@evanthorizon: Measuring the rotation curves of galaxies revealed one of the biggest mysteries in physics: dark matter! If understanding physics and math feels like a mystery to you, @Preply tutors are here to help! Use code EVAN50 for 50% off your first lesson! #ad

Insanebugbear...Chris :

Do you think "dark matter" is a thing or is it just math we don't understand yet?

tabbysmooncat :

And people think this is all fake

Goofy goober :

Only 500kms?

INSIGHT :

My algorithm senses your new videos with the accuracy of a blood hound [Fire]

Dustin White1591 :

So is dark matter just the name of some force or forces that we don’t understand?

thatdan :

I’ve heard scientists talk about rouge planets that don’t have a gravitational body to circle but are there star systems that don’t have a galaxy/black hole to circle? They just float out there in between galaxies

potato :

watching this in school and this is more interesting

so.over.vic :

Unfortunately the galaxy with 5x the rotation speed of the Milky Way has an axis pointing right at us :(

TBNRbelciña :

I cannot just fathom how us just a species of a small planet can discover let alone know these things

fish.yeeks :

Holy shit that so cool!

jodiebean 🇮🇪 :

I think about spectroscopy an abnormal amount.

tfftoolshed1 :

Arent the stars closest to the black hole in the middle spinning a lot faster than the ones on the outside? 😅 How the fuck do you decide the speed of the whole galaxy

❤️♥️Ivan💙🩵 :

Eidan :

so cool, is based on the Doppler effect the light analysis

EV6N :

my fyp knows you personally 🔥🔥

Meow :

speed in the universe of so many bodies is just so insane to think of. not to mention the way we measure speed is crazy cool and smart

Mijo :

Peak

Renzo :

Mahir :

Nadir.H :

dose he have youtobe Chanel

pewpewthismf :

Damn

Jon :

"TWKO"(þat we know of) should become a Suffix in þe Science Community.

High Kage :

dark matter acts as a lattice holding the galaxies together.
