Physics: What Is The Universe Expanding Into?.

**Discussing the existence of, and ideas surrounding, the multiverse.**

This is an abstract idea, but remember: it is just theory – an idea.

It’s probably important to express that I am a believer in the existence of a multiverse, which is comprised of an infinite number of every possible universe that could exist. An essential point to take into account is that, since it is everything, the universe occupies no ‘space’. It is a zero-dimensional point, within which the spacial dimensions we exist in are contained. So it has no size and occupies no space – space is contained within it. Anyway…

**The universe has neither beginning nor end – a zero and ten-dimensional, infinitely cycling existence.**

Apologies in advance if I begin to waffle – transcribing my thoughts into a post has proved incredibly difficult. To start, reading my posts *Sims: What is ‘time’ – exploring the fourth dimension *and *Sims: Free will doesn’t exist – the universe is ‘scripted’* will prove extremely helpful in understanding this idea, so I plead you to do so before continuing.

Anyway, this is an original idea of mine, and is something that wreaks absolute havoc on my mind. I really hope you will enjoy it. You must completely disregard the idea of time in order to visualise this; because our minds are so fixated on the universe unfolding via ‘time’, it will be very difficult to achieve this visualisation without doing so. Remember: TIME DOES NOT EXIST.

# Marais: Pi = Infinity(?)

Pi. π. 3.14159. A mathematical constant; an infinite number – the ratio of a circle’s circumference to its diameter. Records of its use date back to Babylon and Egypt, as early as 1900 BCE, and both civilizations developed approximations within 1% of pi’s true value, and the number has proved infinitely important to both maths and science – whilst it’s use can be as simple as helping to calculate the diameter of a circle in a maths class, or for laying foundations to a circular building, we have been able to use the number for far greater purposes: in calculating the circumference of the earth, for example.

The most interesting thing about pi, however, is its irrational nature: it can never be expressed as a ratio of two integers – thus, it’s decimal representation never ends, and it can never settle into a permanent repeating pattern. As of late 2011, scientists have extended pi’s decimal representation to THIRTEEN TRILLION digits. That amount alone is incomprehensible to all but the most skilled mathematicians – I can’t begin to comprehend its enormity.
