Everyone knows the tapered paper bags you can buy cherries in.
The"Theory of the Isentropic World".
mentions an infinite number of tennis balls that cannot be destroyed unless you are omnipotent, meaning you would be able to destroy them all at once.
Where could you fit so many tennis balls in our world?
You could imagine an infinitely large conical bag, tapered at the bottom, containing the tennis balls.
But if you looked at such a bag from the top, from Earth, the opening would fill the entire sky.
The opening would be infinitely large. Now you have a dilemma.
If my "line of sight"* is flatter than the wall of the bag,
it will never reach the bag. This leads to the conclusion that infinity is just a point,
as seen from Earth.
A mathematical Euclidean model:
In an xy-coordinate system, two half-lines are drawn to the origin in the first quadrant.
If you look at them as x approaches infinity, their distance becomes infinite.
At the finite point, they never meet. However, both lines end at the point x=∞, y=∞.
It turns out that mathematics is not necessarily physics.
