This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground
The mind truly boggles when you try to rationalise all this.
The idea that, barring some substantial developments in our understanding of physics, we can never reach any of those entities is pretty salutary.The mind truly boggles when you try to rationalise all this.

Astronomy is one those fields where the more you know, the more you realise how little you do know.
There’s between 100 billion and 400 billion stars in our galaxy alone.
Using the sand analogy, how much sand is that in buckets?There’s between 100 billion and 400 billion stars in our galaxy alone.
ETA Quora says using average grain size, 43 million in one bucket
So for 300 billion stars I make that 7000 odd buckets if my calculation is correct.

I made the calculation using « average » size above, I think!s7000 buckets!

There's about 100B neurons in the human brain, [each with 15K connections], so about as many stars [lower limit] as in the galaxy. It's like the galaxy shrunk into your head. There’s between 100 billion and 400 billion stars in our galaxy alone.
Hows about them onions eh?

I can't even begin to get my head around the scale of this. It bothers me how incomprehensible it is.
