wait

really?
'

and not bent like a rubber sheet

flat in 3 dimensions ofcourse

Euclidian

Like fr?

i didn't think that analogy worked

but oh well

the circumference of a circle is always C = 2 pi R

yeah, tis flat

Wait you said flat in 3 dimensions

we're flat spacers

I guess so

Wait

If space flat

If space is positively curved, then C < 2 pi R

Why am I not flat

the existence of dark energy gives an even higher likeliness of it being flat

if space is negatively curved, then C > 2 pi R

that really warps my mind

Ok but when you say space flat

Do you really mean as flat as paper

how flat the universe had to be when it was small in order for it to still be flat now

so I'm talking geometry

Sort of

and with that, black holes are not "holes"

How

they're just called that way because they eat up all the light that comes their way

They are “wells”

they look like a 'black hole'

in space

if you line up R number of meter sticks from the center of a black hole to its event horizon, and then measure the circumference of the event horizon you still end up with C = 2 pi R

But they holes tho

If space is flat than its infinite. If it’s curved, then it’s probably a closed system

whoa

Yoooo

why *are* black holes round?

Becuase
