Think of infinity as a 'never ending distance/object'. If you can imagine the number of grains of sand on earth, it is not approaching infinite. The earth has a finite volume and a grain of sand has a minimum volume. If you divide the volume of the earth by the volume of a grain of sand, you still have a 'real number'. It is not infinite.
About 30 years ago, we were shopping at the Pickering Town Center looking for a new stove. The salesman jumped right in to help, and explained that the stove had an infinite temperature range. I told him that if we were to live forever, we would never appreciate that feature. He had no clue about what we were talking about.
For cameras, to get back on topic, many camera lenses have a couple of index marks indicating the range of focus for different f-stops. I usually set the upper index mark on the 'infinity' mark so that, for example, for an f-16 aperture, it may be everything from infinity to say 30' is in focus rather than set the focus distance at infinity so that only 60' to infinity is in focus.

When all the stars and planets are destroyed and not even a speck of dust is left, what you got is infinity, the only thing infinite is space, nothing else.

Just because you don't know how space ends, doesn't mean it's infinite.

To see the world in a grain of sand,
And heven in a wild flower.
To hold infinity in the palm of your hand,
And eternity in an hour.
Explains everything.
And heven in a wild flower.
To hold infinity in the palm of your hand,
And eternity in an hour.
Explains everything.

What I love is most lenses can focus past infinity... The future? Another earth? Another galaxy?

You are either too young, or way too old if you don't know who Buzz is.

My eyesight is failing, so there's little to be gained from squinting beyond infinity... maybe best to set that as the 'farthest limit'.

I recall a poem from decades back about a man searching for beauty in a field of daffodils... and a line about 'man the enigma'.

I would ask Buzz Lightyear but I don't see him around at the moment. Of course he thinks there is, To infinity and beyond. How far is beyond though? Good question.

According to my 6 year old grandson the only thing greater than infinity is infinity plus 1...or 2....etc. We went on with this discussion until he got bored with it😊

Once you add a qualification to a word like "infinity" it no longer IS infinite ....
Isn't that right, Dann?
Try and explain THAT concept to a 6-year-old .....
