@popculturescientist: How do you like your light? Old, like really really old!! The cosmic microwave background is our last piece of evidence that something is off with gravity. But what can it tell us? This us is Dark Matter Explained: episode 7. The Cosmic Microwave Background #physics #stem #popculturescientist #cosmology #Astronomy

Ur in stem btw

PeterInFlorida :

I was a mond guy, but now I’m primordial black holes.

Sebastian :

If any aliens are watching heres earth

Mfundo Sithole :

lol love how it is no longer a definite thing to say the big bang, at least as it is understood, was the beginning of this universe.

steve adams :

my lights only last a few months

Tarnwyn :

Will there come a point when the CMB will have red shifted to the point that we can no longer detect it?

TarshaBlow :

High

Leitmo :

I like how TikTok shows me this series every evening. It’s like a ritual.

Ad🔺mn ☭ :

So the universe was once opaque?

Vicar of Dimbleby 🇪🇺 :

The part that I do not understand is how can we see that light when the universe formed (big bang)? If our planet formed after the big bang from dust projected by thr bing bang and went to occupy its place in space as early as one year after the big bang then the light from the big bang will have passed through that point in space earlier than our planet formed. Unless the dust expansion and planet forming was faster than the speed of light which is impossible.

Telemark :

Sometimes you think you have a slight grasp on the subject and then my head starts to hurt.

innerwildxp :

I was wondering how I got to stem TikTok but I am interested 😂

jpbebbington :

Mass that you know must be there but can't sctually find... That's sounds like my socks. They're always going missing.

SrotoGargees :

... but how do you picture it when you hear this in the radio frequency after microwave.. it just just hisses.. is that what actually was happening b4 .. particles going here & there

Tweep :

obviously it's giant space frogs. there's no other possible explanation. 😁

Kingsizecrunchie 🇬🇧🇳🇿🇬🇾 :

There was a sentence there, that I am excited to spend a a week understanding.

Waterharvester🇦🇺 :

Surely that graphic of a galaxy spinning is not a correct representation. Do galaxy’s have more and more spin as you get closer to the center like a whirlpool? Or does the whole galaxy spin more or less as one entity?

فلَك :

Omg i lovvve the way u explain it 😭💖💖

Chachaslide12345 :

Explain pressure from light.

945 :

Ok. Can you explain your phase “pressure from light”. I seem to not understand how light can cause pressure. Thx

Dr_PCR..Ph.D :

My microwave is in the background of my kitchen & I make meals that are cosmic. Does this count as cosmic microwave background radiation?? 🤪🤪🤪 🤣🤣🤣 😎.

. :

So cool ✌🏻☮️

x_croodle_x :

omg I just realized I was in stem

ðe last sunsets :

is this mutually exclusive with that idea that you can extrapolate interference patterns from ostensibly ancient gravitational waves in the CMB?
