The Universe is very, very big.It also loves a paradox. For example, it has some extremely strict rules. Rule number one: Nothing lasts forever.Not you or your family or your house or your planet or the sun. It is an absolute rule. Therefore when someone…

I've always liked discussions on the nature of infinity, in any context: mathematical settings, such as the infinite intersection ⋂_(from 1 to ∞) (-1/n, 1/n) = {0}; in a philosophical setting (knower knowing the one who knows, etc.); and of course the setting in your post, addressing the universe. Thanks Corina, a nice quote and the image is a delight as always.
ReplyDelete"Rule number one: Nothing lasts forever." => Infinity does not exist.
ReplyDeleteI had come to that conclusion as a 12 year-old... Namely, that "non-repetitive infinities must not exist", because assuming something to be "maximally infinite", necessarily implies repetition. For example, arbitrary given sequence of digits of number π can be found somewhere far away in the π itself... or so I thought back then. Actually, we don't yet know, if this is the case, and if π is a normal not normal. ( en.wikipedia.org - Normal number - Wikipedia ).
"Rule number two: Everything lasts forever." => Repetitive infinities do exist...
"infinity" by repetition is rather inductive. Infinity per se is non-existent. In other words, neverending is not (and does not imply) infinity.
ReplyDeleteRepetitive "infinities" do not exist per se; repetition exists, and claims of ability to run algorithm forever exist, but neither implies infinity per se.
ReplyDeleteMindey I. there is no issue with lexical ambiguity at a glance - but is this something we should be more considerate of?
ReplyDeleteRe size of Universe, how can I ascribe a size if I cannot discern an outward boundary? Size is a relative concept, Universe is related to what?
ReplyDeleteCorina Marinescu I was looking through your posts, hoping to see where you might be found online once G+ is dead and gone, but I didn't see anything. While I haven't been active on G+ in some time, you were always one of my favorite people to follow, because you share so much wonderful and varied information.
ReplyDeleteDo you have a website or other social platforms, where we can follow you?
Charles Payet: she crossposts from myfusimotors.com, the website she runs.
ReplyDeleteCharles Payet for now I post on wordpress but after G+ gets invisible I'll post also on Pluspora.
ReplyDeleteNot sure how it works, I've made an acct but I so hate it to move from a platform to another.
I'm old school...however I'll keep wordpress as a backup because looks like these platforms tend to have an expiration date.
Wow Amazing.
ReplyDeleteCorina Marinescu what's your Wordpress site?
ReplyDeleteIf infinity exists, show me.
ReplyDeleteMichael D Kendall I appreciate the sentiment, but not the argument; for example, a good idea is not really showable but may be demonstrably valid by reference. Infinity per se, however, cannot even be reliably defined, is not even a tenable idea. So, if by "show me" you mean something akin to "describe to me, without using circular reasoning, how the notion intended by the term infinity relates to my experience" then ok.

ReplyDeleteCorina Marinescu well, maybe you could make a business account (google.com/a) on Google? (cause they will leave those in-tact, and planning new features for G+!). I suppose they wouldn't do such a reckless things with businesses.
ReplyDeleteAnd all truths are but half truths
ReplyDeleteCorina Marinescu terrific, thank you!
