Does infinity exist in science?

Although the concept of infinity has a mathematical basis, we have yet to perform an experiment that yields an infinite result. Even in maths, the idea that something could have no limit is paradoxical. For example, there is no largest counting number nor is there a biggest odd or even number.

What is an example of infinity?

Another good example of infinity is the number π or pi. Mathematicians use a symbol for pi because it's impossible to write the number down. Pi consists of an infinite number of digits. It's often rounded to 3.14 or even 3.14159, yet no matter how many digits you write, it's impossible to get to the end.

What is the study of infinity?

Infinity is that which is boundless or endless, or something that is larger than any real or natural number. ... At the end of the 19th century, Georg Cantor enlarged the mathematical study of infinity by studying infinite sets and infinite numbers, showing that they can be of various sizes.

What is infinity used for?

Infinity is often used in describing the cardinality of a set or other object (such as a list or sequence of terms) that does not have a finite number of elements.
