How does reality come out of something so shaky and so unreal?
...therefore the basis of reality seems very elusive, quicksand-like and unstable yet out of this we experience reality and our physical world. How does reality come out of something so shaky and so unreal?
How do consonant and vowel sounds create words and a whole language so that the words seem to extend or emerge from objects rather than just being labels i.e if you break down the word 'bottle' - 'boh tuhl' you see how it is meaningless, but the word itself 'bottle' intensely evokes the actual object even to the point where the word looks like the object and the object looks like the word. Or maybe that's just me being weird?
Or, regarding money how did a system become so integral to our existence and so 'real,' when it itself is just a concept and not worth the paper its written on literally - a £20 note is worth much less than £20 regarding the paper and ink. And yet the unreality of money has extremely real, life or death, implications.
But just how does reality emerge from unreality and how can we trust reality if it has such a shaky foundation? For me reality never felt very real anyway.
The universe happens. We try to describe and predict it by various scientific means. Nobody claims to have a complete description or a universal means of prediction. So what? It's hardly surprising since the universe is a very big place full of very small things, and we have only been doing recognisable science for a few hundred years, during which we have at least convinced ourselves that the universe is inherently not infinitesimally predictable.
For example it's currently accepted in mainstream cosmology that the universe is probably flat. Given that and the cosmological principle which states that the overall density of matter on a very large scale is uniform throughout the universe then the universe is both infinitely large and has an infinite amount of matter in it.
Pete, obviously you believe this, and I am certainly not qualified to challenge your belief. However, it does appear that not all cosmologists are of the same opinion.
For example it's currently accepted in mainstream cosmology that the universe is probably flat.
The current best fit model is a flat ΛCDM Big Bang model where the expansion of the Universe is accelerating, and the age of the Universe is 13.7 billion years.
The primary goal of these experiments was to measure the angular scale of the first acoustic peak of the power spectrum of the anisotropies, for which COBE did not have sufficient resolution. In 2000–2001, several experiments, most notably BOOMERanG found the Universe to be almost spatially flat by measuring the typical angular size (the size on the sky) of the anisotropies.
Scientists believe that we live in a spatially flat universe whose expansion is accelerating due to the presence of dark energy; ..
This does leave those of us who are not experts wondering what to believe, who to follow.
Why do you feel a need to believe something like that is definitely true or not. What you can rest assured on is that there is a very large probability that the shape of the universe is flat.
Time is also quantized and has the properties of the wave and the particle.
Quote Time is also quantized and has the properties of the wave and the particle. Jeffrey, do you know something we don’t? This is something I would love to have more information about, but most of what I can find seems to be a clear "don't know".http://www.scientificamerican.com/article/is-time-quantized-in-othe Is time quantized?“The brief answer to this question is, 'Nobody knows.' Certainly there is no experimental evidence in favor of such a minimal unit. On the other hand, there is no evidence against it, except that we have not yet found it.”
