What is the universe expanding into? - Sajan Saini

The universe began in a Big Bang nearly fourteen billion years ago, and has been expanding ever since. But how does the universe expand and what is it expanding into? Sajan Saini explains the existing theories around the Big Bang and what, if anything, lies beyond our universe.

Lesson by Sajan Saini, directed by Wooden Plane Productions.

what's funny with knowledge is that the more you acquire, the more you realise you lack a HUGE chunk of it; hence it could be our eternal quest

[Heather-fxsr]

“So that’s our answer: the universe expands unto itself, ” she says, as though that makes any sense

[PowahSlapEntertainmint]

The universe needs to give us some...space.

[icarus]

I can't even imagine what the "outside" of space is like. I mean, space is an empty void, right? So how can a void be absent of emptiness?? And I can't imagine how space is expanding because how can "nothing" expand? What is "nothing" to begin with? Is there a state of nothingness that is more severe than "nothing"?

God, I should be sleeping right now.

I‘ve always thought of it as the universe just expands into a higher dimension.

Just think about how a 2D-Plane takes up no „space“ (volume) in a 3D-Room. So you could put an infinite amount of 2D-Planes into an infinitely small 3D-Room.

This is true for higher (spatial) dimensions as well. Thus our 3D-Universe could expand into a 4D-Room/Space which itself is inside a 5D-Room in a 6D-Room and so on and so on...

Thus our universe is „located“ in an infinitely high dimension which is infinitely small.

But nobody knows the real answer so just my two cents on this question.

Everytime I hear about the creation of the universe, it gives me goosebumps

[TamaraTkacova]

I’m genuinely trying to understand what‘s happening in the second half of the video but my brain just starts overheating every time😂😂

Ted-Ed is an amazing channel. I always smile when I see Ted-Ed has uploaded because it means I get to learn something new! I hope they never stop uploading.

[Chrisratata]

The big bang is still bangin' *to this day!*

[arkyadas]

I am so addicted to existential questioning videos on TED-ED, i need rehab

[SussyBacca]

"these aren't just wild guesses" then they proceed to tell you the most widely talked about wild guesses

[sivaforutube]

"The Universe is expanding unto itself"

[Kharonerz]

I like how she sounds so confident talking about theories and hypothesis...

[TinOutofTen]

I love the music in this video... It sets a mystery-evoking mood.

[benign]

Reason why I adore science (mostly physics) is of things like this. Can't wait to go to sixth form and Uni :)

[anamikapathak]

I love this channel. Its the best channel on YouTube. I can just binge watch ted ed videos.❤️

[manishp]

The more I see such videos on universe, the more complex everything becomes to comprehend!

[strange_and_magnificent]

Thanks you so much TED Ed, your videos never disappoint me!

Question: If we are a part of the universe, is my body, house, earth, sun, and Galaxy also expanding? This video makes it sound like only the space between things is expanding. The raisins are a part of the bread/universe right? Would that mean they are both expanding together?

[yeeeee]

My theory,
The universe is just one big baking loaf of rasin bread. Galaxies are rasins, the air inside is antimatter and the bread itself is space. The universe is transforming into a juicy loaf bread to satisfy the craving of a bigger, higher form of species, maybe celestial maybe gods...
