Hi,

The only 'endless' road would be a circular track along which you could travel without limit and still not reach an end

How do you know this for sure a circular road is more closely linked to eternity.

Infinity is an expression of potential not absolute,, the void of the universe might be infinite. When the universe expanded out from the creation event, space, matter, energy and time came into being. Now space has no mass and is , therefore not inhibited by the light speed constant, so it might have expanded out into the vastness of infinity.

Of course you cant use infinity as a multiplier it can only be used as a consept like zero.

Most of mathematics that deals with the infinite can be interpreted as dealing with the potentially infinite. For example the question of whether a species will have an infinite chain of descendant species can be defined in a way that requires quantification over the reals.

There is no single event that decides this question but it is still meaningful and interesting in a potentially infinite universe. It is determined by a recursively enumerable set of events that can be listed by a computer. Some questions such as the Continuum Hypothesis.

An intriguing question is whether infinity exists in our physical universe: Are there an infinite number of stars? Does the universe have infinite volume? Does space "go on forever"? This is an important open question of cosmology. The question of being infinite is logically separate from the question of having boundaries.

The two-dimensional surface of the Earth, for example, is finite, yet has no edge. By travelling in a straight line one will eventually return to the exact spot one started from. The universe, at least in principle, might have a similar topology; if one travelled in a straight line through the universe perhaps one would eventually revisit one's starting point.

If, however, the universe is ever expanding, and one's means of transport could not travel faster than this rate of expansion, then conceivably one would never return to one's starting point, even on an infinite time scale, since the starting point would be receding away even as one travels toward it.[

I admit that Infinity is a very tricky concept to work with.
