of that universe. However, that does not mean that some other weird type of life could not emerge in
that unimaginable weird universe -- life that could not possibly exist
in our universe due to the laws of physics here.
If that were the case, then life in that universe could be ALSO saying "Isn't it stage that our universe seems fine tuned for life".
again, the reason that weird and different universe would seem fine tuned for THAT life is because THAT life is the type that the physical laws of
that universe allows for.
Another analogy would be the oceans on Earth. A fish in the ocean might think (if it could think) "isn't it strange that the oceans are built
just right to allow us fish to live; it appears fine-tuned for us fish."
Granted, that would seem true, but again the reason the fish
developed to be able to thrive in the oceans in the first place was because of the physical parameters of the oceans allows specifically for animals
such fish evolve in such a way that they could thrive. Take a fish on land, which could be thought of as another universe (in a broad sense), and
that fish would not survive. Similarly, take a human 1000 feet underwater, and the human would not survive long.
That's because the type of life that could
evolve i the oceans would be fine tuned to the oceans, and the type of life that evolved on land
would be fine-tuned to land.
I say the oceans are another universe only "in a broad sense" because the laws of physics on and and in the water are the same (unlike two different
cosmological universes with vastly different laws of physics) -- but you get the broad analogy, and my point still stands.
