# Images of infitity?

yeah, that is probably it. I was having difficulty remembering it. thanks.

Excellent point.

A Bosium strip, which is a variation of the lazy 8, well to a certain degree, if not precisely.

Hi, I am new to the forums so please excuse any breach of etiquette.

I am not entirely convinced that 0 or infinity exist except as abstract concepts.

An interesting and troubling development in physics is; that the only way to resolve the various forces in nature into one consistent system may be to remove zero and replace it with a number that is, instead, incredibly small.

The Planck length, about 10^-33 centimeters, very nearly 0 and unobservable is required to make many of the proposed equations work. It may turn out that a zero-point particle such as an electron merely extends a minute length into another dimension.

The physical observible universe is clearly not infinite. It is filled with a finite amount of mass and energy.

A circle is not infinite, it has a definate circumference. It has boundaries and limits.

The historical symbol for infinity is the lemniscate and was designed to resemble the Mobius Strip. Personally, I prefer the Tibetin infinity snake, the ouroboros.

Of course a circle is infinite. From a first person perspective, you try walking around the circle and reaching the end. You simply can’t. Try and pick a direct point as to where the circle begins, again you can’t.

From an ‘‘outside’’ view though, of course the circle is not infinite.

It isn’t infinite from a first person perspective. When you begin walking around it, you start from a particular point and after once around, you arrive back at your starting point.

But it has no boundries. You can go anywhere and everywhere and stll not reach a boundry, you can’t get to a point where you simply cant go any further, isn’t that what infinity is?

You are confusing your trip around the circle, which you imagine can be infinite and the circle itself.

The circle is well defined. It is a series of points that when connected form a figure with a definate radius and a definate circumference. You can define and quantify a circle in many ways. It is bounded.

As for your trip around. If you decide to extend the argument to say that you can walk around it forever, I would beg to differ.

Let us assume that the object making the trip around the circle could do so without stopping. Even though it must have a beginning. In order to continue to traverse the path of the circle would require the expenditure of energy. Were this to hypothetically continue to a hypothetical infinity, the object would absorbe all of the energy in the universe in order to keep going. The univers has a finite amount of mass/energy, therefore the object could not continue to pursue its path infinitely.

Regardless, this ‘‘object’’ still couldnt ever reach an end. Just walk around earth and try and fall off the edge It’s never going to happen. It wouldn’t happen anywhere, but this doesn’t mean that it actually is infinite. The universe does not have to be infinite in order for it to seem infinite to us.

Exactly my point.

Infinity, 0 as well, are both abstract concepts.

They are not real.
They cannot be experienced.

Mobius strip. er thats right. Bosium strip was a card in magic the gathering
