Theology[edit]

I think an article on the Christian theological concept of infinity should be added. As the Catholic Encyclopedia states: "When we say that God is infinite, we mean that He is unlimited in every kind of perfection or that every conceivable perfection belongs to Him in the highest conceivable way. In a different sense we sometimes speak, for instance, of infinite time or space, meaning thereby time of such indefinite duration or space of such indefinite extension that we cannot assign any fixed limit to one or the other. Care should be taken not to confound these two essentially different meanings of the term." — Preceding unsigned comment added by 24.191.87.42 (talk) 00:19, 21 March 2012 (UTC)

  • I'd be happy just to have some brainiac prove that infinity is more than a mathematical concept and has real-world application. In a world of quantum-mechanics, nothing can be measured to infinite degrees of certainty. Religious faith goes beyond what science can prove. I'm just being a realist. — Preceding unsigned comment added by 2600:6C48:7006:200:D84D:5A80:173:901D (talk) 03:38, 17 March 2018 (UTC)

Physics and Infinity[edit]

I could argue that most - if not all - aspects of Infinity in the area of Physical Sciences (Physics) are purely mathematical in basis. Infinity is a mathematical concept intended to represent very large numbers that are (at least thus far) immeasurable and cannot be determined to be finite. Pure physics relies on observations to confirm its theories, and yet all measurements contain experimental error and it is not possible to observe the entirety of infinity. Lack of citation on Physics-based applications of infinity only support my position. I invite others to add to this, or update the article accordingly. I'd prefer to remove reference to Physics from discussion of Infinity, but I think others need to contribute. --68.188.183.91 (talk) 02:30, 20 February 2015 (UTC)

You are making a philosophical argument here; it's not directly relevant to what should appear in the article. No doubt there are reliable sources that have made similar arguments, and those can certainly be cited. However, it is also true, for better or for worse, that the notion of infinity has been and continues to be used in physics, and we are not going to avoid mentioning that just because you don't think physics should use it. --Trovatore (talk) 08:14, 20 February 2015 (UTC)
The article "infinity" should not be purely a mathematical concept. There are great philisophical concepts. Consider death, for sample. You can't measure infinity, or any physical constant to infinite degrees of certainty. Throw in quantum mechanics - there is no certainty. You can't talk about infinity without uncertainty.--2600:6C48:7006:200:D84D:5A80:173:901D (talk) 03:28, 17 March 2018 (UTC)--2600:6C48:7006:200:D84D:5A80:173:901D (talk) 03:28, 17 March 2018 (UTC)

Mistake in diagram in "Cardinality of the continuum" section[edit]

In the "Cardinality of the continuum" section, the diagram displays the first three steps of a fractal to generate a space filling curve.

I think that the first step is wrong: it seems that the horizontal lines shouldn't be right at the top and bottom of the image, otherwise in the next steps the lines would overwrite each other. Instead, the horizontal lines should only be near the top and near the bottom.

Hindi[edit]

In hindi, we call it anant not ananta. And it is the problem that in English, they include "a" at the end. अनंत is the spelling and we read it as anant.

I think "ananta" is appropriate to use in english as per rules of grammer Navjot1200 (talk) 16:19, 24 January 2018 (UTC)

[edit]

I think it is a concept rather than a Number as considered in Mathematics.... Navjot1200 (talk) 16:18, 24 January 2018 (UTC) Navjot1200 (talk) 16:18, 24 January 2018 (UTC)

The very first sentence of the article already calls it a concept. Later in the article, there's some discussion on various number systems that involve infinite quantities. There's also Infinity (philosophy) for less mathematical views on the subject. –Deacon Vorbis (carbon • videos) 16:25, 24 January 2018 (UTC)
