GCSE Physics - Astronomy: How the Universe is made of Galaxies, Solar Systems, Stars and Planets #85

This video covers:
- How the universe is structured
- Planets orbit a central star to form solar systems
- Then solar systems are grouped in galaxies
- And finally the universe contains billions of those galaxies

NO WAY WE ARE THE ONLY ONES IN THIS UNIVERSE, DID YOU SEE HOW MANY GALAXIES THEIR ARE😮😮😮

[@aaronrussell4608]

Any Chance of a video on the expansion of the universe, steady state versus expanding, red shift doppler etc and one on the origin of the universe?

[@georgieeatherington3691]

@Miles Black It is in the spec, they've already got a video out now about the red shift

[@adamabdul733]

Great video to watch .

[@queenneema4650]

Could you guys please make a video about electromagnetic induction🙏🏾thanks

[@Cognitoedu]

Hi Neema, here's a link to that video: czcams.com/video/pkzY7QfTowM/video.html

[@quackquack2436]

Thank you! This helped me understand my astronomy class :)

[@Cognitoedu]

Thanks Sharon, glad it helped!

[@thanansayanbalachandran6081]

your a teacher?

[@catherinvarughese]

Which exam board do you follow?
Is it AQA or Edexcel?

[@spectrum4real208]

the part of physics whihc i enjoy learning aout most...r

[@vedantsridhar8378]

Because you guys watch Sci-fi

My bro is putting Teacher out of commission😄😂 amazing my dude

[@samifeb3094]

Thanks you helped me a lot

[@neowise06]

Lets note that this info is by 2020 only, discoveries can still me made ;)

[@yanmon3769]

this video was soooo insightful, thank you!

[@adamgreen7043]

Btw we do need to know the order of the stars its in the Edexcel specification

[@sheilabirling]

THANK YOU!!!!

[@zachrobinson5534]

When we did this in class people were asking what’s the sun (this is a top set class)
Meanwhile I am sat there looking like Einstein 😂 because I said it’s a star
What am I even doing in school sign me up for a degree

[@amazintechguy3698]

sometimes galaxies can colide and merge aswell

[@user-xw5px4rg9j]

Thanks that's help me a lot !!

[@vedantsridhar8378]

Fun fact: In Freesciencelesson's video on solar system, he actually tried hard not to say Uranus that way.

[@kubahabet6155]

What's an eliptical orbit?

[@Cognitoedu]

It means the orbit has an oval-shaped path, rather than a circular one :)

[@kubahabet6155]

Thank you😊

[@tayooozhao9075]

i think its smth like the milankovitch cycle

[@vedantsridhar8378]

An orbit that's elliptical 😂😂😂

[@eshikagala7329]

Is this for the 2023 syllabus?btw I love your explanations and animations:]

[@HannahThakkar-gk5iz]

Yeah it's in the IGCSE curriculum,so you can probably refer to this for your exams (sorry if I'm too late)😅

[@Dark-vu8zk]

Thanks

[@eshikagala7329]

nice thumbnail

[@zhivkanikolova2033]

Videos are fantastic!! Thank you very much!! But this video is about the Universe and what it is made of, not about the origin and the future of it.

[@epicdorito]

The title of the video is actually: How the Universe is made of Galaxies, Solar Systems, Stars and Planets. So I think the content of the video itself matches its title, because it explains the different parts of the universe, and where they lie.

[@SP-gc1pr]

cant lie i was thinking that too

[@vedantsridhar8378]

Fun fact: In Freesciencelessons' video on the solar system, he really tried hard not to say Uranus. You should check that out and also check out his other videos. He and cognito are my grade savers.

[@hanitosgaming2547]

Sat tel all lol😊

[@prometheus_78]

Im never going to mature and not laugh at uranus.

[@shaykitoff2454]

this is the only interesting physics topic in the entire spec 😂

[@vedantsridhar8378]

All because of Uranus 😂😂😂
