@cleoabram: These are some of the smoothest, most reflective mirrors in the world! They’re polished to have bumps just a few atoms thick! They reflect 99.9999% of the light that hits them, but they’re not FOR visible light! They’re made to reflect light from an INFRARED LASER that’s part of the most precise experiment humans have ever built. To see what it’s for, follow along! #Science #LIGO #light #laser #Tech

zenvyra :

So you always end your videos with like “if you want to see X, follow along,” but do you ever actually post a follow up video showing us what X does?

At what point does all the 9s in front of 99.99999% turn into 100%??

Robs :

Mirror i thought it was glass 😭😭✌️✌️

just say it's 100% instead of saying 9.99999999%😭😭😭

Charles Smith :

POLISHED?!

Dion :

why not 100%?

Empitrix :

used in ASML?

raice :

can't say I ever considered the smoothness of my fridge tbh

this mirror Vs vanta black

fr. :

you look like haley baylee

Martian :

You never do the part two you promise!!

SmylesEntertainment :

I LOVE THIS PAAAAAAGE

TheTreePenguin :

how do mirrors work? is it just that they are smooth so the light bounces back in an orderly fashion?

Ethan :

first

PS5 controler :

why not 100% ???

Ricardo :

cool 🤙

cortizo 11 :

who funds the science projects

EclipsedByJ :

yoo

🪐 :

So you can't explain what it does in this video?

Law Michael. :

So it’s not a mirror? 🪞

Brian Myers :

I'm pretty sure EUV mirrors are even smoother
