Resuming from the next chapter, which is dedicated to cosmic microwaves. If we go with Big Bang Theory then all matter was initially in a highly condensed state and the universe was very very small. It’s hard to visualize this because a second into the life of the universe it was the size of a golf ball but at the same time there was no space outside this ball. We can’t imagine the whole of space being inside a golf ball because such definition of size is meaningless without relation to other known objects, such as the size of a golf club or tennis ball or a ping pong ball. In standard model of cosmology the universe is infinite in size so how could this infinite space be all packed inside a golf ball?
If we were present then, would it mean that all other things we compare golf balls to were still relatively the same size as our golf balls compared to the current universe? What difference would it make from the “insider” perspective then? We can say that our universe is a size of a golf ball to someone who is outside of it now. Besides, how could the space become infinite if it was very finite in the beginning and only a finite amount of time has passed?
Talking about size in this way makes no sense. There’s “observable universe”, however, which ties the size of it to the speed of light – how far it can go in 13 billion years could be considered as size of the observable universe. Then we have to consider that during this time the universe has been expanding so we add that and come to a current estimate for the diameter of the observable universe to be 93 billion light years (as light goes in the opposite direction as well).
Does it stretch any further but we are unable to see it? Possibly, that’s why we talked about “observable universe” here. Now, to the book.
As universe was rapidly expanding after the Big Bang scientists estimated the effect on light emitted at that time and predicted that it must come to us with a significant red shift and, because the matter that emitted it back then does not exist anymore, this radiation must not have any other attributable source. This has been experimentally confirmed as Cosmic Microwave Background, CMB, and so now we have “proof” of the Big Bang.
The author points out to current need to postulate dark matter and dark energy as throwing a wrench into this theory. What if this cosmic background radiation is not a vestige of Big Bang but is emitted by currently existing dark matter? It would mean we need another theory instead of Big Bang and in that theory the need for dark matter and energy might not even exist so in the end we are left with doing what we are already doing because alternatives are scary and unthinkable.
The book then takes us a chapter back and reminds that in semantic theory wave frequency can be correlated to the level of abstraction of the information – higher frequency means more energy is transmitted by a hotter object and lower frequency means the object is cooler, and from thermodynamics comparison discussed earlier it would mean that lower frequency is more abstract while higher frequency is more detailed. What science calls a redshift, therefore, means that the object has shared all its contingent information and only abstract information is left.
Next step is understanding that objects carrying abstract information must be below the threshold of our senses – like we can’t directly perceive our minds or egos. When science can’t attribute CMB to any known object it simply means this object is more abstract than what we can sense, or is “subtle” in the language of Krishna consciousness.
CMB itself is an effect of an imperceptible cause and, because it’s relatively abstract, it affects more abstract “atoms”, too, and not the “details”. These abstract “atoms” are what our detailed bodies are built from and so to us it would appear that effect of CMB is felt “everywhere” rather than in any specific part because perceptible parts of our bodies are built of “detailed” atoms contingent on more abstract “atoms”.
When we receive this abstract information and only our abstract “atoms” are affected by it then all contingent details change at once, too, and that means we can’t pinpoint the direction from which this radiation comes from – just as we can’t with CMB. As I understand it, direction can be deducted from two changes happening one after another in distinct locations but when the entire contingent body is affected at once this becomes impossible, so we say that CMB comes from “everywhere”. This all will start fitting together very soon.
The author then makes a detour into quantum mechanics and says that instruments measuring CMB must be treated as quantum systems and not typical physical objects. I can’t follow that but the point is that without quantum measuring systems we only catch the quantity of information but not its type, which is compared to examining a book without knowing language and having no clue why squiggles of funny shapes appear seemingly randomly in it. I don’t want to delve deep into this here as it was all making sense before and will continue making sense after this one paragraph.
The principle under consideration is that when the system receives abstract information the state of all contingent details is changed at once. This means that energy transmitted with low frequency will be absorbed and assimilated faster by the whole system while higher frequency energy will affect big changes in only selected detailed parts. Apparently thermodynamics confirms this, too.
It’s not immediately obvious to me but the author claims that there’s not only a different semantic explanation for common observable data here but a new kind of predictions, too. It would be nice if it was explained what kind of predictions and in what areas he envisioned here but he skips to the next part, which refers to Doppler effect from a few chapters back.
Doppler effect, if you remember, also produces a redshift and in light of today’s semantic explanation it would mean that we receive a more abstract information. This has an effect on our understanding of sources of light when we think it’s emitted by hydrogen or helium atoms found on this planet – because these atoms are detailed constructions we built from our observations and not more abstract “atoms” which produce the observations. Meaning that instead of looking for a more abstract source to observations we create a contingent. Hydrogen atoms we think up here can’t that more abstract source. There’s no sound reason, therefore, to extend our interpretations to the rest of the universe and we should rather accept that redshifts are produced by a different kind of sources then the ones we have on Earth.
Now that we have both CMB and Doppler effects explained semantically there’s no reason to accept Big Bang theory anymore. The universe is not expanding but static and is made of objects of a different, more abstract type then the ones we have on our planet.
Let me see if I got this right – we believe in Big Bang and expansion because we observe redshifts in radiation but semantically it means that it is transmitted by more abstract types of matter than we experience here, like cosmic mind and cosmic intelligence. Makes sense, but lacks detail, but not to worry, there will be plenty of chapters discussing “subtle” influences on our world later on.
