every point in the universe can be assumed to be the centre as the universe is expanding everywhere at the same time. so what ever point you pick in the universe, everything looks to be moving away from that specific point.

"They must be booking it away from us" got a laugh outta me. Great explanation!!

same!😂

When you just clicked on here to learn about the universe and realised, "OMG! It's Science Short guy! The ultimate GCSE life saver!!!"

Your nenooo made me chuckle..😂

Your Neowww sound reminds me of a dank memes

I thought you quit doing these videos, but thank god you're back!

Thank you! Been waiting for this one 🙌

I’m gonna watch your videos even after my exams. Thanks for all the help :D

Thank you so much for this topic. The videos have been helpful in the best way possible and your method is incredibly easy to understand and it didn't bore me at all!

“That means they must be bookin it away from us.” 😂

I’ve been struggling and dying through physics Revision so Your sounds made me chuckle

Just finished watching your gcse vectors video, it was helpful, thanks, please upload more gcse science videos. Subscribed.

thank you. You're saving my grade 🙌🏼

This video is soooo helpfully for understanding the baicis of the big bang for my uin course !

Human audible range is from 20 Hz to 20kHz. So if 1 Hz is used, we won't be able to hear the sound.

Great video!

PLEASE DO A VIDEO ON relative speeds of approach and separation! Thank you very much

Thank you so much

Thanks!

Thanks I understand it now!

@science sir can u explain with reference to the formula that is used for dopplers efffect??

This was so helpful, thank you!

Hahah this is soooo cute 'neno neno neno'!

Nice ambulance impression

as I was watching the beginning of this video, an ambulance drove past

surely you find the centre of the universe from how far away and how fast galaxies are moving and in which direction then you can determine whether more galaxies are being made at the centre to see if Big Bang theory is true

so if you were following not too far behind the ambulance at the same speed would the sound be pitched down as it is for a stationary Observer? because the waves are still being created further apart in space wavelength is increasing but you are also reaching the waves quicker

Nah the sound wouldn’t change

you’re so accurate I love it😂😂😂

Can I ask a question? If the universe is expanding, is the energy actually being conserved?

It's all nonsense mate.

can someone explain this that would be very helpful in any direction, the farthest galaxies away from us are the ones that are traveling the fastest away from us.

I have a question if the sun only emits visible light of certain wavelengths, why are we still seeing white instead of, for example, brown light?

cos of photoreceptors in our cones/retina

What is past the end of the universe then? Why is it "cooling" down? Why would it not just keep expanding at the same rate??

Is this on every exam board in a level

Yes and no. No, your school has an option to learn either astrophysics (this), medical physics, engineering Physics, Turning points or Electronics as the extra topic that will appear in paper 3 A level physics. Yes, every exam board has these extra sections to choose from that are compulsory. These videos here are for AQA but I'm guessing the content will be similar for OCR and Edexel as well.

neeeeow~~

neeeeeeeeeeeeeeoooooooooooowwwwwwwwwwwwwwwwwwww

is it possible that distant stars are composed of different elements than the sun which emit different wavelengths of light causing us to believe it's been redshifted when it really hasn't?

@ScienceShorts

Nope. But there is the 'tired light' theory - that light is changed as it passes through many gravitational wells on the way to us 🤷‍♂️

Your basically assuming the earth is at the centre of the universe...

This doesn't need that assumption. There is however other evidence that suggests this is the case.

@stevebrown9693

The evidence suggests there is relative separation between us and the other galaxies, but that could mean we are moving away from them, there is no way to figure out who is the one moving, because there is nothing absolute to measure it against
