This always breaks my brain, and I'm interested to know whether any of you get the same thing...

Ever since I was a kid and became aware of infinity and the scale of the Universe, attempting to imagine it would go well for a couple of seconds, then I'd get a sensation not unlike falling off a log as my brain hit the whoa-fuck! wall — as if it had just blinked out for a fraction of a second; a sort of startle response... 'noo-ope, don't go there'.

The same thing happens when I think of the 'why is there something rather than nothing?' question and also when I try to get my head around what might have originated the Universe.

There's a brief panic and a pulling back from the brink, and I don't understand why. I can cope perfectly well with not knowing all manner of things, so why do I have some ingrained anxiety about things that are outside of my perception?

What about you? Do you get a spinning head or is it just a 'meh — don't know' for you?
