That appears to be a meaningless observation, both mathematically (nothing can be multiplied by "infinity") and physically.
Is there a math symbol for 'Now' used in math like or unlike Calculus? Is this worthy of consideration in discussions of time and distance?
There is no such symbol, because the concept of "now" isn't useful. Time is almost always treated as a value that defines an interval. An expression may be evaluated from t(0) to t(1). Or a single value, like t(n) might be used. The point is, "now" is just another time, with no particular significance. If you were describing something with respect to "now", it would be most common to simply set t=0.

A physically real 'now' might help explain non-locality, as would a particular event in a particular place multiplied by infinity and able to appear anywhere .. again, such as in non-locality. Your t=0 strikes me as no time, so no 'now'. I prefer Astro's >t<
It seems to be that since scientists once believed heavier than air flight and moon landings impossible, that if we could get that kind of barrier to thought removed from non-locality, we might find explanations for it, and applications for it .. like instantaneous travel to a place billions of light years distant, even if that travel meant the 'clone' of the traveller doing the travelling, but the original traveller, seated in aparatus, seeing and hearing as if he was the clone. Of course, this must have been explored in Science Fiction, which I stopped reading three decades ago, but I see the possibility of success as real as those examples mentioned: heavier than air flight and moon landings, which were also the subject of Science Fiction. As far as multiplying with infinity goes, who could have imagined Calculus before it was discovered (or formulated) .. not that I know Calculus, merely knowing of it, with this lack of knowledge, like Faraday's, compelling me to discover other paths of exploration and description.

My understanding of the word universe, according to definitions, is all the physcical matter that exists anywhere .. so, as I believe groups of galaxies are generally increasing in their distance from each other, except those groups drawing closer to each o5her, that the universe is expanding. However, this means if the universe is not expanding, that compression may be going on at the farthest 'edges'. Such compression could be the trigger for the ultimate explosion of the universe, of which my reading says that explosion will happen.

Yes, and Makc and I are in pleasant and private discussion about it also .. and I have some enlightenment, but disagree with you Jim that what is not observed does not belong in Physics, as Dark Matter and Dark Energy are not seen, yet must be considered (either neutrally, positively or negatively).
My sticking point in the Wiki quote is
"Action at a distance is incompatible with relativity."
I hope to reconcile this with the rest of the article, as it seems a contradiction with the rest of the article.

Not at all. Since time specifies intervals (an isolated point of time is meaningless), and since time flows at a constant rate (the interval between t=0 and t=1 is exactly the same as the interval between t=5 and t=6), the choice of reference value is arbitrary. It is usually most convenient (the calculations are simplified) if the reference value is zero. So if you are performing some calculations with respect to "now", you would probably want to set "now" equivalent to t=0, with signed time values on either side of that. Of course, you could use any value you wanted and it would have no impact on the result of the calculations.

I truly appreciate your comments; but I disagree that an isolated point of time is meaningless .. if it were, non-locality, it seems to me, would be impossible, as the effects occur at the same time. I also disagree that time flows at a constant rate. If Chronons are real, for instance, they could clump, meaning time would run faster in clumps, and slower in individual Chronons .. or, perhaps, reversed, clumps might impede the flow of time. I hope the last comment reveals that I don't think I know it all, but rather enjoy exploration.

taking the risk of driving you even more crazy, I would like to point out that relativity makes "now" defined differently for different observers, e.g. things that happen at the same time for you, happen one after another for everybody else, and half of observes sees them happening in other order than another half (btw, exactly because you see them happening at the same time; otherwise, these events could be strictly ordered... because, you know, relativity cannot undermine causality).

apart from basing your disagreement on "if" assumption, how on earth would you notice that your time rate has changed? there is a clock to measure time, but there is no device to measure time speed or acceleration (in other way than by comparing 2+ different clocks).

Remember the clock and the round about. The clock on the inside ticks slower. Gravity does affect time, as they are entangled in the frame work the main guy set out. Question should be, does a black hole affect time on the outside? just like the BB singularity did? I would like to know the difference in time from Event Horizon to the depths of a black hole. Could Time in the center of a black hole be at a stand still, .5 of a second after the Big Bang? If we can look back, in time, that far via photons why can this not be true also? These are my views, what you have just read. just for the purpose of understanding the unimaginable ..

Einstein's development of GR is what showed the Universe expanding (there is no issue of energy being created, so no concern there). Einstein, like many other early 20th century physicists, found the idea of an expanding universe philosophically distasteful. So he invented a fudge factor, the cosmological constant, specifically to force his theory to allow for a static universe. A few years later, he was convinced by the work of Hubble that the Universe is indeed expanding, which is when he removed the cosmological constant and famously referred to it as "his greatest blunder". I would think that tracking down the exact details of that quote would answer your question with respect to Einstein.
I have no idea what Feynman believed deep inside, but I know from first hand experience- being in his classroom and in seminars- that he was very comfortable talking about relativity and expanding space. I remember one talk where he was drawing world lines in an expanding space. I never heard anything at all to make me think he didn't completely accept that the Universe is expanding.
I doubt that either man believed in energy being created. Your suggestion that an expanding universe somehow requires that doesn't seem to be shared by other physicists.

As you are aware, I ride slowly on substantial wheels and tires, so the risk of being driven crazy is more easily avoided than if flying on rollerblades, for instance, although, all things being relative, my riding is flying compared to canoeing, so the risk is relative, especially when contemplating some of my relatives, and they contemplating me .. and the walls which seem to insulate minds from thought.

But, isn't that what relativity is missing? Just because different observers observe at their now does not negate the now of the occurence .. that now, multiplied by infinity, giving (not eternal now but rather after having pondered things more fully) infinite now, which non-locality taps into, infinite being a measure of space rather than time, and affording, I repeat, the luxury of non-locality.

Big Bang is based on the IF assumption of the cosmic egg or singularity, yet BB enjoys tremendous support from some of those people on this forum. I am not concerned in the least about measuring my personal time rate, only in interesting investors in the opportunity of showering me with millions of dollars with which I can develop my non-loco-powered apparatus with which we can tap into non-locality and with which to travel virtually to distant places in the universe. This is a sure investment, with guaranteed returns, please send big barrels of cash to: Mxylplyxl Development Company, Peterborough, Ontario, Canada. (And they said I was crazy!)

But we both know ,, There is a clock on the inside. Two clocks running at different speed has been proven. The fact we can not see, the inside clock Tells a story.

Now only has meaning with respect to the observer, not the event.

BBT does not require a singularity. That there was a singularity is only an assumption (and not a universal one even in BBT) that arises from the observance of an expanding universe. Very little can be known about the universe prior to
CMB. Any ideas about the very early universe are speculative and belong to the realm of
cosmonogy not
cosmology.
