The one about the set of sets that doesn't contain itself?

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.

Because surely it must live within something, I am thinking of the marbles scene at the end of the original Men in Black, But, then what is at the end of that?

There has to be an end, surely, if there isn't, what is it an us all within/beside/on/under/etc?

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?

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.
