In the usa, italians are their own thing in the ethnic diaspora, and generally not thought of as latins, which is pretty funny.

I keep saying quebecois are latinos and people keep trying to silence me

Glass permits light, yet it's solid!
*places a cup on a horizontal plane of glass*
How are we okay with this??

"Oh but you can still see glass it's not actually invisible"
Okay smart person!  Dive into this swimming pool!
I'll tell you right now- it's full of panes of glass.
Why do you hesitate?  You see nothing amiss!  It looks like ordinary water!

It's fine for light to clip through solid things because light is Weird and does Weird things all the time. Such as travel at exactly the universal speed limit, like what the FUCK

Isn't it nuts how there is even an upper limit to speed. Who wrote these rules anyways

Just the constraints of the simulation to prevent any glitches or slowdowns.

Same for absolute zero and absolute hot.

Nah being entraped in time we couldnt notice changes to it's speed, like in DF the drawves can't know your fps, in their subjective world it is the next tick that counts... So it's more like the resolution of reality.

The weirder thing is how solids stop light usually, a thing which for years people thought traveled through an ether. Especially the fact that ordered crystal structures will scramble light, but randomly arranged haphazard amorphous structures let light travel straight through.

The irregularities in glass are on such a tiny level that they average out.

Ah, but the simulation-makers would witness the slowdown.

It stays crunchy, even in milk.

Light slows down to about 75% its max speed when travelling through water.  That's quite a significant decrease.  I wonder to what extent space dust / interstellar gasses slow down light as well?  I tried to find data about that, but instead ended up down a rabbit-hole about interstellar ramjets: using magnetic fields to funnel hydrogen from the interstellar medium into a fusion reactor.

this puts the upper limit on the index of refraction of space at 1+10^-13.

Basically the slowdown is nonzero, but it's very small.

(For reference, water's index of refraction is about 1.3 as you said; diamond is very high, at 2.4)

I hate Rafadan Tayfa. Not in a "this sucks and it is awful" kinda way.

You know that feeling when you look at something really cute and want to kill it violently? That is my hatred for this stupid fucking kids show. The characters are annoyingly good at endearing themselves to the viewer, and their faces are so baby-like.

I love it. I want to tear it apart.

The most extreme I found was germanium at 4.0 - 4.1 which interestingly, is used in fiber optic cables.
