The universe is infinite in the sense that it is boundless. Whether it has a size or not, any notion of a larger volume or of enclosing it in a sphere is as abstract as the notion of a continuum.
The number of stars seems finite, but new ones can form, and all of them are so far away that even the nearest ones are seen in a long-past time, years later. The nearest galaxies are visible in such a distant past that our “world history” has not yet begun. Most of the visible stars no longer exist, and most of the existing ones we will never see (this is what I think).
Visible space – a small part of the universe (with a capital letter, the universe with a small letter means a little different) – is boundless in itself, because space is still expanding. And even without taking into account the expansion-the light comes more and more from afar.
Infinity is not understood in practice, but is modeled speculatively. To make sure that the universe is infinite, you need to move endlessly to its edge. But a living person cannot move indefinitely, because his life is finite and very short.
At some point, it will either reach the edge of the universe (if it is finite and small enough), or it will simply give up.
And if he gives up, he will either make an illogical conclusion about the infinity of the universe, or accept his inability to know the practical answer to this question.
A limited resource does not allow a person to distinguish the infinite from a sufficiently large one. For this reason, people confuse great power with omnipotence, great knowledge — with omniscience, and a sufficiently developed and incomprehensible technology is considered magic.

Try to realize this.
Did it work?

But your brain has not realized anything…
