If the Universe Expands, What Is It Expanding Into?

[@Gravitating]

Most of these videos promise much with their shocking headlines but, very few actually deliver. This one makes a genuine attempt to explain things in a rational and logical way, without resorting to regurgitating endless, random facts that explain nothing. One of the better ones I've seen..

[@ragingpwner241]

Was hoping for Cliff notes on this one because I think about this concept ask the time. I knew this video wasn't going to answer anything. Only makes my faith in a huge being stronger.

I found the ballon analogy v helpful

is the pizza still free if Dominos can't get there in 30 minutes....even if the person who called is moving away at nearly the speed of light?

[@MrEnjoivolcom1]

A math equation for the ages!

[@larrymarkowitz8386]

Doesn’t your question imply that Dominoes also moves at the speed of light? There’s something wrong with the theory, I suspect.

[@generaladmiral90]

I found the narrative and visuals very relaxing and well our together

[@mitchellbrown1425]

It is wild to think about humans reversing the expansion of the universe with some kind of technology, that would almost in a way make us like G0d Imagine the negative consequences that could have. Space is the most amazing subject to learn about but also frustrating because we can never really know fully each detail as we want to and all the crazy relationships in the universe.

[@spikehawley6682]

So the small things stay together, im guessing die to gravity. Does that make dark energy = anti gravity? If its pushing things apart

[@lynnepaquette4124]

What a beautiful video and you explain this really well. Thank you.

[@hedlamp1497]

it iis a fractal. All the maths adds up it is a fractal. When the galaxies gat far enough apart, they provide the space to allow a new galaxy to be born. Like drops on a pond.

[@nigelbutler5040]

Obviously, you forgot about the accuracy of measurements of distant objects. Hubble can be wrong.... His assumptions are not openly discussed

[@sethprice241]

Do you think that the entire scientific community for over 100 years has been taking it on faith that Hubble was right?

[@StanTheObserver-lo8rx]

Well you left out that we might make entanglement a way to travel the Universe instantly-then to other Universes like our own. We might also find a way to tap into the huge energy levels of space itself. We then would surf the dark energy,always ahead of it. Easy.

[@sillygoose2619]

As expected the comment section is full of idiots and science deniers. The end of this world cant come soon enough. This video was fantastic. Great work on it!

[@sethprice241]

Idiots indeed. Who would have thought that all the information in the history of the world at your fingertips would have made everyone dumber. It boggles the mind.

[@brennannewman6726]

More universe is there.

[@tye829]

I've always been very unsatisfied with the explanation that the universe is expanding... So astronomers say that they can tell things are spreading out, they can observe the redshift, right... I get all that. That makes sense. What doesn't make sense is how they extrapolate this to conclude that the _entire_ universe is expanding. How do they know this isn't something that's only happening locally? Why wouldn't they just conclude that the _observable_ universe is expanding? Maybe there's a good answer I just haven't heard, but the conclusion that the _entire_ universe expanding seems like a bit of a leap if the explanation is just that they can see everything spreading out... does not seem very scientific to conclude that without more evidence.

[@sethprice241]

The observable universe and the known universe are one and the same. We don't know what we can't see. So they are reporting on what we know to be true. Anything beyond what we can see is simply speculation. When they say, the universe is expanding, they mean everything that we know of, is expanding. 'Locally' doesn't exist in the context of everything.

[@chrisbfd]

If all galaxies are moving away from each other, why is the Andromeda galaxy colliding with the Milky way?

[@dr.rickmarshall6697]

Because we are in a group of galaxies called our local group and the forces of gravity still affect these local groups of galaxies to interact with one another ,as we are still expanding away from other groups . if you think about it it’s like a little bubbles ,in our local group is one bubble with the gravity still attracting one another to each other ,that’s how you have galaxies that merge like our own has done before and will do again. I’m sure there’s somebody that can explain it better than me, but that’s the best I can do. Hope that gives you the general idea.

[@chrisbfd]

@dr.rickmarshall6697 yes, thank you.

[@mightT1]

yeah space isn't expanding... everything is just shrinking in space at the same rate.

[@dexter8705]

Why do you think everything is shrinking?

[@rustypedals7869]

Well 99.9999% of every atom is empty space, so you're proposing that the fundamental forces that hold the structuce of atoms are changing in a way that reduces the empty void uniformly over time. Maybe darkmatter is consuming the energy of matter? A fun idea 🎉

[@Aluminata]

As there is nothing that anything can travel through faster than light, and the universe is expanding faster than light. It can only be one thing. That is to say - NOTHING!

[@dirtbird7415]

Space is expanding into the Universe , whats so hard about that. Big bang created local spacetime not the universe.

Spock could figure it out.

[@dumby88]

such a missleading title. It could be like askin : whats north of the north pole.

[@tylerjones477]

If the universe truly was expanding faster than speed of light then it would be impossible for Andromeda to collide with us or for that matter for any galaxy to collide because they are supposedly moving away faster than light but yet some how Andromeda brakes laws of physics and moves faster than rate of expansion oooookkkkkk!!?

[@rockNrolla130]

Expansion adds up over distance

[@mirostsiklauri577]

Its pointless we never understood the universe 💯 % but we must try harder end harder that's how we evolved 😊

[@Facts_Are_Facts_Are_Facts]

Maybe everything is shrinking.

[@dexter8705]

Why do you think that?

[@Facts_Are_Facts_Are_Facts]

@dexter8705 Without a point of reference, it could be true. Why not? Truth is often stranger than fiction.

[@dexter8705]

@@Facts_Are_Facts_Are_Facts I believe space is "expanding " inwards 😂 specifically into matter, in the form of gravity, that's why I found you comment interesting. People always ask what it expanding into, so my answer would be matter, by form of gravity. So relative to my opinion your answers not exactly wrong.

[@dantetomic7049]

We are having a very hard time getting to the moon and staying there for more than a few hours, and yet here we are speculating about the size of the universe. The universe has been around infinitely long and will be around infinitely more. We are trapped inside our world just like goldfish are trapped inside a glass bowl with no idea how we got here and where we are heading. The Earth could be a planet spaceship,traveling through space and carrying us and all Earths creatures to another dimension. Documentaries like these are nice, but full of speculation.

If the universe is expanding, why am I not expanding? Or am I?

[@dexter8705]

THe universe isn't expanding but space is stretching, it's called gravity.. hurry up and catch up.

[@sillygoose2619]

This video explains why space is expanding, and why gravity has little power to stop it. Catch up.

[@dexter8705]

@sillygoose2619 😂 So spaghettification happens at the centre of our galaxy, and spaghettification happens at the next galaxy, this stretching of space that causes spaghettification also happens everywhere inbetween those galaxies. Gravity stretch's space.. keep up slow poke

[@SeauxNOLALady]

The concept of an infinite universe that is constantly expanding which means that every possible scenario can exist and will exist. Like a version of me that lives my exact life in every single way exists somewhere in the universe, or that other version of me is living life with slight changes, or massive changes. Maybe I am a billionaire and have cured cancer and am a queen of the whole planet. But I digress… The point is that the universe is so inconceivably vast that the human mind is incapable of comprehending it in a meaningful way. Just the concept of infinite is hard to grasp. I hope humanity can develop technology that allows us to travel across the expanse of space and become an intergalactic society and possibly discover intelligent life on a distant world, but not eradicate it like we tend to do
