Hi. If we're are going to discuss any further, I need you to understand that I respect your intelligence. Therefore, I will speak as if I know that you will not be offended.
I started a response to you which became too long for you to read and for me to write, so I'm shortening it. :)
I...

I'm not disagreeing with you and let me ask you:
Does what you're saying agree or disagree with the proposition that while according to the red shift the universe is expanding, it is also possible that at the same time all objects and the space in between them are expanding also?
Ha ha, you obviously are intelligent, so not for one moment would I forget that.
Perhaps I should have said that there "should" be only one definition of the word 'infinity'.
I know and understand what you told me about 'infinity'. And I recognize that everything you said was correct. What...
Of all words, 'infinity' is tied as the most striking example of a word that can have only one definition. For example, I'm sure we all know that the number of integers is not infinite, it is unlimited.
The only definition of infinity which is rational, is 'the summation of all things'...
Hopefully it is obvious that math (and physics) can never tell us about how "things came about", but rather can only be used to describe and predict.
The origin of things, if deducible at all (which it is), is only apprehended conceptually.
Let's call it mental-physics.
For...
I should ask, how do we know that the universe is "expanding"? Is it not the red shift? And of course we make the assumption that red shift means that things are getting more meters apart. But the red shift would still be observable if all things, including space, were expanding, would it not...
I was under the impression that the expansion of galaxies is NOT measured by rulers, but by the red shift. In which cases it would be allowable for the rulers to be getting bigger at the same rate as distances.
But you can't PUT sematics aside. That's a bugaboo. If 'something' and 'nothing' have real meanings, then something cannot come from nothing. If they cannot be ascribed real meanings which can be used to deduce, then mathematics has the same problem.
That's a nice statement by Hawking and crew, but it is intuitively obvious that if "nothing" existed prior to the singularity, then the word 'prior' has no useable meaning. That is a conundrum. Therefore something is wrong with the nice statement.
It appears evident that the smearing out of which you speak, explained by the Uncertainty Principle, is the mother of quantization of length. Due to the uncertainty, no length actually exists until it is defined(specified). Until all possible lengths are defined(unreasonable), then in the only...
Thank you. And then am I to understand that I couldn't have STOPPED the rubber band at any length I so choose, (in other words at one of those transient states)?
Thank you. And then am I to understand that I couldn't have STOPPED the rubber band at any length I so choose, (in other words at one of those transient states)?
Do I understand this?-if I stretch a rubber band from a 1" length to a 2" length...
If I stretch a rubber band from a 1" length to a 2" length, is it true that it was not all possible lengths between 1" and 2" sometime during the stretch?
In other words, at some level, quantization enters in...
Is a change in gravity felt instantaneously on the other "side" of the universe?
That is, does gravity travel instantaneously? Have we ever been able to measure the speed with which 'gravity travels'?
