    What is your understanding of 'infinity'?

    In Science, especially in Mathematics, there is mention of infinity. In simple language infinity means something that cannot be limited to a finite number or value. If we say that universe is an infinite place then it simply means that the universe is extending in all directions and there is no end to it. Today we can see the universe upto the distance that our present day telescopes or technology can see. Tomorrow we might be able to see deeper but we do not get an end and that is why many scientists believe that universe is infinite.
    In Mathematics, infinity plays an interesting role. If we divide anything by infinity then we get zero. Another interesting thing is the sum of the decreasing value infinite series tends to a value but never reaches it.
    What is your understanding of infinity? Is it a concept or a reality? Does it have any significance in our practical lives? Please share your views.

    infinity is the conceptual expression of a numberless number. It is often treated as a number that counts or measures things: "an infinite number of terms, but it is not the same number as natural or real numbers. When we add some value to infinity again the value will be infinity only. If we multiply infinity with any number the resultant value will be again infinity only. 3 X infinity will be infinity but it is not 3 infinity.
    This concept of infinity is useful more in physics and mathematics. Infinity may also have an end but our present counting system can't do that. That is why we are calling it infinity. This is a concept by some people.
    Infinity is something that has no end. In general, it has no bounds. It indicates endlessness or having no limits in terms of time, space, or other quantity.

    This term is well understood in Science. It means very big with no boundary. It has no end. If we add infinity to infinity we still get infinity.
    In our mythology the word infinity is used in a spiritual sense and it is mentioned that God is having infinite control in this universe and God Himself is an infinite power itself. So, science has understood it in a materialistic way while ancients had it in the prayers of God.
    Thoughts exchanged is knowledge gained.

    The interesting thing about infinity is that we can never reach it because wherever we reach, infinity would be infinitely further from that point. I got a good example of infinity in a mathematical series. It is a geometrical series and the value of the next number is half of the previous number. The series runs like -
    1 + 1/2 + 1/4 + 1/8 ... and so on.
    Now if we add this for a large number of terms then we would get something like 1.99...... but never 2.
    So in mathematics we define the concept of infinity by saying that sum of these numbers tend to 2 when number of terms becomes infinity. That is called limit of the sum also.
    Knowledge is power.

    Infinity is not a practical number but it is a large number beyond our calculation. It has the characteristics of endlessness. If we divide 1 by 0.0000007, the number will be large enough to be calculated but the same be calculated with a finite number.
    It will be almost difficult to calculate the same if 1 is divided by 10 to the power -100 or even more that, the answer will be large one approaching infinity since it cannot be calculated in the real term.
    In mathematics, we have seen how some sums up to infinite terms containg fractional terms like1, 1/5, 1/25, 1/125 on addition to infinite terms provide us a finite number. It is really an interesting phenomenon.

    If I say 'infinity' at my home today, my wife will search here and there and bring me my mobile phone. Infinity is the brand name of my current mobile phone.

    Joke apart, it was later in my academic classes, say when I was in class 12 that I learned that infinity is not a precisely denotable number or quantity. It just means bend any definite quantification.
    The extent can be very minute even beyond practical imagination or even so large much beyond our normal calculation ability.
    It was then my own logical deduction that 'infinite' is something opposite to' 'finite' or 'definite.
    Infinity means unfathomable, beyond limits, limitless etc. etc.

    It was after learning about Infinity in college that I was able to understand the term in Indian philosophy ,'Anaadhi Anantham" . Ancient India Rishis had found about many things infinite in this vast Universe. That is why they could use the term Viraat Purush- an infinity entity.

    This also proves that concept of Infinity is also known and brought to the world by Bharateeya Rishis, Philosophers and Mathematicians during the Vedic times(though what we generally know is ero was invented by ancient Vedic mathematicians in India)
