Doesn't 'infinity ' exist only in a maths equation/formula somewhere ?

If one wishes, it was from imagination that such things could be borne.

Infitity to the scientist, means very little else than limits in physics. A limit itself can be indefinate reaching to the farthest sun, and still, infinities run the show all over the place. Theoretically, you could move millions of light years ahead, an still have an infinite path of space and time before yourself.

Equally you could count up all the fluctuations appearing in spacetime. But you would find, only a ghoslty appearance of an infinite amount of energy coming from the vacuum. Where does this energy come from? Why is the energy infinite... what does an infinite energy mean?

Infinity was more or less created by the imagination to account for expansions beyond calculation. Infinity means always that there is one more than now. In equations it works well to describe such natures, but remains itself as a headstone of authority when concerning such abractual idealogies.
