The idea of infinity has always been baffling, can something really go on forever, unlimited and endless. The common symbol for infinity, ∞ was invented by the English mathematician John Wallis in 1657. The most common view of infinity is that it it a number but that is incorrect. Infinity is not a number, but a concept, something without end.
Infinity cannot be measured.
The question is do we live in an infinite universe? Well the answer is that maybe we do, but we can only see a finite section due to the finite speed of light.
Infinity in Numerology
We can show that an infinitely increasing series in mathematics can have a finite boundary.
Take the series where each element is half the preceding element:
Sn = 1 + 1/2 + 1/4 + 1/8 ..... ∞
By simple algebra we can prove this is bounded by 2, ie
S∞ = 2
Hence for any finite value of n
Sn < 2
So from this can we be sure that even if something is forever increasing in size it may be bounded.
