Or is there a limit? Please share your views with us. Thanks!

There are more of you??You may have to consider calling yourself "WE SCIENTISTS"Can you or your committee rephrase your question in order to make it a little clearer?I am not certain as to what the real nature of your question isThanks for your help

Hi allI believe I understand what The Scientist is trying to say. 2 mirrors which are parallel to each other, will give you and image formed that is replicas of the two mirrors, so you'll see many identical mirrors. Hope it helps!MGM

If the mirrors are perfect i would say yes, but since mirrors are never perfect you will not get an infinite amount of reflections.

will 'it' still represent a infinity to us?

light cannot be projected off a mirror into infinity - eventually the mirror absorbs the photon energy.

And where you can't find a limit I would say you have a good contender for 'infinity'

[]You might have a good contender for a mathematical infinity; in reality, unbounded might be OK, but infinity is a different thing altogether.

In theory, yes. In practice, you'll eventually have so little light that you can't hope to measure it any more.

true - but it can never be equal to ZERO (exactly)

In practice, all you're really doing here is using the bounces to time the age of the universe, so if the universe's age isn't infinite, this won't form infinite images.

The corollary of this is that if the Universe's age is not infinite, which seems to be the case, it can never become infinite, even though it may be boundless.

You can certainly form an infinite set of things from discrete elements. For example, there are infinitely many natural numbers (i.e. 1,2,3,4,5,...), but these are clearly discrete elements.
