There has to be an end, surely, if there isn't, what is it an us all within/beside/on/under/etc?
As I said, our primate brain uses analogy, metaphor or maths to try and grasp it. But nothing in our human experience equips us to imagine infinity.

It’s the same with deep time. Our universe is over 13 billion years old, but is only at the start of its existence. We can write down the numbers and do the maths, but we can’t really grasp that length of time.

To use the normal (and possibly not as helpful as you’d like) analogy, whee does the surface of the world end? If you roam it on land or on water, where do you get to the bit where it stops?
The surface of the world ends in another dimension. It is still finite when you view it in that extra dimension beyond just the surface. There is still an outside, a beyond.

Science boffins reckon there are more dimensions than the ones we are physically aware of, so whatever is outside our universe is probably in one of those other dimensions that we can't see or even conceive of.

Charity.

By my giving of my money to a needy person or organisation I will feel warm and fuzzy.

Like John Cleese, I don't understand.

Now, I have no problem with that analogy, and the same applies to the surface of the universe, assuming it has one, that I get. What is the universe within? That’s the real mind fk.

The whole universe in this case is the analogy of the surface of the world, but one dimension up.

Just as the 2D surface of the Earth is finite but unbounded so could the 3D volume of the universe be.

In effect this means that with a powerful enough telescope you could zoom in to the far distance and see the back of your own head.
