Our comedy needs oxygen, it can’t survive in a vacuum.

So how much space does one of these cleaners need?

Well the universe is approximately 93 billion light years across, so how much can you give me? :smiley:

Splitting hairs that’s the observable universe, the actual universe is larger, possibly MUCH larger.

We are twelve billion light years from the edge

You too?

And you will of course note that I used the word “approximately”, O Grand Hair-Splitter. :smiley:

Well, yes - but it is thought the whole universe could be 20x (or more, pick an arbitrary number really) what we can see which stretches your “approximately” quite a lot.

“edge”?

The observable universe is a sphere of roughly 46billion light years. If you are sitting there thinking, “hang on, the universe is only 14 billion years old - how can anything be further than 14 billion light years away?” the answer is that expansion of the universe has been happening at the same time.

The universe allows a LOT of space for drift. :slight_smile:

You’d need a bit more than a robot vac or even ‘seven maids with seven mops’ to keep that clean (‘clear’ for pedants)

You are not suggesting a flat universe theory?
