    Infinity
In summary, some mathematicians and physicists believe that the universe is actually infinite, while others believe that it is simply a concept that is difficult to grasp.

I think you guys are stepping off the precipice of rational thought into the mystical "woo woo" chasm.

..the fascinating and unavoidable constant Pi. This guy is just amazing… one end rooted in its finite integer while the other is still for us to reach, on its way to Infinity.
I suppose you could say that about all irrational numbers. I'm very fond of the square root of two!

So, if at all we are part of the consciousness (which I believe) then we must get back to the source.The same source, which the thiest calls god, the philosopher calls the goal,the scientist calls the universal power and the budhist calls nirvana and the christian calls the eternal kingdom, the hindu calls moksha. The same law which holds good in our worldly life also holds good in our religious life and in the life of the cosmos. It is one, it is universal. It is not that religion is guided by one law and the world by another. The flesh and the devil are but degrees of difference from that source itself.

I would say, to know that infinite is to become one with it. To be more precise, to realize that we are already that infnite.

Become "one with infinity"? Physics Forums is primarily a science and math education/discussion forum. The loosy-goosey spiritual/metaphysical conjecturing won't get much truck here. There are plenty of places to have fun with these ideas on the internet, but this is not one of them.

1. What is finitism and how does it relate to infinity?

Finitism is a philosophical and mathematical approach that rejects the existence of actual infinite quantities and instead focuses on the use of finite quantities in mathematical and scientific theories. It argues that infinite quantities cannot be physically realized and therefore should not be used in scientific explanations.

2. How does finitism impact our understanding of the universe?

Finitism challenges the idea of an infinite and eternal universe, proposing that it is instead finite and has a beginning. This has significant implications for our understanding of the universe and its origins, as well as the laws and principles that govern it.

3. Can we apply finitism to all areas of science and mathematics?

Finitism can be applied to most areas of science and mathematics, but it is most commonly used in the fields of physics and cosmology. It is particularly useful in addressing paradoxes and limitations of infinite theories, such as Zeno's paradox and the concept of infinity in calculus.

4. How does finitism differ from other theories about infinity?

Finitism differs from other theories, such as mathematical Platonism, which argues that mathematical objects, including infinite ones, have an independent existence.

Finitism, on the other hand, argues that mathematical objects are created by the mind but must also have a physical counterpart to be considered valid.

5. What are some potential implications of adopting a finitist perspective?

Adopting a finitist perspective can have significant implications for our understanding of the physical world and the laws that govern it. It may also lead to the development of new mathematical and scientific theories that better align with a finite universe. Additionally, it may challenge long-held beliefs and theories, leading to further exploration and understanding of the universe.
