How big is a human compared to our galaxy?

ok, just watched that
kinda fun
but this stuff always raises more questions than it answers
questions like
I wonder what an electron thinks of all this?
now don't be absurd and try to say electrons don't have minds
you have one and look how small you are!
anyway your tiny mind couldn't possible prove or disprove an electron can have thought or mind
but more importantly why should anyone care?
the universe is but a grain of sand in the butt crack of someone with a much larger mind..
hold on a sec while I scratch this backside itc.............................................................................................

The ultimate challenge to science-fiction writers is to write something interesting about interstellar space. That's why 99.99+% of "space" science fiction features faster-than-light travel of one type or another. Nobody cares how big something is, only how long it takes to get from interesting point to interesting point. The "interesting points" of space fiction being on or near mudballs where stuff happens.
You're right. Ants are about 1.3 to 15 mm long, the Milky Way according to NASA is about 100,000 light years across, and the observable universe is about 28 billion light years across. So the observable universe is about 280,000 milky ways wide, and the milky way, taking 10 mm as an average size for an ant, is about 100 billion trillion ants wide. One can also argue that the observable universe is about 93 billion light years across, because in the time since the Big Bang the things we can see at 14 billion light years are now that much further away due to the expansion. How much bigger than that it might be we can't tell, no light has reached us from that far away, and never will. Even so, you're still right, unless I screwed up the arithmetic somewhere.
I think humans have trouble understanding how big the Universe is. We even have trouble getting our heads around how big even just our galaxy is - it'll take 100,000 years to travel across even at light speed - and it is just one of trillions of galaxies in the Observable Universe.
The Observable Universe is 93 billion light years across, but the entire Universe could be millions or quadrillions of times bigger.
maybe, since we're talking unfathomable numbers, only to be dwarfed by the unfathomable volume of space in the cosmos... perhaps the smallest unit of volume could be, say, a cubic light year. Now consider a googolplex of cubic light years, to the power of, or with the exponent of one googolplex... that is, a googolplex to the power of a googolplex of cubic light years, and yet that may only represent a mere grain of ice at the tip of the iceberg.
is there really any point in wasting our tiny minds contemplating it all?
don't worry, be happy
Kasner also coined the term googolplex. And how many zeros in a googolplex? A googolplex is a 1 followed by a googol of zeros. It's impossible to write out, but in scientific notation it looks like 1 x 10^10^100.

same name then?
I didn't study it.... just wanted to put the definition of 'googolplex' down
