What is infinity

Post Reply New Topic

Is it process or quantity. Is it an additive phenomenon or is it defined by a process or system which can expand in every dimension infinitely. Is a deity infinite or timeless is there a difference

I'd say infinity is merely an abstract mathematical concept. There are also several different types of infinity in mathematics. As to whether infinity is relevant in the real world, I doubt it.

Spoken like a true meatbrain we cant comprehend infinity but finitude means that you have to posit a first cause for the univerfse. I have no problem with this at all but I dont believe that that's the aim of proponents of the idea that infinity is merely theoretical

Why is "infinity" relevant to the universe's first cause?

Infinity is an approximation. There's a maximum number to pretty much anything (maximum velocity, maximum temperature and so on). At the lowest level ("the theory of everything"), everything in the universe (time, space, energy, etc) might even be discrete.

'Infinity' would seem to be completely an idea in human imagination ...

- computer programs sometimes end up in an "infinite loop" , however, given infinite time, then the computer would malfunction, and the loop would stop.

- the number '8' forms a infinite pattern but without a perpetual motion machine, then nothing can "go forever" on such an infinite pattern

- 'infinity' is a very important concept in probability theory , probability laws conceptualize that "given an event X happening an infinite number of times then we expect a particular probabilistic outcome" , however, events at the macro-level cannot happen an infinite number times i.e, a human cannot flip a coin an infinite number of times, so this appears to be entirely conceptual

- 'infinity' also comes up in mathematics will regards to integrating over physical space, however, there is no evidence that space can be infinite

- 'infinity' is used at the QM level based probabilistic expectancy or "infinite worlds", etc. however, there is no evidence that QM world works based on infinite probabilities or infinite worlds exist

- irrational numbers would seem to never end i.e., have an infinite number of repeating decimal numbers e.g., see my picture on left side of SQRT (2) is the finite space for the hypotenuse and never ends. However, math is made-up by humans.

There are conclusions that you can't reach without data. Cosmologists can set up models, some of which are infinite forwards and/or backwards, but without more data they can't know which sorts of models are appropriate. The answer, whatever it might be, will violate the intuitive common sense of every day life on Earth.

I personally wonder whether the universe will continúe to expand indefinitely, and whether time will keep going on and on and on forever

It is the suspicion that one's amplifier could always be one louder.

Turtles all the way down.

Infinity is like this: We know the universe started 13.8 billion years ago, and we know the heat death of the universe might be in 100 trillion years. Ridiculously large numbers to be sure, but even they are small.

There is a Video on youtube called "Ten dimensions explained" that is pretty awesome.
